Components
Before unit start-up, read all manuals and
become familiar with unit components
and operation. Thoroughly check the unit
before operating.
For A-Coil installations, it is recommended
that coil be sprayed with liquid detergent
thoroughly and rinsed thoroughly before
installation to assure proper drainage of
condensate from the coil fins to eliminate
water blowoff and to assure maximum coil
performance. If not sprayed approximately
50 hours of break in time is required to
achieve the same results.
Master Contactor: Energizes Compressor
and optional Hydronic Pump and/or
Desuperheater pump package.
Logic Board: Logic Board operates the
compressor and protects unit by locking out
when safety switches are engaged. It also
provides fault indicator(s).
Terminal Strip: Provides connection to the
thermostat or other accessories to the low
voltage circuit.
⚠ CAUTION ⚠
Transformer: Converts incoming (source)
voltage to 24V AC.
ALL GEOTHERMAL EQUIPMENT IS
DESIGNED FOR INDOOR INSTALLATION
ONLY. DO NOT INSTALL OR STORE UNIT
IN A CORROSIVE ENVIRONMENT OR IN
A LOCATION WHERE TEMPERATURE AND

Section 3: Installation Considerations
Consumer Instructions: Dealer should
instruct the consumer in proper operation,
maintenance, filter replacements, thermostat
and indicator lights. Also provide the consumer
with the manufacturer’s Owner's Manual for the
equipment being installed.
Thermostat: Thermostats should be installed
approximately 54 inches off the floor on an
inside wall in the return air pattern and where
they are not in direct sunlight at anytime.
Loop Pumping Modules: Must be wired to the
heat pump’s electric control box. A special
entrance knockout is provided below the
thermostat entrance knockout. A pump
module connection block, connected to
the master contactor, and circuit breaker is
provided to connect the Pump Module wiring.
Enertech Global D-I-Y Policy: Enertech Global’s
geothermal heat pumps and system installations
may include electrical, refrigerant and/or water
connections. Federal, state and local codes
and regulations apply to various aspects of the
installation. Improperly installed equipment can
lead to equipment failure and health/safety
concerns. For these reasons, only qualified
technicians should install a Enertech Global built
geothermal system.
Desuperheater Package: Water heating is
standard on all residential units (units may be
ordered without). It uses excess heat during
both heating and cooling cycles, to provide
hot water for domestic needs. A double wall
desuperheater exchanger (coil) located
between the compressor and the reversing
valve, extracts superheated vapor to heat
domestic water; still satisfying its heating and
cooling needs. The water circulation pump
comes pre-mounted in all residential units, but
must be electrically connected to the master
contactor. Leaving it disconnected ensures that
the pump will not run without a water supply.
Because of the importance of proper
installation, Enertech Global does not sell
equipment direct to homeowners. Internet
websites and HVAC outlets may allow for
purchases directly by homeowners and doit-yourselfers, but Enertech Global offers no
warranty on equipment that is purchased via
the internet or installed by persons without
proper training.
Enertech Global has set forth this policy
to ensure installations of Enertech Global
geothermal systems are done safely and
properly. The use of well-trained, qualified
technicians helps ensure that your system
provides many years of comfort and savings.
The Desuperheater package can make up to
60% (depending on heat pump usage) of most
domestic water needs, but a water heater is still
recommended.
Desuperheater Piping: All copper tubes
& fittings should be 5/8” O.D (1/2” nom)
minimum with a maximum of 50ft separation.
Piping should be insulated with 3/8” wall
closed cell insulation.
Equipment Installation: Special care should
be taken in locating the unit. All units should
be placed on a formed plastic air pad, or
a high density, closed cell polystyrene pad
slightly larger than the base of the unit. All units
should be located in an indoor area were
the ambient temperature will remain above
55°F and should be located in a way that
piping and ductwork or other permanently
installed fixtures do not have to be removed for
servicing and filter replacement.
Note: Copper is the only approved material
for piping the desuperheater.
Electrical: All wiring, line and low voltage,
should comply with the manufacturer's
recommendations, The National Electrical
Code, and all local codes and ordinances.

