1.4 SAFETY PRECAUTIONS

1. When servicing, set the ROTARY 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, make an insulation resistance test

to prevent the customer from being exposed to

shock hazards.

1.5 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 yel-

low) 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 position

[except Off ( 0 )] of the ROTARY SWITCH.

4. The value should be over 1 M_.

NOTES

Replacement of the refrigeration cycle.

1. When replacing the refrigerating cycle, be sure to discharge the refrigerant by using a refrigerant recovery sys-

tem.

2. After discharging the unit completely, remove the desired components, 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. After doing the above procedures, the valve must be closed and left in place on the system for any subsequent

procedures.

6. Evacuate as follows:

6-1. Connect the vacuum pump, as illustrated figure 72A.

6-2. 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 manifold and the 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 counter-clockwise. This will keep oil from foaming and being drawn into the vacuum

pump.

6-3. Operate the vacuum pump for 20 to 30 minutes, until 600 micron 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 remains in the system.

With valves A and B closed, stop the vacuum pump.

6-4. Remove the hose from the vacuum pump and place it on the charging cylinder. See figure 23B. Open valve C.

Discharge the line at the manifold connection.

6-5. The system is now ready for final charging.

7. Recharge as follows :

7-1. Rotary compressor 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 is installed as the system is opened.

7-2. Connect the charging cylinder as shown in figure 72B. With valve C open, discharge the hose at the manifold

connection.

7-3. Open valve A and allow the proper charge to enter the system. Valve B is still closed.

7-4. If more charge is required, the high-side will not take it. Close valve A.

7-5. 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 tow-side gauge, allow pressure to rise to 30 Ibs.

c. rum off valve B and allow the pressure to drop.

d. Repeat steps B and C until the balance of the charge is in the system.

7-6. When the unit is operating correctly, use the pinch-off tool with the unit stillrunning and the clamp on 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 the pinch-off tube closed. rum off the unit, allow setting for a while and then test the leak-

age of the pinch-off connection.

Equipment needed: Vacuum pump, charging cylinder, manifold gauge, brazing equipment, pinch-off tool capable

of making avapor proof seal, leak detector, tubing cutter, hand tools to remove components, service valve.

1. Insert the sliding panels (ITEM H) into the guides

of the air conditioner. Fasten the curtains to the

unit with screws (ITEM B), as shown in Figure 73.

2. Cut the adhesive-backed seal strip (ITEM E) to

the window width.

Remove the backing from the seal strip and attach

the seal strip to the underside of the bottom win-

dow. (See Figure 74)

4. Attach L bracket

•The units install L bracket (ITEM G) center in

back of inner window sill, with short side of

bracket to the outside. Use the 2 screws (ITEM

A) provided.

•Bracket helps to hold unit securely in place. Be

sure to place bracket edge flush against back of

inner sill. (See Figure 76)

5. INSTALL THE AIR CONDITIONER IN THE WIN-

DOW

•Carefully liftthe air conditionerand slide it into the

open window. Make sure the bottom guide of the

airconditioner dropsinto the L bracket.

•When the air conditionerdrops into the L bracket,

the air conditionerwill be centered in window

openingas shown in Figure 77.

•While steadyingthe air conditioner,carefullybdng

7. INSTALL THE SASH SEAL AND SASH LOCK

• Cut the sash seal to the window width.

Stuff the sash seal between the glass and the

window to prevent air and insects from getting

into the room, as shown in Figure 79.

• Screw the sash lock (ITEM D) on using an ITEM

•If storm window presents interference, fasten a2"

wide wood strip to inner window sill across the full

width of the sill. Wood strip should be thick enough

to raise the height of the window sill so that the

unit can be installed without interference by the

storm window frame. See Figure 80.

Top of wood stdp should be approximately 3/4"

higher than storm window frame or wood strip

(OUTDOORS) to help unit condensation to drain

propedy to the outside.

• Install a second wood strip (approximately 6" long

1" wide and same thickness as first strip) in the

center of the outer sill flush against the back of the

inner sill. This will raise the L bracket as shown in

Figure 80.

•If the distance between "STORM WINDOW

HOW TO INSTALL

1. Remove the screws which fasten the cabinet at

both sides and at the back.

2. Slide the unit out of the cabinet by gripping the

base pan handle and pull forward while bracing

the cabinet.

4. Insert the side curtain _into the upper guide and

lower guide of the air conditioner. Fasten the cur-

tains to the unit with (8) TYPE A screws _).

5. 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 angle front with

the center line marked in the window stool.

6. Pull the bottom window sash down behind the

upper guide until it meets.

NOTE: Do not pull the window sash down so tightly

that the movement of side curtain is restrict-

ed.

7. Loosely assemble the sill support using the parts

Attach the sill supports to the cabinet track hole in

relation to the selected position using TYPE A

screw @.

9. Place the sill supports with the cabinet on the win-

dow sill's selected position.

10. The cabinet should be installed with a very slight

tilt (about 1/4") downward toward the outside

(See Figure 89).

Adjust the bolts and the nuts of sill supports to

level the cabinet.

with a vacuum cleaner (do not damage fins) or

brush. Clean the interior base before

re-assembling.

Condenser fins If the condenser fins are closed over a large

(damaged) area on the coil surface, head pressures will

increase, causing the compressor to cycle.

Straighten the fins or replace the coil.
