Connect The Air And Fluid Lines - Graco PRO 5500hc Instructions Manual

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.
