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 dia-
phragm ruptures. If the diaphragm rup-
tures, the fluid being pumped will exhaust
with the air.
