OPERATION TIPS
OPERATION TIPS
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protection
The compressor can't restart for 3 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.
A) When heating has just starting.
B) Defrosting.
C) 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 build up on the outdoor unit.
2. 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.
3. Low noise of the air conditioner
You may hear a low hissing sound when the compressor is running or has just stopped
running.
This sound 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 first
turned on.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
