The 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 and/
or service air conditioning
equipment.
Untrained personnel can perform
basic maintenance functions
such as cleaning coils and
cleaning or 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
equipment and all other safety
precautions that may apply.
Improper installation,
adjustment, alteration, service,
maintenance, or use can cause
explosion, fire, electrical shock
or other hazardous conditions
which may cause serious
personal injury and/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 kits
or accessories when installing.
Follow all safety codes. Wear
safety glasses and work
gloves. Use quenching cloth for
brazing operations. Have fire
extinguisher available. Read
these instructions thoroughly and
follow all warnings or cautions
attached to the equipment.
Consult local building codes
and the National Electrical Code
(NEC) for special installation
requirements.
Understand the signal words -
danger, warning and caution.
Danger identifies the most
serious hazards which will result
in severe personal injury or
death. Warning signifies hazards
that could result in personal
injury or death. Caution is used
to identify unsafe practices,
which would result in minor
personal injury or product and
