Operation
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 Proce-
dure
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 4.
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 secure-
ly. Retorque all fasteners before start-up.
3.
Place the suction tube (if used) in the fluid to be pumped.
4.
Place the end of the outlet hose into an appropriate con-
tainer.
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
.
Warning
To reduce the risk of serious injury whenever you are
instructed to relieve pressure, always follow the
Pressure
Relief Procedure
