User manual WHIRLPOOL WRF535SWBB DIMENSION GUIDE

[. . . ] Always go by the nameplate. SPECIFICATIONS Model Number WRF535SWBBA-1A Dimensions H" X W" X D" W/out legs Cube Size Medium Basic Electrical 115/60/1 Max. Fuse Size 15 28. 56 X 18 X 20. 5 The finish is stainless steel with a galvanized back panel. Minimum circuit ampacity is used to determine wire size per national electric code. OPERATING REQUIREMENTS: MINIMUM MAXIMUM Air Temperature Water Temperature Water Pressure Voltage 500 F. [. . . ] When moved to the ON position, it makes a circuit to the compressor. When moved to the OFF position, the other components will still operate. High Temperature Cut Out This control senses the temperature of the discharge line and will open to stop the operation of the ice machine should the discharge temperature exceed the preset maximum (175oF). it must then be manually reset to restart the machine by pushing the button at the front of the control box. Water Pump The water pump operates during the freezing cycle only, pumping water through the spray nozzles into the inverted spray cups. Inlet Water Solenoid Valve The water solenoid valve, located in the back panel of the unit, is energized only during the harvest or cleaning cycles. When energized it allows a metered amount of water to flow into the machine (. 21 g. p. m. ) This water flows to the top of the evaporator and then down into the reservoir. June 2001 Page 7 WRF535SWBB Bin Thermostat Control The bin thermostat control body is located in front of the control box just beside the cube size control. The thermostat sensing tube is located in the ice storage bin on the left side wall where is automatically shuts the ice maker off when the bin is full and restarts when ice is removed. Factory settings are 1 degree C (36 degrees F) cut out and 4 degrees C (39 degrees F) cut in. It can be adjusted by turning the adjustment screw visible through the control box cover. Hot Gas Valve Assembly The hot gas valve assembly is comprised of two parts, the valve body and the coil. The vapor, now primarily a gas, goes through the suction line tube to the compressor where the cycle is repeated.

It is intended as a guideline only, and is based on data compiled from NEW CLEAN units. Allow a variation from each end of the range given. Refrigeration system pressures: High Side (discharge) End of Freeze cycle 125 - 130 psig Harvest cycle 83 - 125 psig Low side (suction) End of Freeze cycle 1 - 3 psig Harvest cycle (maximum) 120 psig C. Compressor amps Freeze cycle 4. 3 to 3. 6 Harvest cycle 3. 6 to 7. 7 ADJUSTMENT OF THE CUBE SIZE: Adjust only when cubes are too big or small. To increase the size, turn knob 1/8 turn clockwise. To make the cubes smaller, turn the knob 1/8 turn counterclockwise. Observe the size of the cubes in the next two harvest cycles, if more adjustment is needed, continue adjustments until the correct size is obtained. ADJUSTMENT OF THE BIN THERMOSTAT CONTROL Adjust the bin thermostat when the ice maker turns off too soon (ice level low) or when it turns off too late (ice storage bin overfills. ) To increase the ice level in the storage bin: (located under front panel on control box cover) clockwise one eight turn at a time until the ice level that the machine maintains is correct. To decrease the ice level in the storage bin: CORRECT SIZE ·Rotate the bin thermostat adjustment screw TOO SMALL, LITTLE OR NO ICE IN THE CENTER OF THE CUBE. ·Rotate the bin thermostat adjustment screw counterclockwise one eight turn at a time until the ice level is correct. TOO BIG, THICK BULGE OF SOLID ICE ON THE END. June 2001 Page 12 WRF535SWBB GRAPH OF SYSTEM PRESSURES This graph shows the system pressures during one full cycle at 90oF. water.
