Only trained, qualified installers and service mechanics should install, start−up, and service
this equipment. Untrained personnel can perform basic maintenance functions such as
cleaning coils.
When working on the equipment, observe precautions in the literature and on tags, stickers,
and labels attached to the equipment.
Follow all safety codes. Wear safety glasses and work gloves. Keep a quenching cloth and
fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky
equipment.
