[h] BELT HEATER (provided on some models)
The belt heater is provided to reduce the load of ice passing the extruding head during a
freeze cycle and to prevent vapor lock during a flush cycle.
[i] REMOVABLE FLANGE
The flange used to be welded on the evaporator to fix the spout. But sometimes the
extruding head applies excessive load on the evaporator to compress ice, resulting in
breaking the welded joints. To avoid the load, the flange has been changed to a separate
part to be secured together with the extruding head by using sealing bolts.
[j] SEALING BOLT
Sometimes the icemaking operation may produce white solids on the drip pan. They are
deposits of silica and calcium contents in the icemaking water leaking from the sealing bolt.
The bolt is provided with retaining and sealing functions, which may be reduced by the load
and vibration during a freeze cycle. Do not reuse a removed sealing bolt.
