SPLIT-TYPE ROOM AIR CONDITIONER

10
Do not touch the metal parts of the unit when removing the filter.
Injuries can occur when handling sharp metal edges.
Do not use water to clean inside the air conditioner. Exposure to water
can destroy the insulation, leading to possible electric shock.
When cleaning the unit, first make sure that the power and circuit
breaker are turned off.
Do not wash air filter with hot water at more than 40º C / 104º
F. Shake off moisture completely and dry it in the shade. Do not
expose it directly to the sun, it may shrink.
NORMAL FUNCTION OF THE AIR CONDITIONER
The following events may occur during normal operation.
Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3-4 minutes after it stops.
Anti-cold air (Cooling and heating models only)
The unit is designed not to blow cold air on HEAT mode, when
the indoor heat exchanger is in one of the following three
situations and the set temperature has not been reached.
When heating has just started.
Defrosting.
Low temperature heating.
The indoor or outdoor fan stop running when defrosting
(Cooling and heating models only).
Defrosting (Cooling and heating models only)
Frost may be generated on the outdoor unit during heat cycle
when outdoor temperature is low and humidity is high resulting
in lower heating efficiency of the air conditioner.
During this condition air conditioner will stop heating operation
and start defrosting automatically.
The time to defrost may vary from 4 to 10 minutes according to
the outdoor temperature and the amount of frost built up on
the outdoor unit.
A white mist coming out from the indoor unit
A white mist may generate due to a large temperature
difference between air inlet and air outlet on COOL mode in an
indoor environment that has a high relative humidity.
A white mist may generate due to moisture generated from
defrosting process when the air conditioner restarts in HEAT
mode operation after defrosting.
Low noise of the air conditioner
You may hear a low hissing sound when the compressor is
running or has just stopped running.
It is the sound of the refrigerant flowing or coming to a stop.
You can also hear a low "squeak" sound when the compressor
is running or has just stopped running. This is caused by heat
expansion and cold contraction of the plastic parts in the unit
when the temperature is changing.
A noise may be heard due to louver restoring to its original
position when power is turned on.
Dust is blown out from the indoor unit.
This is a normal condition when the air conditioner has not
been used for a long time or during first use of the unit.
A peculiar smell comes out from the indoor unit.
This is caused by the indoor unit giving off smells permeated
from building material, from furniture, or smoke.
The air conditioner turns to FAN only mode from COOL or
HEAT (For cooling and heating models only) mode.
When indoor temperature reaches the temperature setting on
air conditioner, the compressor will stop automatically, and the
air conditioner turns to FAN only mode. The compressor will
start again when the indoor temperature rises on COOL mode
or falls on HEAT mode (For cooling and heating models only) to
the set point.
The air conditioner runs Anti-mildew function after turning
off the unit.
When turning off the unit under COOL(AUTO COOL, FORCED
COOL) and DRY mode, the air conditioner will run Anti-mildew
function for 7-10 minutes, if turns off on HEAT mode, the unit
will then stop the operation continue operating for about 30
seconds at LOW fan speed and turn off the unit automatically.
Dripping water may generate on the surface of the indoor unit
when cooling in a high relatively humidity (relative humidity
higher than 80%). Adjust the horizontal louver to the maximum
air outlet position and select HIGH fan speed.
Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit
and releases it via the indoor unit during heating operation.
When the outdoor temperature falls, heat drawn in by the
air conditioner decreases accordingly. At the same time, heat
loading of the air conditioner increases due to larger difference
between indoor and outdoor temperature. If a comfortable
temperature can't be achieved by the air conditioner, we
suggest you use a supplementary heating device.
Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power
restores, the OPERATION indicator on the indoor unit starts
flashing. To restart the operation, push the ON/OFF button on
the remote controller. For the unit with Auto-restart feature,
when the power restores, the unit restarts automatically with
all the previous settings preserved by the memory function.
