SAFETY CONSIDERATIONS

Improper installation, adjustment, alteration, service,

maintenance, or use can cause explosion, fire, electrical

shock or other conditions which may cause personal

injury or property damage. Consult a qualified installer,

service agency, or your distributor or branch for

information or assistance. The qualified installer or

agency must use factory--authorized kits or accessories

when modifying this product. Refer to the individual

instructions packaged with the kits or accessories when

installing.

Follow all safety codes. Wear safety glasses and work

gloves. Use quenching cloths for brazing operations and

have a fire extinguisher available. Read these instructions

thoroughly and follow all warnings or cautions attached to

the unit. Consult local building codes and appropriate

national electrical codes (in USA, ANSI/NFPA70,

National Electrical Code (NEC); in Canada, CSA C22.1)

for special requirements.

It is important to recognize safety information. This is the
safety--alert symbol

. When you see this symbol on the

unit and in instructions or manuals, be alert to the

potential for personal injury.

Understand the signal words DANGER, WARNING,

CAUTION, and NOTE. These words are used with the

safety--alert symbol. DANGER identifies the most serious

hazards which

will

result in severe personal injury or

death. WARNING signifies hazards which

could

result in

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.
