    4. SEQUENCE 1) When the water supply tap is opened and the unit Evaporator is energized, the compressor starts and the tilting motor (synchronous motor-1) operates to move the tray into the horizontal position. Meanwhile the water valve opens to supply ice making water into the tray. When the tray reaches the horizontal, the water valve closes to start a freeze cycle.
  • Page 31 4) As the unit repeats the above freeze and defrost cycles, the storage bin is gradually filled with ice. When ice reaches a certain level, a tilt of the tray Bin Control moves the bin control activator at the bottom of the Switch tray to operate the bin control switch [*4] so that the ice making mechanism will stop.
