discharge the refrigerant system using a Freon
TM
recovery System.
If there is no valve to attach the recovery system,
install one (such as a WATCO A-1) before venting
the FreonTM. 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.
3. Braze service valves into the pinch-off tube ports,
leaving the valves open.
4. Braze the pinch-off tubes with Service valves.
5. Evacuate as follows.
1) Connect the vacuum pump, as illustrated figure
20A.
2) Start the vacuum pump, slowly open manifold
valves A and B with two full turns
counterclockwise 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.
3) Operate the vacuum pump for 20 to 30 minutes,
until 600 microns of 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.
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.
5) The system is now ready for final charging.
6. Recharge as follows :
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
20B.
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.
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.
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 solder and solder
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.
NOTES
If high vacuum equipment 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.

3. INSTALLATION
3.1 HOW TO INSTALL THE UNIT
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.
3. The outside of the cabinet must extend outward
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.
CAUTION: All side louvers of the cabinet must
remain exposed to the outside of the structure.
4. Install the unit a little slanted so the back is
slightly lower than the front (about 1/4").
This will force condensed water to flow to the
outside.
5. Install the unit with the bottom about 30"~60"
above the floor level.
3.2 CHECK OF INSTALLATION
The setting conditions must be checked prior to
initial starting.
The undermentioned 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 21A 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.
3.3 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
from 26" to 39 3/8".

• If storm window presents interference, fasten a
2"(51mm) 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 unit can be installed without
interference from the the storm window frame. See
Figure 30.
Top of wood strip should be approximately
3/4"(19mm) higher than the storm window frame to
help condensation to drain properly to the outside.
• Install a second wood strip (approximately
6"(152mm) long by 11/2"(38mm) wide and same
thickness as first strip) in the center of the outer sill
flush against the back of the inner sill. (Figure 30)
