Harvest Timer dip switch 1 | Hoshizaki DKM-500BAH guide

Check a thermistor for resistance by using the following procedure:

1)Disconnect the connector K3 on the board.

2)Remove the thermistor. See "V.H. Removal and Replacement of Thermistor."

3)Immerse the thermistor sensor portion in a glass containing ice and water for 2 or 3 minutes.

4)Verify the temperature of the glass, then check for resistance between thermistor leads. See the table above for temperature and resistance values. Normal reading is within 3.5 to 7 kΩ. Replace the thermistor if it exceeds the normal reading.

c)Harvest Timer (dip switch 1 & 2)

The harvest timer starts counting when the thermistor reads 48°F (9°C) at the evaporator outlet.

No adjustment is required under normal use, as the harvest timer is adjusted to the suitable position. However, a setting longer than the factory setting may be advised in cases where the ﬂush provided at harvest needs to be prolonged for extra cleaning. Before changing this setting, call the HOSHIZAKI Technical Support Department at

1-800-233-1940 for recommendations. Keep in mind that setting the harvest timer to a longer setting will decrease 24 hour production.

Dip Switch Setting		Time
No. 1	No. 2	(seconds)
No. 1	No. 2
OFF	OFF	60
ON	OFF	90
OFF	ON	120
ON	ON	180

d)Pump-Out Timer (dip switch 3 & 4)

When a freeze cycle is completed, the pump motor stops, and the icemaker resumes operation in 2 seconds. Then, during cycles when a pump out is called for, the pump motor drains the water tank for the time determined by the pump-out timer. The pump- out timer also acts in place of the harvest timer during cycles with a pump out.

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

Dip Switch Setting		Time (seconds)
No. 3	No. 4	T1	T2
OFF	OFF	10	150
ON	OFF	10	180
OFF	ON	10	120
ON	ON	20	180

T1: Time to drain the water tank

T2: Harvest timer at pump out

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