Section 3: Operation Considerations
Guidelines For Heating Mode Operation For Water-To-Water Units Using Scroll Compressors
Enertech recommends the aquastat setting not be set above 110°F for the storage tank
temperature. Excessive vibration and part failure can occur at higher than recommended
temperature settings. The higher operating temperatures cause substantial efficiency and
capacity reductions.
The performance is negatively affected as the unit operates at the higher water temperatures
and it benefits the unit and the homeowner to operate at or below the recommended water
temperature of 110°F.
With the lower efficiency created by higher water temperatures, the output capacity of the
unit is decreased along with the efficiency. When operating at the higher entering water
temperature the heat of extraction is significantly reduced, as well. In order to maintain the
needed capacity, more of the heat is coming from the compressor working harder to compress
the refrigerant.
The illustration below shows the parameters which are safe for compressor operation. Based
on the leaving load water of 120°F, the loop would have to maintain 35°F to operate within
the acceptable operating conditions for the compressor. Once your loop temperatures drop
below 35°F, the acceptable leaving load temperature drops below 120°F. If you are designing
loops for 30°F, the recommended leaving load temperature is 110°F.

Source Entering Water Temperature
Because the water-to-water machines have become so popular for providing heated water for
a multitude of uses, we’ve provided the above chart for reference.
The obvious correlation is that the warmer the Source Entering Water Temperature, the hotter
the Load Leaving Water Temperature can be, to a point. R410A can only handle up to about
125°F Load Leaving Water Temperature before putting the compressor at risk.
Actual usage, and choices of heat distribution devices need to follow the acceptable
operating conditions presented in the chart. If a question arises, please consult the Technical
Services Department.

Section 3: Buffer Tanks
BUFFER TANKS
Virtually all water-to-water heat pumps used
for hydronic applications require a buffer tank
to prevent equipment short cycling, and to
allow lower flow rates through the water-towater unit than through the hydronic delivery
system. The following are considerations for
buffer tank sizing.
stage. Requirements for storage are less
according to the manufacturer of the HSS series
non-pressurized buffer tank. Using the same
conditions for maximum heating and cooling
capacity mentioned above, non-pressurized
buffer tanks require 6 U.S. gallons per ton.
• The size of the buffer tank should be
determined based upon the predominant
use of the water-to-water equipment
(heating or cooling).
• The size of the buffer tank is based upon the
lowest operating stage of the equipment.
For example, a water-to-water heat
pump with a two-stage compressor or two
compressors may be sized for first stage
capacity, reducing the size of the tank (twostage aquastat required).
• Pressurized buffer tanks are sized differently
than non-pressurized tanks (see guidelines
listed below).
Pressurized buffer tanks for predominately
heating applications should be sized at one (1)
U.S. gallon per 1,000 Btuh of heating capacity
(10 gallons per ton may also be used) at the
maximum entering source water temperature
(EST) and the minimum entering load water
temperature (ELT), the point at which the waterto-water unit has the highest heating capacity,
usually 50-70°F EST and 80-90°F ELT.
For predominately cooling applications,
pressurized buffer tanks should be sized at
one (1) U.S. gallon per 1,000 Btuh of cooling
capacity (10 U.S. gallons per ton may also be
used) at the minimum EST and the maximum
ELT, the point at which the water-to-water unit
has the highest cooling capacity, usually 5070°F EST and 50-60°F ELT.
Select the size of the tank based upon the
larger of the calculations (heating or cooling).
Non-pressurized buffer tanks must also be sized
based upon predominate use (heating or
cooling) and based upon the lowest capacity

