 Place the hose barb fitting on top of the
centering ring.
 Secure the fitting with the clamp.
 On rotary vane pumps only, 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.
Fill the pump with oil so the level is
between the lines on the sight gauge on the end of the pump housing.
 Verify that the vacuum pump voltage setting agrees with the Concentrator voltage
shown on the serial number label.
 Turn the vacuum pump power switch ON. (Rotary Vane or Diaphragm pumps)
 For rotary vane
pumps, set the
gas ballast to
closed or
minimum
position.
