—Replacement of the refrigerant.
1. When replacing the refrigerant, be sure to
Discharge the refrigerant system using a FreonTM
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. 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
18A.
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.
3) Operate the vacuum pump 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
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
18B.
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
18B.
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, adjust valves
A and B so they are opened only slightly 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.
CAPILLARY TUBE
1. Remove the cabinet. (Refer to section 2.1.2)
2. After discharging the refrigerant completely,
unbraze the interconnecting tube at the capillary
tube.(See caution above)
3. Remove the capillary tube.
4. Re-install the components by referring to notes.

Installation
HOW TO INSTALL THE UNIT
1. To avoid 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.
If the unit receives direct sunlight, build an awning to
shade the cabinet.
3. There should be no obstacle, like a fence, within 20"
which might restrict heat radiation from the condenser.
4. To prevent reducing performance, install the unit so that
louvers of the cabinet are not blocked.
5. Install the unit a little obliquely outward not to leak the
condensed water into the room (about 1/4").
6. Install the unit with its bottom portion 30~60" above the
floor level.
7. Stuff the foam between the top of the unit and the wall to
prevent air and insects from getting into the room.
8. The power cord must be connected to an independent
circuit. The green wire must be grounded.
9. Connect the drain tube to the base pan hole in the rear
side if you need to drain (consult a dealer).
Plastic hose or equivalent may be connected to the drain
tube.
CHECKING INSTALLATION
The setting conditions must be checked prior to ini-
tial starting.
The items mentioned below are especially impor-
tant checking points when the installation is fin-
ished.
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.
3. To avoid vibration or noise, make sure the air con-
ditioner is installed securely.
4 Avoid placing furniture or draperies in front of the
air inlet and outlet.
HOW TO DRAIN
(When using drain pipe)
The air conditioner must be installed horizontally or
tilted slightly to the outside for proper water
drainage.
On exceptionally hot and humid days the air condi-
tioner may overflow condensed water.
If the air conditioner is used in hot and a high
humidity zone, exchange the DRAIN CAP for the

Installation
1. Loosely attach the Support Bracket to the bottom of
Bracket using Bolts, Washers, and Nuts. Attach the
Leveling bolt and nut. (See Figure 22)
2. Remove protective backing from Window Track Seal
and apply seal to window track. (See Figure 23)
3. Measure and lightly mark a line 8-1/4 inches from win-
dow jamb. Center the Support Bracket assembly on
the window track and fasten with 4 Type C screws.
(See Figure 23)
4. Put the Support Bracket against the outside wall and
tighten the Bolts on top of the Bracket. Adjust the
Leveling Bolt so that the air conditioner will be
installed with a very slight tilt (about 1/4") downward
toward the outside for proper drainage.
Tighten the nut. (See Figure 24)
NOTE: DO NOT drill a hole in the bottom of the base
pan. The air conditioner is designed to operate
with the bottom of the base pan approximately
half-full of water.
5. Fasten Side Guides to the sides of the Air Conditioner
using 3 Type A screws per Guide. Start with first
screw at middle of Guide. (See Figure 25)
6. Fasten Upper Guide on the top of the Air Conditioner
using 3 Type A screws. (See Figure 25)
7. Measure height of window opening from top of
Bracket assembly as shown Fig. 26.
Subtract 20-3/4 inches. Mark this measurement on
Curtain and cut the Curtain. (See Figure 26)

8. Slide Curtain into Curtain Frame. Slide Curtain Frame
assembly into side Guides of the Air Conditioner cabi-
net. Make sure Curtain is firmly enclosed on all sides
by the Frame. (See Figure 27)
9. Cut side Guide seal into 2 equal lengths. Remove pro-
tective backing and apply it to the rear side of cabinet
Side Guides, starting just below Curtain Frame
assembly. Pinch off excess length so seal is even with
the bottom of side Guide. (See Figure 28)
10. Place Air Conditioner in window opening. It should sit
on Bracket assembly so that Curtain Frame and cab-
inet Side Guides are against top and side window
jambs. Mate front of Bracket with Base Guide
attached to the bottom of base pan.
11. Drill 1/8 inch holes in window track through the exist-
ing holes on Base Guide. Screw 4 Type C screws
through the holes. (See Figure 29)
12. If this is a casement window installation, proceed to
Casement Window Installation. If not, slide inner win-
dow sash firmly against side of the cabinet.
13.
Drill 1/8 inch hole in window jamb to align with the
existing holes in the Curtain Frame. Attach Curtain
Frame to window frame with 2 Type B screws. (See
Figure 29)
NOTE: Check all seals and plug any remaining air gaps
with a suitable weatherproof caulk.
14. If this is a casement window installation, proceed to
Casement Window Installation. If not, stuff the Foam
Seal Strip between the vertical sash and the window
glass. (See Figure 30)
15. Attach the Window Locking Bracket with a Type B
screw.
(See Figure 30)
CASEMENT WINDOW INSTALLATION
•Installation procedure is the same as that described in
steps 1 through 11 and step 13 of the Horizontal
Sliding Window installation.
•If the window opening is wider than 15-3/4 inches you
will need to install a filler panel. Make this panel from
3/4 inch thick wood and run it the full length of the win-
dow. Attach it securely to the window frame and paint it
to protect it from the weather.
•Since styles and sizes of casement windows vary wide-
ly, it is advisable to have the air conditioner installed by
someone skilled in this type of installation.
