Tips on using air conditioner
Here are some tips that you would follow when using your air conditioner.
TOPIC RECOMMENDATION
Cooling
• If current outside temperatures are much higher than
the selected indoor temperature, it may take time to
bring the inner temperature to the desired coolness.
• Avoid drastically turning down the temperature.
Energy is wasted and the room does not cool faster.
Heating
• Since the air conditioner heats the room by taking
heat energy from outdoor air, the heating capacity
may decrease when outdoor temperatures are
extremely low. If you feel the air conditioner
insufficiently heats, using an additional heating
appliance in combination with the air conditioner is
recommended.
Frost & De-ice
• When the air conditioner runs in Heat mode, due to
temperature difference between the unit and the
outside air, frost will form.
If this happens:
- The air conditioner stops heating.
- The air conditioner will operate automatically in
De-ice mode for 10 minutes.
- The steam produced on the outdoor unit in De-ice
mode is safe.
• No intervention is required; after about 10 minutes,
the air conditioner operates again normally.
NOTE The unit will not operate when it starts to de-ice.
Fan
• Fan may not operate for about 3~5 minutes at the
beginning to prevent any cold blasts while the air
conditioner is warming up.

14
Using your air conditioner
TOPIC RECOMMENDATION
High indoor/
outdoor
temperatures
• If both indoor and outdoor temperatures are high
and the air conditioner is running in Heat mode, the
outdoor unit’s fan and compressor may stop at times.
This is normal; wait until the air conditioner turns on
again.
Power failure
• If a power failure occurs during the operation of the
air conditioner, the operating immediately stops
and unit will be off. When power returns, the air
conditioner will run automatically.
Protection
mechanism
• If the air conditioner has just been turned on after
operation stops or being plugged in, cool/warm
air does not come out for 3 minutes to protect the
compressor of the outdoor unit.

If the air conditioner will not be used for an extended period of time, dry the air conditioner to maintain it in best
condition.
1. Dry the air conditioner thoroughly by operating in Fan mode for 3 to 4
hours and disconnect the power plug. There may be internal damage if
moisture is left in components.
2. Before using the air conditioner again, dry the inner components of the
air conditioner again by running in Fan mode for 3 to 4 hours. This helps
remove odors which may have generated from dampness.
