Preface

Preface

This SERVICE MANUAL provides various service information, including the mechanical and electrical parts
etc. This room air conditioner was manufactured and assembled under a strict quality control system.
The refrigerant is charged at the factory. Be sure to read the safety precautions prior to servicing the unit.

Electronic Type

1. Unplug the power cord and connect a jumper between 2 pins (black and white).

2. The grounding conductor (green or green and yellow) is to be open.

3. Measure the resistance value with an ohm meter between the jumpered lead and each exposed metallic part on
the equipment at all Mode [except POWER OFF].

4. The value should be over 1MΩ.

Mechanical Type

1. Unplug the power cord and connect a jumper between 2 pins (black and white).

2. The grounding conductor (green) is to be open.

3. Measure the resistance value with an ohm meter between the jumpered lead and each exposed
metallic part on the equipment at all the positions (except OFF) of the ROTARY SWITCH.

4. The value should be over 1MΩ.

NOTES

— Replacement of the refrigerant.

1. When replacing the refrigerant, be sure to
Discharge the refrigerant system using a Freon
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 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.

CAUTION

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.

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.

TM

Disassembly Instructins

3. Remove the capillary tube.

4. Re-install the components by referring to notes.

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.

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.

Installation

Figure 19

CHECKING INSTALLATION

The setting conditions must be checked prior to ini­tial starting.

The items mentioned below 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.

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 DRAIN

(When using drain pipe)

The air conditioner must be installed horizontally or
tilted slightly to the outside for proper water

On exceptionally hot and humid days the air condi­tioner may overflow condensed water.

If the air conditioner is used in hot and a high
humidity zone, exchange the DRAIN CAP for the

INSTALLATION KITS CONTENTS

For installation in a casement window, the window
frame assembly and the side of the building must be
adequate to support the weight of the air conditioner.

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

8. Slide Curtain into Curtain Frame. Slide Curtain Frame
assembly into side Guides of the Air Conditioner cabi­net. 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 pro­tective 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 cab­inet 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 win­dow 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.

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 win­dow. 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.
