INSTALLATION
Be sure that all operators read and understand this entire
manual and the separate manuals supplied with compo-
nents and accessories before using this equipment.
Reference numbers and letters in parentheses refer to
the Typical Installation drawing, Figs. 1-4, and the parts
drawings and lists on pages 14-17.
Accessories mentioned are available from your Graco
distributor (see page 18). If you supply your own acces-
sories, be sure they are adequately sized to meet your
system’s requirements.
The Typical Installation above is only an example. For
assistance in designing a system to meet your particular
needs, contact your Graco representative or Graco
Technical Assistance (see back page).
PUMP INSTALLATION
Refer to page 7 to install pump Model 222-268, for use
in cold spray systems.
Refer to page 8 to install pump Model 221-123, for use
in heated spray systems, or to convert pump
Model
222-268 to a heated system.
To convert pump Model 222-268 to a heated unit, order
the following:

SYSTEM ACCESSORIES
Install an air line filter (A) in the main air line (B), to re-
move harmful dirt and moisture from the compressed air
supply. To provide automatic lubrication of the air motor,
install an air line lubricator (C) downstream from the
bleed-type master air valve (17).
Install a second bleed valve (F) in the main air line, to iso-
late the accessories for servicing.
The bleed-type master air valve (17) and the fluid
drain valve (13) are
supplied with your pump, to help
reduce the risk of serious bodily injury including fluid
injection, splashing in the eyes or on the skin, or injury
from moving parts if you are adjusting or repairing the
pump.
The
bleed-type master air valve relieves air trapped
between this valve and the pump after the air is shut
off. Trapped air can cause the pump to cycle unex-
pectedly. The valve is located downstream from the
air regulator.
The
fluid drain valve assists in relieving fluid pressure
in the displacement pump, hose, and gun; triggering
the gun to relieve pressure may not be sufficient.
