About the multiple air-conditioners
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 change
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-conditioners, 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 mode. (This is only relevant when more than one air-conditioner unit is being used.)
• 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).
