Air Exhaust Ventilation
.
To provide a remote exhaust:
1. Remove the muffler (U) from the pump air exhaust
port (K).
2. Install a grounded air exhaust hose (S) and connect
the muffler (U) to the other end of the hose. Use
muffler PN 111897, sold separately. The minimum
size for the air exhaust hose is 1 in. (25 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 (T) at the end of the air exhaust
line to catch fluid in case a diaphragm ruptures. If
the diaphragm ruptures, the fluid being pumped will
exhaust with the air.
If pumping flammable or toxic fluids, you must vent the
exhaust away from people, animals, food handling
areas, and all sources of ignition. Follow all applicable
codes.
NOTICE
The air exhaust port is 1 npt. Do not restrict the air
exhaust port. Excessive exhaust restriction can
cause erratic pump operation and poor diaphragm
life.
