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 is viewed from the rear of
the motor as shown in on Page 10, Figure 3. Note
that the pump scroll outlet must always be positioned
at the bottom horizontal position.

5.1.2 Attaching Pump Scroll
After determining the correct orientation of the pump
scroll outlet, attach the pump scroll to the pump

• In Box 1 of 2, locate the EP-300 Scroll/Inlet fas-
tener package containing hex nuts and washers.
• Place scroll assembly over impeller and align M8
screw stu
ds on the scroll assembly with the holes
on the frame. Place the scroll assembly onto the
pump frame. Be careful not to damage gasket.
• From the motor side of the vertical mounting plate
of the frame, place an M8 washer onto the M8
screw stud. Then thread the M8 hexnut onto the
M8 screw stud, finger tighten. Repeat for all 12
