SAFETY CONSIDERATIONS

Improper
installation,
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
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.
ELECTRICAL SHOCK HAZARD
Failure to follow this warning will result in personal injury
or death.
Before performing service or maintenance operations on
unit, turn off main power switch to unit and install lock(s)
and lockout tag(s). Ensure electrical service to rooftop unit
agrees with voltage and amperage listed on the unit rating
plate. Unit may have more than one power switch.
WARNING
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal injury,
death and/or equipment damage.
R-410A refrigerant systems operate at higher pressures
than standard R-22 systems. Do not use R-22 service equip-
ment or components on R-410A refrigerant equipment.
