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.
If the muffler (P) is installed directly to the air exhaust
pot, apply PTFE thread tape or anti-seize thread lubri-
cant to the muffler threads before assembly.
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. See

WARNING
Read the FIRE AND EXPLOSION HAZARD and
TOXIC FLUID HAZARD warnings on page 5 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 flam-
mable 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
