Contact your dealer
■
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 the foreign matters enter the indoor unit through the
air outlets and the dumper becomes inoperable, call your
dealer.
A switch does not activate properly. You hear a strange noise during opera-
tion.
Fuse often blows.
The RUN and TIMER lights on the unit display section blink
quickly (0.5 sec. ON; 0.5 sec. OFF) and do not work.
CAUTION
If the power cord becomes damaged, ask your dealer or a qualified engineer to install the
replacement to avoid accidents.
When abnormalities occur, turn off the power supply immediately and turn it on after 3 minutes.
Restart the operation with ON/OFF button of the remote control and the abnormalities still continue.
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).
