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 using. This may include disassembly and
inspection of the wetted components. The pump was
tested in an NSF registered lubricant with incidental
food contact rating (H1). Remove compound by wiping
or washing, leaving surfaces free of any substance that
could be transferred to food being processed. Flush the
pump thoroughly with a compatible cleaning solution or
disassemble and inspect. Follow the steps under Start-
ing and Adjusting the Pump or the Service section.
Starting and Adjusting the Pump
1.
Be sure the pump is properly grounded. Refer to
Grounding on page 4.
2.
Check fittings to be sure they are tight. Use a com-
patible liquid thread sealant on male threads.
Tighten fluid inlet and outlet fittings securely.
3.
Place the suction tube (if used) in fluid to be
pumped.
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.
When you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air reg-
ulator. Remove the suction tube from the cleaning solu-
tion and place it in the fluid to be pumped.
WARNING
Read the PRESSURIZED EQUIPMENT HAZARD
warnings on page 4.
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:
•
are instructed to relieve pressure
•
stop pumping
•
check, clean or service any system equipment
WARNING
Read the TOXIC FLUID HAZARD warnings on page 5
Never move or lift a pump under pressure. If dropped,
the fluid section may rupture. Always follow the Pres-
sure Relief Procedure before lifting the pump.
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 inef-
ficient pump operation.
