Ventilate the Spray Booth

WARNING
To prevent hazardous concentrations of toxic
and/or flammable vapors, spray only in a properly
ventilated spray booth. The High Voltage Power
Supply must be electrically interlocked with the
ventilators to prevent operation of the power
supply unless the ventilation fans are operating.
NEVER OPERATE THE SPRAY GUN UNLESS
VENTILATION FANS ARE OPERATING.
Check and follow all of the National, State and
Local codes regarding air exhaust velocity
requirements.
Check and follow all local safety and fire codes and
OSHA standard 1910–107(b)(5)(i).
NOTE: High velocity air exhaust will decrease the
operating efficiency of the electrostatic system.
Air exhaust velocity of 100–150 ft/min (31–46
linear meters/minute) should be sufficient.

Connect the High Voltage Cable

Typical Installation Drawing)
1. Connect one end of the High Voltage Cable (N) to the
gun (Q) in the spray booth area.
2. Insert the High Voltage Cable into the insulator tube
of the gun and tighten the cable with the retaining nut.
3. Route the High Voltage cable (N) from the gun to the
Power Supply (K). To avoid permanent indentations
of the cable and cable failures caused by unneces-
sary stress to the cable, be sure to take the following
precautions:
a. Support the cable overhead to avoid people
walking on it and vehicles driving over it.
b. DO NOT clamp the cable too tightly at supports.
c. Avoid sharp kinks and bends in the cable.
4. Lubricate the cable o–rings with petroleum jelly. At-
tach the cable to the Power Supply.

Connect the Air Lines

Installation Drawing)
1. Install an air line filter (M) to ensure a clean, dry air
supply to the gun. Dirt and moisture in the air line can
ruin the appearance of your finished work piece, and
cause the Power Supply to malfunction.
INSTALLATION

2. Install an air line lubricator (D) as close to the pump
(F) as possible.
3. Install a bleed–type air regulator (E) on the pump and
gun air supply lines to control air pressure to the
pump and gun.
4. Install a bleed–type air shutoff valve (S) on the main
air line and each gun air supply line to shut off air to
the gun(s). Install an additional bleed–type valve on
each pump air supply line.
WARNING
The bleed–type air shutoff valve is required in your
system to relieve air trapped between this valve
and the pump after the valve is closed. Trapped air
can cause the pump to cycle unexpectedly, which
could result in serious bodily injury, including
splashing in the eyes or on the skin and injury from
moving parts.
5. Connect an air supply line to the 1/4 npt(m) IN port on
the Power Supply air flow switch.
6. Connect an air line from the 1/4 npt(m) OUT port on
the air flow switch to the gun's 1/4 npsm(m) air inlet.

Connect the Fluid Line

Installation Drawing)
1. Before connecting the fluid line (P), blow it out with
air, and flush it with solvent. Be sure the solvent you
use is compatible with the fluid to be sprayed.
2. Connect the fluid line from the outlet of the pump to
the 3/8 npsm(f) inlet of the gun.
3. Install a fluid filter (G) and drain valve (T) at the pump
outlet.
WARNING
The fluid drain valve is required in your system to
assist in relieving
displacement pump, hose and gun; triggering the
gun to relieve pressure may not be sufficient.
Install a drain valve close to the pump's fluid outlet.
The drain valve reduces the risk of property
damage or serious bodily injury, including
splashing in the eyes or on the skin and
contamination from hazardous fluids.
4. Install a fluid regulator (O) to control the fluid pres-
sure to the gun.
