8) Close door (for undercounter models) / Replace the front panel in its place (for modular models).
9) Verify that after the final cycle, the frost on the aspiration pipe is at 20 mm (0.78 in) of the compressor.
10) For modular models: Verify the ice slab with the pictures below. In case the thickness sensor needs to be
regulated, rotate the thickness adjustment screw CW to increase bridge thickness. Rotate CCW to decrease bridge
thickness.
For undercounter models adjust the cycle thermostat.
Too Big Just Right
Damages due to the lack of maintenance and cleaning operations are not included on the warranty.
(3) Sequence of Operation
FOR UNDERCOUNTER MODELS:
Initial Start-up: It's recommended that the first time the machine is started (or the water tray has been emptied) it
begins with the harvest sequence to ensure the water tray is filled.
Freeze sequence: The compressor is energized. The timer G2 de-energizes the hot gas valve, so the evaporator begins
to freeze. The timer G2 energizes the water pump so the water circulates from the water tray to the upper distributor,
flowing through each cube cell, where it freezes.
Harvest sequence: The compressor will continue energized. The timer G2 energizes the hot gas valve during a certain
time. The timer G3 at the same time energizes the water inlet valve during a certain time to fill the water tray with the
appropriate quantity of water. The ice slab slides off the evaporator and into the bin. After this, the freeze sequence
starts again.
When storage bin is full the stock thermostat detects a low temperature and the machine shuts off at the end of the
freeze sequence. The ice machine remains off until enough ice has been removed from the storage bin and the stock
thermostat doesn't detect this low temperature.
FOR MODULAR MODELS:
Initial Start-up: The pump and the drain electrovalve are energized during 30 seconds to empty the water tray
preventing the scale build-up in water. Then the pump and the drain electrovalve are de-energized, and the water inlet
valve is energized filling the water tray until the water level sensor detects the water reaches the appropriate level.
Then the freeze sequence starts.
Freeze sequence: The compressor is energized and the water pump is energized after 30 seconds. The water inlet
valve is also energized at the same time that the water pump to replenish water level and then de-energized. The
compressor and water pump will continue energized until the thickness sensor detects the thickness of the ice slab is
the appropriate. Then the harvest sequence starts.
