Installation

CAUTION: Risk of chemical overdose. Ensure pump does not overdose during backwash or periods of no flow.

CAUTION: Always wear protective clothing, face shield, safety glasses, and gloves.

CAUTION: Diagrams are for guideline purposes only. Consult an expert for specialized systems.

Mounting Location: Choose an area near the chemical supply tank, injection point, and electrical supply, where it can be easily serviced. Mount to a secure surface using enclosed hardware. Mount pump close to the injection point, keeping inlet and outlet tubing as short as possible. Keep suction lift height low.

A back flow prevention check valve is recommended at the injection point. Ensure check valve internals are kept clean.

Pressure regulator valves should NOT be used as back-flow prevention valves.

A pressure relief valve is recommended at the discharge to prevent excessive pressure.

An anti-syphon valve is not required. A ball-type shut-off valve is recommended on the discharge side prior to the injection point.
