correctly to the Australian standards do not place it into
service. If any problems or questions arise during the
installation that cannot be answered in this installation
manual please call the relevant local authorities or the
Electrolux service centre (number located in the warranty
section of this manual).
The heat pump has been charged with refrigerant and does not
require any on-site installation of refrigeration components.
caution
Installing the hot water system in any of the following places
may lead to malfunction of the system.
• Sites containing mineral oils such as cutting lubricant.
• Locations beside the sea where salt air can cause
corrosion.
• Locations near hot springs where corrosive gases exist,
e.g., sulfide gas.
• Factories where the supply voltage fluctuates markedly.
• Inside a cabin or caravan.
• Kitchens where oil permeates the air.
• Places where strong electromagnetic radiation exists.
Choosing a suitable installation location
The hot water storage tank can be installed either indoors or
outdoors however the heat pump must be installed outdoors
only. The heat pump is designed to operate within the
temperature range of -7°C to 50°C, ensure the site chosen is
within this ambient temperature range.
Please ensure the following:
1. Enough space for installation and maintenance is
available around the hot water system.
2. The height difference between the water outlet of the
heat pump and water inlet of the water tank will be less
than 5 metres.
3. The air inlet and outlet of the heat pump will be free from
obstacles and sheltered from strong winds.
4. The bearing surface is level, can bear the full weight of
the hot water system, and is suitable for installing the
heat pump without increasing noise or vibration.
5. The operational noise of the heat pump will not affect
occupants and neighbours.
6. No flammable items stored near the installation site.
• Places where flammable gases or materials exist.
• Places where acid or alkali gases evaporate.
If installing the heat pump in cyclonic areas or areas where
high levels of wind exist, ensure the mounting solution and
fixing is adequate. If possible, avoid installing the heat pump
at elevated heights in these areas and instead place it in a
more sheltered position at ground level.

Installation
Precautions before installing
1. Decide the correct way to transport the hot water system.
2. Transport the hot water system in its original packaging
to avoid damage.
3. Ensure the heat pump is kept upright at all times,
including during transportation.
NOTE: Please confirm the mounting fixtures are strong enough
and mounted firmly if the heat pump unit is to be installed on
an external wall. If leakage of water from the hot water system
has potential to cause property damage, a properly drained safe
tray is to be installed under the heat pump and/or storage tank.
Frost protection
This hot water system can operate in frosty conditions down
to -7C when the following important installation requirements
are followed:
Ensure adequate insulation is installed on all exposed
connections, pipe work and hoses (minimum thickness 20mm).
The heat pump must be installed on continuous only power
supply so that power is available at all times in order for the
frost protection mechanism to operate.
The inlet valves and storage tank should be installed inside
if possible.
The relief valve piping must be installed in a frost free
environment in order to remain open to atmosphere at all times.
Electric heater tape is recommended to be installed
underneath piping insulation in extreme frost areas.
Water quality
Water quality can vary in different locations and affect the
performance and safe operation of the hot water system.
If the water supply is not within the acceptable limits as
indicated below, the hot water system should not be
installed, and may not be covered by the Electrolux warranty.
A suitable solution is to implement a water pre-treatment
process to bring the water quality to within acceptable limits
to support the installation.
The saturation index (SI) is a measure of the corrosive or
scaling properties of the water supply. Corrosive water (SI<1.0) can corrode copper components. In these conditions
warranty will not apply. Scaling water (SI>0.5) can cause
build up of CaCO3 (Calcium carbonate) which can impact
to the correct operation of moving parts within the system,
including the temperature and pressure relief valve. In these
conditions warranty may not apply.
Total Dissolved Solids (TDS) and water hardness can also
impact the life of the hot water system, and warranty does
not apply outside the following limits:
• TDS exceeding 600 p.p.m
• Electrical conductivity exceeding 850us/cm
• Total hardness exceeding 200 p.p.m
• Chloride exceeding 250 p.p.m
• Magnesium exceeding 10 p.p.m
• Sodium exceeding 150 p.p.m
• Acidity/Alkalinity must also be within the limits of
pH 6.5 - 8.5
If this hot water system is installed in a regional location
where regular flushing is required due to sediment build up,
then a drain cock for flushing must be fitted at the time of
installation. If in doubt, consult your plumber.
Placing of heat pump and storage tank
The heat pump and storage tank must be installed on a level
surface and checked with a spirit level. The storage tank in
particular must be level to ensure the correct positioning
of the anode inside the tank and to prevent premature
breakage. Level installation will also ensure that hot water
is drawn from the top of the tank and will assist air being
dispelled during commissioning.
Heat pump placement and fixing
The heat pump may be installed mounted to a wall on a
bracket or on the ground. It must be fixed securely in place
and the rubber feet provided with the heat pump are to be
placed on the heat pump’s footings to dampen vibration.
Ensure that the mounting location is capable of handling
the full weight of the system and its components when filled
with water, refer specifications tables on pages 4 to 5 for full
weight details. If installing in a cyclone prone area, ensure
that the fixing methods are appropriate.

