2. Installing the pump assembly (refer to Figure 5):
NOTE: The pump assembly is packaged inside
washer-extractor basket.

and place at the rear of the washer-extractor
resting flat on floor.

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.

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.
