PUMP MOTOR

A separate pump/pump motor is used to drain the wash tub.

Pump Motor

The pump motor is 120 VAC and is attached directly to the pump. The pump has a cleanout filter located at the front that allows for the removal of large objects that may have passed from the basket.

ECO VALVE

The washer has a specially designed floating (ball) valve that closes during the wash portion of the cycle so that 100% of the water and detergent mixture is used on the wash load. The Eco Valve insures that no water or deter- gent is wasted.

SUSPENSION SYSTEM

The wash tub is held in position with four shock absorbers attached to the bottom four corners of the tub assembly. In addition, the wash tub is suspended from the top frame of the washer with two springs attached to the sides of the unit.

Stability for this suspension system is provided by three concrete counterweights. Two are located at the front of the wash tub. One is positioned at the back of the tub. These coun- terweights eliminate the need for the traditional balance ring.
