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 flashing or steady) and the start of the shutdown sequence. For dispenser
unit applications, the ice level at shutoff may need to be adjusted depending on the
dispenser agitation or dispense method. Increasing the shutdown delay setting allows for
a higher level of ice in the bin before the icemaker shuts down. For a typical dispenser
unit application, a 100-second shutdown delay is recommended. When used with a
standard Hoshizaki storage bin, any shutdown delay setting is acceptable.
Increasing the shutdown delay allows a higher level of ice in the dispensing
unit/storage bin before shutdown. This could lead to icemaker movement or ice
overflow.

c) Drain Frequency Control (S1 dip switch 4)

This unit is factory set for optimum performance with the 1-in-1 drain cycle (S1 dip
switch 4 in the "OFF" position). This setting allows for removal of sediment from the
evaporator without interrupting the icemaking process. An optional 1-in-12 drain cycle is
available.
d) Continuous Dispensing Timer (S1 dip switch 5 & 6)
DCM models only. The dispense mode switch on DCMs must be in the "CONTINUOUS"
position for this setting to apply. The factory setting allows ice to be dispensed
continuously as long as the dispense solenoid is activated.
