Features of your new air conditioner
• Cool Summer Oer
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 Ecient System
Your new air conditioner not only provides maximum cooling power in the summer, but can
also be an ecient heating method in the winter with the advanced “Heat pump” system.
This technology is up to 300% more ecient 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 oers dierent solutions for any
shape room allowing for specic air ow requirements. Also, the air intake can be set up on
either the bottom or rear of the unit, so there is more exibility in installation.
For easy future reference, write the model and serial
number down. You will nd your model number on the
bottom right side of the air conditioner.

Using your air conditioner
TIPSONUSINGAIRCONDITIONER
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 insuciently 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 dierence
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
Power failure • If a power failure occurs during the operation of the air conditioner, the
Protection
mechanism
• 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.
operating immediately stops and unit will be o. When power returns, the
air conditioner will run automatically.
• 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.

Cleaning 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.
MAINTAININGYOURAIRCONDITIONER
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.

The checks and maintenance operations described are essential to guarantee the
eciency of the air conditioner. The frequency of these operations varies according to the
characteristics of the area, the amount of dust, etc.
(1) The described operations should be performed more frequently if the area of
installation is very dusty.
(2) These operations must always be performed by qualied personnel. For more detailed

Refer to the following chart if the air conditioner operates abnormally. This may save time and
unnecessary expenses.
PROBLEM SOLUTION
The air conditioner does not
operate immediately after it has
been restarted.
The air conditioner does not work
at all.
The temperature does not change. • Check if you selected Fan mode.
The cool (warm) air does not come
out of the air conditioner.
The cool (warm) air does not come
out of the air conditioner.
The fan speed does not change. • Check if you selected Auto or Dry mode.
Timer function does not set. • Check if you press the Power button on the remote control after you have set the time.
Odors permeate in the room
during operation.
The air conditioner makes a
bubbling sound.
Water is dripping from the air ow
blades.
Remote control is not working. • Check if your batteries are depleted.
The air conditioner does not turn
on or o with the wired remote
control.
The wired remote control does not
operate.
The indicators of the digital display
ashes.
• Because of the protective mechanism, the appliance does not start operating
immediately to keep the unit from overloading.
The air conditioner will start in 3 minutes.
• Check that the power plug is properly connected. Insert the power plug into the wall
socket correctly.
• Check if the circuit breaker is switched o.
• Check if there is a power failure.
• Check your fuse. Make sure it is not blown out.
Press the Mode button on the remote control to select another mode.
• Check if the set temperature is higher (lower) than the current temperature. Press the
Temperature button on the remote control to change the set temperature. Press the
Temperature button to decrease or increase the temperature.
• Check if the air lter is blocked by dirt.
• Check if the air conditioner has just been turned on. If so, wait 3 minutes. Cool air does
not come out to protect the compressor of the outdoor unit.
• Check if the air conditioner is installed in a place with a direct exposure to sunlight.
Hang curtains on windows to boost cooling eciency.
• Check if the cover or any obstacle is not near the outdoor unit.
• Check if the refrigerant pipe is too long.
• Check if the air conditioner is only available in Cool mode.
• Check if the remote control is only available for cooling model.
The air conditioner automatically adjusts the fan speed to Auto in Auto/Dry mode.
• Check if the appliance is running in a smoky area or if there is a smell entering from
