FIG. 4 Orientation of Fluid Ports
Air Exhaust Ventilation
Be sure the system is properly ventilated for your type of installation. You must vent the exhaust to a safe place, away from people, animals, food handling areas, and all sources of ignition when pumping flam- mable or hazardous fluids.
Diaphragm failure can cause the fluid being pumped to exhaust with the air. Place an appropriate con- tainer at the end of the air exhaust line to catch the fluid. See FIG. 5.
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 (P) from the pump air exhaust port. See FIG. 5.
2.Install a grounded 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 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 grounded container (U) at the end of the air exhaust line to catch fluid in case of a diaphragm rupture. See FIG. 5.
