Checking before use
Operation ranges
The table below indicates the temperature and humidity ranges the air conditioner can be
operated within. Refer to the table for ecient use.
MODE OPERATIONAL TEMPERATURE INDOOR HUMIDITY IF OUT OF CONDITIONS
INDOOR OUTDOOR
COOLING 18˚C to 32˚C -20˚C to 50˚C 80% or less Condensation may occur on the indoor unit
with risk to have either water blow o or
drops on the oor.
Internal protection triggers and the air
conditioner will stop.
DRYING 18˚C to 32˚C -20˚C to 50˚C -
HEATING 27˚C or less -25˚C to 24˚C - Internal protection triggers and the air
conditioner will stop.
• Be sure to install the unit under circumstances within the allowable range of
temperature. (Extended operation range down to -25 °C in heating.)
CAUTION
• The standardized temperature for heating is 7˚C. If the outdoor temperature drops to 0˚C or below, the heating
capacity can be reduced depending on the temperature condition.
• If the cooling operation is used at over 32˚C(indoor temperature), it does not cool at its full capacity.
NOTE
• The use of the air conditioner at a relative humidity above the expected one (80%)
may cause the formation of condensate and the leakage of water drops on the
oor.
CAUTION
Maintaining your air conditioner
Internal protections via the unit control system
f This internal protection operates if an internal fault occurs in the air conditioner.
Type Description
Against cold air The internal fan will be o to block cold air when the heat pump is heating.
Defrost cycle The internal fan will be o to block cold air when the heat pump is heating.
Anti-Freezing of Indoor Heat
Exchanger
The compressor will be o if the heat exchanger temp of indoor unit decrease to 0°C or
more to protect the ice on the heat exchanger.
Protect compressor The air conditioner does not start operating immediately to protect the compressor of the
outdoor unit after it has been started.
• If the heat pump is operating in Heat mode, Defrost cycle is actuated to remove frost from an outdoor unit that
may have deposited at low temperatures. The internal fan is switched o automatically and restarted only after
the Defrost cycle is completed.

Checking before use
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
insuciently heats, using an additional heating appliance in
combination with the air conditioner is recommended.
Frost
• When the air conditioner runs in Heat mode, due to temperature
dierence 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 Defrost mode for
10minutes.
- The steam produced on the outdoor unit in Defrost 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.

11
ENGLISH
TOPIC RECOMMENDATION
Power failure
• If a power failure occurs during the operation of the air conditioner, the
operating immediately stops and unit will be o. 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.
Automatic air
ow blade
control
• If the air conditioner is operating in abnormal conditions (such as
operating the air conditioner with windows open or when small
capacity indoor unit is installed and operating in a room that is too
large) indoor can become very humid when the angle of the air ow
blade is small and performance of the product may decrease. When
indoor humidity increases, indoor unit will automatically detect it and
open the air ow blade in wider angle to make sure that performance
of the product is stable.

Cleaning and maintaining the air conditioner
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.

Troubleshooting
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.
• 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.
The air conditioner does
not work at all.
• 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.

come out of the air
conditioner.
• 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. Clean the air lter every
two weeks.
• 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 eciency.
• 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.

temperature.
Remote control is not
working.
• Check if your batteries are depleted.
• Make sure batteries are correctly installed.
• Make sure nothing is blocking your remote control sensor.
• Check that there are strong lighting apparatus near the air
conditioner. Strong light which comes from uorescent bulbs or
neon signs may interrupt the electric waves.
The air conditioner
does not turn on or o
with the wired remote
control.
• Check if you set the wired remote control for group control.
The wired remote
control does not
operate.
• Check if TEST indicator is displayed on the wired remote control.
