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.

1.2

1.1 SAFETY PRECAUTIONS

1. When servicing, turn the unit 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, make an insulation resistance test to
prevent the customer from being exposed to shock
hazards.

—2—

INSULATION RESISTANCE TEST

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

2. The grounding conductor (green or green and 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 each working status.

4. The value should be over 1 MΩ.

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 Freon

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

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

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

. Remove the valve when finished.

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.

the vacuum pump.

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.

COMPLAINT CAUSE REMEDY

Fan motor will not run.

Fan motor runs
intermittently

No power

Power supply cord

Rotary switch

Wire disconnected or
connection loose

Capacitor (Discharge
capacitor before testing.)

Will not rotate

Revolves on overload.

Check voltage at outlet. Correct if none.

Check voltage to rotary switch. If none, check power
supply cord. Replace cord if circuit is open.

Check switch continuity. Refer to wiring diagram for
terminal identification. Replace switch if defective.

Connect wire. Refer to wiring diagram for terminal
identification. Repair or replace loose terminal.

Test capacitor.
Replace if not within ±10% of manufacturer's rating.
Replace if shorted, open, or damaged.

Fan blade hitting shroud or blower wheel hitting
scroll. Realign assembly.

Units using slinger ring for condenser fan must have

1

/4to 5/16inch clearance to the base. If it hits the
base, shim up the bottom of the fan motor with
mounting screw(s).

Check fan motor bearings; if motor shaft will not
rotate, replace the motor.

Check voltage. If not within limits, call an electrician.

Test capacitor.
Check bearings. Does the fan blade rotate freely?
If not, replace fan motor.

Fan motor noise.

Compressor will not run,
but fan motor runs.

Fan

Blower

Loose clamper

Worn bearings

Voltage

Wiring

Rotary

Pay attention to any change from high speed to
low speed. If the speed does not change, replace the
motor.

If cracked, out of balance, or partially missing,
replace it.

If cracked, out of balance, or partially missing,
replace it.

Tighten it.

If knocking sounds continue when running or loose,
replace the motor. If the motor hums or noise
appears to be internal while running, replace motor.

Check voltage.
If not within limits, call an electrician.

Check the wire connections, if loose, repair or
replace the terminal. If wires are off, refer to wiring
diagram for identification, and replace. Check wire
locations. If not per wiring diagram, correct.

Check for continuity, refer to the wiring diagram for
terminal identification. Replace the switch if circuit is
open.

COMPLAINT CAUSE REMEDY

Compressor will not run,
but fan motor runs.

Compressor cycles on
overload.

Compressor cycles on
overload.

Thermostat

Capacitor (Discharge
capacitor before servicing.)

Compressor

Overload

Voltage

Overload

Fan motor

Condenser air flow
restriction

Check the position of knob. If not at the coldest

setting, advance the knob to this setting and restart
unit.
Check continuity of the thermostat. Replace
thermostat if circuit is open.

Check the capacitor.
Replace if not within ±10% of manufacturers rating.
Replace if shorted, open, or damaged.

Check the compressor for open circuit or ground. If
open or grounded, replace the compressor.

Check the compressor overload, if externally
mounted. Replace if open. (If the compressor
temperature is high, remove the overload, cool it,
and retest.)

Check the voltage.
If not within limits, call an electrician.

Check overload, if externally mounted.
Replace if open. (If the compressor temperature is
high, remove the overload, cool, and retest.)

If not running, determine the cause. Replace if
required.

Remove the cabinet. inspect the interior surface of
the condenser; if restricted, clean carefully with a
vacuum cleaner (do not damage fins) or brush.
Clean the interior base before reassembling.

Compressor cycles on
overload.

Insufficient cooling or
heating

Excessive noise

Condenser fins (damaged)

Capacitor

Wiring

Refrigerating system

Air filter

Exhaust damper door

Unit undersized

Blower or fan

Copper tubing

If condenser fins are closed over a large area on the
coil surface, head pressures will increase, causing
the compressor to overload. Straighten the fins or
replace the coil.

Test capacitor.

Check the terminals. If loose, repair or replace.

Check the system for a restriction.

If restricted, clean of replace.

Close if open.

Determine if the unit is properly sized for the area to
be cooled.

Check the set screw or clamp. If loose or missing,
correct. If the blower or fan is hitting air guide,
rearrange the air handling parts.

Remove the cabinet carefully and rearrange tubing
not to contact cabinet, compressor, shroud, and
barrier.
