OPERATING INSTRUCTIONS
A temperature sensing control bulb located in the storage hopper starts and stops the ice making process in
response to ice level in the hopper. With this ice level control “calling” for ice (hopper ice level is low), ice begins
to form on the stainless steel tubing coils in the evaporator coils until it contacts the ice thickness probe (low
voltage conductivity sensor). At this point, the conductivity probe triggers the harvest timer motor. The harvest
timer contains five (5) cam operated switches which function as detailed in the table on the following pages.
Table 3. HARVEST CYCLE
Time Cam Switch Action
0--86 Seconds #1 Timer motor energized
1--23 Seconds ±1 Second #4 Water dump valve open
1--37 Seconds ± 2 Seconds #2 Hot gas solenoid valve open.
Air pump off.
Condenser fan motor off.
37--90 Seconds #2 Air pump on.
Condenser fan motor on.
Hot gas solenoid valve closed.
36--39 Seconds #3 Harvest motor on.
43--47 Seconds #5 Hopper agitator motor operates.
When ice contacts the ice lever control bulb in the storage hopper, the control will shut down the refrigeration
system. If this signal occurs during the harvest cycle, the harvest cycle will be completed before shutdown oc-
curs.
To dispense ice, push the lever located on the lower front panel. Ice will flow from the ice chute until the lever is
released.
For units with a built-in cold plate, ice will automatically fill the cold plate cabinet. Allow one (1) hour for the cold
plate to reach its maximum capacity. Start up the beverage system and adjust the faucets to the proper brix.
Pushing the lever on any faucet will provide beverage of the appropriate flow.
