N N o o t t e e : : The manufacturer recommends installing only approved matched indoor and outdoor systems. All of the manufacture's split
systems are AHRI rated only with TXV/EEV indoor systems. Some of the benefits of installing approved matched indoor and
outdoor split systems are maximum efficiency, optimum performance and the best overall system reliability.
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.
