Thawing Timer.
The thawing timer (2TR), Figure 9-5, governs the ice thawing period. It is located
inside the control panel (FIGURE 6-1). It is started by action of the freezer pressure switch (2PS)
which energized the “1CR” relay. This timer is set prior to shipment for approximately a three
minute period. To replace the timer, simply pull the timer from its base and plug in another, set to
“X1” and “Min” and 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 dial clockwise to increase the time or counter-clockwise to decrease the time. Check
thaw time after each adjustment.
Note: Thicker ice may require a longer thaw period, due to slower ice release time.
