Graco 24H689 Instructions Manual page 5

NOTE: To prevent damage to pump, remove sediment
from the bottom of the container before installing a
pump on an existing container.
The maximum working pressure of each component in your
system may not be the same. To reduce the risk of
over-pressurizing any part of your system, which may result
in component rupture, fire or explosion and cause serious
bodily injury, be sure you know the maximum working
pressure rating of each pump and its connected
components.
•
Never exceed the maximum working pressure of the low-
est rated component connected to a particular pump.
•
Be sure you know the maximum working pressure of
each component.
•
Do not exceed the maximum pump cycle rate.
•
Regulate air pressure to prevent over pressurization at
fluid section of the pump.
•
Regulate air pressure to the pump so that no fluid line
component or accessory is over pressurized.
Air Line and Accessories
NOTICE
Do not hang the air accessories directly on the air inlet.
Mount them on brackets. Always use a flexible hose
between all connections. The air inlet is not strong enough
to support accessories and may cause one or more to
break.
Use thread sealant on all male threads except
•
swivel connections.
• Install a pump runaway valve to shut off the air to
the pump if the pump accelerates beyond the
pre-adjusted setting. A pump that runs too fast can
be seriously damaged.
• Install the air regulator (8) to control pump speed
and pressure.
For NPT models order Graco Part No. 24H420 or for
BSP models order Graco Part No. 24H419.
• Install a bleed-type master air valve (7) upstream
from pump air regulator (8) but within easy reach.
For NPT models order Graco Part No. 110223 or for
BSP models order Graco Part No. 125041.
• On the main air supply line from the compressor,
install an air line filter to remove harmful dirt and
contaminants from the compressor air supply.
