Using waterborne coating with electrostatic equipment
requires that the fluid source be isolated from ground.
Precautions should be taken to ensure operation safety
and system efficiency. The following guidelines should
be followed:
• The fluid lines and source MUST be isolated from
ground. An isolating Paint Stand or similar isolating
(non-porous) material MUST be used.
• Isolation stands MUST be at least 18-inches from
grounded booth walls, chain link fences, or other
grounded objects.
• Air hoses to the pressure pot or pump on the insulating
stand should be non-conductive plastic. Many rubber
hoses will have static grounding circuits or carbon
content and are NOT suitable for this application.
• All charged (isolated) systems MUST be inside a fence
or cage to prevent contact by personnel. An interlock
system MUST be provided that interrupts high voltage
flow to the applicator if the gate is opened.
2. All objects inside spray area must be grounded -
reference EN 50 176 and/or NFPA-33. Resistance
to earth ground must be less than 1 meg Ohm.
Interlocks Required
Interlock the solvent supply with the main supply air
to the applicator. When solvent is On, main supply air
to the applicator is Off. Interlocks are user supplied.
WATERBORNE ISOLATION
SYSTEM INSTALLATION
GUIDELINES
• Air regulations for pots or pumps should be mounted
remotely outside the fence or cage area to facilitate
changes in pressure without shutting the system
down.
• Grounding hooks at the cage MUST be used to ground
the system when personnel are working close by.
• Fluid lines to the applicator MUST be protected from
scraping and abrasion on the floor or sharp metal
edges that could lead to voltage pin holing and loss
of kV on the charged system.
• Cleanliness and maintenance are extremely critical.
APPLICATOR INSTALLATION
1. Ensure there is a true earth ground connection available.
Connect the air hose ground to this connection.
2. Turn off power.

The air hose ground must be connected
to true earth ground.
Typical installation to spray non-flammable
conductive materials (waterborne materials)
must not be used to handle flammable
materials (solvent based materials).
The solvent supply must be interlocked
with applicator supply air.
