Drive motor Turning the adjustment to the left, counterclockwise, will increase the rate the pressure in the evaporator. When the compressor is not running the valve will remain closed as the low side pressure will be high The evaporator drum drive motor is a single phase enough to close the expansion valve. motor of 1/2 HP wired for 220 Volts 60 Hz ­ 2. 1 Amps - 1400 R.

Evaporator Drum IMPORTANT Make sure that drive motor Refrigerant inlet/outlet takes place on left side rotates clockwise facing the unit's front. Failure to this, may result in wrong rotation of evaporator drum with the risk of major damages to The drum body is covered by a jacket in special stainless steel resistant to the water corrosion. Water failure Switch This switch used as safety device when low or interrupted supply water conditions are encountered. Operates on pressure between supply line and feed line to water reservoir. Ice Spout Safety Switch Located on top of the Ice Spout, the Safety Switch is operated by a plate on top of the ice chute by the ice backing up in the spout. [. . . ] Be sure of proper position and condition of plexiglass chute on spout opening. WRX988SIBW & MAR2000 Cleaning Instruction 1. Lock the float valve adjusting screw to avoid water incoming during the operation of machine. Make sure that during cleaning no ice will be stored in any bin or cooling room in order to avoid any kind of contamination by cleaning solution. Dump the contents from the drum basin by withdrawing drain plug located at the bottom refrigerant side of the evaporator. [. . . ]
