Installation
Air Exhaust Ventilation
WARNING
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 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.
3. Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.

FIRE AND EXPLOSION HAZARD
Be sure to read FIRE OR EXPLOSION
HAZARD and TOXIC FLUID HAZARD on
page 4, 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. 6.
