Operation
Pressure Relief Procedure
1.
Shut off the air to the pump.
2.
Open the dispensing valve, if used.
3.
Open the fluid drain valve to relieve fluid pressure,
having a container ready to catch the drainage.
Sanitize the Pump Before First Use
It is the user’s responsibility to properly sanitize the
pump before first use. It is up to the user whether this
will include disassembling and cleaning individual parts
or simply flushing pump with a sanitizing solution. As
necessary, follow the steps under
at right, under the
section on
on page 13.
Starting and Adjusting the Pump
1.
Be sure the pump is properly grounded. Refer to
on page 7.
2.
Check connections to be sure they are tight. Tighten
fluid inlet and outlet connections securely.
3.
Place the suction tube (if used) in fluid to be
pumped.
NOTE:
If fluid inlet pressure to the pump is more than
25% of outlet working pressure, the ball check valves
will not close fast enough, resulting in inefficient pump
operation.
4.
Place the end of fluid hose (L) into an appropriate
container.
5.
Close the fluid drain valve (J).
6.
Back out the air regulator (C) knob, and open all
bleed-type master air valves (B, E).
7.
If the fluid hose has a dispensing device, hold it
open while continuing with the following step.
8.
Slowly increase air pressure with the air regulator
(C) 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.
Pump Shutdown
At the end of the work shift, relieve pressure.
The equipment stays pressurized until pressure is
manually relieved. To reduce the risk of serious
injury from pressurized fluid or splashing fluid,
follow this procedure whenever you stop pumping
and before cleaning, checking, or servicing
equipment.
Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the
before
lifting the pump.
