FIRE AND EXPLOSION HAZARD;
HAZARDOUS FLUIDS
Be sure to read and follow the warnings
and precautions regarding
HAZ-
ARDOUS FLUIDS,
and
FIRE OR
EXPLOSION 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. 5.
WARNING
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 con-
nect 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. See Fig. 5.
3.
Place a container (U) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures.
