SAFETY CONSIDERATIONS
1
Installation and servicing of air-conditioning equipment
can be hazardous due to system pressure and electrical
3
components. Only trained and qualified service personnel
3
should
install,
4
equipment. Untrained personnel can perform only the
basic maintenance functions such as replacing filters.
9
Trained service personnel should perform all other service
12
and maintenance operations.
13
When working on air-conditioning equipment, observe
16
precautions in the literature, tags and labels attached to
22
the unit, and other safety precautions that can apply.
Follow all safety codes. Wear approved safety glasses and
23
leather work gloves. Use quenching cloth for unbrazing
23
operations. Have fire extinguishers available for all
24
brazing operations.
27
Read these instructions thoroughly and follow all
30
warnings or cautions attached to the unit. Consult local
building codes and National Electrical Code (NEC) for
37
special requirements.
38
Recognize safety information. This is the safety ALERT
38
symbol
. When you see this symbol on the unit and in
instructions or manuals, be aware of the potential for
38
physical injury hazards.
40
Understand the signal words DANGER, WARNING, and
40
CAUTION. These words are used with the safety- - ALERT
42
symbol. DANGER indicates a hazardous situation which,
if not avoided, will result in death or severe personal
42
injury. WARNING indicates a hazardous situation which,
43
if not avoided, could result in death or personal injury.
44
CAUTION indicates a hazardous situation which, if not
avoided, could result in minor to moderate injury or
46
product and property damage. NOTICE is used to address
52
practices not related to physical injury. NOTE is used to
62
highlight suggestions which will result in enhanced
installation, reliability, or operation.
