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
12" 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.

"
CAUTION: All side louvers of the cabinet must
remain exposed on the outdside of the structure.
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 13" 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.

NOTICE
— Replacement of the refrigeration cycle.
6. Recharge as follows :
1. When replacing the refrigeration cycle, be sure to
TM
Discharge the refrigerant system using a Freon
recovery 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
25B.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
TM
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
manifold connection.
3. Solder service valves into the pinch-off tube ports,
leaving the valves open.
4. Solder 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
25A.
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 counterclock-
wise 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.
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 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
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

Condenser air flow restric-
tion
Remove the cabinet. inspect the interior surface of
the condenser; if restricted, clean carefully with a vac-
uum cleaner (do not damage fins) or brush. Clean the
interior base before reassembling.
Condenser fins (damaged) If condenser fins are closed over a large area on the
coil surface, head pressures will increase, causing
the compressor to overload. Straighten the fins or
replace the coil.
