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 wire insulation.

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.

—2—

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 .

CAUTION

If high vacuum equipment is used, adjust valves A and B so they are opened only slightly 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 vaccum 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 18B, on page 11.

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 theHigh-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 18B, on page 11.

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 must remain closed.

4)If more charge is required, 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 30 lbs.

c.Turn off valve B and allow pressure to drop.

d.Repeat steps b. and c. until the balance of the is in the system.

6)When satisfied that 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" from the top of thepinch-offtool. Usesil-fossolder and solderpinch-offtube closed. Turn off the unit, allow it to set for a while, and then test the leakage of thepinch-offconnection.

3. INSTALLATION

3.1 HOW TO INSTALL THE UNIT

1.To avoid 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.

If the unit receives direct sunlight, build an awning to shade the cabinet.

3.There should be no obstacle, like a fence, within 20" which might restrict heat radiation from the condenser.

4.To prevent reducing performance, install the unit so that louvers of the cabinet are not blocked.

5.Install the unit with a slight downward slope towards the outside (about 1/4"), to ensure that all condensate drains outside.

6.Install the unit with its bottom portion 30~60" above the interior floor level.

7.Stuff the foam gasket between the top of the unit and the wall to prevent air and insects from getting into the room.

8.The power cord must be connected to an independent circuit. The green wire must be grounded.

9.Connect the drain tube to the base pan hole in the rear side if you need to run a drain hose.(consult a dealer). Plastic hose or equivalent may be connected to the drain tube.

3.2 CHECKING INSTALLATION

The setting conditions must be checked prior to initial start up.

The items mentioned below are important check points to review when the installation is complete.

1.A grounding wire (Green or Green and Yellow) is provided in the power cord. The green wire must be grounded.

2.Connect to a single-outlet15A circuit.

3.To avoid vibration or noise, make sure the air conditioner is securely installed.

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 with a slight tilt towards the outside for proper water drainage.

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

If the air conditioner is used in a high humidity zone, exchange the DRAIN CAP for theDRAIN PIPE.(See Figure 20, Figure 21)

8.Slide curtain into curtain frame. Slide curtain frame assembly into side guides of the air conditioner cabinet. Make sure curtain is firmly enclosed on all sides by the frame. (See Figure 27)

9.Cut side guide seal into 2 equal lengths. Remove protective backing and apply it to the rear side of cabinet side guides, starting just below curtain frame assembly. Pinch off excess length so seal is even with the bottom of side guide. (See Figure 28)

10.Place air conditioner in window opening. It should sit on bracket assembly so that curtain frame and cabinet side guides are against top and side window jambs. Mate front of bracket with base guide attached to the bottom of base pan.

11.Drill 1/8 inch holes in window track through the existing holes on base guide. Screw 4-typeC screws through the holes. (See Figure 29)

12.If this is a casement window installation, proceed to casement window installation. If not, slide inner window sash firmly against side of the cabinet.

13.Drill 1/8 inch hole in window jamb to align with the existing holes in the curtain frame. Attach curtain frame to window frame with 2-typeB screws. (See Figure 29)

NOTE: Check all seals and plug any remaining air gaps with a suitable weatherproof caulk.

14.If this is a casement window installation, proceed to casement window installation. If not, stuff the foam seal strip between the vertical sash and the window glass. (See Figure 30)

15.Attach the window locking bracket with a type B screw. (See Figure 30)

3.7CASEMENT WINDOW INSTALLATION

Installation procedure is the same as that described in steps 1 through 11 and step 13 of the horizontal sliding window installation.

If the window opening is wider than 15-3/4"you will need to install a filler panel. Make this panel from 3/4 inch thick wood and run it the full length of the window. Attach it securely to the window frame and paint it to protect it from the weather.

Since styles and sizes of casement windows vary widely, it is advisable to have the air conditioner installed by someone skilled in this type of installation.

4.3 TROUBLESHOOTING GUIDE

In general, possible trouble is classified in two kinds.

The one is called Starting Failure which is caused from an electrical defect, and the other is ineffective Air Conditioning caused by a defect in the refrigeration circuit and/or improper application.

Unit runs but poor cooling.

Ineffective Cooling

Check cold air circulation for smooth flow.

Dirty indoor coil (Heat exchanger)

Malfunction of fan

Clogged air filter

Obstruction at air outlet

Correct above problem

Check clogging in refrigeration system.

Repair clogging in refrigeration system.

Check outdoor coil

(heat exchanger) & the fan operation.

Check for gas leakage.

Repair gas leak.

Replace unit if the unit is beyond repair.

Satisfactory operation with temperature difference of inlet & outlet air ;

44~50° F(7~10° C)

Check heat load increase.
