General Information
D Fig. 2 shows a wall mounted HVLP spray applica-
tion. It is only a guide for selecting and installing
system components. Contact your Graco distributor
for assistance in planning a system to suit your
needs.
D Always use Genuine Graco Parts and Accessories,
available from your Graco distributor. If you supply
your own accessories, be sure they are adequately
sized and pressure rated for your system.
D Use a compatible, liquid thread sealant on all male
threads. Tighten all connections firmly to avoid air
or fluid leaks.
NOTE: On all npt threads, tighten to 2–3 turns past
finger tight.
D Reference numbers and letters in parentheses refer
to the callouts in the figures and the parts lists on
pages 23–22.

the first time, check and retorque all external fas-
teners.
