1. PREFACE

This

SERVICE MANUAL provides various service information, including the mechanical and electrical

parts etc. This room air conditioner was manufactured and assembled under a strict quality control system.
The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.

1.1 SAFETY PRECAUTIONS

1. When servicing the unit, set the ROTARY SWITCH
or POWER SWITCH to OFF and unplug the power
cord.

2. Observe the original lead dress.
If a short circuit is found, replace all parts which
have been overheated or damaged by the short
circuit.

3. After servicing the unit, make an insulation resis­tance test to protect the customer from being
exposed to shock hazards.

1.2

INSULATION RESISTANCE TEST

1. Unplug the power cord and connect a jumper
between 2 pins (black and white).

2. The grounding conductor (green) is to be open.

3. Measure the resistance value with an ohm meter
between the jumpered lead and each exposed
metallic part on the equipment at all the positions
(except OFF) of the ROTARY SWITCH.

4. The value should be over 1MΩ.

2.4.3 CAPILLARY TUBE

1. Remove the cabinet. (Refer to section 2.1.2)

2. After discharging the refrigerant completely,
unbraze the interconnecting tube at the capillary
tube.(See caution above)

NOTES

— Replacement of the refrigeration cycle.

1. When replacing the refrigeration cycle, be sure to
Discharge the refrigerant system using a Freon
recovery System.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the FreonTM. Leave the valve in place after
servicing the system.

2. After discharging the unit completely, remove the
desired component, and unbraze the pinch-off
tubes.

3. Solder service valves into the pinch-off tube ports,
leaving the valves open.

4. Solder the pinch-off tubes with Service valves.

5. Evacuate as follows.

1) Connect the vacuum pump, as illustrated figure

16A.

2) Start the vacuum pump, slowly open manifold

valves A and B with two full turns
counterclockwise and leave the valves open.
The vacuum pump is now pulling through valves
A and B up to valve C by means of the manifold

and entire system.

CAUTION

If high vacuum equipment is used, just crack
valves A and B for a few minutes, then open
slowly with the two full turns counterclockwise.
This will keep oil from foaming and being
drawn into the vacuum pump.

3) Operate the vacuum pump for 20 to 30 minutes,

until 600 microns of vacuum is obtained. Close
valves A and B, and observe vacuum gauge for
a few minutes. A rise in pressure would
indicate a possible leak or moisture remaining in
the system. With valves A and B closed, stop

the vacuum pump.

4) Remove the hose from the vacuum pump and

place it on the charging cylinder. See figure
16B.
Open valve C.
Discharge the line at the manifold connection.

5) The system is now ready for final charging.

TM

3. Remove the capillary tube.

4. Re-install the components by referring to notes.

6. Recharge as follows :

1) Refrigeration cycle systems are charged from
the High-side. If the total charge cannot be put
in the High-side, the balance will be put in the
suction line through the access valve which you
installed as the system was opened.

2) Connect the charging cylinder as shown in figure
16B.
With valve C open, discharge the hose at the
manifold connection.

3) Open valve A and allow the proper charge to
enter the system. Valve B is still closed.

4) If more charge is required, the high-side will not
take it. Close valve A.

5) With the unit running, open valve B and add the
balance of the charge.

a. Do not add the liquid refrigerant to the Low-

side.

b. Watch the Low-side gauge; allow pressure to

rise to 30 lbs.
c. Turn off valve B and allow pressure to drop.
d. Repeat steps b. and c. until the balance of the

charge is in the system.

6) When satisfied the unit is operating correctly,
use the pinch-off tool with the unit still running
and clamp on to the pinch-off tube. Using a tube
cutter, cut the pinch-off tube about 2 inches from
the pinch-off tool. Use sil-fos solder and solder
pinch-off tube closed. Turn off the unit, allow it to
set for a while, and then test the leakage of the
pinch-off connection.

3. INSTALLATION

3.1 SELECT THE BEST LOCATION

1.To prevent vibration and noise, make sure the unit
is installed securely and firmly.

2.Install the unit where the sunlight does not shine
directly on the unit.

3.The outside of the cabinet must extend outward for
at least 12" and there should be no obstacles, such
as a fence or wall, within 20" from the back of the
cabinet because it will prevent heat radiation of the
condenser.
Restriction of outside air will greatly reduce the
cooling efficiency of the air conditioner.

CAUTION

All side louvers of the cabinet must remain
exposed to the outside of the structure.

4.Install the unit a little slanted so the back is slightly
lower than the front (about 1/2"). This will help force
con-densed water to the outside.

5.Install the unit from the bottom about 30"~60"
above the floor level.

3.2 CHECK OF INSTALLATION

The setting conditions must be checked prior to
initial starting.

The undermentioned items are especially important
checking points when the installation is finished.

1. Grounding wire (Green or Green and Yellow) is

provided in the power cord. The green wire must
be grounded.

2. Connect to a single-outlet 15A circuit.

(or 20A circuit for Electric Heater Model)

3. To avoid vibration or noise, make sure the air

conditioner is installed securely.

4 Avoid placing furniture or draperies in front of the

air inlet and outlet.

3.3. HOW TO DRAIN
(When using drain pipe)

The air conditioner must be installed horizontally or
tilted slightly to the outside for proper water
drainage.

On exceptionally hot and humid days the air
conditioner may overflow condensed water.

If the air conditioner is used in hot and a high
humidity zone, exchange the HOLE RUBBER
for the DRAIN PIPE.(See figure 18, figure 19.)

PREPARATION OF CHASSIS

1. Remove the screws which fasten the cabinet at
both sides and at the back.

2. Slide the unit out from the cabinet by gripping the
base pan handle and pulling forward while
bracing the cabinet.

3. Cut the window sash seal to the proper length. Peel
off the backing and attach the Foam-Pe to the
underside of the window sash.

4. Remove the backing from the top upper guide

5. Attach the upper guide onto the top of the cabinet
with 3 type A screws.

6. Insert the Frame Guides into the bottom of the
cabinet.

7. Insert the Frame Curtain into the upper guide
and Frame Guides .

8. Fasten the curtains to the unit with 4 Type A screws
at the both sides.

CABINET INSTALLATION

1. Open the window. Mark a line on center of the

window stool (or desired air conditioner location).
Carefully place the cabinet on the window stool and
align the center mark on the front angle with the
center line marked in the window stool.

2. Pull the bottom window sash down behind the

upper guide until it meets.
