Air Exhaust Ventilation
FIRE AND EXPLOSION HAZARD
Be sure to read
FIRE OR EXPLOSION
HAZARD
and
TOXIC FLUID HAZARD
on page 3, 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 appropri-
ate container at the end of the air exhaust line to
catch the fluid. See Fig. 3.
WARNING
The air exhaust port is 3/8 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
To exhaust to a remote location:
1. Remove the muffler (11) from the pump air
exhaust port.
PRESSURIZED EQUIPMENT HAZARD
To reduce the risk of serious eye injury
from ice particles,
never
operate the
pump with the air exhaust port open. Ice
may form during pump operation, and ice particles
will be ejected from the port along with the exhaust
air. If the muffler (11) is removed,
always
connect
an air exhaust hose to the exhaust port.
WARNING
2. Install an electrically conductive air exhaust hose
(X) and connect the muffler to the other end of the
hose. The minimum size for the air exhaust hose
is 3/8 in. (10 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 (Z) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures. If
the fluid is flammable, ground the container. See
Fig. 3.

VENTING EXHAUST AIR
(Submerged Installation Shown)
In a submerged installation (as shown), all wetted and non-wetted
pump parts must be compatible with the fluid being pumped.
