Warning Sign

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.

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.

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

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.

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.
