TIPS ON USING AIR CONDITIONER
TOPIC
Cooling
RECOMMENDATION
•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.
ENGLISH
Here are some tips that you would follow when using your
air conditioner.

TOPIC
RECOMMENDATION
Frost & De-ice -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.
T
he 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/ •If both indoor and outdoor temperatures
outdoor
are high and the air conditioner is running
temperatures in Heat mode, the outdoor unit’s fan and
compressor may stop at times. This is
normal; wait until the air conditioner turns
