c) Drain Timer (S1 dip switch 3 & 4)
Once every ten freeze cycles, the drain valve opens to drain the water tank for the time
determined by the drain timer. These switches also determine the time to delay completion
of a harvest cycle, i.e. the minimum harvest time.
Do not change this setting, or the unit will not operate properly or produce high quality ice.

T2: Harvest timer at drain
Drain cycle always occurs on the 2nd harvest after startup. Then, depending on the drain
frequency control setting (dip switch 5 & 6), drain cycle occurs every cycle, or every 2nd, 5th,
or 10th cycle.
d) Drain Frequency Control (S1 dip switch 5 & 6)
The water tank drains at the frequency set by the drain frequency control.
The drain frequency control is factory-adjusted to drain the water tank every 10 cycles, and
no adjustment is required. However, where water quality is bad and the icemaker needs a
drain more often, the drain frequency can be adjusted as shown in the table below.

e) Water Saver Timer (S1 dip switch 7 & 8)
The water saver timer allows the water valve to close and the pump motor to circulate water
in the tank during the final part of harvest. The water valve is open during harvest for a
maximum of 6 minutes or the length of harvest minus 0, 10, 30, or 50 seconds (determined
by the water saver timer setting), whichever is shorter. When the water valve closes, the
pump motor energizes and runs for the time determined by the water saver timer setting.
The water saver timer is factory-adjusted, and no adjustment is required.
