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, turn off the air conditioner 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.

4.The value should be over 1MΩ .

1.4 FEATURES

• Designed for cooling only.

• Built in adjustable THERMOSTAT.

• Powerful and quiet.

• Washable one-touchfilter.

• Slide out chassis for the simple installation and service.

• Compact size.

1.5 CONTROL LOCATIONS

1.5.1 COOLING ONLY MODEL

• OPERATION

• 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.

CAUTION

When the air conditioner has been operating in the

PULL OPEN / PUSH CLOSE

cooling and is turned off or set to the fan only position,

 

wait at least 3 minutes before resetting to the cooling

 

operation again.

2. DISASSEMBLY INSTRUCTIONS

Prior to disassembling the unit, make sure that the POWER is off and the power cord is unplugged from the wall receptacle.

2.1 MECHANICAL PARTS

2.1.1 FRONT GRILLE

1. Open the inlet grille downward.

2. Remove the screw which fastens the front grille.

3. Pull the front grille from the right side.

4. Remove the front grille. (See Fig. 1)

5.Re-installthe component by referring to the removal procedure.

Figure 1

2.1.2 CABINET

1.After disassembling the FRONT GRILLE, remove the 6 screws which fasten the cabinet at the both sides and the top. (See Fig. 2)

Keep these for later use.

2.1.3 CONTROL BOX

1.Remove the front grille. (Refer to section 2.1.1)

2.Remove the screw which fasten the control box. (See Fig. 3)

3.Pull the control box from the barrier.(See Fig.3)

4.Discharge the capacitor by placing a 20,000 ohm resistor across the capacitor terminals.

5.Disconnect two wire housings in the control box.

6.Pull the control box forward completely.

NOTES

Replacement of the refrigeration cycle.

1.When replacing refrigeration components, 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 unbraze the pinch-offtubes.

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

4.Solder the pinch-offtubes with Service valves.

5.Evacuate as follows.

1)Connect the vacuum pump, as illustrated Fig. 17A.

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. 17B. 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. 17B. 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, and the high-sidewill 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-sidegauge; allow pressure to rise to 39 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-offtool with the unit still running and clamp on to thepinch-offtube. Using a tube cutter, cut thepinch-offtube about 2 inches from thepinch-offtool. Usesil-fossolder and solderpinch-offtube closed. Turn off the unit, allow it to set for a while, and then test for leakage add thepinch-offconnection.
