ELECTRICAL WIRING INSTRUCTIONS FOR SilentFlo 5000

Refer to the following instructions to install an electrical cord / ground on a no-cord SilentFlo 5000:

1. Remove the end cap of the new SilentFlo 5000 pump by removing the two slotted screws on the rear black panel.
2. Insert the stripped ends of the cord through the rubber gasket on the end cap.
3. Connect the ground wire (green) to grounding lug located on the body of the pump.
4. The other two wires should be installed into the terminal block. The pump is not affected by the polarity of the incoming power, so either wire can be installed in either terminal. NOTE: Insure that excess wire does not protrude from the rear of the terminal block. Excessive wire will cause direct shorts.
5. After the wires are secure, reinstall the end cap using the two slotted screws.
6. If an exterior grounding wire exists, you must attach the exterior grounding lug with single screw (provided in kit). Then attach exterior grounding wire to exterior grounding lug.
