Changing the Orientation of the Fluid Inlet
and Outlet Ports
The pump is shipped with the ports facing the same
direction. To re-orientate the ports into any position:
1. Remove the clamps (130) holding the inlet and/or
outlet tee to the elbows.
2. Rotate the manifold tee (339) and reattach. Install
the clamps (130) and tighten handtight.
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 (P) from the pump air exhaust
port. See F
IG . 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 F
IG . 5.

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 F
IG . 5.
