SECTION 5: PUMP INSTALLATION
5.1 Pump Assembly Instructions
5.1.1 Determine Orientation of Pump Discharge
To ensure your safety, and comply with the terms of
the warranty, all units must be installed in accor-
dance with these instructions.
The pump must be installed in a location that it is
readily accessible for servicing.
An arrow is affixed to the outside of the pump scroll to
indicate the direction of rotation of the impeller. The
standard rotation of the impeller is in the counter-
clockwise direction.
Pump discharge orientation and impeller rotation
direction is viewed from the rear of the motor as
shown on Page 8, Figure 3. Note that the pump scroll
outlet must always be positioned at the bottom hori-
zontal position.

After determining the correct orientation of the pump
scroll outlet, attach the pump scroll to the pump
frame as follows:
• Place Flat Washer (P/N 95211600), on the 5/16" x
7/8" Screw (P/N 94273914).
• From the motor side of the vertical mounting plate
of the pu
mp frame, insert the 5/16" x 7/8" screws.
• Install two pieces of the gasket material on the
exposed thread ends of the mounting screws.
Make sure the ends of the opposing gasket seg-
ments interlock to form a complete circular
gasket.
• Carefully position the pump scroll against the ver-
tical mounting plate of the pump frame; align and
loosely install the 5/16" x 7/8" screws into the cor-
responding mounting holes in the pump scroll.
