6. Freeze Timer (S1 dip switch 9 & 10)
Adjust to proper specification, or the icemaker may not operate correctly.
The freeze timer setting determines the maximum allowed freeze time to prevent
possible freeze-up issues. Upon termination of the freeze timer, the control board initiates
the harvest cycle or pump-out cycle. After 2 consecutive freeze timer terminations, the
control board shuts down the icemaker. In this case, see "II.H.3. Low Ice Production"
for possible solutions. The freeze timer is factory set and no adjustment is required.
Before changing this setting, contact Hoshizaki Technical Support at 1-800-233-1940 for
recommendations.
7. Pump-Out/Drain Selector (S2 dip switch 1)
The pump-out/drain selector setting determines whether the pump motor energizes
(pump-out) or stays off (drain) after a 2-second delay at the beginning of the pump-out
cycle or at shutdown. Regardless of the pump-out/drain selector setting, the drain valve
energizes after a 2-second delay at the beginning of the pump-out cycle or at shutdown.
When the pump-out/drain selector is set to pump-out, the pump motor takes water from
the tank and forces it through the drain valve and down the drain. When the pump-out/
drain selector is set to drain, water drains by gravity through the drain valve.
8. Harvest Promotion Control (S2 dip switch 2)
Do not adjust. These must be left in the factory default position or the icemaker will
not operate correctly.
When activated, this control promotes harvest of ice on the evaporator that is hard to
remove. If the harvest cycle exceeds 6 minutes, the pump motor starts to operate for a
maximum of 3 minutes.
