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 perform basic maintenance functions
of cleaning coils and filters and replacing filters. All other
operations should be performed by trained service personnel.
When working on air-conditioning equipment, observe
precautions 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
extinguisher available for all brazing operations.
It is important to recognize safety information. This is the
safety-alert symbol
and in instructions or manuals, be alert to the potential for
personal injury.
