WARNING
A safety fence(J), non-conductive hoses, isolation

to isolate the fluid in the fluid line (F), andfluid supply
unit (M) from ground
and toprevent people from contacting portions of the system that arecharged to
high voltage. This helps reduce therisk of electric
shock, which could
cause serious injury.

safetyfence as specified below. Anchor the fence
to the
floor as specified in Fig 2.
Safety Fence Specifications
1. The fence MUST provide at least a6 x 6 x 6 fl. (1.83 x
1.83 x 1.83 m) protective area. See Fig 1.
2. This area MUSTONLY be accessiblethrough asingle
gate. This gate MUSTbe hinged and latchedso it
only opens outwards.
3. The fence MUST be constructed so it can be bolted to
the floor and and can withstand any forces
induced
by vehicles, equipment, or personnel in the area,
without reducing theprotection provided. See Fig 2.
4. The fence MUST be constructed so there is no more
than 6 inches (152 mm) ofclearance between the
bottom of anyportion of the fence and the
building floor.

(64 mm) diameter spherical object from passing
through it.
6. The fence MUST be painted a high visibility yellow.
7. A means MUSTbe provided to connect the fenceto
true earth ground. There
must be electrical continuity
between all sides of the fence and the gate.

Install the Isolation Stand
1. Position theisolation stand inside the safety fence.
The isolation stand MUST be placed inthe center of
the fence so it is a minimum of 20 inches (508
mm)
from any side of the fence.
2. To help keep the stand from moving, install one
1/2 inch (13 mm) bolt inthe floor in the position of the
one hole inthe bottom of the isolation stand. Referto
Fig 2 and 3.
3. Place the isolation stand's bolt holeover thebolt in
the floor.

Install theStrain Relief/Ground Terminal
and Fluid Hose Assembly
Install theVoltage Control
The voltage control (L) contains a bleed resistor, which
continually bleeds the current to ground, and a quickdump switch,which dumps the charge to ground whenever the safetyfence air-line interlock(G)is disconnected
to open the gate..
1. Place the voltage control 4 inches (1 02 mm) from
the
edge of the Isolation stand.
Two plates (312) are provided to relieve strain and ground
the fluid hose conductive hose layer. Theyalso function
as a grounding terminal
as shown in Fig 6, page 8.Mount
the plates, with the
fluid hose, to the side of the fence as
shown in Fig 5.
Connect the Fluid Hose to the Spray Gun
2. Measure the resistance between the isolation stand
grounding grate and the
voltage control ground. The
resistance shouldbe less than 20 ohms.
1. Remove the exhausttube (67) clamp and air fitting
(17) from the spraygun. Refer to page 36.
2.
3. Secure the voltage control to the floor with four 1/2
inch (13 mm) anchor bolts. See Fig 4.
Using petroleum jelly, lubricate O-ring (304) on the
hose barbed insert (301). Thenpush the hose barbed

against the shoulder of the
barbed insert (301).
3. Tighten thefitting (302) until the O-ring on the fitting is
compressed to about halfits original thickness.
4. Tighten the nut (305) against the
fitting (302).
5. Align the bracket(309) holes with the air inlet andex-
haust outlet, and secure the bracket with the air
fitting (17) and exhaust tube (67)clamp.
NOTE: The fluid hose (306) consists of an insulated layer, a conductive layer, and an abrasion-resistant
outer layer. Theconductive layer is connected to
ground at the strain

CAUTION
Methylene chloride is not recommended as a
flushing or cleaning solvent with this gun or any
other devicewith nyloncomponents.
Do not use any cleaning method which may allow solvent intothe gun air passages. Clogged
air passages causepoor atomization and excessive current demands. Point the gun down while
