WATERBORNE
ISOLATION SYSTEM
INSTALLATION
GUIDELINES
Using waterborne coating with electrostatic equip-
ment 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 wood products, wooden box-
es, pallets, or boards as an isolator. Wood
contains moisture and is a poor insulator.
Electrical current passing through these ma-
terials can ignite them, causing a hazardous
condition.
C A U T I O N !
• 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.
WATERBORNE HOSE
FITTING INSTALLATION
For 79523 R90 Cascade - Waterborne: Rans-
burg supplies the waterborne fluid hose factory
pre-assembled to the applicator unit. Standard
hose lengths are 10m, 15m, and 25m. To modify
the hose length, use the following procedures. All
adjustments must be made at the supply end of
the system.
1. Remove the male connector and swivel fitting
from the end of the fluid hose by turning the nut
of the male connector counter-clockwise while
holding its main body.
2. Remove the male connector nut from the fluid
hose.
3. Determine the hose length that is needed and
cut the hose off squarely.
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.
Refer to "Installation - 79500 R90 Solventborne,
79501 R70 Solventborne Installation" in the
"Installation" section of this manual.
† Typical installations to spray non-flam-
mable conductive materials (waterborne ma-
terials) must not be used to handle flamma-
ble materials (solvent based materials).
