Drain Cycle
a)
1-in-1 Drain Cycle:
DV energizes once every hour when the 1-in-1 drain cycle is
activated (S1 dip switch 4 in the "OFF" position (factory default position)).
GM and PDS continue. DV energizes for 2 sec. every hour. This setting is recommended
for optimum icemaker performance. The 1-in-1 drain cycle allows any sediment to drain
from the evaporator without interrupting the icemaking process.
b)
1-in-12 Drain Cycle (optional):
DV energizes once every 12 hours when the 1-in-12
drain cycle is activated (S1 dip switch 4 in the on position (optional)). 12-hour drain
cycle timer terminates, PDS de-energizes, GM continues. The 5-min. ice purge timer
starts. When the 5-min. ice purge timer terminates, GM de-energizes. 10-min. DT starts,
DV energizes. After 10-min. DT terminates, DV de-energizes and 12-hour drain cycle
timer starts. Icemaking process restarts.
c)
Manual Drain:
Manual drain is used when servicing evaporator components and
cleaning and sanitizing the unit. When the unit is making ice and the control switch is
moved to the "DRAIN" position, there is a 3 sec. delay, then PDS de-energizes and
the 5-min. ice purge timer starts. When the 5-min. ice purge timer terminates, GM
de-energizes. DV energizes to drain the evaporator and reservoir. To avoid the 5-min.
shutdown delay, turn off the power supply, then move the control switch to the "DRAIN"
position. Turn on the power supply. DV energizes to drain the evaporator and reservoir.
DV de-energizes when the control switch is moved to the "ICE" position
