Installation
Connect the Air and Fluid Lines
See Fig. 1 and 2, page 8, for a schematic of air and
fluid connections. Connect the air and fluid lines to the
gun manifold as instructed at right.
Graco Electrically Conductive Air Hose
WARNING
ELECTRIC SHOCK HAZARD
To reduce the risk of electric shock or
other serious injury, the air supply hose
must be electrically connected to a true
earth ground. Use Only Graco Electrically Con-
ductive Air Supply Hose.
Connect the Graco electrically conductive air hose (B)
to the gun turbine air inlet and connect the hose
ground wire (A) to a true earth ground. See Fig. 1,
page 8. Check the electrical grounding of the gun as
instructed on page 14.
NOTE: The hose and the gun have special left-hand
threads to prevent connecting another type of air hose
to the gun turbine air inlet.

Black Hose: standard hose, semi-conductive nylon core,
urethane outer
Grey Hose: more flexible (less durable) than black hose,
modified semi-conductive polyamide core, urethane cover
Red Hose: conductive SST wire braid for grounding, polyure-
thane tube and cover
Fluid Line
Before connecting the fluid line, blow it out with air and
flush it with solvent. Use solvent that is compatible with
the fluid being sprayed.
Manifold Connections (See Fig. 5)
A1
Atomization Air Inlet Fitting
Connect a 3/8 inch O.D. tube between the fitting and
the air supply.
