Hoshizaki KM-650MAH, KM-650MRH, KM-650MWH service manual Pump-Out Frequency Control dip switch 5

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

The pump motor drains the water tank 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 drain 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

f) Freeze Timer (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.

The freeze timer is factory adjusted and no adjustment is required.

Dip Switch Setting		Time
No. 9	No. 10	(minutes)
OFF	OFF	60
OFF	ON	50
ON	OFF	70
ON	ON	60

g) Bin Control

CAUTION

When the ambient temperature is below 45°F (7°C), the bin control thermostat operates to stop the icemaker even if the ice storage bin is empty. When the thermostat is set in the prohibited range, the icemaker operates continuously even if the ice storage bin is filled with ice. Setting in the prohibited range might cause severe damage to the icemaker resulting in failure.

No adjustment is required under normal use, as the bin control is factory-adjusted. Adjust it, if necessary, so that the icemaker stops automatically within 10 seconds after ice contacts the bin control thermostat bulb.
