Installation
Air Exhaust Ventilation
Diaphragm failure will cause the fluid being pumped to
exhaust with the air. Place an appropriate container at the
end of the air exhaust line to catch the fluid. See F
The air exhaust port is 3/4 npt(f). Do not restrict the air
exhaust port. Excessive exhaust restriction can cause
erratic pump operation.
If the muffler (P) is installed directly to the air exhaust port,
apply PTFE thread tape or anti–seize lubricant to the muffler
threads before assembly.
To provide a remote exhaust:
1.
Remove the muffler (P) from the pump air exhaust port.
2.
Install an electrically conductive air exhaust hose (T)
and connect the muffler (P) to the other end of the hose.
The minimum size for the air exhaust hose is 19 mm ID.
If a hose longer than 4.57 m is required, use a larger
diameter hose. Avoid sharp bends or kinks in the hose.
See F
3.
Place a container (U) at the end of the air exhaust line to
catch fluid in case a diaphragm ruptures.
