Installation
Install the System
FIG. 2. shows a typical electrostatic air-assisted spray
system, and F
IG. 3. shows possible system options. It is
not an actual system design. For assistance in design-
ing a system to suit your particular needs, contact your
Graco distributor.
Warning Signs
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 turbine air supply with the
ventilators 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. The minimum allow-
able air exhaust velocity is 60 ft/minute (19 linear
meters/minute).
