While cooling, the
compressor sometimes stops
abruptly.
Q1
Check whether frost sticks
on the heat exchanger of in-
door unit or not.
Wait for 3 – 4 minutes until
the frost melts.
A1
If cooling is performance
when the room temperature
is low, frost may stick on the
heat exchanger of indoor
unit.
Cooling operation
The fan speed does not
change during a
dehumidifying operation.
Q2
Dehumidifying operation
The fan speed is always LO
at a dehumidifying operation.
A2
Cold air comes out during a
dehumidifying operation.
Q3
To improve the dehumidi-
fication efficiency, LO fan
speed operation is
performed. Therefore the air
is cold. This is not a trouble.
A3
The operation does not stop
even by raising the room
temperature setting of remote
control at a dehumidifying
operation.
Q4
At a dehumidifying operation,
the actual room temperature is
compared with the room tem-
perature setting when starting
the operation and the opera-
tion is as follows.
1) When actual room tem-
perature > room tempera-
ture setting.
The operation is according
to the room temperature
setting on the remote con-
troller.
2) * When actual room tem-
perature < room tempera-
ture setting
Regardless of the room
temperature setting, the
temperature is automati-
cally set slightly lower than
the room temperature.
In this case, the status is as 2)
and, therefore, the operation
by the room temperature
control is impossible. Turn off
the On / OFF switch, set the
room temperature to a new
value and turn on the opera-
tion by the On / Off switch.
A4
In the dehumidifying mode,
the temperature set by
remote controller is set
slightly higher than the room
temperature but the
operation starts.
Q5
This is the status in 2) of
(A4). The temperature is set
a little lower than the room
temperature to carry out a
dehumidifying operation as
far as possible.
