[a] EVAPORATOR (CASING)

The Evaporator consists of a stainless steel icemaking cylinder coiled with a refrigeration
pipe and wrapped together with a polyurethane foam insulation material. Water coming
from the inlet into the Evaporator will be frozen into ice. The Ice Spout is located on top of
the Evaporator. The Deicing Heater (Belt Heater) around the top of the cylinder functions to
reduce the load on the Gear Motor (FM-481AGE-HCN, FM-300AFE-HCN only). See "5.
REFRIGERATION CIRCUIT" for further details.

[b] AUGER

The stainless steel Auger is supported by the upper and lower Bearings of the Evaporator
and slowly rotated by the Gear Motor, while scraping off the ice forming on the inner wall of
the Cylinder and pushing up to the Ice Spout.
