Thawing Timer (T). The thawing timer governs the ice thawing period. It is located inside the
control panel (FIGURE 6-1). It is started by action of the freeze timer (T2), which energizes the
“1CR” relay. This timer is set prior to shipment for approximately a two-minute period.
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.

Freeze Timer (T2). The freezing time period for the production of cylinder or crushed ice is
controlled by the freeze timer mounted on the control panel door.
The timer was set at the factory to a default of 10 minutes. The freeze time can be adjusted to
compensate for water temperature and refrigeration system conditions. Do not make adjustments
until several ice-discharging cycles have been made.
