Hoshizaki KM-201BWH Pump-Out Frequency Control S1 dip switch 5, Freeze Timer S1 dip switch 9

Pump-out cycle always occurs on the 2nd harvest after startup. Then, depending on the pump-out frequency control setting (S1 dip switch 5 & 6), pump-out cycle occurs every cycle, or every 2nd, 5th, or 10th cycle.

d) Pump-Out Frequency Control (S1 dip switch 5 & 6)

The water tank drains at the frequency set by the pump-out frequency control.

The pump-out 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 pump-out more often, the pump-out frequency can be adjusted as shown in the table below.

Dip Switch Setting		Frequency
No. 5	No. 6
OFF	OFF	every cycle
ON	OFF	every 2 cycles
OFF	ON	every 5 cycles
ON	ON	every 10 cycles

e) Harvest Pump Timer (S1 dip switch 7 & 8)

The harvest pump 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 harvest pump timer setting), whichever is shorter. When the water valve closes, the pump motor energizes and runs for the time determined by the harvest pump timer setting.

The harvest pump timer is factory-adjusted, and no adjustment is required.

Dip Switch Setting		Time
No. 7	No. 8	(seconds)
OFF	OFF	0
ON	OFF	10
OFF	ON	30
ON	ON	50

f) Freeze Timer (S1 dip switch 9 & 10)

CAUTION

Adjust to proper specification, or the unit may not operate correctly.

The freeze timer setting determines the maximum allowed freeze time to prevent possible freeze-up issues. Upon termination of freeze timer, machine initiates the harvest cycle. After 2 consecutive timer terminations, machine will shut down, possibly indicating a problem.
