SAFETY CONSIDERATIONS

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, or
service air-conditioning equipment.
Untrained personnel can perform basic maintenance functions of
cleaning coils and filters and 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 unit, and other safety
precautions that may apply.
Follow all safety codes. Wear safety glasses and work gloves. Use
quenching cloth for unbrazing operations. Have fire extinguisher
available for all brazing operations.
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.
IMPORTANT: The use of this manual is specifically intended
for a qualified installation and service agency. A qualified instal-
lation and service agency must perform all installation and ser-
vice of these appliances.
Units with DX evaporator coils contain the refrigerant R-410A.
Review the R-410A Material Safety Data Sheet (MSDS) for
hazards and first aid measures.
Refrigerant charging should only be carried out by an
EPA-certified air conditioning contractor.
WARNING
Before performing service or maintenance operations, turn off
main power switch to the unit. Electrical shock could cause
personal injury.
