Air Exhaust Ventilation
WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings
and precautions regarding TOXIC
FLUID HAZARD, and FIRE OR EXPLO-
SION HAZARD on page 3, before op-
erating 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 appropri-
ate 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.
To provide a remote exhaust:
1. Remove the muffler (P) from the pump air exhaust
port.
2. Install a grounded air exhaust hose (T) and con-
nect 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.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.
