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.
