(c) The following operations are performed during drying inside operation.

2. Start conditions for drying inside operations

(a) Automatic drying inside mode - This mode starts when the Drying inside button is set to ON, and any of the following

conditions are met.

(b) Drying inside operates according to the following steps

• Step 1: Moisture is allowed to drip from the heat exchanger. The louvre is positioned upwards at 90˚.
• Step 2: Moisture on the heat exchanger is dried with air.
• Step 3: Moisture on the heat exchanger is dried with heat.
• Step 4: The heat exchanger is cooled if the temperature rises too high.
• Step 5: Internal humidity is discharged in Step 4, and the louvre moves to the closed position.

(c) Step 3 does not perform the tube temperature or room temperature check that accompanies a microprocessor reset,

and jumps directly to Step 5.

(d) Mechanisms operated in the above steps (* are deemed E

2

PROM data.)

(e) Drying inside operation does not stop even if tank full is detected.
