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 later-intermittent 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 mal-
function 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.
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
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.
3-1-1 Selecting Area for Installation
• 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 Controls and Components
3-2-1 Thermostat
 OFF
When the room temperature is lowered by the air condition-
er, the gas within the thermostat will contract and cause a
break in the electric contact. The compressor will then stop.
After the compressor 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.
3-2-1 Thermostat
 Control Operation
By turning the control knob clockwise(toward higher
numbers), the temperatures will be cooler.
By turning the control knob counterclockwise (toward lower
numbers), the temperature will be warmer.
Level 01 : Cool air will be supplied above 30~35˚
Level 10 : Cool air will be ceased below 28~32.5˚
Level 10 : Cool air will be supplied above 17.4~20.4˚
Level 10 : Cool air will be ceased below 14.4~17.4˚

Installation and Operating Instructions
3-2-2 Operation
The fan selector switch offers high and low fan cooling control 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 controls cool, dehumidify, filter, and circulate room air,
with the fan continuing to circulate air even when the compressor is turned off.
3-2-3 Air swing switch
• On : Automatic oscillation distributes the air flow throughout the room. (controls left the right and left blade-V.)
• Off : Maintains a fixed direction of air flow, Set the Air switch to OFF at the instant the wave fins come to the desired
position.
3-2-4 Fan speed switch
The fan speed switch offers high and low fan cooling control 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 activate the air conditioner)hese controls cool, dehumidify, filter, and circulate room air,
with the fan continuing to circulate air while the compressor is turned off.
3-2-5 Ventilation switch
Use the ventilation switch to exhaust stale air.
• Open position : The air inside the room circulates while the outdoor air is introduced inside.
• Closed position : The air inside the room circulates while the outdoor air is not introduced inside.

4-2 Checking the oil
4-2-1 Oil quality
4-2-2 Replacing and refilling the refrigerant oil
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.)
Fill the transparent container with 10cc of oil, and then conduct the test.
