• While in compressor off, the indoor f an repeats low airflow speed and pause.

• While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidifica-

tion operation and 4-min compressor off repeat.
Compressor ON Temp. ➲ Setting Temp+0.5°C
Compressor OFF Temp. ➲ Setting Temp-0.5°C

• In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.

■ Heating Mode Operation

• When the intake air temp reaches +3°…above the setting temp, the compressor is turned off. When below
the setting temp, the compressor is turned on.
Compressor ON Temp. ➲ Setting Temp.
Compressor OFF Temp. ➲ Setting Temp.+3°C

• While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C, when above 28°C , it
operates with the low or setting airflow speed. When the indoor pipe temp is between 20°C and 28°C, it oper­ates with Super-Low(while in sleep mode, with the medium airflow speed).

• While in compressor off, the indoor fan is off when the indoor pipe temp is below 33°C, when above 35°C , it
operates with the low airflow speed.

• If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, the
outdoor fan is turned on/off according to the indoor pipe temp.

• While in defrost control, both of the indoor and outdoor fans are turned off.

■ Defrost Control

• While in heating mode operation in order to protect the evaporator pipe of the outdoor unit from freezing,
reversed to cooling cycle to defrost the evaporator pipe of the outdoor unit.

• After 40 min heating mode operation, at 4 min interval, whether to carry out defrost control or not and the time
of defrost control are determined according to the following conditions.

1) While in heating mode operation, the maximum of the indoor pipe temperature is measured and it is com-

pared with the present indoor pipe temperature to get the difference of the indoor pipe temperatures (=the
maximum temperature of indoor pipe ? the present temperature of indoor pipe), according to which, whether
to carry out defrost control or not is determined.

2) According to the need of defrost control shown above and the elapsed time of heating mode operation at that

moment, the defrost control time is determined.

3) When the determined time of defrost control is below 7 min, heating mode operation continues without carry-

ing out defrost control. According to the procedure stated above, the determination is made again. When the
defrost control time is 7 min or longer, defrost control is then carried out.

• While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the present
temp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of the
indoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost con­trol is completed and heating mode operation is carried out.

• While in defrost control, if the defrost time determined before the start of defrost control is completed, defrost
control stops and heating mode operation is carried out regardless of the above condition.

• When the indoor pipe temp is 42°C or above, defrost control is not carried out even if the condition is one of
the defrost conditions above.

• While in defrost control, the compressor is on and the indoor fan, the outdoor fan, and the 4 way valve are off.

high on the wall as possible, allowing a minimum of
"B" from ceiling.

• Use a stud finder to locate studs to prevent unneces­sary damage to the wall.

2. Outdoor unit

• If an awning is built over the unit to prevent direct sun­light or rain exposure, make sure that heat radiation
from the condenser is not restricted.

• Ensure that the space around the back and sides is
more than 10cm. The front of the unit should have
more than 70cm of space.

• Do not place animals and plants in the path of the
warm air.

• Take the air conditioner weight into account and select
a place where noise and vibration are minimum.

3) How to fix installation plate

The wall you select should be strong and solid enough
to prevent vibration

1. Mount the installation plate on the wall with four
type A screws. If mounting the unit on a concrete
wall, use anchor bolts.

• Mount the installation plate horizontally by aligning

the centerline using a level.

2. Measure the wall and mark the centerline. It is

also important to use caution concerning the
location of the installation plate-routing of the
wiring to power outlets is through the walls typi­cally. Drilling the hole through the wall for piping
connections must be done safely.

4) Drill a hole in the wall

• Drill the piping hole with a ø70mm hole core drill. Drill
the piping hole at either the right or the left with the
hole slightly slanted to the outdoor side.

2. Flaring Work and Connection of Piping

1) Flaring work

Main cause for refrigerant leakage is due to defect in the flaring
work. Carry out correct flaring work using the following procedure.

1. Cut the pipes and the cable.

• Use the piping kit accessory or pipes purchased locally.

• Measure the distance between the indoor and the

outdoor unit.

• Cut the pipes a little longer than the measured distance.

• Cut the cable 1.5m longer than the pipe length.

2. Burr removal

• Completely remove all burrs from the cut cross sec­tion of pipe/tube.

• Put the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid drop­ping burrs into the tubing.

