Installation
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). 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.
