GUIDELINES GUIDELINES
Using waterborne coating with electrostatic
equipment requires that the fluid source be isolated
from ground. Precautions should be taken to
ensure operator 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.
Never use wooden boxes, pallets, or boards
for isolators as wood will absorb moisture and
poor poor
is a poor poor poor insulator.

boxes, pallets, or boards as an isolator.
Wood contains moisture and is a poor
insulator. Electrical current passing
through these materials can ignite them,
causing a hazardous condition.
• Isolation stand MUST be at least 18-inches
from the grounded booth wall, chain link fence,
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.
• Air regulators 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.

Starting at the applicator, route the air hose along
the same path as the low voltage cable to the low
voltage control unit. The fluid hose can be run with
the low voltage cable and air hose or it can be
separate and run to the fluid source. Do not
expose the hoses to high temperatures (over
120 o F) and/or conditions such as moving parts,
foot traffic, vehicle traffic, etc.
Prior to connecting the air hose to the low voltage
unit and the fluid hose to the fluid supply, adjust the
hose and low voltage cable position at the applicator
to relieve some strain on the low voltage cable. To
do this follow the following procedure.
1. Disconnect the air hose from the applicator.
2. Position the air hose 1-inch (2.5 cm) away from
the bottom of the handle.
3. Secure the air hose to the low voltage cable.
Secure the two together at one additional location,
about 12-16 inches (30-41 cm) back.
4. With a wrench, reconnect and secure the air
hose to the applicator. (This should form a small
loop in the low voltage cable.)
5. Secure the fluid hose to the air hose and low
voltage cable as needed.
