timer is factory set, and generally no adjustment is required. However, a setting
longer than the factory setting may be advised 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)
When a pump-out is called for, the pump motor stops for 2 seconds, then the pump
motor and drain valve 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. 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.
