Connect the Air and Fluid Lines

FIG. 3. shows a schematic of air and fluid line connec- tions, and FIG. 5. shows the manifold connections. Con- nect the air and fluid lines as instructed.

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 Grounded Air

Supply Hose.

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.
