Waste Receiver Evacuation Systems, or General Fluid
Transfer Applications (See Fig. 3)
1. Connect the suction hose (F) to the waste oil receiver
(M) with a fluid quick coupler (G).
2. Be sure the drain valve (C) is closed.
3. Connect the air hose (J) to the pump with an air line
quick coupler (B). A 90° elbow (134) is supplied for
use in wall mount applications.
4. Open the air regulator (A) until the pump starts to
cycle.
5. Adjust the air regulator. Do not use higher air
pressure than needed for the pump to provide good
suction. Increasing the pump cycle rate does not
necessarily improve suction.
Gear Oil Evacuation Systems (See Fig. 2)
1. Attach an appropriate wand (E) to the suction hose
(F).
2. Be sure the air inlet restrictor (125) is attached to the
pump.
3. Be sure the drain valve (C) is closed.
4. Connect the air hose (J) to the pump with an air line
quick coupler (B).
5. Open and set the air regulator (A) between 40 and 50
psi (280–340 kPa, 2.8–3.4 bar), adjusting for best
operation.
Operation
6. Place the suction wand (E) in the differential or fluid to
be pumped.
7. Pull the control valve (D) handle down to start the
pump.
8. Adjust the air regulator. Do not use higher air
pressure than needed for the pump to provide good
suction. Increasing the pump cycle rate does not
improve suction.
9. Push the control valve (D) handle up when finished.
NOTE: Be sure the control valve handle is closed when
the evacuation is completed. Failure to close it may
prevent other service bays on the line from developing full
suction.
Pump Shutdown
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 10.
At the end of the work shift, relieve the pressure.
