1. Precautions

1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.

2. Use proper parts: Use only exact
replacement parts. (Also, we recommend
replacing parts rather than repairing them.)

3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
equipment may cause problems later­intermittent contact, for example.

4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.

6. After completing repairs and reassembly,
check the insulation resistance.
Procedure: Prior to applying power, measure
the resistance between the power cord and the
ground terminal. The resistance must be
greater than 30 megaohms.

Fig. 1-1 Avoid Dangerous Contact

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions
are satisfactory.
Relocate the unit if necessary.

9. Keep children away from the unit while it is
being repaired.

10. Be sure to clean the unit and its surrounding
area.

3. Installation and Operating Instructions

3-1 Installation

3-1-1 Selecting Area for Installation

1. Make sure that you install the unit in an area
providing good ventilation. The air conditioner
must not be blocked by any obstacle affecting the
air flow near the air inlet and air outlet.

2. Make sure that you install the unit in an area that
allow good air handling. The installation area
must be able to endure vibration from the unit.

3. Make sure that you install the unit away from
heat or vapor.

4. Make sure that you install the unit in an area
which is cool and has adequate space.

5. Make sure that you install the unit in an area
away from TVs, audio units, cordless phones,
fluorescent lighting fixtures and other electrical
appliances (obtain a clearance of at least one
meter).

6. Make sure that you install the unit in an area
which provides easy drainage for condensed
water.

7. Make sure that you install the unit in an area not
exposed to rain or direct sunlight.
(Install a separate sunblind if exposed to direct

sunlight.)

8. Make sure that you install the unit in an area
allowing good air movement. Do not install it in
a space that would cause noise amplification of
noise.

9. Fix the unit firmly if mounted in a high place.

Caution:

Do not use the air conditioner in the following environments : greasy areas (including areas near
machines), or marine areas. Contact your local dealer for advice.

3-2-1 Thermostat

Temperature control dial

Operating mode selection dial

Selector

OFF :
When the room temperature is lowered by the
air conditioner , the gas within the thermostat
will contract and cause a break in the electric
contact. The compressor will then stop.
After the compr essor stops, the room
temperature will rise

ON :
As the room temperature increases to a
selected level, the gas within the thermostat
expands, causing electric contact, which
provides the source of electric power to the
compressor. The room temperature will fall
and the cycle will repeat.

Control Operation :
By turning the contr ol knob clockwise(toward
higher numbers), the temperatures will be cooler.
By turning the contr ol knob counterclockwise
(toward lower numbers), the temperature will be
warmer.
Level 1 : Cool air will be supplied above 30~35°C

Level 1 : Cool air will be ceased below 28~32.5°C

Level 1 :

Level 10 : Cool air will be supplied above 17.4~20.4°C

Level 10 : Cool air will be ceased below 14.4~17.4°C

Level 10 :

3-2-2 Operation

The fan selector switch offers high and low fan cooling contr ol levels to assure maximum comfort.
The two fan speeds allow you to economically circulate room air flow on days when intense cooling is
not required. When combined with the thermostat(set to call for conditioned air), these contr ols cool,
dehumidify , filter, and circulate room air, with the fan continuing to cir culate air even when the
compressor is turned off.

1. Change the compressor - DO NOT recharge the oil as the compressor itself is already charged.

2. Change the condenser .... add 50cc

3. Change the evaporator .... add 50cc

4. When the refrigerant is replaced .... add 30cc oil.

5. After vacuum is completed, the oil is filled through the high pressure side.

6. In the event of a refrigerant leak, generally it is not necessary to add oil.
(Unless the oil has leaked significantly.)
