NOTES

Replacement of the refrigeration cycle.

1. When replacing the refrigerating cycle, be sure to

discharge the refrigerant by using a refrigerant

recovery system.

2. After discharging the unit completely, remove thedesired 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 completing 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 in

figure 20A.

6-2. Start the vacuum pump. Slowly open manifoldvalves A and B with two full turns counter-

clockwise 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-clock-

wise. This will keep oil from foaming and being

drawn into the vacuum pump.

6-3. Operate the vacuum pump for 20 to 30 min-

utes, 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 remaining 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

20B. 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 putin 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 fig-

ure 20B. 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 low-side gauge, allow pressure to

rise to 30 lbs.

c. Turn 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 still running and the

clamp on the pinch-off tube. Using a tube cut-ter, cut the pinch-off tube about 2 inches from

the pinch-off tool. Use sil-fos solder and solder

the pinch-off tube closed. Turn off the unit,

allow setting for a while and then test the leak-

age of the pinch-off connection.

3. INSTALLATION

This air conditioner is designed with a button-down

chassis so it can be easily installed in a window.

3.1 SELECT THE BEST LOCATION

1. To prevent vibration and noise, make sure the unit isinstalled securely and firmly.

2. Install the unit where the sun does not shine directly

on the unit.

3. The outside of the cabinet must extend outward for at

least 10" and there should be no obstacles, such as a

fence or wall, within 20" from the back of the cabinet

because it will prevent heat radiation of the condenser.

Restriction of outside air will greatly reduce the cooling

efficiency of the air conditioner.

4. Install the unit slanted slightly so the back is slight-

ly lower than the front (about 1/4"). This will force

condensed water to the outside.

5. Install the unit with the bottom about 30"~60"

above the floor level.

3.2 HOW TO INSTALL3.2.1 WINDOW REQUIREMENTSNOTE: All supporting parts should be secured to firm

wood, masonry, or metal.1. This unit is designed for installation in standard dou-

ble hung windows with actual opening widths of 22" to

36". The upper and lower sash must open sufficiently

to allow a clear vertical opening of 13" from the bot-

tom of the sash to the window stool.

2.If storm window presents interference, fasten a 2" wide

wood strip to the inner window sill across the full

width of the sill. The 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. 23. Top of wood

strip should be approximately3

/4" higher than thestorm window frame (STORM WINDOW FRAME) or

wood strip (OUTDOORS) to help condensation to

drain properly to the outside.

3. Install a second wood strip (approximately 6" long by

11/2" wide and same thickness as first strip) in the cen-

ter of the outer sill flush against the back off the inner

sill. This will raise the L bracket as shown Figure. 23.

4. If the distance between STORM WINDOW FRAME

and WOOD STRIP MOUNTED ON TOP OF INNER

SILL is more than 1", two of wood strip are not neces-

sary.