Section 4: Unit Placement
UNIT PLACEMENT
When installing a geothermal heating and
cooling unit, there are several items the installer
should consider before placing the equipment.
1.
2.
3.
4.
Service Access. Is there enough space for
service access? A general rule of thumb is
at least 2 feet in the front and 2 feet on at
least one side.
Unit Air Pad. All geothermal heating and
cooling equipment should be placed on
either a formed plastic air pad, or a high
density, closed cell polystyrene pad. This
helps eliminate vibration noise that could
be transmitted through the floor.
If units are being placed on racking, the
unit must be placed on a solid foundation
covering the full base of the unit. Also,
utilize a foam pad between the unit and
the rack.
The installer must verify that all applicable
wiring, piping, and accessories are correct
and on the job site.
PRE-INSTALLATION
Before you fully install the geothermal
equipment, it is recommended you go
through this quick checklist before placing the
equipment.
⧠
⧠
Fully inspect the unit after unpacking.
Locate the Unit Start-Up form from this
manual and have it available as the unit
installation proceeds.
HYDRONIC AIR HANDLER INSTALLATION
These units have a 0” minimum clearance to
combustible materials rating from all cabinet
surfaces. The unit should be i9nstalled with
serviceability clearance of 30” from the front
of the unit. The unit can be serviced entirely
from the front, including replacing the filter.
Be sure and route primary and secondary
drain connections so as not to obstruct
replacement of filter.
UPFLOW APPLICATION
In an upflow installation the discharge outlet
is at the top. Care should be taken to insure
unit is level to permit proper condensate
drainage.
Normal upflow installation will be in a
basement or closet. If installed in a closet,
the closet should have a platform framed in,
with an opening on top of the platform
centered in the closet.
Connect the supply air outlet to a warm air
plenum. Install return air grilles from outside
the closet to space below the platform.
Platform must be at least 10” above the
floor. If installed in a basement, run supply
and return ductwork in accordance with
local codes.
Caution! A “P” trap must be installed in the
coil drain line! Cap unused drain fittings.
HORIZONTAL APPLICATION
Horizontal application will normally be used
in an attic or crawl space. This type of
installation requires a return air duct be
attached to the unit inlet. The opposite end
of the return air duct is attached to a return
air filter grill through the ceiling or wall.
Remove filter from unit if filter grill is used. The
unit is shipped in right to left configuration.
For left to right applications (Begin with
the unit in the verticl upright poisition and
before connecting drains and refrigerant
lines) remove coil and doors and move
horizontal pan to right side. Reinstall coil and
doors.
CAUTION: IT IS MANDATORY TO USE AN
EMERGENCY AUXILLARY DRAIN PAN WITH
ANY COIL OR AIR HANDLER INSTALLED IN AN
ATTIC OR ABOVE A FINISHED CEILING!
DOWNFLOW APPLICATION
Contact Enertech for proper downflow kit
including instructions.
Unit is shipped from the factory arranged to
be installed in a vertical upflow or horizontal
right to left airflow position (standard) or field
convertible to a horizontal left to right airflow
position.

Open Loop Piping
Placement of the components for an open
loop system are important when considering
water quality and long term maintenance. The
water solenoid valve should always be placed
on the outlet of the heat pump, which will keep
the heat exchanger under pressure when the
unit is not operating. If the heat exchanger is
under pressure, minerals will stay in suspension.
Water solenoid valves are also designed to
close against the pressure, not with the pressure.
Otherwise, they tend to be noisy when closing.
velocity noise. Always double check flow rate
at the P/T ports to make sure the ball valve
adjustments have not lowered water flow too
much, and essentially taken the flow regulator
out of the equation. It’s a good idea to remove
the ball valve handles once the system is
completed to avoid nuisance service calls.
A flow regulator should be placed after the
water solenoid valve. Always check the product
specification catalog for proper flow rate. A
calculation must be made to determine the
flow rate, so that the leaving water temperature
does not have the possibility of freezing.
Since the heat pump can operate at lower
waterflow on first stage, two stage units
typically include two water solenoid valves
to save water. The flow regulators should be
sized so that when one valve is open the unit
operates at first stage flow rate, and when
both valves are open, the unit operates at
full load flow rate. For example, a 4 ton unit
needs approximately 4 GPM on first stage, and
approximately 7 GPM at full load. The flow
regulator after the first valve should be 4 GPM,
and the flow regulator after the second valve
should be 3 GPM. When both valves are open,
the unit will operate at 7 GPM.
Other necessary components include a strainer,
boiler drains for heat exchanger flushing, P/T
ports and ball valves. Ball valves allow the
water to be shut off for service, and also help
when velocity noise is noticeable through the
flow regulator. Spreading some of the pressure
drop across the ball valves will lessen the
Hose kits are optional, but make for an easier
installation, since the P/T ports and connections
are included. The hose also helps to isolate the
heat pump from the piping system.

Water Quality
The quality of the water used in geothermal
systems is very important. In closed loop systems
the dilution water (water mixed with antifreeze)
must be of high quality to ensure adequate
corrosion protection. Water of poor quality
contains ions that make the fluid “hard” and
corrosive. Calcium and magnesium hardness
ions build up as scale on the walls of the system
and reduce heat transfer. These ions may also
react with the corrosion inhibitors in glycol based
heat transfer fluids, causing them to precipitate
out of solution and rendering the inhibitors
ineffective in protecting against corrosion. In
addition, high concentrations of corrosive ions,
such as chloride and sulfate, will eat through any
protective layer that the corrosion inhibitors form
on the walls of the system.
Ideally, de-ionized water should be used for
dilution with antifreeze solutions since de-
ionizing removes both corrosive and hardness
ions. Distilled water and zeolite softened water
are also acceptable. Softened water, although
free of hardness ions, may actually have
increased concentrations of corrosive ions and,
therefore, its quality must be monitored. It is
recommended that dilution water contain less
than 100 PPM calcium carbonate or less than
25 PPM calcium plus magnesium ions; and less
than 25 PPM chloride or sulfate ions.
In an open loop system the water quality is
of no less importance. Due to the inherent
variation of the supply water, it should be tested
prior to making the decision to use an open
loop system. Scaling of the heat exchanger
and corrosion of the internal parts are two of
the potential problems. The Department of
Natural Resources or your local municipality
can direct you to the proper testing agency.

