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.
