Always use a Graco waterborne fluid hose between
the voltage isolation system fluid outlet and the gun
fluid inlet. The waterborne fluid hose (101) consists
of an inner PTFE tube (T) and an abrasion-resistant
outer jacket (J). Shielded hose 24M732 also has
a conductive layer (C), The conductive layer is
connected to ground at the gun fitting bracket (104).
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.

Remove the gun air inlet fitting (21).
NOTE:
NOTE:
NOTE: In a shielded hose system, if a hose
failure occurs where high voltage arcs through
the inner tube, voltage will be discharged to
ground through the conductive hose layer. When
properly installed, the conductive hose layer is
grounded through its connection to the grounded
enclosure.
Using unshielded fluid hoses minimizes the
system capacitance, resulting in faster response
times and a large reduction in the energy stored
in the system, as compared to shielded hoses.
However, without the ground shield, a weak
static charge can occasionally build up on the
outer surface of the hose. To minimize any
static charge felt on the hose surface, bundle
the air and fluid hose together, and wrap with a
protective cover, as shown.