Interior Piping
All interior piping must be sized for proper flow
rates and pressure loss. Insulation should be
used on all inside piping when minimum loop
temperatures are expected to be less than
50°F. Use the table below for insulation sizes with
different pipe sizes. All pipe insulation should
be a closed cell and have a minimum wall
thickness of 3/8”. All piping insulation should
be glued and sealed to prevent condensation
and dripping. Interior piping may consist of the
following materials: HDPE, copper, brass, or
rubber hose (hose kit only). PVC is not allowed
on pressurized systems.
Typical Pressurized Flow Center Installation
The flow centers are insulated and contain
all flushing and circulation connections for
residential and light commercial earth loops
that require a flow rate of no more than 20
gpm. 1-1/4” fusion x 1” double o-ring fittings
(AGA6PES) are furnished with the double
o-ring flow centers for HDPE loop constructions.
Various fittings are available for the double
o-ring flow centers for different connections.
See figure 2 for connection options. A typical
installation will require the use of a hose kit.
Matching hose kits come with double o-ring
adapters to transition to 1” hose connection.

Typical Non-Pressurized Flow Center Installation
Standing column flow centers are designed to
operate with no static pressure on the earth
loop. The design is such that the column of
water in the flow center is enough pressure to
prime the pumps for proper system operation
and pump reliability. The flow center does have
a cap/seal, so it is still a closed system, where the
fluid will not evaporate. If the earth loop header
is external, the loop system will still need to be
flushed with a purge cart. The non-pressurized
flow center needs to be isolated from the flush
cart during flushing because the flow center
is not designed to handle pressure. Since this
is a non-pressurized system, the interior piping
can incorporate all the above-mentioned pipe
material options (see interior piping), including
PVC. The flow center can be mounted to the
wall with the included bracket or mounted on
the floor as long as it is properly supported.

Convenience: Is the antifreeze available and
easy to transport and install?
Antifreeze Overview
In areas where minimum entering loop
temperatures drop below 40°F, or where piping
will be routed through areas subject to freezing,
antifreeze is required. Alcohols and glycols
are commonly used as antifreeze. However,
local and state/provincial codes supersede
any instructions in this document. The system
needs antifreeze to protect the coaxial heat
exchanger from freezing and rupturing.
Freeze protection should be maintained to
15°F below the lowest expected entering
loop temperature. For example, if 30°F is the
minimum expected entering loop temperature,
the leaving loop temperature could be 22
to 25°F. Freeze protection should be set at
15°F (30-15 = 15°F). To determine antifreeze
requirements, calculate how much volume
the system holds. Then, calculate how much
antifreeze will be needed by determining
the percentage of antifreeze required for
proper freeze protection. See Tables 3a
and 3b for volumes and percentages. The
freeze protection should be checked during
installation using the proper hydrometer
to measure the specific gravity and freeze
protection level of the solution.
Codes: Will the brine meet local and state/
provincial codes?
The following are some general observations
about the types of brines presently being used:
Methanol: Wood grain alcohol that is
considered toxic in pure form. It has good heat
transfer, low viscosity, is non-corrosive, and is mid
to low price. The biggest down side is that it is
flammable in concentrations greater than 25%.
Ethanol: Grain alcohol, which by the ATF
(Alcohol, Tobacco, Firearms) department
of the U.S. government, is required to be
denatured and rendered unfit to drink. It has
good heat transfer, mid to high price, is noncorrosive, non-toxic even in its pure form, and
has medium viscosity. It also is flammable with
concentrations greater than 25%. Note that
the brand of ethanol is very important. Make
sure it has been formulated for the geothermal
industry. Some of the denaturants are not
compatible with HDPE pipe (for example,
solutions denatured with gasoline).
Antifreeze Characteristics
Selection of the antifreeze solution for closed
loop systems require the consideration of
many important factors, which have long-term
implications on the performance and life of
the equipment. Each area of concern leads to
a different “best choice” of antifreeze. There
is no “perfect” antifreeze. Some of the factors
to consider are as follows (Brine = antifreeze
solution including water):
Safety: The toxicity and flammability of the brine
(especially in a pure form).
Cost: Prices vary widely.
Thermal Performance: The heat transfer and
viscosity effect of the brine.
Corrosiveness: The brine must be compatible
with the system materials.
Stability: Will the brine require periodic change
out or maintenance?
Enertech Global
Propylene Glycol: Non-toxic, non-corrosive,
mid to high price, poor heat transfer, high
viscosity when cold, and can introduce micro
air bubbles when adding to the system. It
has also been known to form a “slime-type”
coating inside the pipe. Food grade glycol is
recommended because some of the other
types have certain inhibitors that react poorly
with geothermal systems. A 25% brine solution is
a minimum required by glycol manufacturers,
so that bacteria does not start to form.
Ethylene Glycol: Considered toxic and is not
recommended for use in earth loop applications.
GS4 (POTASSIUM ACETATE): Considered highly
corrosive (especially if air is present in the
system) and has a very low surface tension,
which causes leaks through most mechanical
fittings. This brine is not recommended for use in
earth loop applications.

