e) Harvest Pump Timer (S4 dip switch 7)

NOTICE

Factory set for proper operation. Do not adjust. Adjustment outside of the factory default setting may result in damage to the icemaker.

Depending on the harvest pump timer setting, the pump motor either stays off or is energized the last 50 seconds of harvest. When the pump motor is energized, water circulates over the evaporator. The harvest water valve is open during harvest for a maximum of 6 minutes or the length of harvest minus 0 or 50 seconds (determined by the harvest pump timer setting), whichever is shorter.

When S4 dip switch 7 is in the on position and harvest begins, X10 relay energizes and allows the harvest water valve, X12, and X13 relays to energize. A lockout circuit is created using the X10, X12, and X13 relays. This prevents the drain valve from energizing during harvest pump timer. See "III.B. Wiring Diagram."

50 seconds before harvest termination, LED 4 goes off de‑energizing WV2 (harvest water valve) and X12 relay. X13 relay remains energized through the holding circuit through X10 and X13 relays. Next, LED 3 on the control board turns on and X11 relay energizes, allowing the pump motor to energize. The pump motor is energized the last 50 seconds of harvest.

f) Factory Use (S4 dip switch 8)

Factory set for proper operation. Do not adjust. This must be left in the factory default position.

g) Freeze Timer (S4 dip switch 9 & 10)

NOTICE

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 freeze timer, the control board initiates the harvest cycle. After 2 consecutive freeze timer terminations, the control board shuts down the icemaker. In this case, see "IV.F.3. Low Ice Production" for possible solutions.

The freeze timer is factory set, and generally no adjustment is required. Before changing this setting, contact your local Hoshizaki distributor or Hoshizaki Technical Support for recommendations.
