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

1.2 INSULATION RESISTANCE TEST

1. When servicing the unit, set the ROTARY SWITCH
or POWER SWITCH to OFF(O) 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. Unplug the power cord and connect a jumper
between 2 pins (black and white).
2. The grounding conductor (green or green & yellow)
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 or O) of the ROTARY SWITCH or
POWER SWITCH.
4. The value should be over 1MΩ.

• Designed for cooling only.

• Built in adjustable THERMISTOR and THERMOSTAT.

• Powerful and quiet cooling.
• Top-down chassis for the simple installation and service.

• Washable one-touch filter.
• Compact size.

1.5 CONTROL LOCATIONS
• OPERATION
Off
Fan Only
Low Cool
High Cool
Low Heat
High Heat

- Turns the air conditioner off.
- The low fan speed operation without cooling (heating).
- Cooling with the low speed fan operation.
- Cooling with the high speed fan operation.
- Heating with the low speed fan operation.
- Heating with the high speed fan operation.

Turn the Temperature Knob to the desired setting. The central position is a normal
setting for average conditions. You can change this setting, if necessary, in
accordance with your temperature preference.
The thermostat automatically controls cooling or heating, but the fan runs
continuously whenever the air conditioner is in operation. If the room is too warm,
turn the thermostat control clockwise. If the room is too cool, turn the thermostat
control counterclockwise.

CAUTION
A slight burning odor may come from the unit
when first switching to HEAT after the cooling
season is over. This odor, caused by fine dust
particles on the heater, will disappear quickly.
This is normal operation.

When the air conditioner has been operating in the
cooling or heating mode and is turned off or set to the fan
only position, wait at least 3 minutes before resetting to
the cooling operation again.

• VENTILATION
Push the lever to the "CLOSE" position to cool, heat or recirculate room air only.
Pull the lever to the "OPEN" position to exhaust smoke or stale air from the room.
This feature is best used in conjunction with the FAN ONLY position.

NOTES
— Replacement of the refrigeration cycle.
1. When replacing the refrigeration cycle, be sure to
discharge the refrigerant system using a FreonTM
recovery System.
Install a valve for the recovery before venting the
Freon. Remove the valve when finished.
2. After discharging the unit completely, remove the
desired component, and unbrace 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 Fig.
18A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns
counterclockwise and leave the valves closed.
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 Fig. 18B.
Open valve C.
Discharge the line at the manifold connection.
5) The system is now ready for final charging.

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 Fig. 18B.
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 Lowside.
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.
