WARNING
SAFETY CONSIDERATIONS
Improper installation, adjustment, alteration, service, maintenance,
or use can cause explosion, fire, electrical shock, or other
conditions which may cause death, 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, protective clothing,
and work gloves. Use quenching cloth for brazing operations.
Have
fire
extinguisher
available.
Read
these
instructions
thoroughly and follow all warnings or cautions included in
literature and attached to the unit. Consult local building codes and
National Electrical Code (NEC) for special requirements.
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 these signal words: DANGER, WARNING, and
CAUTION. 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.
!
WARNING
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury
or death.
Before installing, modifying, or servicing system, main
electrical disconnect switch must be in the OFF position.
There may be more than one disconnect switch. Lock out
and tag switch with a suitable warning label.
CAUTION
!
EQUIPMENT DAMAGE HAZARD
Failure to follow
this caution may result in equipment
damage or improper operation.
Do not bury more than 36 in. (914 mm) of refrigerant pipe
in the ground. If any section of pipe is buried, there must be
a 6 in. (152 mm) vertical rise to the valve connections on
the outdoor units. If more than the recommended length is
buried, refrigerant may migrate to the cooler buried section
during extended periods of system shutdown. This causes
refrigerant slugging and could possibly damage the
compressor at start--up.
