FUNCTION OF THE COLLECTION UNIT
The collection unit is made up of the preceding filter, charging electrode and collecting electrode.
1. Preceding filter
The preceding filter is made of a non-woven polyester fabric. Suspended particles and cut chips are removed, and coarse oil mist is absorbed. The absorbed oil mist condenses into droplets, which then fall to
the bottom of the unit. An airflow rectification screen has been included to provide an even flow of air to
the entire surface of the filter and to enhance collection efficiency.
2. Charging electrode
This electrode applies a high voltage charge to the oil mist that passes through the preceding filter.
The EM-15e has one charging electrode, while the EM-30e has two charging electrodes.
3. Collecting electrode
This electrode absorbs the oil mist that has been charged by the charging electrode with the application
of high voltage.
The EM-15e has one collecting electrode, while the EM-30e has two collecting electrodes.
– 4 – 3. INSTALLATION
When installing the mist collector, observe the following items. If not observed, the mist collector could be
damaged or the efficiency could be lowered.
Install the unit indoors where it will not be exposed to direct sunlight or rain.

 Install where it will not be affect by strong vibrations or shocks.
 Install the unit horizontally, or the collected oil will not drain out normally and this will cause problems.
 Place the unit on a strong floor surface that can support its mass. If it is suspended from the ceiling,
make sure to secure it to the ceiling with strong mounting bolts, etc.
 When the unit is moved, make sure to have a qualified person move it.
 Use screws and bolts no longer than 20mm when installing the intake onto the unit.

80 cm min.
– 6 – 4. PREPARATION
Caution for installing an oil drainage duct
The waste oil outlet comes installed with a plug to prevent dust and debris from entering the unit during shipping. Be sure to remove this plug
before attaching an oil drainage duct. (See the operation manual for
details.)
Caution:
Do not operate this unit without removing the plug from the waste
oil outlet. Failure to do so could cause mist to leak out of the discharge side.
Remove the plug.
PREPARATION FOR OIL DRAINAGE
When installing the mist collector, set the pipes so that the oil can be drained normally. If this is not done the
oil could accumulate at the bottom of the unit and then overflow or splatter out of the drain hole. To prepare
for oil drainage, attach the hose to the drain hole at the bottom front of the unit, following the procedure below.
Piping from drain hole to oil pan
Please use the hose nipple and the elbow joint in
accessories of this unit and prepare an appropriate hose for the hose nipple which has inner diameter φ 25mm.
Elbow joint
Hose nipple
200mm min.
NOTE
Add enough oil to the oil pan so that the end
of the hose is not left open to the air.
If the end of the hose is above the surface
of the oil, it will draw in air, then the accumulated oil could get sucked into the interior of
the unit and blown out of the drain hole.
100mm min.
Put in same oil as mist.
When setting pipes as shown above, the oil drain normally without any air being drawn into the drain hole.
NOTE
When bending the hose, be careful that the hose does not get pinched. If it does, normal drainage will
not be possible.
We recommend that the hose diameter be as large as possible in order to reduce the possibility of the
oil clogging. (Recommended inner diameter of hose: φ25mm)
If it is necessary to use any other items of equipment for waste oil treatment, please contact the dealer
where the unit was purchased, or a dealer or sales office of AMANO.

Make electrode inspection, on charging electrodes and collecting electrodes, according to the following
procedure.
① Perform one and more times of inspection every week.
Take out the electrodes and check each electrode plate for dirt on the surfaces and freedom of any deformation, at least once every week. If excessive dirt accumulation is found, carry out the cleaning according to ③ below. If any part of the electrode is distorted, make a replacement.
– 20 – ② Perform cleaning at the detection of a 2mm thick dirt accumulation.
Carry out cleaning if the thickest dirt deposit on the electrode metal plates exceeds 2mm. Excessive dirt deposition could cause a fire to occur.
③ Clean the electrodes one and more times every 3 months.
Regardless of the presence or absence of a dirt deposit
on the electrodes, carry out electrode cleaning at least
once every 3 months. The cleaning procedure will be explained in the next section.
Expanded view of electrode:
As the interval between the electrode metal plates
becomes narrower due to dirt accumulation thereon, spark discharge becomes more liable to occur,
which could cause a fire to occur.

• Be careful not to deform the feed spring attached to the charging electrode. This could cause accidents or damage the equipment.
• After cleaning the needle electrodes removed from the charging electrode, reinstall all needle electrodes properly. At this time, make sure you do not bend the discharge needles on the needle electrodes. (See next page “Replacing the Charging Electrode and Collecting Electrode”.)
Use the following procedure to clean the charging electrode.
① Hold the metal plate flange between your fingers and
gently pull it out.
② Pour solvent cleaner into a tray and soak the collecting
electrode in it.
③ Scrape off the dirt with a toothbrush or similar small
brush. The charging electrode will have the most dirt
around the discharge needles. Even after cleaning, a
resin-like residue may still remain. This residue does not
have to be removed by force.
④ Rinse it in cool or warm water.
⑤ Dry it completely. Using an electrode that is still wet can
cause accidents or breakdowns. Also check to see that
there is no foreign material and that the electrode plate is
not deformed or bent.

