Connect the High Voltage Power Supply
The electrical connections to the Power Supply (H)
must be performed by a qualified electrician, in accor-
dance with all applicable local, state and national codes.
Connect the High Voltage Cable
Grease the resistor tube as described in Resistor Tube
Regreasing on page 13.
Route the High Voltage Cable (M) from the gun to the
Power Supply. Lubricate o-rings with petroleum jelly.
Connect the High Voltage Cable to the Power Supply.
To avoid permanent indentations of the cable and cable
failures due to unnecessary stress to the cable, follow
these steps:
1.
Support the cable overhead to keep people from
walking on it and vehicles driving over it.
2.
DO NOT clamp the cable too tightly at supports.
3.
Avoid sharp kinks and bends in the cable.
Check the Electrical Grounding (See Fig
1)
...------WARNING - - - - - - - .
Proper electrical grounding of every part of your
system is essential. For your safety, read the warn-
ing section, FIRE OR EXPLOSION HAZARD, on
page 3. Ground the system as explained there.
Then check your system as explained below.
1.
Make sure the High Voltage Power Supply is pro-
perly grounded and located outside the spray area.
The Power Supply case and spray gun actuator
can become charged if the case is not well
grounded. The ground wire is part of the high
voltage circuit and must, without fail, be con-
nected to a true earth ground. As an added
precaution, attach a separate ground wire to the
case of the High Voltage Power Supply.
2.
Shut off the Power Supply and the air and fluid lines
to the gun.
3.
Have a qualified electrician check the electrical
grounding continuity of the spray gun. Use an ohm-
meter
(X)
to measure resistance between the ac-
tuator of the gun
(Y)
and a true earth ground
(Z).
The resistance should be less than 20 ohms.
...------WARNING - - - - - - - ,
If the resistance is over 20 ohms, the gun is not
property grounded, and the system may be hazar-
dous. Check again that you have properly ground-
ed your system components; see FIRE OR EX-
PLOSION HAZARD, on page
3.
Since the gun is
grounded through connection to an undamaged,
properly grounded, high voltage cable (which is
grounded through connection to a properly
grounded power supply), check for a grounding
problem with the cable and power supply first. BE
SURE you have corrected the problem before us-
ing the system.
Mount the Spray Gun
Mount the gun
(Q)
on a stationary support or on a
reciprocating arm. The mounting rod must be properly
grounded.
Mount the gun head 254 to 300 mm (10 to 12 in.) from
the workpiece.

Connect the Air Lines (Refer to the Typical
Installation Drawing)
1.
Install an air line filter (B) to ensure a clean, dry air
supply to the gun. Dirt and moisture in the line can
ruin the appearance of your finished piece, and
cause malfunction of the Power Supply.
2.
Install an air line lubricator (C) as close to the pump
(D) as possible.
3.
Install a normally closed, 3-way air solenoid (P), or
hand valve in the air supply line (A).
4.
Install an air regulator (E) on the pump and gun air
supply lines to control air pressure to pump and
gun.
5.
Install a bleed-type air shutoff valve (G) on the main
air line and each gun air supply line to shut off air to
the pump and/ or gun(s). Install an additional bleed-
type valve on each pump air supply line to relieve air
trapped between this valve and the pump after the
air regulator is shut off. See Bleed-Type Air
Shutoff Valve and Fluid Drain Valve Required,
warnings section, page 3.
6.
Connect the atomizing air line
(U
from the air line to
the gun's 114 npt(f) atomizing air inlet. Refer to the
Typical Installation drawing .
7.
Connect the cylinder air line (V) from the solenoid
valve to the gun's
1/4
npt(f) cylinder air inlet.
Adjust the Air Bleed Valve (See Fig
2)
If the gun is mounted above the workpiece, remove the
plug (11), adjust the air bleed valve (43) to allow slightly
more atomizing air through the front of the gun, then
replace the plug (11), This helps prevent fluid from drip-
ping from the front of the gun onto the workpiece.
