INSTALLATION, PIPING AND WIRING

The metering pump should be located in an area that allows convenient connections to both the chemical storage

tank and the point of injection. The pump is water resistant and dust proof by construction and can be used

outdoors, however do not operate submerged. Avoid continuous temperatures in excess of 40°C (104°F). To

do otherwise could result in damage to the pump.

MOUNTING

Typical mounting arrangements are shown in Figures B to E.

Important: Injection point must be higher than the top of the solution supply tank to prohibit

gravity feeding, unless a suitable backpressure is always present at the injection point.

Installation of an antisiphon valve will prohibit gravity feeding.

1. For wall or shelf mounting, refer to Figure E. Connect suction tubing to suction valve of chemical pump.

Suction valve is the lower valve. Tubing should be long enough so that the footvalve/strainer assembly

hangs about 1-2 inches (2.5 - 5 cm) above the bottom of chemical tank. To keep chemical from being

contaminated, the tank should have a cover.

2. Flooded suction mounting (installing the pump at the base of the chemical storage tank, Figure C) is the

most trouble free type of installation and is recommended for very low output requirements. Since the

suction tubing is filled with chemical, priming is accomplished quickly and the chance of losing prime is

reduced.

To mount pump, drill 4 holes of .25" (6.3 mm) diameter in the shelf as shown in the dimension drawing (Figure

F). Attach pump securely using four #10 bolts and nuts.
