Connect the Air and Fluid
Lines
FIG. 3. shows a schematic of air and fluid line connec-
tions, and F
IG. 5. shows the manifold connections. Con-
nect the air and fluid lines as instructed.
1. Connect the Graco Grounded Turbine Air Supply
Hose (B) to the gun's turbine air inlet (TA) and con-
nect the hose ground wire (A) to a true earth ground
(N). The gun turbine air inlet fitting has a left-hand
thread to prevent connecting another type of air
hose to the turbine air inlet. See Accessories on
page 52 for further information about the hose.
2. Check the electrical grounding of the gun as
instructed on page 16.
3. Before connecting the fluid line (P1), blow it out with
air and flush it with solvent. Use solvent which is
compatible with the fluid to be sprayed.
