Connect the Waterborne Fluid Hose
Always use a Graco waterborne fluid hose between
the voltage isolation system fluid outlet and the gun
fluid inlet.
Before connecting the waterborne fluid hose to the
gun, blow it out with air and flush with water to
remove contaminants. Flush the gun before using it.
To reduce the risk of electric shock, install only
one continuous Graco waterborne hose between
the isolated fluid supply and the gun. Do not splice
hoses together.
1. Remove the gun air inlet fitting (21).
Figure 10 Connect the Fluid Hose
2. Make sure the barrel fluid inlet is clean and dry.
Apply dielectric grease to the threads of the barrel
connector (101a) and screw it into the fluid inlet.
3. Apply dielectric grease to the threads of the
hose (101) and screw it into the barrel connector
(101a).
4. Align the bracket (B) holes with the air inlet and
exhaust outlet. Secure with the air inlet fitting
(21).
5. Press the exhaust tube (35) onto the exhaust
valve. Secure with the clamp (36).
6. Slide the other end of the hose through the hole
in the side of the isolated enclosure. Connect the
swivel (Z) to the fluid outlet of the pump. Secure
the hose to the side of the enclosure with the
bracket (W).
NOTE: The Graco warranty and approvals are
void if the electrostatic spray gun is connected
to a non-Graco voltage isolation system or if the
gun is operated above 60 kV.
