Installation
Air Exhaust Ventilation
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 (U) from the pump air exhaust
port.
2.
Install a grounded air exhaust hose (W) and connect
the muffler (U) 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 (X) at the end of the air exhaust line
to catch fluid in case a diaphragm ruptures. See Fig.
5. Locate the container away from all sources of
ignition, including pilot lights and waste materials. If
the diaphragm ruptures, the fluid being pumped will
exhaust with the air.

WARNING
Be sure to read and follow the TOXIC FLUID HAZARD
and FIRE AND EXPLOSION HAZARD warnings 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 area, 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.
5.
