1.2. Descripción
Main Features of the Machine
 18/8 stainless steel housing
 Powerful speed reducer (24Kg./m. @ 7 rpm.)
 Copper evaporator on precision bored tubing (HB 50)
 Durable stainless steel auger with resilient coating
 Ice drops out of the bottom of unit
 Speed reducer in top part of the unit
 Ecological refrigerant R404a
1.3. Principio de funcionamiento
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. 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.
