WARNING
FIRE AND EXPLOSION HAZARD
Be sure to read FIRE AND 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 peo-
ple, 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. 8.
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 (W) from the pump air exhaust
port.
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.
See Fig. 8.
