SAFETY CONSIDERATIONS

Installation of this unit can be hazardous due to electrical com-

ponents and equipment location (such as a ceiling or elevated

structure). Only trained, qualified installers and service

mechanics should install and service this equipment.
When installing this unit, observe precautions in the literature,

labels attached to the equipment, and any other safety precau-

tions that apply.
