1.0 SAFETY INFORMATION
!
WARNING
(SEE WARNINGS IN REGARD TO DUCTWORK)
Do not install this unit in manufactured (mobile) homes. Improper installation
is more likely in manufactured housing due to ductwork material, size, loca-
tion, and arrangement. Installations in manufactured housing can cause a fire
resulting in property damage, personal injury or death.
EXCEPTION: Manufactured housing installations are approved only with docu-
mentation by a recognized inspection authority that the installation has been
made in compliance with the instructions and all warnings have been
observed.
!
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 installed 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 dam-
age, personal injury or death.
!
WARNING
(SEE SECTION 13.7: 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
disconnect switch may be required to de-energize the equipment.
Hazardous voltage can cause severe 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 stor-
age 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
monoxide from migrating into the living space.
• If air-moving equipment or ductwork is located in spaces containing fuel
burning appliances such as water heaters or boilers - all joints, seams, and
openings in the equipment and duct must also be sealed to prevent depres-
surization of the space and possible migration of combustion byproducts
including carbon monoxide into the living space.

WARNING
The first 36 inches of supply air plenum and ductwork must be constructed of
sheet metal as required by NFPA 90B. The supply air plenum or duct must
have a solid sheet metal bottom directly under the unit with no openings, reg-
isters or flexible air ducts located in it. If flexible supply air ducts are used they
may be located only in the vertical walls of a rectangular plenum, a minimum
of 6 inches from the solid bottom. Metal plenum or duct may be connected to
the combustible floor base, if not, it must be connected to the unit supply duct
flanges such that combustible floor or other combustible material is not
exposed to the supply air opening from the downflow unit. Exposing com-
bustible (non-metal) material to the supply opening of a downflow unit can
cause a fire resulting in property damage, personal injury or death.
Exceptions to downflow warnings:
• Installations on concrete floor slab with supply air plenum and ductwork
completely encased in not less than 2 inches of concrete (See NFPA 90B).
