Air Exhaust Ventilation
If pumping 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 in. npt(f). Do not restrict the air exhaust port. Excessive exhaust restriction can cause erratic pump operation.
Installation
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 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 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.
