Part Number 80-1230-9 10/10 105OperationIce Making Sequence of OperationQF0400/QC0700/QF0800Ice Making Sequence of OperationPRIOR TO START-UPWhen the toggle switch is placed in the “ice” positionthe following must occur prior to starting an ice makingcycle.• The bin level probe must be open (bin level lightoff). If the probe is closed, (bin level light on) whenthe toggle switch is moved to ICE, the controlsystem waits until the bin level probe opens, (binlevel light off) before starting an ice makingsequence. If the bin level probe is removed/disconnected the ice machine will not start.• The water level probe must be closed (waterlevel light on) to start the compressor. If the waterlevel probe is open, (water level light off) thecontrol system waits until the water level probecloses before starting the compressor.INITIAL START-UP1A. FLUSHImmediately after placing the toggle switch into ICE,the dump valve solenoid, and gearbox are energized.After 45 seconds the dump valve de-energizes.1B. WATER FILLAfter 45 seconds the water float valve solenoid isenergized.2. FREEZE CYCLEWhen water contacts the water level probe, thecompressor and condenser fan motor energize(condenser fan motor is wired through a fan cyclingcontrol). The gear motor, compressor, condenser fanmotor and water float valve solenoid remain energizedas the ice machine makes ice. The water float valvewill open and close automatically to maintain theproper water level.
