Ground Connections

NOTE: Use UL listed conduit and conduit connectors for connecting
supply wire(s) to unit to obtain proper grounding. Grounding may also
be accomplished by using grounding lugs provided in control box.
ELECTRICAL SHOCK HAZARD
Failure to establish uninterrupted or unbroken ground could result in
personal injury and/or death.
According to NEC, NFPA 70, and local codes, the cabinet must have an
uninterrupted or unbroken ground to minimize personal injury if an
electrical fault should occur. The ground may consist of electrical wire
or metal conduit when installed in accordance with existing electrical
codes. If conduit connection uses reducing washers, a separate ground
wire must be used.

Minimum CFM and Motor Speed Selection

The fan speed selection is done at the motor connector. Units require a
minimum CFM. Refer to the unit wiring label to ensure that the fan
A94060A
speed selected is not lower than the minimum fan speed indicated.
