1GENERAL INFORMATION

1.1 Specific features

The “Mitsubishi Daiya” room air-conditioner: SRK series are of split and wall mounted type and the unit consists of indoor unit and

outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling or heating equipment with opera-

tion control switch and the outdoor unit is composed of condensing unit with compressor.

(1) Remote control flap

The flap can be automatically controlled by operating wireless remote controller.

¡Air scroll: Flap operation is automatically control.

¡Swing: This will swing the flap up and down.

¡Memory flap: Once the flap position is set, the unit memorizes the position and continues to operate at the same position from

the next time.

(2) Automatic operation

When the remote control switch is set on “auto( ) ”, it will either automatically decide operation mode such as cooling, heating

and thermal dry, or operate in the operation mode before it has been turned to automatic control.

(3) Self diagnosis function

¡We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation as

follows.
