■ 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
operation.
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.
About the Multiple Air-conditioner
Automatic Operation
Refrigerant (oil) recovery 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.
• When other indoor units are operating in different modes, the RUN light illuminates.
• 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 tem-
peratures 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.)
Simultaneous 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).
