HARVEST MODE

Electrical System

When the water level in the reservoir drops below the water level sensor it signals the electronic control to terminate power to the condenser fan, and then the water recirculating pump. The reservoir drain pump is activated to fully drain the reservoir. Power is then sup- plied to the hot gas valve and a fill request is sent to the measured fill valve. The fill valve fills to the requested volume while the hot gas valve is energized for the balance of the har- vest mode.

If the evaporator thermistor is unplugged, the evaporator defaults to a timed 4 minute har- vest.

If the water level sensor is disconnected or open, the control defaults to 25 minutes of freeze time. The cleaning indicator LED fea- ture will not function if the water level sensor is disconnected.

Refrigeration System

The hot gas valve opens, allowing high pres- sure refrigerant gas to bypass the condenser, and flow through the condenser accumulating tube. The hot gas pushes the liquid refrigerant that has accumulated in the accumulator tube up into the evaporator. The hot liquid refrigerant evenly heats the evaporator plate so that the ice slab releases quickly and evenly.

The ice slab, when released, slides off of the evaporator plate onto the cutter grid.

Water System

The electronic control board sends a signal to the water valve. The signal tells the water valve how much water to be filled, allowing water to flow into the water reservoir pan. The water fill volume is determined by the ice thickness setting.

As a result of the hot gas flow and the ice sliding off the evaporator plate, the evaporator tem- perature begins to rise. When the evaporator thermistor reaches the set temperature (52°F), the unit switches to the Freeze mode. This cy- cling between Freeze and Harvest, continues until the ice bin is full.

The electronic control board operates the vari- ous components and systems in the ice maker for each of the Freeze and Harvest modes.

CLEAN MODE

Electrical System

The electronic control board operates the various components and systems during the Clean mode.

For the order of the components cycled, see the flow chart on page 6-13.

Water System

When the service control switch is in the “Clean” position, the water recirculating pump circulates the cleaning solution that has been added to the reservoir, up to the water distributor, across the evaporator, and back into the reservoir, where it is recirculated. The compressor and hot gas valve operate to heat the evaporator.

DIAGNOSTIC MODE

1.Do not continue with the diagnosis of the ice maker if a fuse is blown, a circuit breaker is tripped, or if there is less than a 120 volt power supply at the wall outlet.

2.All units that have failed during the first few days of use should be checked for loose connections or miswiring.

Entering and Navigating — Manual Diagnostics

•Turn the product on. Within 10 seconds of Power On, press and hold the On and the Clean buttons. Release both buttons when all user interface LEDs begin to flash.

•Within 5 seconds of all LEDs flashing, push any other button on the user interface. This begins manual diagnostics.

•If no button is pressed within 5 seconds, the product goes into the automatic diagnostic mode used at the assembly plant. Each component is cycled for 5 seconds.

•The Service button (or Off button on some models) is used to advance through each step.

•To exit manual diagnostics, press the Power button (or On button on some models)
