Installation

Connect the Wa

terborne 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).

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

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.
