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.

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.

rotation is set in a clockwise rotation — when
looking down on the motor fan blade and agitator
blade. Counterclockwise rotation will potentially
damage the gear box and loosen the agitator
shaft. See the VFD manufacturer’s manual for
information on setting rotation direction, or for a
Graco supplied VFD, see manual 3A4793.
