For a Graco supplied VFD, see manual 3A4793 for
information on VFD installation and operation.
Connect VFD to Motor
NOTICE
To avoid equipment damage, do not plug the
motor directly into a wall socket. The motor must
be wired to a VFD.
The equipment must be grounded to reduce the
risk of static sparking and electric shock. Electric
or static sparking can cause fumes to ignite or
explode. Improper grounding can cause electric
shock. Grounding provides an escape wire for the
electric current.
The drum cover and all electrically conductive
objects or devices in the dispensing area must be
properly grounded. Check your local electrical code
for detailed grounding instructions for your area and
type of equipment.
To ground the agitator, connect one end of the
ground wire (G) to the ground connector on the
agitator (33). Connect the other end of the ground
wire to a true earth ground.
NOTE: Ground wire is not supplied. To order
separately, use part number 237569, Wire Assembly,
25 FT.
Follow the instructions in the motor manufacturer’s
manual provided with this agitator to connect the
VFD to the motor. Wire size, fuse size, and other
electrical devices must comply with all local codes
and regulations.
Motors are equipped with an automatic thermal
protective device. Review the warning label on the
motor stating the requirement for connecting to the
control circuit terminals of the VFD. UL and NEC
require connection of motor thermostat leads P1 and
P2 into the control portion of a manual reset start
circuit.
For Graco supplied VFDs, motor thermostat leads P1
and P2 connect to terminals 4 and 13B on the VFD,
as shown below.

Operation
Finding the Proper Agitator Speed
Operation
1. Fill the fluid supply container to about 3 or 4
inches (75 to 100 mm) above the agitator blade.
2. Start the agitator and gradually increase the
speed until a vortex begins to form in the fluid.
3. Reduce the speed slightly, then fill the fluid
container.
To reduce the risk of serious injury, including cuts,
amputation of fingers by the agitator blades, and
splashing in the eyes or on the skin, always power
off and disconnect power to the VFD before raising,
checking, or repairing the agitator.
NOTE: Speed is limited to approximately 300 rpm for
the 12” (30 cm) impeller.
If using a Graco supplied VFD, the agitator speed
can be calculated by using the formula below, or
determined by the graph below using the VFD
frequency.
Equipment surfaces and fluid that is heated can
become very hot during operation, resulting in
severe burns. To avoid severe burns do not touch
hot fluid or equipment.
Example 1: (AIB) x C = D
Example 2: (10 hz I60 hz) x 1725 rpm = 292 rpm
General Operation
Use the VFD to start, stop, and adjust the agitator
speed. See the VFD manufacturer’s manual for
operating information. For a Graco supplied VFD,
see manual 3A4793 for operating information.
Agitators are used to maintain solids in suspension.
If solids have settled in the container, use a shaker
or some other device to bring product back in
suspension before installing and operating the
agitator.
