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
RAV-180-01SI
. When you see this symbol on the