Antifreeze Charging
Calculate the total amount of pipe in the
system and use Table 3a to calculate the
amount of volume for each specific section of
the system. Add the entire volume together,
and multiply that volume by the proper
antifreeze percentage needed (Table 3b)
for the freeze protection required in your
area. Then, double check calculations during
installation with the proper hydrometer and
specific gravity chart (Figure 6) to determine if
the correct amount of antifreeze was added.

Section 8: Controls
MICROPROCESSOR FEATURES AND OPERATION
Enertech Global geothermal heat pump
controls provide a unique modular approach
for controlling heat pump operation. The
control system uses one, two, or three printed
circuit boards, depending upon the features
of a particular unit. This approach simplifies
installation and troubleshooting, and eliminates
features that are not applicable for some units.
solenoid valve, or a 24VAC solenoid valve
with an end switch. Additional field wiring is no
longer required for operation of the end switch.
A microprocessor-based printed circuit board
controls the inputs to the unit as well as outputs
for status mode, faults, and diagnostics. A
status LED and an LED for each fault is provided
for diagnostics.
Removable low voltage terminal strips provide
all necessary terminals for field connections.
Not only are the thermostat inputs included,
but there are also removable terminal strips
for all of the accessory wiring for ease of
installation and troubleshooting.
Startup/Random Start
The unit will not operate until all the inputs
and safety controls are checked for normal
conditions. At first power-up, the compressor is
energized after a five minute delay. In addition,
a zero to sixty second random start delay is
added at first power-up to avoid multiple units
from being energized at the same time.
Short Cycle Protection
A built-in five minute anti-short cycle
timer provides short cycle protection of
the compressor.
Component Sequencing Delays
Components are sequenced and delayed for
optimum space conditioning performance and
to make any startup noise less noticeable.
Test Mode
The microprocessor control allows the
technician to shorten most timing delays for
faster diagnostics by changing the position of a
jumper located on the lockout board.
Water Solenoid Valve Connections
Two accessory relay outputs at the terminal
strip provide a field connection for two types
of water solenoid valves, a standard 24VAC
Enertech Global
Loop Pump Circuit Breakers
The loop pump(s) and desuperheater pump
on single compressor units are protected
by control box mounted circuit breakers
for easy wiring of pumps during installation.
Dual compressor units only protect the
desuperheater pump but do not protect the
loop or load side pumps. All loop and load side
pumps must be wired externally using relays
and circuit breakers supplied by others. Circuit
breakers eliminate the need to replace fuses.
Safety Controls
The control receives separate signals for high
pressure, low pressure, and low water flow. Upon
a continuous 30-second measurement of the
fault (immediate for high pressure), compressor
operation is suspended (see Fault Retry below),
and the appropriate LED flashes. Once the unit
is locked out (see Fault Retry below), an output
(terminal “L”) is made available to a fault LED
at the thermostat (water-to-water unit has fault
LED on the corner post).
Low Pressure: If the low pressure switch is open
for 30 continuous seconds, the compressor
operation will be interrupted, and the control
will go into fault retry mode. At startup, the low
pressure switch is not monitored for 90 seconds
to avoid nuisance faults.
High Pressure: If the high pressure switch
opens, the compressor operation will be
interrupted, and the control will go into fault
retry mode. There is no delay from the time the
switch opens and the board goes into fault
retry mode. There is also no delay of switch
monitoring at startup.
Flow Switch: If the flow switch is open for 30
continuous seconds, the compressor operation
will be interrupted, and the control will go into
fault retry mode. At startup, the flow switch
is not monitored for 30 seconds to avoid
nuisance faults.
FAULT RETRY
26
WT Models, Rev.: B
Section 8: Controls
All faults are retried twice before finally locking
the unit out. The fault retry feature is designed to
prevent nuisance service calls. There is an antishort cycle period between fault retries. On the
third fault, the board will go into lockout mode.
Over/Under Voltage Shutdown
The lockout board protects the compressor
from operating when an over/under voltage condition exists. The control monitors
secondary voltage (24VAC) to determine if
an over/under voltage condition is occurring on the primary side of the transformer.
For example, if the secondary voltage is
18VAC, the primary voltage for a 240V unit
would be approximately 180V, which is
below the minimum voltage (197V) recommended by the compressor manufacturer.
Under voltage (<18VAC) causes the compressor to disengage and restart when the
voltage returns to >20VAC. Over voltage
(>31VAC) causes the compressor to disengage and restart when the voltage returns
to <29VAC.
When an O/U Voltage condition occurs,
the board will initiate a fault, shut down the
compressor, and start the five minute ASC
Table 4a: LED Identification
period. All four fault LEDs will flash (HP + LP
+ FS + CO) and the thermostat “Call For
Service” indicator will be illuminated. This
feature is self-resetting. If voltage returns to
normal range normal operation will resume
if/when the ASC period is over (except if in
lockout mode). If voltage is still out of range
at the end of the ASC period the control
will execute a Fault Retry. On the third fault
within 30 minutes, the board will go into
lockout mode and illuminate the “Call For
Service” indicator. When normal operation
is restored the four fault LED’s will stop flashing and the “Call For Service” indicator will
turn off.
Intelligent Reset
If the thermostat is powered off and back
on (soft reset), the board will reset, but the
last fault will be stored in memory for ease of
troubleshooting. If power is interrupted to the
board, the fault memory will be cleared.
Diagnostics
The lockout board includes five LEDs (status,
high pressure, low pressure, low water flow,
condensate overflow) for fast and simple
control board diagnosis. Below is a table
showing LED function.

