NOTICE
Do not expose the air motor to temperatures
higher than 120°F (49°C) or the immersed fluid
pump to temperatures higher than 250°F (121°C).
Excessive temperatures may damage the pump
packings and seals.
To avoid injury from exhaust hose whip, never
operate the pump without a muffler installed.
Secure the exhaust hose to a solid, stationary
object.
Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop dispensing and before
cleaning, checking, or servicing the equipment.
1. Shut off the air supply to the pump.
2. Close the bleed-type master air valve (required
in system).
3. Open the fluid ball valve and/or dispensing valve
to relieve fluid pressure.
4. Open all fluid drain valves in the system, having
a waste container ready to catch drainage.
Leave drain valve(s) open until you are ready to
dispense again.
Flush Before First Use
The sanitary
pump was assembled using sanitary
lubricant on
moving parts and was tested in
water. Flus
h the pump thoroughly with an
appropriat
e cleaning solution or disassemble and
sanitize th
e parts before using the pump. See
Flushing Pr
ocedure, page 10. Check national, state,
and local co
des for specific limitations.
Adjusting the Pump Speed and
Pressure
Set pressure regulator to 0 psi. Open the bleed-type
master air valve. Adjust the pump air regulator until
the pump is running smoothly.
Allow th
e pump to cycle slowly until all air is pushed
outofth
e lines (the fluid will flow in a steady stream
from the
fluid outlet) and the pump is primed.
With the air supply turned on, the pump will start
when the dispensing valve is opened and stall
against pressure when the valve is closed. In a
circulating system, the pump operates until the air
supply is turned off.
NOTIC
E
Never allow the pump to run dry of fluid. A dry
pump will accelerate to a high speed, possibly
damaging itself.
If the pump accelerates quickly, or is running too
fast, stop the pump immediately and check the fluid
supply. If the supply is empty and air has been
pumped into the lines, replace the container and
prime the pump and lines with fluid. Be sure to
eliminate all air from the system.
