4. SEQUENCE OF OPERATION
Once you connect the machine there is a time delay of 140” during which the water valve is
activated to ensure the water tray is filled. Compressor, pump will be off.
Once the time is up, it continues with a harvest cycle and the compressor starts.
After the harvest, the ice production starts, so the pump starts working. The pump, recirculates
the water from the water tray to the upper nozzles (#2) distributor which provides a fan of water
that waters each ice cube row in the evaporator (#1), in which the water starts freezing and making
the ice.
When the temperature probe (#3) at the end of the evaporator reaches an adjusted value
Tc (-
12/-8°C)
, the fabrication continues the fixed time with the combination of dip-switches 1-4 (see
table). This way we can ensure the filling of the ICE CUBE is correct in different working
conditions.
Once the
production time is over the harvest phase starts. The pump stops, the hot gas and the
water inlet valves open. When the evaporator temperature probe (#3) reaches an adjusted value
