SAFETY CONSIDERATIONS
Installation and servicing of air-conditioning equipment can be
hazardous due to system pressure and electrical components. Only
trained and qualified service personnel should install, repair, or
service air-conditioning equipment. Untrained personnel can per-
form the basic maintenance functions of replacing filters. Trained
service personnel should perform all other operations.
When working on air-conditioning equipment, observe precau-
tions in the literature, tags and labels attached to the unit, and
other safety precautions that may apply. Follow all safety codes.
Wear safety glasses and work gloves. Use quenching cloth for
unbrazing operations. Have fire extinguishers available for all
brazing operations.
Follow all safety codes. Wear safety glasses and work gloves. Use
