Installation  
Installation  
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  
11" 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 effi-  
ciency of the air conditioner.  
ABOUT 1/4  
"
CAUTION: All side louvers of the cabinet must  
remain exposed on the outdside of the structure.  
Over 20"  
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.  
Figure 1  
5. Install the unit with the bottom about 30"~60" above the  
floor level.  
Installation Check  
The setting conditions must be checked prior to initial starting.  
The following items are especially important checking points when the installation is finished.  
1. Grounding wire (Green or Green and Yellow) is provided in the power cord. The green wire must be grounded.  
2. Connect to a single-outlet 15A circuit.  
(or 20A circuit for Electric Heater Model)  
3. To avoid vibration or noise, make sure the air conditioner is installed securely.  
4 Avoid placing furniture or draperies in front of the air inlet and outlet.  
How to Secure the Drain Pipe  
In humid weather, excess water may cause the Base Pan to  
overflow. To drain the water, remove the Drain Cap and secure  
the Drain Pipe to the rear hole of the Base Pan. (Figure. 2)

Window Requirements  
NOTICE  
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 15" from the bottom of the  
sash to the window stool.  
OUTER  
SILL  
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. 4. Top of wood strip should be  
approximately 3/4" higher than the storm window frame  
(STORM WINDOW FRAME) or wood strip (OUT-  
DOORS) to help condensation to drain properly to the  
outside.

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  
37B. Open valve C.  
Discharge the line at the manifold connection.

TM  
6. Recharge as follows :  
servicing the system.  
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 figure  
33B.  
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, the high-side will not  
take it. Close valve A.  
2. After discharging the unit completely, remove the  
desired component, 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. Evacuate as follows.  
1) Connect the vacuum pump, as illustrated figure  
33A.  
2) Start the vacuum pump, slowly open manifold  
valves A and B with two full turns counterclock-  
wise and leave the valves open.  
The vacuum pump is now pulling through valves  
A and B up to valve C by means of the manifold  
and entire system.  
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 pressure to drop.  
d. Repeat steps b. and c. until the balance of the  
charge is in the system.  
CAUTION: If high vacuum equip-  
ment 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) When satisfied the unit is operating correctly,  
use the pinch-off tool with the unit still running  
and clamp on to the pinch-off tube. Using a tube  
cutter, cut the pinch-off tube about 2 inches from  
the pinch-off tool. Use sil-fos braze and braze  
pinch-off tube closed. Turn off the unit, allow it to  
set for a while, and then test the leakage of the  
pinch-off connection.  
3) Operate the vacuum pump vaccum 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 pres-  
sure would indicate a possible leak or moisture
