ple, animals, food handling areas,
and all sourc
es of ignition. Follow all applicable
codes.

2. Install a grounded air exhaust hose (S) and
connect the muffler to the other end of the hose.
The minimum size for the air exhaust hose is 1
in. (26 mm) ID. If a hose longer than 15 ft (4.57
m) is required, use a larger diameter hose. Avoid

line to catch fluid in case a diaphragm ruptures.
If the diaphragm ruptures, the fluid being pumped
will exhaust with the air.
