Installation
Install the System
FIG. 1. shows a typical electrostatic air spray system. It
is not an actual system design. For assistance in
designing a system to suit your particular needs, contact
your Graco distributor.
Warning Sign
Mount warning signs in the spray area where they can
easily be seen and read by all operators. An English
Warning Sign is provided with the gun.
Ventilate the Spray Booth
Electrically interlock the gun air supply with the ventila-
tors to prevent gun operation without ventilating fans
operating. Check and follow all National, State, and
Local codes regarding air exhaust velocity require-
ments.
High velocity air exhaust will decrease the operating effi-
ciency of the electrostatic system. Air exhaust velocity of
100 ft/min (31 linear meters/minute) should be sufficient.
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.
• Be sure your installation complies with National,
State and Local codes for the installation of elec-
trical apparatus in a Class I, Div. I, Group D or a
Group II, Category 2G Hazardous Location.
• Comply with all applicable local, state, and
national fire, electrical, and other safety regula-
tions.
Provide fresh air ventilation to avoid the buildup of
flammable or toxic vapors when spraying, flushing,
or cleaning the gun. Do not operate the gun unless
ventilation fans are operating.
