2. "G" Control Board with Harvest Pump Timer Operation
1 to 3-min. harvest timer in
control (S4 dip switch 1 & 2)
• Maximum inlet water valve time: 6 min. or the length of
harvest minus 50 sec. (S4 dip switch 7), whichever is shorter.
• Maximum harvest time: 20 min.
FS check
Legend:
Comp–compressor
FM–fan motor
FMR–fan motor-remote
FS–oat switch
HGV–hot gas valve
LLV–liquid line valve
MBC–mechanical bin control
PM–pump motor
WV–inlet water valve
Components Energized when the Control Switch is in the "WASH" Position
The "WASH" position on the control switch is used when cleaning and sanitizing the icemaker. When in the "WASH" position, power is
supplied to the pump motor. With the cleaning valve closed, the cleaner and sanitizer ow over the outside of the evaporator plate assembly.
With the cleaning valve open, the cleaner and sanitizer ow over both the outside and the inside of the evaporator plate assembly.
Note: Close the cleaning valve after cleaning and sanitizing are complete, otherwise the icemaker will not restart when the control switch is
placed in the "ICE" position.
