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.

The compressor is turned off when "ambient temperature = set temperature

*

The compressor is turned on when "ambient temperature = set temperature +1˚C"

*

2) Default value after power reset ➔ set temperature = 75˚F

Fan speed = High

3) Set temperature indicating (setting) range : 1˚F interval from 64˚F to 86˚F.

*

time only, and operation that energy saver by turn off the fixation time only, and operation that energy saver
by turn off the motor continuously before the condition of the compressor on.
The fan motor is not operated at flow wind operation.

*

Energy saver operation specification at the cooling operation.

*

1) Fan motor control in compressor on : operate with setting wind speed

2) Fan motor control in compressor off : After compressor off, the fan motor is operated breeze for 2 minutes
and then it turn 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.)
