longer than the factory setting may be advertised in cases where the drain provided at
harvest needs to be prolonged for extra cleaning. Before changing this setting, contact
Hoshizaki Technical Support at 1-800 233-1940 for recommendations. Keep in mind that
setting the harvest timer to a longer setting decreases 24-hour production.
Note that the pump-out timer (S1 dip switch 3 & 4) acts in place of the harvest timer
during cycles with a pump out. For details, see “III. C. 3. Pump-Out Timer (S1 dip switch
3 & 4).“
Note: On models with a pump-out every cycle, the harvest timer is only relevant during
the initial harvest cycle since a pump out occurs every cycle there after.

3. Pump-Out Timer (S1 dip switch 3 & 4)
The pump motor stops for 2 seconds, then allowing the pump motor and drain valve to
energize. Water is removed from the bottom of the water tank and sent down the drain.
The pump-out 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 set, and generally no adjustment is required. The pump-
out timer control can be set to pump-out for 10 or 20 seconds.

4. 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.
