Pressure Relief Procedure
WARNING
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, follow this
procedure whenever you are instructed to relieve
pressure, when you shut off the pump, and before
you check, adjust, clean, move, or repair any system
equipment.
1. Shut off air and reserve air to the pump.
2. Open the dispensing valve if the system has one.
3. Open the fluid drain valve to relieve all system
pressure, and have a container ready to catch the
drainage.
Flushing the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush it thoroughly
with a compatible solvent. Follow the procedure in
Starting and Adjusting the Pump.
Starting and Adjusting the Pump
WARNING
To reduce the risk of serious injury, splashing in the
eyes or on the skin, and toxic fluid spills, never move
or lift a pump under pressure. If the pump is dropped,
the fluid section could rupture. Always follow the
Pressure Relief Procedure above before you move
or lift the pump.
1. Be sure the pump is properly grounded. Read and
follow the instructions in Grounding on page 5.
2. Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant on all male
threads. Tighten the fluid inlet and outlet fittings and
plugs securely. Retorque all fasteners before
start-up. See Torque Sequence, page 20.

Operation

3. Place the suction tube (if used) in the fluid to be
pumped.
4. Place the end of the outlet hose into an appropriate
container.
5. Close the fluid drain valve.
6. With the air regulator closed, open all bleed-type
master air valves.
7. If the outlet hose has a dispensing device, hold it
open while continuing with step 8.
8. Slowly open the air regulator until the pump starts to
cycle. Allow the pump to cycle until all air is pushed
out of the lines and the pump is primed.
NOTE: To prime a remote solenoid-operated air
valve, operate the pump at a minimum 60 cpm rate
until the pump is fully primed.
Pump Shutdown
At the end of the work shift, and before you check, adjust,
clean, or repair the system, relieve air and fluid
pressure.
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
