features of your new
air conditioner
• Cool Summer Offer
On those hot sweltering summer days and long restless nights, there is no better escape
from the heat than the cool comforts of home. Your new air conditioner brings an end to
exhausting hot summer days and lets you rest. This summer, beat the heat with your own
air conditioner.
• Cost Efficient System
Your new air conditioner not only provides maximum cooling power in the summer, but can
also be an efficient heating method in the winter with the advanced “Heat pump” system.
This technology is up to 300% more efficient than electrical heating, so you can further
reduce its running cost. Now, meet year-round needs with one air conditioner.
• Flexible installation
Duct type air conditioner is designed to be slimmer and offers different solutions for any
shape room allowing for specific air flow requirements. Also, the air intake can be set up on
either the bottom or rear of the unit, so there is more flexibility in installation.
For easy future reference write the model and serial number
down. You will find your model number on the right side of
the air conditioner.

TIPS ON USING YOUR 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.
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.
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.
10_ using your air conditioner
cleaning and maintaining the
air conditioner
For the best performance from your air conditioner, clean it periodically. When cleaning, make sure to
unplug from the unit for user’s safety.
When cleaning the filter, make sure to unplug the power from the unit. Washable foam based Air filter
captures large particles from the air. The filter is cleaned with a vacuum or by hand washing.
Slim duct type
1. Way 1 : Slide out the Air filter on the rear side panel to the right side.
Way 2 : Take out the Air filter from the panel.
2. Clean the Air filter with a vacuum cleaner or soft brush. If dust is too heavy, then rinse it with
running water and dry it in a ventilated area.
• For best conditions, repeat every two weeks.
• If the Air filter dries in a confined (or humid) area, odors may generate. If it occurs,
re-clean and dry it in a ventilated area.
3. Way 1 : Insert the filter back in its original position.
Way 2 : Insert the filter back in its original position.
