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 megohms.
Fig. 1-1 Avoid Dangerous Contact
Fig. 1-2 No Tapping and No Extension Cords
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
When selecting the area for installing the unit, be sure to obtain approval of the customer.
*
1. Make sure that you install the unit in an area that
provides 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 which
can endure the weight and vibration of 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 where
the cooled air can be evenly spread in a room.
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 sun-
light.)
8. Do not install the unit in an area subjected to noise
or vibration amplification which may affect your
neighbor.
(Fix the unit firmly if mounted in a high place.)
Caution:
Do not use the air conditioner in such areas as a greasy area(including machine oil),
saline area(sea side), or sulphuric area(hot spring). When using the air conditioner in these areas, special maintenance is
required. Contact your local dealer or our service center for advice.

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 = 18˚C, 75˚F
FAN SPEED = HIGH
3. Set temperature indicating (setting) range : 1˚C interval from 18˚C to 30˚C.
1˚F interval from 64˚F to 86˚F.
3-2-2 Fan operation mode
1. If "Fan operation mode" signal is received from remocon.
➔ the compressor is immediately turned off and only fan motor is operated at set blowing speed.
➔ it changes such as "HIGH ➔MED ➔ LOW"( if Fan speed is selected).
2. The initial FAN speed is set to "HIGH".
3. The set temperature can not be indicated and set.
3-2-3 Energy Saver Operation
● If the compressor turn off at the cooling operation, the fan motor turn off after operating during the fixation time only,
and operation that save energy by turn off the fan motor continuously before the condition of the compressor on.
● The fan motor is not operated at flow wind operation.
1. 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
3) After the fan motor off, the compressor and fan motor is operated normally when the compressor on.

1. Replacing the compressor - Do not fill the system with oil as the compressor is already charged.
2. Replacing the condenser - Refill 50cc.
3. Replacing the evaporator - Refill 50cc.
4. Replacing the refrigerant - Refill 30cc.
5. The high pressure side is filled up with oil after the vacuum is completed.
6. When the refrigerant leaks, it is generally not necessary to refill the oil if the leakage is not severe.