Test Mode (TEST): When the TEST jumper is
installed, the board operates in the normal mode.
When the jumper is removed, the board operates
in test mode, which speeds up all delays for easier
troubleshooting. When service is complete, the
jumper must be re-installed in order to make sure
that the unit operates with normal sequencing
delays. While test jumper is removed, the status

seconds after the “Y1” input is received.
Over/Under Voltage Disable (O/V): When the
O/V jumper is installed, the over/under voltage
feature is active. When the jumper is removed,
the over/under voltage feature is disabled. On
rare occasions, variations in voltage will be
outside the range of the over/under voltage
feature, which may require removal of the
jumper. However, removal of the jumper could
cause the unit to run under adverse conditions,
and therefore should not be removed without
contacting technical services. An over/under
voltage condition could cause premature
component failure or damage to the unit
controls. Any condition that would cause this
fault must be thoroughly investigated before
taking any action regarding the jumper removal.

NOTES:
1. Dehumidification mode can be enabled by cutting the jumper on the ECM board. When cut, cooling CFM is reduced by 15%, and heating/auxiliary heat CFM remains
unchanged. Example: Model 036 with HEAT and COOL jumpers on C setting and ADJUST jumper on Norm setting would run at 1115 CFM with jumper cut, instead
of 1308 CFM with jumper intact.
1. Gray shaded areas are recommended settings. Other settings may be used, depending upon application. DO NOT cut dehumidification jumper if CFM setting will
cause airflow to be below 250 CFM per ton on first stage, and below 325 CFM per ton on second stage. Example: Model 036 should not run below 750 CFM in first
stage, or below 975 CFM in second stage. 2. The COOL and HEAT jumpers should both be set at the same position. COOL controls heating and cooling airflow; HEAT controls electric heat airflow.
3. Above CFM will be maintained up to 0.50” ESP for models MPH024 and 036, and up to 0.75” ESP for models MPH048 and 60.

size
Auxiliary electric heaters are
wired and installed correctly
Circulating pumps are wired and
fused (if necessary) correctly
Desuperheater pump is NOT
wired, unless piping is complete
and all air is purged
Low voltage wiring is correct and
completely installed
Plumbing:
Pipe and pump sizes are correct
Air is purged from all lines
Antifreeze is installed
All valves are open, including

