The length of this timed portion of the freeze cycle is pre-fixed and related to the setting of the first
four DIP SWITCH keys. The DIP SWITCH key settings are made in consideration of the type of
condenser used and size of ice cubes.
Table B indicates the various lengths of the timed portion of the freeze cycle in relation to the different
combinations of the DIP SWITCH keys. The electrical components in operation during the freeze cycle
are the compressor, fan motor, and water pump. During the second phase of the freeze cycle (time
mode), they are joined by the electronic timer.
The condenser temperature sensor senses a rising of the condenser temperature beyond the pre-
fixed limit, changes its electrical resistance, and transmits a low voltage power flow to the
microprocessor of the PC Board, which in turn energizes the fan motor.
When the opposite situation occurs, i.e. the condenser temperature gets below the pre-fixed limit,
the temperature sensor changes again its electrical resistance reducing the current flow to the PC
Board, causing the fan motor to temporarily cut off.
In case the condenser temperature probe senses that the condenser temperature has risen to 160˚F
(70˚C), the cause is one of the following reasons:
• C
logged condenser
• Fan motor malfunction
• Ambient temperature higher than 100˚F (40˚C)
The reasons above will cause the total and immediate shut off of the machine in order to prevent the
unit from operating in abnormal and dangerous conditions. When the ice maker stops on account of
this protective device, there is a simultaneous glowing of the RED LED and RED LIGHT (STEADY),
warning the user of the HIGH TEMPERATURE situation. After having eliminated the source of the
condenser high temperature, restarting the machine is necessary. The ice machine will resume its
normal operation by going through the 5-minute water fill phase.

EFROST OR HARVEST CYCLE (FIG. E AND G)
As the electronic timer has carried the system throughout the second phase of the freeze cycle, the
defrost cycle begins.
NOTE: If after 15 minutes in the freeze cycle the temperature of the
evaporator sensor probe is higher than 32˚F (0˚C) – small red LED still OFF –
(shortage of refrigerant, inoperative hot gas valve, etc.) the PC Board will
switch the unit OFF immediately with the simultaneous blinking of the
WARNING RED LED.
