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 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 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 21A.
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-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
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 fig-
ure 21B. 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 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. Turn off the unit,
allow setting for a while and then test the leakage 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 is
installed 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 slightly 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 INSTALL
3.2.1 WINDOW REQUIREMENTS
NOTE: All supporting parts should be secured to firm
wood, masonry, or metal.
1. This unit is designed for installation in standard double 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 bottom 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. 24. Top of wood
st
rip should be approximately 3/4" higher than the
storm 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 center of the outer sill flush against the back off the inner
sill. This will raise the L bracket as shown Figure. 24.
4. If the distance between STORM WINDOW FRAME
and
WOOD STRIP MOUNTED ON TOP OF INNER
SILL is more than 1", t
wo of wood strip are not neces-
sary.
