OPERATION

Pressure Relief Procedure
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury
from splashing.
1. Shut off the air supply to the pump.
2. Open the dispensing valve, if used.
3. Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.
Sanitize the pump before first use
The pump was tested before leaving the factory.
Residue of the testing water can be left in the
pump. To avoid contamination, flush the pump
before first use. It is the user's responsibility to
properly sanitize the pump before first use.
Starting and adjusting the pump
1. Be sure the pump is properly grounded. See
page 8 for proper grounding.
2. Check fittings to be sure they are tight. Tighten
fluid inlet and outlet fittings 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 the fluid hose into an
appropriate container.
5. Close the fluid drain valve.
6. Back out the air regulator knob and open all
bleed-type master air valves.
7. Slowly increase air pressure with the air regulator
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. Trapped air can cause
the pump to cycle unexpectedly, which could
result in serious injury from splashing.
8. If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses.
9. Close the bleed-type master air valve.

At the end of the work shift and before you check,
adjust, clean or repair the system, follow Pressure
relief procedure page 10.
Special precautions
1. When medium is left in the pump chambers his
can generate chemical reactions when pumping
another fluid. Always flush pumps with a neutral
fluid before changing from medium.
2. Take care liquids left in the pump chamber can't
freeze, this can damage the pump.
3. It is possible to run the pumps on nitrogen gas
instead of compressed air. Take care about
sufficient ventilation around the pump as the
exhaust of the pump will put nitrogen gas in the
atmosphere.
4. Using the pump submerged: It is necessary
to connect the air outlet of the pump to the
atmosphere be using a flexible hose, to prevent
liquid to enter the air side of the pump. Take in
consideration, all external parts of the pump
must be 100% resistance to the medium where
the pump is placed in. Special care have to been
taken the pump standing 100% vertical and
can't to float in all circumstances.
5. In case of big changes in temperature while
operating, it is necessary to control the tension
on the bolts carefully. Sudden big temperature
shocks can cause over on under tightening of
the pump and will lead to leaks and/or damage
the pump.
