Fig. 3, page 10, shows a typical Model PRO 3500wb waterborne system. The particular type and size sys- tem for your operation must be custom designed for your needs. For assistance in designing a system, contact your Graco representative.
Accessories are available from your Graco representa- tive. Refer to the Product Data Sheet for the gun, Form No. 305681.
Basic Guidelines
When spraying waterborne fluids electrostatically:
DThe gun must be connected to a voltage isolation system, which isolates the fluid supply from ground and allows voltage to be maintained at the tip of the gun.
DAll components of the isolation system that are charged to high voltage must be contained within a fence or enclosure that prohibits personnel from making contact with the high voltage components.
DThe 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.
Warning Signs
Mount the warning sign, part no. 186118, in the spray area where it can easily be seen and read by all opera- tors. Additional warning signs are available at no charge.
Ventilate the Spray Booth
WARNING
TOXIC FLUID HAZARD
Provide fresh air ventilation to avoid the buildup of toxic vapors. Do not operate the gun unless the ventilating fans are on.
Check and follow all local, state, and national codes regarding air exhaust velocity requirements. High velocity air exhaust will decrease the operating effi- ciency of the electrostatic system. The minimum allowable air exhaust velocity is 60 linear feet/minute (18.3 linear meters/minute).
