Be sure to read and follow the warnings and precautions regarding T

and

FIRE OR EXPLOSION

HAZARD

on page 5, before operating

this pump.

Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handl- ing areas, and all sources of ignition when pumping flammable or hazardous fluids.

Diaphragm failure will cause the fluid being pumped to exhaust with the air. Place an appropriate container at the end of the air exhaust line to catch the fluid. See Fig. 6.

The air exhaust port is 3/4 npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.

If the muffler (P) is installed directly to the air exhaust port, apply PTFE thread tape or anti- seize thread lubricant to the muffler threads before assembly.

To provide a remote exhaust:

1.

Remove the muffler (P) from the pump air exhaust port.

2.

Install an electrically conductive air exhaust hose (T) and connect the muffler (P) to the other end of the hose. The minimum size for the air exhaust hose is

3/4 in. (19 mm) ID. If a hose longer than 15 ft

(4.57 m) is required, use a larger diameter hose.

Avoid sharp bends or kinks in the hose. See Fig. 6.

3.

Place a container (U) at the end of the air exhaust line to catch fluid in case a diaphragm ruptures.
