Connect The Air And Fluid Lines To The Gun Manifold - Graco PRO AA5500sc unicarb Instruction Manual

Connect the Air and Fluid Lines
to the Gun Manifold
See Fig. 1 and 2, page 9, 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
(BB) to the gun turbine air inlet and connect the hose
ground wire (AA) to a true earth ground. See Fig. 1,
page 9. Check the electrical grounding of the gun as
instructed on page 15.
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.

Fluid Line
Before connecting the fluid line to the gun, 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)
CYL Cylinder Air Inlet Fitting
Connect a 1/4 inch O.D. tube between this fitting and
the solenoid. For quicker trigger response, use the
shortest hose length possible.

page 13.
KV kV Switch Air Inlet Fitting
Connect a 1/4 inch O.D. tube between the fitting and
the air solenoid.
P1 Fluid Supply Inlet Fitting
Connect a 1/4 inch npsm swivel fitting between the
fitting and the fluid supply.
TA Turbine Air Inlet Fitting
Connect the Graco Electrically Conductive Air Hose
between this fitting (left-hand thread) and the solenoid.