3. Putting nut on

•

Remove flare nuts attached to indoor and outdoor unit, then
put them on pipe/tube having completed burr removal.
(not possible to put them on after flaring work)

4. Flaring work

• Firmly hold copper pipe in a die in the dimension
shown in the table above.

• Carry out flaring work using flaring tool as shown
below.

5. Check

• Compare the flared work with figure below.

• If flare is noted to be defective, cut off the flared sec-

tion and re-flare it.

2) Connection of piping Indoor

• Preparing the indoor unit's piping and drain hose for
installation through the wall.

• Remove the plastic tubing retainer(see illustration
below) and pull the tubing and drain hose away from
chassis.

•

Replace the plastic tubing holder in the original position.

4. Checking the Drainage and Forming the Pipings

1) Checking the drainage

1. To remove the front panel from the indoor unit.

• Set the air direction louvers up-and-down to the posi­tion(horizontally) by hand.

• Remove the securing screws that retain the front pan­el. Pull the lower left and right sides of the grille
toward you and lift it off.

2. To check the drainage.

• Pour a glass of water on the evaporator.

• Ensure the water flows through the drain hose of the

indoor unit without any leakage and goes out the drain
exit.

3. Drain piping

• The drain hose should point downward for easy drain
flow.

• Do not make drain piping.

2) Form the piping

1. Form the piping by wrapping the connecting por­tion of the indoor unit with insulation material and
secure it with two kinds of vinyl tapes.

• If you want to connect an additional drain hose, the
end of the drain outlet should be routed above the
ground. Secure the drain hose appropriately.

2. In cases where the outdoor unit is installed below
the indoor unit perform the following.

• Tape the piping, drain hose and connecting cable from
down to up.

• Secure the tapped piping along the exterior wall using
saddle or equivalent.

3. In cases where the Outdoor unit is installed above
the Indoor unit perform the following.

•

Tape the piping and connecting cable from down to up.

• Secure the taped piping along the exterior wall. Form
a trap to prevent water entering the room.

5. Air Purging

1) Air purging

Air and moisture remaining in the refrigerant system
have undesirable effects as indicated below.

• Pressure in the system rises.

• Operating current rises.

• Cooling(or heating) efficiency drops.

• Moisture in the refrigerant circuit may freeze and block

capillary tubing.

• Water may lead to corrosion of parts in the refrigera­tion system.

Therefore, the indoor unit and tubing between the
indoor and outdoor unit must be leak tested and evacu­ated to remove any noncondensables and moisture
from the system.

2) Air purging with vacuum pump

1. Preparation

• Check that each tube(both liquid and gas side tubes)
between the indoor and outdoor units have been prop­erly connected and all wiring for the test run has been
completed. Remove the service valve caps from both
the gas and the liquid side on the outdoor unit. Note
that both the liquid and the gas side service valves on
the outdoor unit are kept closed at this stage.

2. Leak test

• Connect the manifold valve(with pressure gauges)
and dry nitrogen gas cylinder to this service port with
charge hoses.

• Pressurize the system to no more than 150 P.S.I.G.
with dry nitrogen gas and close the cylinder valve
when the gauge reading reached 150 P.S.I.G. Next,
test for leaks with liquid soap.

• Do a leak test of all joints of the tubing(both indoor
and outdoor) and both gas and liquid side service
valves.
Bubbles indicate a leak. Be sure to wipe off the soap
with a clean cloth.

• After the system is found to be free of leaks, relieve
the nitrogen pressure by loosening the charge hose
connector at the nitrogen cylinder. When the system
pressure is reduced to normal, disconnect the hose
from the cylinder.

Be sure to use a manifold valve for air purging. If it is
not available, use a stop valve for this purpose. The
"Hi" knob of the manifold valve must always be kept
close.

CAUTION

To avoid nitrogen entering the refrigerant system in a
liquid state, the top of the cylinder must be higher than
its bottom when you pressurize the system. Usually,
the cylinder is used in a vertical standing position.

(1) Remove the caps from the 2-way and 3-way

valves.
(2) Remove the service-port cap from the 3-way valve.
(3) To open the 2-way valve turn the valve stem coun-

terclockwise approximately 90°, wait for about 2~3

sec, and close it.
(4) Apply a soap water or a liquid neutral detergent on

the indoor unit connection or outdoor unit connec-

tions by a soft brush to check for leakage of the

connecting points of the piping.
(5) If bubbles come out, the pipes have leakage.

