System System Requirements
The use of multiple guns with one isolation cabinet
may cause electric shock, fire, or explosion. To
help prevent injury or equipment damage, use only
one gun per isolation cabinet.
A Graco voltage isolation system must have the
following features:
• An isolation enclosure that prevents persons from
making contact with the high voltage components
before the system voltage is discharged. All
components of the isolation system that are
charged to high voltage must be contained within
the enclosure.
• A bleed resistor to drain off the system voltage
when the spray gun is not in use. A metal part of
the fluid supply unit must be electrically connected
to the bleed resistor.
• A safety interlock that automatically discharges the
system voltage when anyone opens the isolation
enclosure.
NOTICE
NOTICE NOTICE
The system should not have any severe arcing
occurring when the isolation mechanism opens
and closes. Severe arcing will shorten the life of
the system components.
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.
Warning

Warning Sign

Warning Sign Sign
Mount warning signs in the spray area where they

Installing and servicing this equipment requires
access to parts which may cause electric shock
or other serious injury if work is not performed
properly.
• Do not install or service this equipment unless
you are trained and qualified.
• Comply with all local codes and regulations.
Fig. 12 (Typical Installation) shows a typical
electrostatic air-assisted spray system. It is not an
actual system design. For assistance in designing
a system to suit your particular needs, contact your
Graco distributor.
Ventilate the the Spray Spray Booth
Ventilate Ventilate the Spray
Do not operate the gun unless ventilating air flow is
above the minimum required value. Provide fresh
air ventilation to avoid the buildup of flammable or
toxic vapors when spraying, flushing, or cleaning
the gun. Interlock the gun air and fluid supply
to prevent operation unless ventilating air flow is
above the minimum required value.
The spray booth must have a ventilation system.
Electrically interlock the gun air and fluid supply with
the ventilators to prevent gun operation any time that
the ventilation air flow falls below minimum values.
Check and follow all local codes and regulations
regarding air exhaust velocity requirements. Verify
the operation of the interlock at least once a year.
