Thawing Timer.
The thawing timer governs the ice thawing period. It is located inside the control
panel (FIGURE 6-2). It is started by action of the freezer pressure switch (FPS) which energizes the
“CR” relay. This timer is set prior to shipment for approximately a two minute period.
FIGURE 9-14A
Thawing Timer
Set the thawing period for at least 30 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.
