Installation
Prepare the Site
NOTE: Always use Genuine Graco Parts and Acces -
sories, available from your Graco distributor . If you
supply your own accessories, be sure they are ade -
quately sized and pressure rated for your system.
Bring a compressed air supply line from the air com -
pressor to the pump location. Be sure all air hoses are
properly sized and pressure-rated for your system.
Use only electrically conductive hoses.
Before installing any air line components, blow out the
air lines to remove scale and other debris. Use pipe
compound or tape sparingly and only on male threads.
WARNING
A bleed-type master air valve is required in your
system. Install the valve downstream from the air
regulator . This valve relieves air trapped between it
and the pump when the valve is closed, to help
reduce the risk of serious injury , including fluid
injection and splashing of fluid in the eyes or on the
skin, and injury from moving parts if you are adjust -
ing or repairing the pump.
Install the Regulator
The air regulator controls pump speed and outlet
pressure by adjusting the air pressure to the pump.
Locate the regulator as close as possible to the equip -
ment it serves, but upstream from the pump’ s bleed-
type master air valve. Install the regulator in the air line
so the air flow is in the direction of the arrow stamped
on the body .
Panel nuts are included with the regulators, for use in
wall mountings.
