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.
1. Remove the muffler (T) from the pump air
exhaust port.
2. Install a grounded air exhaust hose (U) and
connect the muffler (T) 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 at the end of the air
exhaust line to catch fluid in case a dia-
phragm ruptures. Locate the container
away from all sources of ignition, including
pilot lights and waste materials. If the dia-
phragm ruptures, the fluid being pumped
will exhaust with the air.
Be sure to read and follow the TOXIC FLUID
OR FUMES HAZARD warnings, page 7, and
FIRE AND EXPLOSION HAZARD warnings,
page 5, before operating this pump. You must
vent the exhaust away from people, animals,
food handling areas, and all sources of igni-
tion when pumping flammable or hazardous
fluids. Vent in accordance with local codes, or
in the absence of local codes, an industry or
nationally recognized code having jurisdiction
over the specific installation.
