■ Pre-season Inspection
● Clean the air filters, re-insert and operate the air
conditioners.
● Is the discharged air cold / warm?
Operation is normal if 15 minutes after the start of
operation, the difference between the air intake and
outlet vents temperature is:-
● Are the air intake or outlet vents of the indoor or
outdoor units obstructed?
● Are the remote control batteries weak?
If the remote control display appears weak, replace
the batteries.
■ When the Air Conditioner is Not Used
for an Extended Period of Time

■ Recommended Inspection
•
After used over several seasons, the unit will become
dirty and thus decreases the unit’s performance.
Depending on the operation conditions, a dirty unit
may produce odour and dust may pollute
dehumidification system. Therefore, a seasonal
inspection is recommended in addition to regular
cleaning. (Consult an authorized dealer).

ENERGY SAVING AND OPERATION
HINTS
■ Setting the Temperature
• Approximately 10% of electricity can be saved.
• Set the temperature higher or lower than the
desired temperature.
Cooling Model
Cooling Operation : 1°C higher
Heat Pump Model
Cooling Operation : 1°C higher
Heating Operation : 2°C lower
■ Air Filters
• Clean the air filters every 2 weeks.
• Dirty filters may reduces cooling or heating
efficiency.
■ Keep All Doors and Windows Closed
• Otherwise, cooling or heating performance will be
reduced and electricity cost is wasted.
■ Outdoor Unit
• Do not block the air outlet vents. Otherwise, it will
lower the cooling or heating performance.
■ Timer and Sleep Mode
• To prevent wastage of electricity, use sleep mode
when sleeping or Timer when going out.
■ Avoid Direct Sunlight

TROUBLESHOOTING
■ Normal Operation
Is it okay?
• Air conditioner has been restarted, but does not
operate for 3 minutes.
• A sound like water flowing can be heard.
• It seems that fog is coming out from the air
conditioner.
• The room has a peculiar odour.
• The outdoor unit emits water or steam.
• During Automatic Airflow Volume setting,
indoor fan stops occasionally.
• (For Heat Pump Model only)
Operation stops for about 12 minutes during
heating (The power indicator blinks).
• (For Heat Pump Model only)
During heating operation, indoor fan may
run at on and off conditions.
■ Abnormal Operation
Is it okay?
• The air conditioner does not operate.
• Air conditioner produces loud noise during
operation.
• The air conditioner does not cool or warm
effectively.
• Remote control / display doesn’t work
This is the answer
• This is to protect the air conditioner. Wait until the air
conditioner begins to operate.
• This is the sound of refrigerant flowing inside the air
conditioner.
• Condensation occurs when the airflow from the air
conditioner cools the room.
• This may be a damp smell emitted by the wall,
carpet, furniture or clothing in the room.
• In COOL/DRY operation, moisture in the air
condenses into water on the cool surface of outdoor
unit piping that causes dripping.
• This is to remove the smell emitted by the
surroundings.
• This is to melt the frost which has accumulated on
the outdoor unit (defrosting operating). This will take
no longer than about 12 minutes. Water drips from
the outdoor unit. Wait until this operation ends.
(the power indicator will light up). (Frost will
accumulates on the outdoor unit when the outdoor
temperature is low and humidity is high.)
• This is to prevent undesired cooling effect during
heating operation.
Please check
• Has the circuit breaker been tripped?
• Has the power plug been removed from the wall
outlet?
• Is the timer being used correctly?
• Is the installation work slanted?
• Has the temperature been set incorrectly?
• Are the filters dirty?
• Are the intake or outlet vents of the outdoor unit
obstructed?
• Are all windows and doors closed?
• Batteries empty?
• Batteries correctly inserted (+) and (–)?