CAUTION
• Be careful not to cut your fingers or hands on the flange of the metal plate.
• Wear rubber gloves and safety glasses when performing cleaning.
• For installing and removing the collecting electrode, follow the procedure and observe warnings and precautions given in this section.
CAUTION
• Do not distort the feed spring attached to the collecting electrode. This could cause accidents or dam-
age the equipment.
Follow the procedure given below to clean the collecting electrode.
① Hold the metal plate flange between your fingers and
gently pull it out.
② Unscrew the 4 screws that secure the top plate of the col-
lecting electrode.
③ Pour solvent cleaner into a tray and soak the collecting
electrode in it.
④ Scrape off the dirt with a toothbrush or similar small
brush.
⑤ Rinse it in water or hot water.
Be sure that no foreign substance remains between the

CHECK AND REPLACE THE CHARGING ELECTRODE/COLLECTING ELECTRODE
CAUTION
When replacing the needle electrodes, be careful not to cut your fingers or hands.
For installation and removal of the charging/collecting electrode, follow the procedure and observe warnings and precautions given in this section.
NOTE
• When replacing the needle electrodes, note that there are 9 sets of needle electrodes for 1 charging electrode.
• Do not attempt to repair the collecting electrode. This could cause accidents or breakdowns.
Check and replace the Charging Electrode (Needle Electrode)
As the operating time progresses, the needles of the needle
electrodes get dirty and become liable to discharge abnormal
sparks. When the needles have got dirty remarkably, they
must be cleaned with a detergent effective for oily and fat
stains. If abnormal spark discharge should still be observed
after such cleaning, they need replacing with new ones. It is
also necessary to check needles periodically for any deformation or non-uniformity in the length (all needles must be
extended 14mm outward on both sides from the edge of the
needle electrode to the respective needle tips), and to replace
with new ones appropriately.
① Unscrew the inspection cover of the body unit to pull out
the charged electrode unit.
Retainer spring
② Unhook needle electrodes one by one. Check each retainer spring for freedom of deformation and elongation,
and replace with a new one, if any.
– 23 – ③ Check needle electrodes; clean or replace at need.
• Check each needle electrode for any deformation or biased installation. If any, abnormal discharge of sparks could be caused.
• Check and see if any foreign substance or waste fabric clings to needles, which could cause abnormal discharge of sparks.
• Make sure that the needles are of uniform length.
Deformation of needle; foreign substance
(fabric thread) clinging to needle tip
Deformed needle electrode
④ Follow the steps below to install the needle electrodes.
1) Set the spring hook on one side of the retainer spring in the small hole in a needle electrode.
2) Set the spring hook on other side of that retainer spring
in the small hole in the charge electrode unit.
3) Set the hook at the opposite end of the relevant needle
electrode in the groove in the charged electrode unit.
• Make sure the needle electrodes are installed at reglar
intervals. If not, abnormal sparks may be dis charged.
Needles must not be deformed and
should be installed at regular intervals.
⑤ Set the charged electrode unit back into the body unit.
⑥ Put on the inspection cover and secure with screws.
– 24 – Hook
 Replacing the Charging Electrode (*Discharge Wire Electrode)
The discharge wire electrodes are consumable parts that will deteriorate to be easily broken with years of
use. If you find a sag or fracture in any of them, immediately replace it with new one.
NOTE
Replacement of the discharge wire electrodes must be performed if a lack of tension or any damage to
the wire is detected visually, or fragility of the wire is detected on inspection by touch.
* The discharge wire electrode is available as an option.
• Removal
Remove the discharge wire electrode to be replaced from
the charging electrode. At this time, check also the support spring for any deformation, excessive wear or damages, and replace with new one, if necessary.
Support Spring
• Installation
Hook the head of the support spring through the small hole in the discharge wire electrode for replacement. Hook on the bottom of that support spring to the small hole in the charging electrode main frame.
Set the hook at the other end of the discharge wire electrode into the groove in the charging electrode
main frame, opposite to the support spring side.
Hook on the groove.
– 25 – • Sag in the discharge wire electrode
When installing the discharge wire electrode in the charging electrode main frame, make sure that the replaced wire electrode has no sagging or twisting, being a main cause of spark discharge.
Whenever any spark discharge is observed during the operation, the relevant discharge wire electrode
must immediately be replaced with a new one. If the cause should be attributable to the deformation in
the charging electrode main frame, the charging electrode must be replaced.
Sagging
Twisting
• Contamination of discharge wire electrodes
Check and ensure no flocks are on and around the discharge wire electrodes. Remove if any, since they could
cause an abnormal discharge.
Replacing the collecting electrode
CAUTION
Observe cautions given at page 19 when you install and remove the collecting electrode.
If a collecting electrode becomes deformed or damaged,
replace it with a new one. Using a damaged electrode could
cause an abnormal spark discharge.
Never attempt to repair and re-use a collecting electrode.
This could cause an accident or a reduction in collecting
efficiency.
