SAFETY CONSIDERATIONS

1
Installation and servicing of air-conditioning equipment
can be hazardous due to system pressure and electrical
2
components. Only trained and qualified service personnel
3
should
install,
5
equipment. Untrained personnel can perform the basic
maintenance functions of replacing filters. Trained service
7
personnel should perform all other operations.
9
When working on air-conditioning equipment, observe
13
precautions in the literature, tags and labels attached to
13
the unit, and other safety precautions that may apply.
18
Follow all safety codes. Wear safety glasses and work
gloves. Use quenching cloth for unbrazing operations.
19
Have fire extinguishers available for all brazing
20
operations.
20
Follow all safety codes. Wear safety glasses and work
21
gloves. Use quenching cloth for brazing operations. Have
23
fire extinguisher available. Read these instructions
thoroughly and follow all warnings or cautions attached to
32
the unit. Consult local building codes and National
50
Electrical Code (NEC) for special requirements.
50
Recognize safety information. This is the safety- - alert
.
52
symbol
. When you see this symbol on the unit and in
53
instructions or manuals, be alert to the potential for
personal injury.

63
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety- - alert
69
symbol. DANGER identifies the most serious hazards
which will result in severe personal injury or death.
70
WARNING signifies a hazard which could result in
73
personal injury or death. CAUTION is used to identify
unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced
installation, reliability, or operation.
