3 B. Sequence of Operation The steps in the sequence are as outlined below. This unit utilizes a control board to switch the components on and off as needed. When power is supplied, the power switch is in the "ON" position, and the control switch is in the "ICE" position, CB "POWER OK" LED comes on.
4 (3) Manual Drain: Manual drain is used when servicing evaporator components and cleaning and sanitizing the unit. When the unit is making ice and the control switch is moved to the "DRAIN" position, there is a 3-second delay, then CR (X1 on CB) and Comp (LLV and SLV on MLH models) de-energize and the 5-minute ice purge timer begins.

8 2. Features a) Low Water Safety When the inlet water valve opens during ll and rell, a 90-second low water safety timer starts. Once the upper oat switch closes the 90-second low water safety timer terminates. If the upper oat switch remains open longer than 90 seconds, a 1-beep alarm sounds.
9 f) High Voltage and Low Voltage Cut-outs The maximum and minimum allowable supply voltages of this icemaker are limited by the high voltage (147Vac±5% or more) and low voltage (9Vac±5% or less) cut-outs.
30 3. Alarm Safeties a) Low Water Safety (1-beep alarm) (1) Fill Cycle: If upper oat switch remains open 90 seconds after the inlet water valve has energized, the control board sounds a 1-beep alarm every 5 seconds.
31 f) High Voltage (7-beep alarm) The maximum allowable supply voltage for this icemaker is limited by the high voltage cut-out. When high voltage (147.5Vac ±5% or more) is present, the "POWER OK" LED turns off and the control board shuts down the unit and sounds a 7-beep alarm every 5 seconds.
3 b) Infrared Sensor Shutdown Delay (S1 dip switch 1, 2, & 3) Infrared sensor shutdown delay is the delay between the infrared sensor detecting ice (yellow LED ashing or steady) and the start of the shutdown sequence.
33 e) Bin Control Selector (S1 dip switch 7) This unit is factory set for infrared sensor bin control operation. No adjustment is required. When used on a standard ice storage bin, the mechanical bin control may be used instead of the infrared sensor by moving S1 dip switch 7 to the off position.
34 D. Bin Control An infrared sensor is used to control the level of ice in the dispenser unit/ice storage bin (S1 dip switch 7 in the "ON" position). The infrared sensor is the primary bin control device. 0VDC powers the infrared sensor from the control board K6 connector.

46 f) Infrared Sensor Shutdown Ice lls storage bin to level of activating infrared sensor, infrared sensor yellow LED turns on (ashing or steady). Infrared sensor shutdown sequence begins. For further information, see "II.B.1.e) Shutdown Cycle.
47 g) Mechanical Bin Control Shutdown Ice lls the chute to the point of engaging the mechanical bin control. Dip Switch 7 "ON": The icemaker shuts down within 10 seconds of the mechanical bin control opening and a 9-beep alarm sounds. Dip Switch 7 "OFF": Hoshizaki ice storage bin applications only.
48 h) Low Water Safety During ll or rell, should the upper oat switch fail to close within 90 seconds after the water valve energizes, a 1-beep alarm sounds. The water valve remains open until the upper oat switch closes. If this occurs during rell, the icemaker cycles down.
49 i) High Pressure Switch If pressure on the refrigeration circuit high-side exceeds Hoshizaki specications, a high pressure switch activates. The control board then shuts down the unit until the high-side pressure returns to an acceptable level. See "II.
