Installation Parts Provided

1) Select the best location

1. Indoor unit

■ Do not have any heat or steam near the unit.

■ Select a place where there are no obstacles in front

of the unit.

■ Make sure that condensation drainage can be con­veniently routed away.

■ Do not install near a doorway.

■ Ensure that the space around the left and right of

the unit is more than 30cm(12"). The unit should be
installed as high on the wall as possible, allowing a
minimum of 12cm(4.8") 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(4"). The front of the unit should have more than
70cm(28") 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.

■

Select a place so that the warm air and noise from the air con­ditioner do not disturb neighbors.

■ Rooftop Installations:

If the outdoor unit is installed on a roof structure, be
sure to level the unit. Ensure the roof structure and
anchoring method are adequate for the unit location.
Consult local codes regarding rooftop mounting.
If the outdoor unit is installed on root structures or walls,
this may result in excessive noise and vibration, and
maybe also classed as non serviceable installation.

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.

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

1. Cut the pipes and the cable.

■ Use the piping kit accessory or the pipes
purchased locally.

■ Measure the distance between the indoor and the
outdoor unit.

■ Cut the pipes a little longer than measured
distance.

■ Cut the cable 1.5m(59.1") longer than the pipe
length.

2. Burrs 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. 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.

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 counter­clockwise to fully open the valve.

■ Loosen the charge hose connected to the gas
side service port slightly to release the pressure,
then remove the hose.

■ Replace the flare nut and its bonnet on the gas
side service port and fasten the flare nut securely
with an adjustable wrench. This process is very
important to prevent leakage from the system.

■ Replace the valve caps at both gas and liquid
side service valves and fasten them tight.
This completes air purging with a vacuum pump.
The air conditioner is now ready to test run.

(1) Remove the caps from the gas side and liquid side valves.
(2) Remove the service-port cap from the gas side valve.
(3) To open the gas side valve turn the valve stem counter-

clockwise 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 connections by a
soft brush to check for leakage of the connecting points of
the piping.

(5) If bubbles come out, the pipes have leakage.

5. TEST RUNNING

1. Check that all tubing and wiring have been prop­erly connected.

2. Check that the gas and liquid side service valves
are fully open.

1. Prepare remote control

Remove the battery cover
by pulling it according to the
arrow direction.

Insert new batteries making
sure that the (+) and (–) of
battery are installed correctly.

Reattach the cover by
pushing it back into position.

NOTE:

• Use 2 AAA(1.5volt) batteries. Do not use

rechargeable batteries.

• Remove the batteries from the remote control if

the system is not going to be used for a long time.

2. Settlement of outdoor unit

■ Anchor the outdoor unit with a bolt and
nut(ø10mm) tightly and horizontally on a concrete
or rigid mount.

■

When installing on the wall, roof or rooftop, anchor
the mounting base securely with a nail or wire
assuming the influence of wind and earthquake.

■

In the case when the vibration of the unit is con­veyed to the hose, secure the unit with an
anti-vibration rubber.

3. Evaluation of the performance

Operate unit for 15~20 minutes, then check the sys­tem refrigerant charge:

1. Measure the pressure of the gas side service
valve.

2. Measure the temperature of the intake and dis­charge of air.

NOTE: If the actual pressure are higher than shown,

the system is most likely over-charged, and
charge should be removed. If the actual pres­sure are lower than shown, the system is most
likely undercharged, and charge should be
added.
The air conditioner is now ready for use.

2. Open the gas side service valve halfway and purge the
air from the manifold hose using the refrigerant gas.

3. Close the liquid side service valve(all the way in).

4. Turn on the unit's operating switch and start the cool­ing operation.

5. When the low-pressure gauge reading becomes 1 to

0.5kg/cm2G(14.2 to 7.1 P.S.I.G.), fully close the gas
side valve stem and then quickly turn off the unit. At
that time, Pump Down has been completed and all
refrigerant gas will have been collected in the outdoor
unit.

2) Balance refrigerant of the 3-way valve

(Gas leakage)

• Procedure

(1) Confirm that both the liquid side and gas side

valves are set to the back seat.

(2) Connect the charge set to the 3-way valve’s

port.

– Leave the valve on the charge set closed.
– Connect the charge hose to the service port.

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

discharge the refrigerant until the gauge indi­cates 0 kg/cm2G.

– If there is no air in the refrigerant cycle (the

pressure when the air conditioner is not running
is higher than 1 kg/cm2G), discharge the refrig­erant until the gauge indicates 0.5 to 1
kg/cm2G. if this is the case, it will not be neces­sary to apply a evacuatin.

– Discharge the refrigerant gradually; if it is dis-

charged too suddenly, the refrigeration oil will
also be discharged.

2. Evacuation

(All amount of refrigerant leaked)

• Procedure

(1) Connect the vacuum pump to the center hose

of charge set center hose

(2) Evacuation for approximately one hour.

– Confirm that the gauge needle has moved

toward -76 cmHg (vacuum of 4 mmHg or less).

(3) Close the valve (Lo side) on the charge set,

turn off the vacuum pump, and confirm that
the gauge needle does not move (approxima­tely 5 minutes after turning off the vacuum
pump).

(4) Disconnect the charge hose from the vacuum

pump.

– Vacuum pump oil.

If the vacuum pump oil becomes dirty or
depleted, replenish as needed.

3. 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 reverse 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 dis-

charged.

– 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.

\

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.

Cycle Troubleshooting Guide

Trouble analysis

1. Check temperature difference between intake and discharge air and operating current.

Temp. Difference

Temp. difference : approx. 0°C
Current : less than 80% of

rated current

Temp. difference : approx. 8°C(14°F)
Current : less than 80% of

rated current

Temp. difference : less than 8°C(14°F)
Current : over the reated

current

Temp. difference : over 8°C(14°F)

Operating Current

• All amount of refrigerant leaked
out. Check refrigeration cycle.

• Refrigerant leakege

Clog of refrigeration cycle
Defective compressor

• Excessive amount of refrigerant

• Normal

Notice :

Temperature difference between intake and discharge air depends on room air humidity. When the room air
humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower tem­perature difference is larger.

2. Check temperature and pressure of refrigeration cycle.

Notice :

1. The suction pressure is usually 4.5~6.0 kg/cm2G(Cooling) at normal condition.

2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with
putty.
