1.3. Operating principle
Water enters water trough via a float valve which provides a constant head of water. Through a
hole in the bottom of the trough, water flows into the bottom of the evaporator and floods it to
the same height as in the water trough. Water freezes upon contact with evaporator wall, and is
scraped off as ice by the vertical, rotating auger. Ice is carried upward until it passes through
discharge flap and falls into bin. When bin is full, automatic shut-off sensor (micro-switch on
discharge flap) switches off machine.
IMPORTANT!
If unit is placed on top of a cold room, and/or ice has to fall a long distance from unit, a
MECHANICAL ICE LEVEL SENSOR should be installed. (except 50 and 90)
To prevent ice from compressing in cold storage, we recommend transferring ice through a
plastic tube (80-100 mm diameter) attached to its lower end the DISPERSION CONE which is
PROVIDED WITH THE MACHINE in all models. (except 50 and 90).
