1.0 SAFETY INFORMATION
!
WARNING
(SEE SECTION 3.2: VERTICAL UPFLOW & HORIZONTAL LEFT)
If unit is to be installed without an indoor coil, return air duct, or plenum, it must
not be in stalled directly over combustible material. If installed without an indoor
coil with a return duct or plenum, the air plenum or duct must have a solid sheet
metal bottom with no return air openings, registers or flexible air ducts located
directly under the unit. Exposing combustible material to the return opening of an
upflow unit without an indoor coil can cause a fire resulting in property damage,
personal injury or death.

WARNING
Duct leaks can create an unbalanced system and draw pollutants such as dirt,
dust, fumes and odors into the home causing property damage. Fumes and odors
from toxic, volatile or flammable chemicals, as well as automobile exhaust and
carbon monoxide (CO), can be drawn into the living space through leaking ducts
and unbalanced duct systems causing personal injury or death (see Figure 1).
• If air-moving equipment or ductwork is located in garages or off-garage storage
areas - all joints, seams, and openings in the equipment and duct must be
sealed to limit the migration of toxic fumes and odors including carbon monox-
ide from migrating into the living space.
• If air-moving equipment or ductwork is located in spaces containing fuel burn-
ing appliances such as water heaters or boilers - all joints, seams, and openings
in the equipment and duct must also be sealed to prevent depressurization of
the space and possible migration of combustion byproducts including carbon
monoxide into the living space.

WARNING
(SEE SECTION 14.7: ECM CONTROL MODULE REPLACEMENT)
Always have 240 volt power turned off to the furnace before attempting any
replacement of the motor or control module. Failure to do so may result in seri-
ous equipment damage, personal injury or death.
!
WARNING
(SEE SECTION 4.0: ELECTRICAL WIRING)
Disconnect all power to unit before installing or servicing. More than one dis-
connect switch may be required to de-energize the equipment. Hazardous volt-
age can cause severe personal injury or death.
!
WARNING
(SEE SECTION 4.3: GROUNDING)
The unit must be permanently grounded. Failure to do so can result in electrical
shock causing personal injury or death.
!
WARNING
(SEE SECTION 14.0: MAINTENANCE)
Units with circuit breaker(s) meet requirements as a service disconnect switch,
however, if access is required to the line side (covered) of the circuit breaker,
this side of the breaker(s) will be energized with the breaker(s) de-energized.
Contact with the line side can cause electrical shock resulting in personal
injury or death.

WARNING
(SEE SECTION 14.5: BLOWER ASSEMBLY REMOVAL & REPLACEMENT)
If removal of the blower assembly is required, all disconnect switches supplying
power to the airhandler must be de-energized and locked (if not in sight of unit)
so the field power wires can be safely removed from the blower assembly. Failure
to do so can cause electrical shock resulting in personal injury or death.
