Installation, Operation, and Maintenance

SAFETY WARNING

Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-
conditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment 
by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in the literature and 
on the tags, stickers, and labels that are attached to the equipment.
