When to contact your distributor without delay
■
Turn off the power switch immediately and inform your dealer in any of the following situations:
The fuse or switch blows continu-
ously.
The cable becomes extremely hot.
The covering of the cable is cracked.
The TV, radio or other equipment
starts to malfunction.
When faulty movement is observed when the ON/OFF but-
ton is pressed, even after turning off the power switch and
restarting the operation after 3 minutes, the faulty move-
ment does not disappear.
A switch does not activate properly.
You hear a strange noise during opera-
tion.
3 minutes go
by, but, why ...
Fuse often blows.
The RUN and TIMER lights on the unit indication section
blink quickly (0.5 sec. ON; 0.5 sec. OFF) and don’t work.
CAUTION
If the power cord becomes damaged, ask your dealer or a qualified engineer to install the
replacement to avoid accidents.
About the Multiple Air-conditioner
Simultaneous Operation
•
The air-conditioners cannot be in different operating modes at the same time, such as one unit being in the “Cool” mode and one unit being in
the “Heat” mode.
•
When conducting different operations, the air-conditioner that was operated first will be given priority, so the air-conditioner that is operated
after that will conduct air blowing operation.
•
When you want to give priority to the air-conditioner that was started later, either stop the air-conditioner that has priority or cause the
operation type of the unit operated first to match that of the unit operated second.
Automatic Operation
•
When the remote control operation switch is in the “Auto” mode the air-conditioner automatically selects either “Cool,” “Dry,” or “Heat” when
operation is started depending on the room temperature.
•
During simultaneous operation of air-conditioner units, operation modes may be automatically changed in response to the temperatures of the
individual rooms; this will result in the operation of the outdoor unit being stopped. In such a case, COOL or HEAT mode should be used
instead of AUTO. (This is only relevant when more than one air-conditioner unit is being used.)
Refrigerant (oil) recovery operation
•
If the all of the indoor units are not operated at the same time for an extended period, the cooling or heating performance may temporarily
decrease. This is in order to control the recovery of the refrigerant (oil) in the stopped indoor unit(s). At this time, the sound of refrigerant
flowing may be heard from the stopped indoor unit(s).
