Spraying Waterborne Fluids Electrostatically - Graco 333013B Instructions - Parts Manual

Introduction

Spraying Waterborne Fluids Electrostatically

This electrostatic air spray gun is designed to spray
only waterborne fluids which meet at least one of the
following flammability requirements:
FM, FMc Approved:
• Material does not sustain burning in accordance
with the Standard Test Method for Sustained Burn-
ing of Liquid Mixtures, ASTM D4206.
CE-EN 50059 Compliant:
• Materials which cannot be ignited, in any mixture
with air, by an energy source of less than 500 mJ.
When connected to a voltage isolation system, all of the
fluid in the spray gun, fluid hose, and isolated fluid sup-
ply is charged to high voltage, which means that the
system has more electrical energy than a solvent-based
system. Therefore, only non-flammable fluids (as
defined above) can be sprayed with the system or used
to clean, flush, or purge the system.

Precautions must be taken when using electrostatic
waterborne equipment to avoid potential shock hazards.
When the electrostatic AA spray gun charges the iso-
lated fluid to high voltage, it is similar to charging a
capacitor or a battery. The system will store some of the
energy while spraying and retain some of that energy
after the spray gun is shut off. Do not touch the gun noz-
zle or come within 4 in. (102 mm) of the electrode until
the stored energy is discharged. The amount of time it
takes to discharge the energy depends on the system
design. Follow the Operating Checklist on page 22
before approaching the front of the gun.
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 spray gun is operated
above 60 kV.
