Operation
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 fluid and moving
parts, follow the Pressure Relief Procedure when you
stop dispensing and before cleaning, checking, or
servicing the equipment.
1. Close the pump air regulator (C) and the bleed-type
master air valve (E) (required in the system).
2. Hold a metal part of the dispensing valve firmly to a
grounded metal container and trigger the dispense
valve to relieve pressure.
3. Open the drain valve (N).
Start the Pump
To determine the fluid output pressure using the air
regulator reading, the output fluid pressure equals the
air pressure shown on the regulator gauge.
Regulate air to the pump so that no air line or fluid line
component or accessory is over pressurized,
1. Turn the air regulator (C) to the minimum setting.
2. Direct the outlet hose into a waste container.
3. Open the bleed-type master air valve (E).
4. Slowly adjust the air regulator (C) until the pump is
running smoothly and all air has been pumped out
of the pump and hoses. If the pump contains
solvent, be sure to pump it all into the waste
container.
5. Use the air regulator (C) to control the pump speed
and cycle rate. Always use the lowest pressure
needed to obtain the desired results. This results in
optimum system efficiency and reduces pump
wear.

NOTICE
Never allow the pump to run dry of the fluid being
pumped. A dry pump quickly accelerates to a high
speed, possibly damaging itself, and it may get very
hot.
NOTE: The pump only takes a few strokes to prime.
However, in a large system, it may take several minutes
to completely prime the fluid lines.
NOTE: Use a low-level cutoff valve at the pump intake
to prevent air from being sucked into the pump and
fluid lines if the supply container runs dry. A 1-1/2 npt(f)
thread connection low level cutoff is available (Part No.
203688).
