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.
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.
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.