Water may leak from the heat pump due to condensation
and this is part of normal operation. A drain elbow has been
provided with the heat pump and shall be installed, along
with a drain hose, if necessary. If the hot water system is
positioned where leakage could cause property damage,
install suitable drained safe-trays where appropriate.
Connections and piping of the hot water system
Connections on the heat pump and the storage tank are
all 3/4”.
Storage tank inlet connections
An isolating and non return valve must be installed on the
inlet to the hot water system. If the supply pressure may

Heat pump connections
This hot water system may deliver hot water between 47C to
60C during normal operation. Any pipes delivering hot water
to the premises are to be installed with sufficient piping
insulation to maintain the efficiency of the hot water system
and to prevent heat loss. It is recommended that a heat
trap be installed on the outlet piping of the storage tank to
minimize convective heat loss. The supplied tempering valve
must be installed in order to temper any water that travels to
fixtures primarily used for the purposes of personal hygiene
(e.g. bathroom or ensuite fixtures) down to 50°C as required
by AS/NZS 3500.4.
The heat pump can be installed up to 5 metres away from
the storage tank (only 1 meter of hose is supplied). If the
heat pump is to be installed further than 1m away, run hard
copper piping from the tank to a point near the heat pump.
Use the hoses supplied to connect from the heat pump to
the hard plumbing in order to dampen vibrations on the
circulating water piping from heat pump vibration. The
hoses and any additional piping between the heat pump and
storage tank must have 20mm thick insulation covering them
to maintain the efficiency of the system. The hoses supplied
in the heat pump connection kit KSEHPKA must be used and
old hoses are not to be re-used. Under no circumstances
should an isolation valve be installed on the hoses or
connections between the heat pump and the storage tank.
outlet
The circulating water inlet connection to the heat pump is to
be plumbed to the flow connection on the storage tank. The
circulating water outlet connection on the heat pump must
be plumbed to the return connection on the storage tank.

Filling with water and dispelling air from the system
At this stage the wiring to the hot water system should either
be disconnected at the switchboard or have the power
isolated to it (off). Once all plumbing connections have been
made to the hot water system, it will need to be filled with
water and pressurized in order to check for leaks and to
dispel air from the system.
Activate the lever on the relief valve located on the
storage tank.

Electrical connection
recommended size of the conduit to the heat pump is 25mm
due to the number and size of the cables required to connect
to the hot water system. A junction box or tee piece will need
to be installed in order for one conduit to go to the heat pump
and one to the storage tank. The storage tank has provision
for a 20mm conduit adapter and a 25mm to 20mm reducer
may need to be installed at the junction box or tee piece. It is
recommended that an isolator be installed that can disconnect
each power supply to the heat pump simultaneously, to assist
in maintenance and shut down of the hot water system, this
however, is not mandatory.
Electrical wiring
The heat pump hot water system must be installed in
accordance with the AS/NZS 3000 wiring rules, the local
electrical authority regulations and any other applicable
standards. The pipe work, storage tank and heat pump are
to be properly connected to the earthing system of the
premises in accordance with AS/NZS 3000. The fixed wiring
must be protected by insulating sleeving with the appropriate
temperature rating and a means for disconnection must be
incorporated into the wiring.
The heat pump hot water system has the capability to be
wired on a standard continuous power supply or with an
additional off-peak supply if this is available at the premises.
The heat pump requires a continuous power supply in both
conditions in order to power the electronics that control the
heat pump, to ensure it has freeze protection and to allow
the auxiliary heating boost function to operate at any time
of the day. The continuous supply cable must be capable of
handling the current required to power the 3.6kW element in
the storage tank.
Depending on the wiring configuration, two or three cables will
be wired to the heat pump. The power supply cable(s) will be
run from the switchboard to the heat pump whilst the storage
tank heater cable will be run between the storage tank and the
heat pump. All cables will need to pass through a junction box,
tee piece or isolator in order to branch off to their separate
locations. If this heat pump hot water system is replacing an
existing electric hot water system, a power supply cable may
already be available for use. An additional active wire may need
to be run from the switchboard as required in order to give the
heat pump a continuous or an off-peak power supply.
For safety reasons it is recommended that the wiring of the
heat pump and storage tank be completed first before the
cables are wired to the switchboard. If you are replacing an
existing electric hot water system and re-using the existing
cable, ensure that the power supply to this cable is isolated or
disconnected at the switchboard.
warning
In order to avoid a hazard due to inadvertent resetting of
the heat pump's protective cut-outs, the continuous supply
must not be supplied through an external switching device
such as a timer, or connected to a circuit that is regularly
switched on and off by the utility.
Wiring the heat pump
If an off-peak power supply is connected to the heat pump,
it will only operate its automatic heating function when the
off-peak power supply becomes available. The heat pump
has been designed to operate on extended off-peak which is
available up to 18 hours of the day compared to the standard
off-peak which is available only 8 hours. The off-peak power
supply cable must be capable of handling the current required
to operate the 1.95kW compressor circuit of the heat pump.
All cables are to be passed through the cable clamp inside
the terminal box and the clamp securely fastened so that if
the conduit or cables are pulled, no stress is placed on the
terminal connections.
For safety reasons, all earths are to be connected first and
wired to the G terminal.
The continuous power supply input and the storage tank
heater output cables must both be capable of handling the
current draw of the 3.6kW element. The active wire of the
continuous supply input must be wired to the “HL” terminal
and the neutral wire to the HN terminal.
Note: Please refer to the AS/NZS 3008 standard for the current
carrying capacity of the cables to be used to ensure that they
are capable of handling the current draw of the heat pump in
the conditions that they are to be installed in.

