Agitator Kit Accessory
To add an agitator to the Graco isolation system, order
Part No. 245895. See
Agitator Kit 245895 , page 56, for
the kit parts list.
1. Discharge the system voltage (see Fluid Voltage
Discharge and Grounding Procedure , page 22).
2. Relieve the pressure (see Pressure Relief Proce-
dure , page 22).
3. Open the isolated enclosure door.
4. Remove the back of the control box (258).
5. Remove tube (A2) from elbow (282) at the air mani-
fold; see
Tubing and Wiring , page 54. Install the Y
fitting (402) into the elbow. Install tubes (A2) and
(407) into the Y fitting. Route the agitator tube (407)
into the cabinet.
6. Replace the back of the control box (258).
7. Assemble the other parts of the kit as shown.
Secure the agitator with the setscrew (408).
8. Return the system to service.
Grounding
The following are minimum grounding requirements for
a basic electrostatic waterborne system. Your system
may include other equipment or objects which must be
grounded. Check your local electrical code for detailed
grounding instructions. Your system must be connected
to a true earth ground.
•
Electrostatic Air Spray Gun:
ground the gun by con-
necting the red-colored Graco Grounded Air Hose
to the turbine air inlet and connecting the air hose
ground wire to a true earth ground. See
Check
Electrical Grounding, page 19
•
Voltage Isolation System:
electrically connect the
voltage isolation system to a true earth ground.
•
Air compressors and hydraulic power supplies:
ground the equipment according to the manufac-
turer's recommendations.
•
All persons entering the spray area:
shoes must
have conductive soles, such as leather, or personal
grounding straps must be worn. Do not wear shoes
with non-conductive soles such as rubber or plastic.
•
Object being sprayed:
keep the workpiece hangers
clean and grounded at all times. Resistance must
not exceed 1 megohm.
•
The floor of the spray area:
must be electrically con-
ductive and grounded. Do not cover the floor with
cardboard or any non-conductive material which
would interrupt grounding continuity.
•
Flammable liquids in the spray area:
must be kept in
approved, grounded containers. Do not use plastic
containers. Do not store more than the quantity
needed for one shift.

When operating the electrostatic gun, any
ungrounded objects in the spray area (people,
containers, tools, etc.) can become electrically
charged. Improper grounding can result in static
sparking, which can cause a fire, explosion, or
electric shock. Ground all equipment, personnel,
object being sprayed, and conductive objects in or
close to the spray area. Resistance must not exceed
1 megohm. Follow the grounding instructions below.
