2. BC1 (Infrared Sensor) Shutdown Delay (S1 dip switch 1, 2, 3)
Infrared sensor shutdown delay is the delay between the infrared sensor detecting ice
(infrared sensor yellow LED ashing 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-sec. shutdown delay is recommended.
When used with a standard Hoshizaki ice storage bin, any shutdown delay setting is
acceptable. WARNING!Increasing the shutdown delay allows a higher level of ice
in the dispenser unit/ice storage bin before shutdown. This could lead to icemaker
movement or ice overow.

3. 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.
