Precautions
Caution
Do not obstruct the front of discharge grille
of both units.
This will block air flow, reduce the cooling
effect, and may result in unit malfunction.
Danger
Do not put hands or objects into the
discharge grille of outdoor unit.
These units have a fan running at high
speed. It is very dangerous to touch the fan.
Caution
Ventilate the room air when the room
becomes stuffy or filled with undesirable
odors.
Danger
Use only fuses of the proper amperage.
If using rewirable fuse, use only the correct
fuse wire as fire or electrical hazard may
occur.
Caution
Keep heat sources away from the unit; High
temperature can cause damage.
Caution
Be careful to keep room temperature
comfortable.
Avoid continuous direct air flow on to the
occupant, especially in case of those
sleeping or a patient.
Caution
Set a comfortable temperature.
Very low or very high temperature setting
considerably increase power consumption.
Caution
If you want to only circulate the room air,
operate FAN mode.
Caution
In summer, if possible, prevent direct
sunlight from entering the room; draw
curtains or blinds.
Caution
Use the timer correctly to maintain comfort conditons. Caution Please read this owner’s manual carefully before operating the unit.

Care and maintenace
Points to note
Operating Condition
• Temperature ranges which are suitable for unit operation are as follows.
• When the unit is operated above or below these conditions for a long time, system diagnostics may detect a malfunction and the unit will
not operate properly.
• If the unit is operated for a long time under abnormal situation of extreme high humidity, condensate water may drip from the unit.
Time Delay
• If the operating mode is changed during operation from COOL or DRY to HEAT, or from HEAT to COOL or DRY, there will be a 3 minute
time delay (heat pump only).
• If you start operation after power is turned off, there will be a 3 minute time delay also.
• When the heating operation is started, hot air delivery might be delayed due to warm up period. This period may be 2~5 minutes (heat
pump only).
Heating Features (Heat pump only)
• When the unit is started in heating mode, there will be a preheating period of 2~5 minutes before the unit is ready to deliver warm air.
• When the outdoor temperature is low, the heating capacity will be reduced. If the room air is not warm enough during severe winter
condition, use additional heating devices.
Defrost Operation (Heat pump only)
• In heating mode, when the outdoor coil is frosted, the indoor fan and outdoor fan are turned off while the compressor is being turned on to
remove the frost of the outdoor coil.
• The defrost mode stops after 10 minutes or when the outdoor coil temperature is greater than or equal to 17°C.
Auto Recovery
• When the electricity is failure during the unit is operating, the unit memorizes the operating condition, and the unit starts operation
automatically after the electricity is recovered.
• When you leave home after the electricity is failure, please unplug the power cord.
Frost Prevention of Indoor Unit
When the unit is operated at low ambient temperature, frost may be appeared on the indoor coil. When the indoor coil temperature is below
0°C, the microcomputer makes the compressor stop to protect the unit from the frost.
Normal Operation
Any of the followings can occur during normal operation.
• A sound like a "GURGLE" can sometimes be heard during operation or when the unit stops.
- It is the sound of refrigerant flowing through the unit.
• The bad smells come from the unit.
- Smells such as smoke or cosmetics can accumulate while room air circulates through the unit.
- Cleaning filters will reduce this problem.
Heat pump only:
• Outdoor fan does not rotate during heating operation.
- The unit is in defrost mode.
• UNIT ON lamp on the indoor unit display flash and wind not comes from the unit.
- It indicates malfunction of the unit and makes the compressor be turned off.
• A “BAK-BAK” sounding noise can be sometimes heard during operation or when the unit turns on.
- It is the sound of plastic expansion due to abrupt heat change.
