2. OPERATION

This service manual specifies the basic operation of the controller board "Ver. 1.4A".

[a] SOFT START

1) When the power supply is turned on, the 7-segment LED shows "on" and the hot gas
valve opens. After 30 seconds, the defrost cycle starts.
* If the reset switch is pressed during the 30-second standby time, the unit resets
soft start and immediately starts operation.

[b] WATER PAN OPENS

1) The hot gas valve opens, the actuator motor starts, and the water pan starts to open.
2) After 20 seconds, the water valve opens to supply defrosting water (water pan
cleaning water) for a specific time.
* The defrosting water supply time varies between the water temperatures above
and below 13°C.
* In the initial cycle, the water temperature is not detected and assumed to be below
13°C, resulting in a longer defrosting water supply time.
* The defrosting water supply time is adjustable in the maintenance mode (see "3. [b]
MAINTENANCE MODE").