If the heat pump is to be wired to a continuous power supply
only, the jumper leads supplied with the heat pump are to
be installed. The red jumper lead is to be wired between
terminals HL and L2. The black jumper lead is to be wired
between terminals HN and N2. This will provide power to
the compressor circuit of the heat pump and is shown in the
diagram below.

Wiring the heat pump with an off-peak power supply:
If the heat pump is to be wired with an off peak power supply,
there are a number of ways that this can be achieved. The off
peak power supply active wire is always to be wired to terminal
L2, however the off peak power supply cable could be a single
active wire, or have a neutral and an earth wire. The neutral
wire, if available, would be wired to terminal N2 however in the
case of the having a single active wire, the black jumper lead will
need to be installed between terminals HN and N2. These two
off peak wiring configurations are shown in the diagram.

If the heat pump is replacing an electric hot water system
that has an off peak power supply cable, another alternative
is running a single active cable for the continuous power
supply from the switchboard. In this case the black jumper
lead will also be installed between terminals HN and N2 and
the wiring configuration will look similar to the “off-peak wiring
configuration 1" in the diagram. Since the continuous power
supply would be using the off-peak supply cable’s neutral, it
must be capable of handling the current drawn by the 3.6kW
heating element. If in doubt, run a cable from the switchboard
with an adequately sized active and a neutral.
Note: The two operating modes of the heat pump, Automatic
mode and Electric heating manual mode will never operate at
the same time. Therefore if you are using a shared neutral for
the continuous and off peak power supplies, the maximum
current flowing through the neutral will be achieved when the
heat pump is in Electric heating manual mode and powering
the 3.6kW element in the storage tank.

Heat pump fuse rating
Wiring the hot water system to the switchboard:
There is a 5A 250V T5AL 20mm glass cylinder type fuse
located on the printed circuit board of the heat pump.
The hot water system is required to be connected to the
earthing system of the premises and to the earth stake. Each
earth wire is to be wired to the earthing terminal inside the
switchboard. The active wire of each power supply to the heat
pump is required to be connected to an appropriately rated
and labelled circuit breaker and the circuit breakers must be
located next to each other. The neutral wires must
be connected to the unprotected neutral bar.
Wiring the hot water storage tank:
The 20mm conduit adapter is to be inserted into the 20mm
cut-out provided and the locking ring screwed down to hold
the conduit firmly in place.
The earth wire is to be wired to the earthing terminal on the
bottom left hand side of the terminal block. The active is to be
wired to terminal “A1” and the neutral to terminal “N” of the
wiring terminal block.

Electrical testing of the heat pump hot water system
Once the hot water system has been filled with water, the
following mandatory tests are required to be completed as per
the AS/NZS 3000 Australian Standards:
a) Continuity of the earthing system
b) Insulation resistance
c)Polarity
d) Correct circuit connections
e) Verification of impedance required for automatic
disconnection of supply
Note: The heat pump is required to be electrically
disconnected during the insulation resistance testing to
prevent damage to its electronics.

