electrical components. Only trained and qualified service
personnel should install, repair or service heating and air
conditioning equipment. Untrained personnel can perform
the basic maintenance functions of cleaning coils and

be performed by trained service personnel. When working
on heating and air conditioning equipment, observe
precautions in the literature, tags and labels attached to the
unit and other safety precautions that apply.

Agency recommendations.
