Important Safety Information Explanation Polarization–This means that the larger slot must be neutral and the small slot must be at line voltage. Mispolarized–The outlet is incorrectly wires so that the larger slot is at line voltage and the smaller slot is neutral. Grounded–This means the round hole connection is connected to earth ground through a connection to the main power panel. Ungrounded–The round hole connection is not complete to earth ground and/or the main power panel.

General Information is important to understand that water pressure is the operation force in the water valve. HOW IT WORKS When the valve operating solenoid is energized, a magnetic field is produced that lifts the plunger away from the pressure release hole in the center of the diaphragm. The pressure in the guide tube area is released through the hole allowing the inlet pressure to lift the diaphragm off of the outlet seat. Water flows under the diaphragm and out through the valve outlet.
General Information DRIVE MOTOR When the water level/pressure switch is satisfied circuits are completed to the main drive motor. The drive motor is a special high torque split-phase, four pole motor. Two windings are used. The run winding is designed for full time use in wash and spin. A second winding, called the auxiliary or “start” winding is used to provide starting torque and determine direction of rotation.
