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.