Refer to the AS/NZS 3000 Australian Standard for specific
details on how to perform these tests and the acceptable
readings that must be obtained. If the electrical installation
fails a test, that test and any preceding tests that may have
been influenced by the fault indicated shall be repeated after
the fault has been rectified.
Temperature sensor connection
The heat pump requires feedback of the water temperature
inside the storage tank in order to determine when it needs
to operate. To achieve this the temperature sensor (supplied
with the heat pump) is required to be run between the heat
pump and the storage tank. It is recommended that the sensor
cable be neatly cable tied to the conduit or pipe work that
runs between the storage tank and heat pump. Any excess
cable should be neatly tied in a loop and kept out of the
way. However, if it is a possibility that the sensor cable could
become damaged during the life of the hot water system, it is
recommended that it be protected by installation in a conduit
or similar protective means.
Installing the temperature sensor in the storage tank
The copper end of the sensor cable is the temperature
sensing device and is to be installed in the sensor pocket
located at the “return” connection on the storage tank. When
inserting the sensor into the sensor pocket, ensure that it
is inserted all the way into the pocket and reaches the end.
Install the plug and fix the clamp to the sensor pocket using
the screws provided. This will prevent the temperature sensor
from being pulled out of the pocket and seals it from the
outside environment.
Connecting the sensor cable at the heat pump
Inside the heat pump’s terminal box is a female plug socket
that the male plug end of the sensor cable plugs into. Push the
male plug into the female socket until it clicks into place.

Commissioning
Commissioning must only be commenced once the
installation has been completed according to the relevant
Australian standards and the instructions in this manual.
Confirm the following before operation:
• The heat pump has been installed correctly
• Air inlet and outlet of heat pump are free of obstacles
• Relief valve(s) installed correctly
• Drainage piping installed correctly
• Supplied tempering valve is installed correctly
• All water connections are correct
• Piping insulation has been installed
• Inlet valve is fully open
3. Once the heat pump has stopped and the tank is up to
temperature, drain some water off using a hot tap inside
and then operate the auxiliary boost button. Monitor
and confirm the operation of the tank element and
thermostat.
4. Once the hot water system is up to temperature, check
that hot water is available to all hot taps or fixtures in the
house and there is sufficient flow or pressure. Ensure that
any fixtures designed primarily for purposes of personal
hygiene do not have hot water above 50°C coming from
them and adjust the tempering valve as necessary.
5. Clean any filters that are installed in the water system of
the premises or at the individual fixtures as they may have
become blocked by debris during the installation and
commissioning of the hot water system.
• Water is not leaking from the hot water system
• Air has been bled from the storage tank and heat pump
• Temperature sensor installed correctly in sensor pocket
• Electrical cables installed correctly
• Wiring configuration is correct
• Electrical testing has been completed and satisfactory result obtained
• Power supply is either continuous or extended off peak
The following steps are to be followed after the installation
of the heat pump hot water system to ensure its safety and
performance. If the hot water system cannot be setup to
perform correctly as specified in this manual, please call the
service centre for further instructions (number located in the
warranty section of this manual).
1. Turn on the power supply to the hot water system. If it has
been installed on an off peak power supply it may need
to be temporarily wired to a continuous power supply for
commissioning.
2. Allow the heat pump to run and monitor its operation
until the water in the storage tank reaches the set point
temperature and the heat pump shuts down. This may
take a few hours depending on the size of the storage
tank and the conditions at the time.
Note: If the heap pump does not begin operating after
a few minutes despite power being supplied to the heat
pump and the tank water being cold, the auxillary heating
boost button may have accidently been pressed during
commissioning or installation whilst the heat pump was
powered up. In this case, switch off the power supply
(both if connected to seperate continuous and off peak 2
power supply) for 2 minutes, then switch power back on
again to reset to normal heat pump operation. After a few
minutes the heat pump should start to operate.
To force the heat pump to operate, remove the lid on the
heat pump and carefully press and hold the two buttons
marked "force" and "query" on the printed circuit board.
The circulating pump should start and after one minute
the heat pump will begin to operate.
18 commissioning Kelvinator heat pump hot water system
Now that commissioning has been completed and the heat
pump hot water system has been set up to operate correctly,
select the correct model number of the storage tank on page
5 of the user manual. Fill out your details, the serial numbers,
installation date and any important notes for the customer.
The user manual is then to be handed to the customer or
left in a suitable location on the premises. If the customer is
available they should be instructed on the safe and correct
operation of the hot water system.
Note: If the heat pump hot water system needs to be
drained after commissioning please refer to the maintenance
section in the user manual supplied with the heat pump
for instructions.
