When You Think That Trouble Has Occured - Mitsubishi Mr.Slim MS12TN Operating Instructions Manual

S¸
The air conditioner
cannot be operated
for about 3 minutes
when restarted.
• This protects the air conditioner according to in-
structions from the microprocessor. Please wait.
Cracking sound is
heard.
• This sound is generated by the expansion/con-
traction of the front panel, etc. due to change in
temperature_
The room smells
strange.
• The air conditioner sucks in an odor adhering to
the wall, carpet, furniture, cloth, etc. and blows it
out with the air.
The fan stops during
the DRY operation.
• In DRY operation, the unit operates using the
same refrigerant circuit as in COOL operation.
DRY operation time has to be reduced in order to
lower humidity without much room temperature
decreasing. So the compressor sometimes stops,
and at the same time the indoor fan stops. This
prevents water condensed on the heat exchanger
from evaporating again.
The sound of water
flowing is heard.
• This is the sound of refrigerant flowing inside the
air conditioner.
• This is the sound of condensed water flowing in
the heat exchanger.
• This is the sound of the heat exchanger defrost-
ing.
The air flow direc-
tion changes during
operation.
• When the air conditioner is operated in COOL or
DRY mode, if the operation continues with air
blowing down for 1 hour, the direction of the air
flow is automatically set to horizontal to prevent
condensed water from dropping.
