FIRE AND EXPLOSION HAZARD
Be sure to read and follow the warnings and
precautions regarding TOXIC FLUID
HAZARD, 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 ex-
haust with the air. Place an appropriate 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 ex-
haust port. Excessive exhaust restriction can cause erratic
pump operation.
If the muffler (P) is installed directly to the air exhaust port,
apply PTFE thread tape or anti–seize thread lubricant to the
muffler threads before assembly.
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 19 mm ID. If a hose long-
er than 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.
