Page 30: [A] Evaporator (Casing)
[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. -
Page 31: [H] Belt Heater (Provided On Nugget Type)
[h] BELT HEATER (provided on nugget type) 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. -
Page 32: [K] Bin Control Switch
[k] BIN CONTROL SWITCH The bin control switch is composed of a reed switch attached to the spout and an actuator (ice detector) provided inside the spout and chute. The bin control switch operates as follows: 1. Ice reaches up to the ice detector. 2. -

V. REMOVAL AND REPLACEMENT 1. SERVICE FOR REFRIGERANT LINES [a] SERVICE INFORMATION 1) Treatment for Refrigerant Leak [R744] If a refrigerant leak occurs from an icemaker, ice production will be reduced. A continuous refrigerant leak will eventually cause an icemaker protector to trip to stop the icemaker. In case of a refrigerant leak, stop the icemaker and turn off the solenoid valve. -
Page 52: [B] Evacuation And Recharge
[b] EVACUATION AND RECHARGE 1) Attach a charging hose of a gauge manifold to a vacuum pump and the access valve of EPR (to be fitted by service personnel for self-contained type). 2) Open the low-side valve on the gauge manifold, and turn on the vacuum pump. 3) Allow the vacuum pump to pull down to a 760 mmHg vacuum. -
Page 53: Evaporator Assembly
7) Check for leaks using nitrogen gas (10 bar) and soap bubbles. 8) Evacuate the system (See “1. [b] EVACUATION AND RECHARGE”). 9) Attach the coil to the E.E.V. Be sure to secure the coil properly. 10) Refit the front panel in its correct position. 11) Connect the power source. - Page 54 EVAPORATOR Note: Skip the following steps 12) through 18) when the evaporator does not need replacement. 12) Recover the refrigerant and store it in a proper container, if required by an applicable law. IMPORTANT Always install a new drier every time the sealed refrigeration system is opened. Do not replace the drier until after all other repair or replacement has been made.
- Page 55 GEAR MOTOR 22) Cut the connectors. 23) Remove the three socket head cap screws securing the gear motor. 24) Assemble the removed parts in the reverse order of which they were removed. WARNING Be careful not to scratch the surface of the O-ring, or it may cause water leaks. Handle the mechanical seal with care not to scratch nor to contaminate its contact surface.
