IG
F . 5. shows the manifold connections. Connect the air
IG
lines as instructed.
WARNING
Fire, Explosion, and Electric Shock Hazard
To reduce the risk of a fire, explosion, or
electric shock, the gun turbine air supply
must be interlocked with:
•The isolation system to shut off the turbine
air supply anytime the enclosure or
safety fence is opened.
•The ventilators to prevent operation of the
power supply unless the ventilating fans
are on.
WARNING
Electric Shock Hazard
To reduce the risk of electric shock or other
serious injury, you must use the red-colored
Graco grounded air hose for the turbine air
supply hose, and you must connect the hose ground
wire to a true earth ground. Do not use the black or
grey-colored Graco air hoses.
1. Connect the red-colored Graco Grounded Air Sup-
ply Hose (B) to the gun's turbine air inlet (TA) and
connect the hose ground wire (A) to a true earth
ground (N). The gun turbine air inlet fitting has
left-hand threads to prevent connecting another type
of air hose to the turbine air inlet. See Accessories
on page 56 for further information about the hose.
2. Check the electrical grounding of the gun as
instructed on page 19.
