Installation

2. Installing the pump assembly (refer to Figure 5):

NOTE: The pump assembly is packaged inside washer-extractor basket.

a. Remove the pump assembly from packaging and place at the rear of the washer-extractor resting flat on floor.

b.Route the two pump motor cable connections to the WSS control housing (Figure 8). Slide cable connectors in and twist to lock. Pump cables and receptacles are marked “PA” and “PB”. Refer to Figure 7.

c.Install large manifold hose clamp at the rear of washer-extractor and tighten. Refer to Figure 5.

d.Check ball valve for closed position. Before operating machine, ball valve must be closed.

NOTE: Pump rotation must be counterclockwise when pump is viewed from fan end or clockwise when viewed from plastic pump head end.

Improper rotation will cause the pump to fail, resulting in increased cycle time. Refer to rotation arrow decal on pump and Figure 5. Rotation may be corrected by exchanging two 3-phase power wires on the load side of the respective contactor, located in the remote-mounted WSS control module.

3. Installing pump hose and vacuum vents:

NOTE: Pump hoses and vacuum vents are packaged inside washer-extractor basket.

a. Remove pump hoses and four small hose clamps from packaging.

b.Slide on the pump hose to the appropriate pump (top pump to right tank, bottom pump to left tank as viewed from rear) and tank elbow at the rear of each tank. Refer to Figure 5. Tighten the small hose clamps.

c.Apply Teflon tape to vacuum vent threads and screw into top of each tank, tightening by hand only.

d.Secure the two pump hoses and the two pump motor cables with wire ties to frame side legs.
