Warning
FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings and
precautions regarding TOXIC FLUID
HAZARD, and FIRE OR EXPLOSION
HAZARD on page 3, 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
handling areas, and all sources of ignition when pumping
flammable or hazardous fluids.
Diaphragm failure will cause the fluid being pumped to ex-
haust 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 ex-
haust port. Excessive exhaust restriction can cause erratic
pump operation.
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 19 mm ID. If a
hose longer than 4.57 m is required, use a larger diame-
ter 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.