Soap water method

3. Evacuation

• Connect the charge hose end described in the preced­ing steps to the vacuum pump to evacuate the tubing
and indoor unit.
Confirm the "Lo" knob of the manifold valve is open.
Then, run the vacuum pump.
The operation time for evacuation varies with tubing
length and capacity of the pump. The following table
shows the time required for evacuation.

• When the desired vacuum is reached, close the "Lo"
knob of the manifold valve and stop the vacuum pump.

4. Finishing the job

• With a service valve wrench, turn the valve stem of liq­uid side valve counter-clockwise to fully open the
valve.

• Turn the valve stem of gas side valve counter-clock­wise to fully open the valve.

• Loosen the charge hose connected to the gas side
service port slightly to release the pressure, then

1. Air purging (Only R-22 Model)

Required tools : hexagonal wrench, adjustable

wrench, torque wrenches, wrench to
hold the joints, and gas leak detec­tor.

The additional gas for air purging has been charged
in the outdoor unit.
However, if the flare connections have not be done
correctly and there gas leaks, a gas cylinder and the
charge set will be needed.

The air in the indoor unit and in the piping must be
purged. If air remains in the refrigeration pipes, it will
affect the compressor, reduce to cooling capacity, and
could lead to a malfunction.

• Procedure

(1) Recheck the piping connections.
(2) Open the valve stem of the 2-way valve coun-

terclockwise approximately 90°, wait 10 sec­onds, and then set it to closed position.

– Be sure to use a hexagonal wrench to operate

the valve stem.

(3) Check for gas leakage.

– Check the flare connections for gas leakage.

(4) Purge the air from the system.

– Set the 2-way valve to the open position and

remove the cap from the 3-way valve’s service
port.

– Using the hexagonal wrench to press the valve

core pin, discharge for three seconds and then
wait for one minute. Repeat this three times.

(5) Use torque wrench to tighten the service port

nut to a torque of 1.8kg.cm.

(6) Set the 3-way valve to the back seat.
(7) Mount the valve stem nuts to the 2-way and 3-

way valves.

(8) Check for gas leakage.

– At this time, especially check for gas leakage

from the 2-way and 3-way valve’s stem nuts,
and from the service port nut.

Caution

If gas leakage are discovered in step (3) above,
take the following mesures :

If the gas leaks stop when the piping connections
are tightened further, continue working from step (4).
If the gas leaks do not stop when the connections
are retightened, repair the location of the leak, dis­charge all of the gas through the service por t, and
then recharge with the specified amount of gas
from a gas cylinder.

Service port nut:
Be sure, using a torque wrench to tighten the service port nut (after using the service port), so that it prevents the
gas leakage from the refrigeration cycle.

* CAUTION : Do not leak the gas in the air during Air purging.

6. Gas Charging

(After Evacuation)

• Procedure

(1) Connect the charge hose to the charging

cylinder.

– Connect the charge hose which you dis-con-

nected from the vacuum pump to the valve at
the bottom of the cylinder.

– If you are using a gas cylinder, also use a scale

and revers the cylinder so that the system can
be charged with liquid.

(2) Purge the air from the charge hose.

– Open the valve at the bottom of the cylinder

and press the check valve on the charge set to
purge the air. (Be careful of the liquid refriger­ant). The procedure is the same if using a gas
cylinder.

(3) Open the valve (Lo side on the charge set and

charge the system with liquid refrigerant.

– If the system can not be charged with the spec-

ified amount of refrigerant, it can be charged
with a little at a time (approximately 150g each
time) while operating the air conditioner in the
cooling cycle; however, one time is not suffi­cient, wait approximately 1 minute and then
repeat the procedure (pumping down-pin).

(4) Immediately disconnect the charge hose from

the 3-way valve’s service port.

–

Stopping partway will allow the gas to be dis­charged.

–

If the system has been charged with liquid refriger­ant while operating the air conditioner turn off the air
conditioner before disconnecting the hose.

(5) Mount the valve stem nuts and the service

port nut.

– Use torque wrench to tighten the service port

nut to a torque of 1.8 kg.m.

– Be sure to check for gas leakage.

CAUTION

This is different from previous procedures.
Because you are charging with liquid refrigerant
from the gas side, absolutely do not attempt to
charge with larger amounts of liquid refrigerant
while operating the air conditioner.

CAUTION

This unit is charged with R-410A.
Pay attention not to charge R-22.
