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 (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

IG. 4 Venting Exhaust Air
Read the FIRE AND EXPLOSION HAZARD and
TOXIC FLUID OR FUMES HAZARD warnings on page
5 before operating this pump.
Be sure the system is properly ventilated for your type
of installation. When pumping flammable or hazardous
fluids, you must vent the exhaust to a safe place, away
from people, animals, food handling areas, and all
sources of ignition.
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

IG. 4.