Equipment Start-Up
1. Energize geothermal unit with
high voltage.
2. Set the thermostat to “Heat” or
“Cool.” Adjust set point to
energize the unit. System will
energize after delays expire
(typically a five minute delay).
3. Check water flow with a flow
meter (non-pressurized) or
pressure drop conversion
(pressurized). Pressure drop
tables must be used to convert
the pressure drop to GPM. The
pressure drop can be obtained by
checking water pressure in and
water pressure out at the P/T
ports.
4. Check the geothermal unit’s
electrical readings listed in the
Unit Electrical Data table.
5. Check the source water
temperature in and out at the P/T
ports (use insertion probe). Allow
10 minutes of operation before
recording temperature drop.
6. Calculate the heat of extraction or
heat of rejection.
7. Check the temperature difference
of the load coax (water-to-water)
or air coil (water-to-air). P/T ports
are recommended for use on the
load side, but the line
temperatures can be used to
check the temperature difference.
8. Change the mode of the
thermostat and adjust the set
point to energize the unit. Check
the data in opposite mode as the
previous tests. Amp draws as
well as temperature differences
and flow rate should be recorded.
9. Check auxiliary heat operation by
adjusting the thermostat set point
5°F above the room temperature
in “Heat” mode or set thermostat
to “Emergency." Record voltage,
amperage, and air temperature
difference.
PERFORMANCE CHECK:
Heat of Extraction(HE)/Rejection(HR)
Record information on the Unit Start-up Form
Equipment should be in operation for a
minimum of 10 minutes in either mode – WITH
THE HOT WATER GENERATOR TURNED OFF.
A 10% variance from Spec Manual is allowed.
Always use the same pressure gauge &
temperature measuring device.
Water flow must be in range of Specification
Manual. If system has too much water flow,
performance problems should be expected
1. Determine flow rate in gallons per minute
a. Check entering water temperature
b. Check entering water pressure
c. Check leaving water pressure
Once this information is recorded, find
corresponding entering water temperature
column in Specification Manual for unit.
Find pressure differential in PSI column in Spec
Manual. Then read the GPM column in Spec
Manual to determine flow in GPM.
2. Check leaving water temperature of unit.

Check fuse size, replace fuse or reset circuit breaker.
Check low voltage circuit breaker.
Low Voltage Circuit
Check 24 volt transformer. If burned out or less than 24 volt, replace. Before replacing, verify tap setting
and correct if necessary.
Water Flow (runs for 30 sec)
If water flow is low (less than 3.5 GPM), unit will not start. Make sure Pump Module or solenoid valve is
connected (see wiring diagram). Water has to flow through the heat exchanger in the right direction (see
labels at water fitting connections) before the compressor can start. If water flow is at normal flow, use an
ohmmeter to check if you get continuity at the flow switch. If no switch is open and flow is a normal flow,
remove switch and check for stuck particles or bad switch.
B: UNIT RUNNING NORMAL, BUT SPACE TEMPERATURE IS UNSTABLE
Thermostat
Thermostat is getting a draft of cold or warm air. Make sure that the wall or hole used to run thermostat
wire from the ceiling or basement is sealed, so no draft can come to the thermostat.

C: NO WATER FLOW
Pump Module
Make sure Pump Module is connected to the control box relay (check all electrical connections). For nonpressurized systems, check water level in Pump Module. If full of water, check pump. Close valve on the
pump flanges and loosen pump. Take off pump and see if there is an obstruction in the pump. If pump is
defective, replace. For pressurized systems, check loop pressure. Repressurize if necessary. May require
re-flushing if there is air in the loop.
Solenoid valve
Make sure solenoid valve is connected. Check solenoid. If defective, replace.
D: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOW
Water
Water flow & temperature insufficient.
Load Side Flow
Check speed setting, check nameplate or data manual for proper speed, and correct speed setting.
Check for dirty air filter—Clean or replace.
Restricted or leaky ductwork. Repair.
Refrigerant charge
Refrigerant charge low, causing inefficient operation. Make adjustments only after airflow and water flow
are checked.
Reversing valve
Defective reversing valve can create bypass of refrigerant to suction side of compressor. Switch reversing
valve to heating and cooling mode rapidly. If problem is not resolved, replace valve. Wrap the valve with a
wet cloth and direct the heat away from the valve. Excessive heat can damage the valve. Always use dry
nitrogen when brazing. Replace filter/drier any time the circuit is opened.
E: IN HEATING OR COOLING MODE, UNIT OUTPUT IS LOW
Heat pump will not cool but will
heat. Heat pump will not heat
but will cool.
Reversing valve does not shift. Check reversing valve wiring. If wired wrong, correct wiring. If reversing
valve is stuck, replace valve. Wrap the valve with a wet cloth and direct the heat away from the valve.
Excessive heat can damage the valve. Always use dry nitrogen when brazing. Replace filter/drier any time
the circuit is opened.
Water heat exchanger
Check for high-pressure drop, or low temperature drop across the coil. It could be scaled. If scaled, clean
with condenser coil cleaner.

