Thawing Timer. (Part of PLC)
Thawing Timer. The thawing timer governs the ice thawing period. It is built into the PLC located
inside the control panel. It is started by action of one of the freezer pressure switches (FPS1 or
FPS2) or the manual harvest button. This timer is set prior to shipment for approximately a 90
second period.
Set the thawing period for at least 20 seconds longer than the time required to harvest the entire
discharge of ice. If it should be necessary to change the setting of the timer, turn the adjustment
screw clockwise to increase the time or counter-clockwise to decrease the time. Check thaw time
after each adjustment FIGURES 6-1 & 9-6.
FIGURE 9-7
Ice Selector Switch (Dual Ice Type Only)
Ice Selector Switch. A 3-position rotary-type switch marked “Cru-Auto-Cyl” is located in the
switch box (FIGURE 6-2). Set this switch on “Auto” to produce and store both cylinder and crushed
ice in a divided bin with two thermostats. To continuously produce either type of ice, set switch to
“Cru” for crushed ice only or to “Cyl” for cylinder ice only.
