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 sunlight does not shine directly  
on the unit.  
FENCE  
AWNING  
3.The outside of the cabinet must extend outward for at  
least 30cm and there should be no obstacles, such as a  
fence or wall, within 50cm 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.  
COOLED AIR

RADIATION  
ABOUT 10~15mm  
Over 50cm  
CAUTION: All side louvers of the cabinet  
must remain exposed to the outside of  
the structure.  
Figure 1  
4.Install the unit a little slanted so the back is slightly lower  
than the front (about 10~15mm). This will help force con-  
densed water to the outside.  
5.Install the unit from the bottom about 75~150cm 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. Press the drain pipe into the hole by pushing down and away from  
Drain pipe  
the fins to avoid injury.  
Drain cap  
Optional  
CABINET  
SCREW  
1. Install the drain pan over the corner of the cabinet where you removed the  
plug with 4 (or 2) screws.  
2. Connect the drain hose to the outlet located at the bottom of the drain pan.  
You can purchase the drain hose or tubing locally to satisfy your particular  
needs. (Drain hose is not supplied).  
3. Select the most appropriate connection from among the following figures (by  
considering the hole of the unit) to fit drain pan to your own unit.

the Freon . Leave the valve in place after  
servicing the system.  
2. After discharging the unit completely, remove the  
desired component, and unbraze the pinch-off  
tubes.  
With valve C open, discharge the hose at the mani-  
fold connection.  
3. Braze service valves into the pinch-off tube ports,  
leaving the valves open.  
4. Braze the pinch-off tubes with Service valves.  
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.  
5. Evacuate as follows.  
1) Connect the vacuum pump, as illustrated figure  
33A.  
5) With the unit running, open valve B and add the  
balance of the charge.  
2) Start the vacuum pump, slowly open manifold  
valves A and B with two full turns counterclockwise  
and leave the valves open.  
a. Do not add the liquid refrigerant to the Low-  
side.  
b. Watch the Low-side gauge; allow pressure to  
rise to 30 lbs (0.2Mp).  
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.  
The vacuum pump is now pulling through valves  
A and B up to valve C by means of the manifold  
and entire 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 counterclockwise.  
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 brazing rod 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 pressure would indi-  
cate a possible leak or moisture remaining in the  
system. With valves A and B closed, stop the vac-  
uum pump.  
4) Remove the hose from the vacuum pump and  
place it on the charging cylinder. See figure 33B.  
Open valve C.  
Discharge the line at the manifold connection.  
5) The system is now ready for final charging.
