Installation
Step 3. Vacuum Pump Set Up
 Remove protective caps from inlet and outlet
ports.
 Some vacuum pumps have inlet fittings that
screw into the inlet port. Make sure the O-ring
is on the sealing surface. Insert fitting into the
pump housing and tighten securely.
 Some vacuum pumps have inlet fittings that
clamp to the pump. Place the centering ring
with filter screen on the inlet fitting.
 Place the hose barb fitting on top of the
centering ring.
 Secure the fitting with the clamp.
 Attach the exhaust filter to the exhaust port.
Some pumps have filters that screw in.
Others require that a centering ring is
placed on the fitting and then a clamp
secures it similar to the inlet fitting.
 NOTE: Rotary vane vacuum pumps
must have an exhaust filter to prevent
oil mist from exiting the pump and
depleting the oil supply.
