Air Exhaust Ventilation
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 (T) from the pump air exhaust
port.
2. Install a grounded air exhaust hose (U) and connect
the muffler (T) 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.
3. Place a container 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.
