Rotating Parts & Electrical Shock Hazard:
Disconnect electric power before working on unit.
Follow proper lockout / tagout procedures to ensure
the unit cannot be energized while being installed or
serviced.
A disconnect switch should be placed near the fan
in order that the power can be swiftly cut off, in case
of an emergency and in order that maintenance
personnel are provided complete control of the
power source.
Grounding is required. All field-installed wiring
must be completed by qualified personnel. All field
installed wiring must comply with National Electric
Code (NFPA 70) and all applicable local codes.
Failure to follow these instructions could result in
death or serious injury.
