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 anti-
siphon 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 foot valve/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 .25in. (6.3 mm) diameter in the shelf as shown in the dimension drawing (Figure F).
Attach pump securely using four #10 bolts and nuts.