Notes:
1. All line and low voltage wiring must adhere to the National Electrical Code and Local Codes, whichever is the most stringent.
2. Wire length based on a one way measurement with a 2% voltage drop.
3. Wire size based on 60°C copper conductor and minimum circuit ampacity.
4. All fuses class RK-5
* The external loop pump FLA is based on a maximum of three UP26-116F-230V pumps (1/2hp) for 048 - 060 and two pumps for 034
Proper Power Supply Evaluation: When any compressor bearing unit is connected to a weak power supply, starting current will generate
a significant “sag” in the voltage reducing the starting torque of the compressor motor increasing the start time. This will influence the rest of the
electrical system in the building by lowering the voltage to the lights. This momentary low voltage causes “light dimming”. The total electrical system
should be evaluated by an electrician and HVAC technician. The evaluation should include connections, sizes of wires, and size of the distribution
panel between the unit and the utility’s connection. The transformer connection and sizing should be evaluated by the electric utility provider.
⚠ CAUTION ⚠
CHECK COMPRESSOR AMP DRAW TO VERIFY COMPRESSOR ROTATION ON THREE PHASE UNITS. COMPARE AGAINST
UNIT ELECTRICAL TABLES. REVERSE ROTATION RESULTS IN HIGHER SOUND LEVELS, LOWER AMP DRAW, AND INCREASED
COMPRESSOR WEAR. THE COMPRESSOR INTERNAL OVERLOAD WILL TRIP AFTER A SHORT PERIOD OF OPERATION.

Source Water Flow Selection
Proper flow rate is crucial for reliable operation of geothermal heat
pumps. The performance data shows three flow rates for each entering
water temperature (EST column). The general “rule of thumb” when
selecting flow rates is the following:
Top flow rate: Open loop systems (1.5 to 2.0 gpm per ton)
Middle flow rate: Minimum closed loop system flow rate
(2.25 to 2.50 gpm/ton)
Bottom flow rate: Nominal (optimum) closed loop system flow rate
(3.0 gpm/ton)
Although the “rule of thumb” is adequate in most areas of North
America, it is important to consider the application type before applying
this “rule of thumb.” Antifreeze is generally required for all closed loop
(geothermal) applications. Extreme Southern U.S. locations are the
only exception. Open loop (well water) systems cannot use antifreeze,
and must have enough flow rate in order to avoid freezing conditions at
the Leaving Source Water Temperature (LWT) connection.
Calculations must be made for all systems without antifreeze to determine if the top flow rate is adequate to prevent LWT at or near freezing
conditions. The following steps should taken in making this calculation:
Determine minimum EST based upon your geographical area.
Go to the performance data table for the heat pump model selected and
look up the the Heat of Extraction (HE) at the “rule of thumb” water flow
rate (GPM) and at the design Entering Load Temperature (ELT).
Calculate the temperature difference (TD) based upon the HE and GPM
of the model.
TD = HE / (GPM x 500).
Calculate the LWT.
LWT = EST - TD.
If the LWT is below 35-38°F, there is potential for freezing conditions if
the flow rate or water temperature is less than ideal conditions, and the
flow rate must be increased.
Example 1:
EST = 50°F, ELT = 95°F.
Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 33,600 Btuh.
TD = 33,600 / (5 x 500) = 13.4°F
LWT = 50 - 13.4 = 36.6°F
Water flow rate should be adequate under these conditions.
Example 2:
EST = 40°F, ELT = 95°F.
Model 036 Full Load, heating. Flow rate = 5 GPM. HE = 28,700 Btuh.
TD = 28,700 / (5 x 500) = 11.5°F
LWT = 40 - 11.5 = 28.5°F
Water flow rate must be increased.
Application Notes for Performance Data
Notes:
1. Desuperheater Capacity is based upon 0.4 GPM Flow per nominal ton at 90°F entering hot water temperature.
2. Extrapolation data down to 25°F for heating and interpolation between EST & GPM data is permissible.
3. EWT (Entering Water Temperature) is also called EST (Entering Source Temperature).
4. Load flow rate is the same as the nominal source flow rate, approximately 3 GPM per ton.
