having a container ready to catch the drainage.
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the pump
thoroughly with a compatible solvent. Follow the steps
under Starting and Adjusting the Pump.

Operation

1. Be sure the pump is properly grounded. Read FIRE
AND EXPLOSION HAZARD on page 3.
2. Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant or PTFE tape
on all male threads. Tighten the fluid inlet and outlet
fittings snugly. Do not overtighten the fittings into the
pump.
3. Place the suction tube (if used) in the fluid to be
pumped.
4. Place the end of the fluid hose (N) into an appropriate
container. Close the fluid drain valve (J).
5. With the pump air regulator (H) closed, open all
bleed-type master air valves (B, E).
6. If the fluid hose has a dispensing device, hold it open
while continuing with the following step. Slowly open
the air regulator (H) until the pump starts to cycle.
Allow the pump to cycle slowly until all air is pushed
out of the lines and the pump is primed.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air
regulator. Remove the suction tube from the solvent
and place it in the fluid to be pumped.
Pump Shutdown
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
At the end of the work shift, relieve the pressure.
