Air Line and Accessories
NOTE: Install the air line accessories in the order shown
in the Typical Installation on page 7.
• Use thread sealant on all male threads except
swivel connections.
• Install a pump runaway valve (D) 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 (G) 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 (F) upstream
from the pump air regulator (G) but within easy
reach of the pump.
For NPT models order Graco Part No. 110223 or for
BSP models order Graco Part No. 125272.
• On the main air supply line from the compressor,
install an air line filter (H) to remove harmful dirt and
contaminants from the compressor air supply.
Follow Plate - Grease Models Only
For grease models only a follow plate is required for
pumping fluid from the drum. See page 12 for follow
plate installation instructions.
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.
