User manual WHIRLPOOL WRF532SMBB DIMENSION GUIDE

[. . . ] 3 Parts lists and wiring diagrams are in the center of this manual, printed on yellow paper. September, 1993 Page 1 WRF532SMBB SPECIFICATIONS Always refer to the nameplate, located on the back of the cabinet, for the: · model number, · serial number, · basic electrical requirements, · minimum circuit ampacity, · maximum fuse size, · and refrigerant charge. A serial number plate with the model number, serial number and refrigerant charge is located behind the front panel, below the control box. The unit comes from the factory with the correct refrigerant charge contained in the receiver. The refrigerant charge information is for recharging, should that be necessary. [. . . ] Timer - Timer & Switch Assembly The timer begins to turn when activated by the cube size control. The outer surface, or large diameter lobe of the timer cam, determines the length of time for finish freezing of the ice cubes, while the inner surface, or small diameter lobe, determines length of the harvest cycle. The single-pole, double throw microswitch on the timer controls the power to the plug in relay coil, making it either the freezing or harvest cycle. The microswitch is actuated by a cam assembly directly connected to the timer motor. The timer cam can be adjusted to vary the defrost time, as required. One complete rotation of the cam will take eight minutes. Harvest is preset at 2 and a quarter minutes. Hot Gas Solenoid Valve The hot gas solenoid valve opens only during the harvest cycle. When it opens, it diverts the hot discharge gases so that they flow directly into the evaporator plates, by-passing the condenser and thermostatic expansion valve. The hot gases warm the evaporators, releasing the ice cubes from the ice cube molds. The hot gas solenoid valve is installed in a branch of the discharge line from the compressor, and when the timer switches the ice machine into the harvest cycle, the energized solenoid coil lifts the valve stem within the valve body, allowing the hot discharge gas to be diverted to the evaporators. High Pressure Safety Switch: Contacts open at 400 P. S. I. G. Bin or Ice Level Control Maximum Full Height : 8" from the base of the ice machine. Partial Fill Setting: 21" - 22" from the base of the ice machine. Maximum Storage Bin Interior Height: 8' from the base of the ice machine. OPERATING CHARACTERISTICS The values listed below are representative of values seen at a wide range of air and water temperatures and are for a normal cube size. Temperatures are Condenser/ Ambient Air/ Water FREEZE CYCLE Average Discharge Pressure at Average Temp. Suction pressure at the end of the freeze cycle Freeze Time 275-210 P. S. I. G. 13-15 minutes HARVEST CYCLE Average Discharge Pressure 175 P. S. I. G. Average Suction Pressure Lo Temp (0/70/55) 75-80 P. S. I. G. Harvest time is assumed to be 2. 25 minutes. This can be adjusted to suit local conditions. This unit uses R-22. If the nameplate lists a different quantity of refrigerant, go by the nameplate.
