Air Exhaust Ventilation
WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read FIRE OR EXPLOSION
HAZARD and TOXIC FLUID 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
exhaust with the air. Place an appropriate container at
the end of the air exhaust line to catch the fluid. See Fig.

The air exhaust port is 3/8 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To exhaust to a remote location:
1. Remove the muffler (W) from the pump air exhaust
port.
2. Install an electrically conductive air exhaust hose (X)
and connect the muffler to the other end of the hose.
The minimum size for the air exhaust hose is 3/8 in.
(10 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 (Z) at the end of the air exhaust line
to catch fluid in case a diaphragm ruptures. See Fig.
