6.
Contact an installation specialist for installation.
Plug in the power plug properly.
Use a dedicated circuit.
Do not use an extension cord.
Do not start/stop operation by plugging/unplugging the power cord.
If the cord/plug is damaged, replace it with only an authorized replacement
part.
Usage
1. Being exposed to direct airflow for an extended period of time could be
hazardous to your health. Do not expose occupants, pets, or plants to direct
airflow for extended periods of time.
2. Due to the possibility of oxygen deficiency, ventilate the room when used
together with stoves or other heating devices.
3. Do not use this air conditioner for non-specified special purposes (e.g.
preserving precision devices, food, pets, plants, and art objects). Such usage
could damage the items.
Cleaning and Maintenance
1. Do not touch the metal parts of the unit when removing the filter. Injuries can
occur when handling sharp metal edges.
2. Do not use water to clean inside the air conditioner. Exposure to water can
destroy the insulation, leading to possible electric shock.
3. When cleaning the unit, first make sure that the power and breaker are turned
off. The fan rotates at a very high speed during operation. There is a possibility
of injury if the unit’s power is accidentally triggered on while cleaning inner
parts of the unit.

Air Filter Cleaning
The air filter should be checked at least twice a month to see if cleaning is necessary. Trapped particles
in the filter will build up and block the airflow. This reduces the cooling capacity and also causes an
accumulation of frost on the cooling coils.
1 Open the inlet grille upward by pulling out the bottom of the inlet grille.(a)
In another case, you can open the inlet grille downward by pulling out the top of the inlet grille.(b)
2. Remove the air filter from the front grille assembly by pulling the air filter up or down slightly.
3. Wash the filter using lukewarm water below 40°C (104°F).(c)
4. Gently shake the excess water from the filter completely. Replace the filter.
NOTICE
Mark ∆ of inlet grille means opening direction.
How to Attach Front Grille to Cabinet
1. Pull down front grille from the cabinet top.
2. Push front grille’s tips toward the cabinet in
order to insert front grille’s tabs into

Maintenance and Service
Please check before service call
When you find something wrong with your room air conditioner, please check carefully referring
to the following items. If you can’t find out the causes of trouble, get into contact with your dealer.
A. WHEN AIR CONDITIONER DOES
NOT OPERATE;
B. WHEN AIR CONDITIONER DOES
NOT COOL AS IT SHOULD;
1. Is the air conditioner plugged into the
receptacle properly?
1. Is the operation switch set properly?
2. Is the unit connected to a live receptacle
supplying the proper voltage?
3. Is the fuse blown or is the automatic circuit
breaker off?
2. Is the thermostat control set properly to
provide the desired cooling?
3. Are there too many people than the usual
number in the room?
4. Is there a local power failure?
Try another electrical product.
4. Is the air circulation restricted by drapes,
furniture, etc., or by an improper vane
setting?
5. Has the air conditioner been accidentally
switched off?
5. Are the doors or windows open, or is there
an unusual heat source in the room?
6. Is the circuit overloaded by other devices on
the same line?
6. Is the ventilation damper closed for maximum
cooling?
7. Is the thermostat knob set too low comparing
to the temperature of indoor?
7. Is the air filter clean so that it will not obstruct
the air flow?
8. If an extension cord is used, is the wire
diameter large enough to carry the current?
8. Have all the steps outlined in the Installation
Instructions been followed?
9. Is the evaporator frosted? Frosting of the
evaporator may occur during the spring and
autumn months if there is a considerable
temperature drop or during cool weather. If
so, turn the operation switch to “MED FAN”.
The fast air circulation will quickly defrost the
coil so that normal cooling operating may be
resumed.

• If power failure occurs, turn the mode control to OFF.
When power is restored, wait 3 minutes to restart the air
conditioner to prevent tripping of the compressor
overload.
■ Airflow is restricted.
• Make sure there are no curtains, blinds, or furniture
blocking the front of the air conditioner.
■ The THERMOSTAT may
not be set high enough.
• Turn the knob to a higher number. The highest
setting provides maximum cooling.
■ TEMP Control set to a
higher number.
• Set the TEMP Control to a lower number.
■ The air filter is dirty.
• Clean the filter at least every 2 weeks.
See the operating instructions section.
■ The room may have been
hot.
• When the air conditioner is first turned on
you need to allow time for the room to cool down.
■ Cold air is escaping.
• Check for open furnace floor registers
and cold air returns.
• Set the air conditioner's vent to the closed position.
■ Cooling coils have iced up.
• See Air Conditioner Freezing Up below.
■ Ice blocks the air flow and
stops the air conditioner
from cooling the room.
• Set the mode control at Med Fan or High Cool with
the thermostat at 1 or 2.
• Set the mode control at High Fan or High Cool with
the high temperature.
