EP-200 SERIES PUMP INSTALLATION, OPERATION AND SERVICE MANUAL

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 coun- terclockwise direction.

Pump discharge orientation and impeller rotation direction is viewed from the rear of the motor as shown in on Page 6, Figure 2. 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 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 pump 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.

•While tightening the screws that secure the pump scroll to the motor frame, periodically spin the impeller to be sure that adequete clearance is maintained between the impeller blades and the body of the pump scroll.
