sessing adequate backgrounds of electrical and mechani-
cal experience. Any attempt to repair a central air condi-
tioning product may result in personal injury and/or prop-
erty damage. American Standard Inc. or seller cannot be

Safety signal words are used to designate a degree or
level of seriousness associated with a particular hazard.
The signal words for safety markings are DANGER,
WARNING, and CAUTION.
a. DANGER indicates an imminently hazardous
situation which, if not avoided, will result in death
or serious injury. This signal word is limited to the
most extreme situations.
b. WARNING indicates a potentially hazardous situa-
tion which, if not avoided, could result in death or
serious injury.
c. CAUTION indicates a potentially hazardous situa-
tion which, if not avoided, may result in minor or
moderate injury. It is also used to alert against
unsafe practices and hazards involving only prop-
erty damage.
There must be a free flow of fresh air sufficient for efficient
combustion and safe ventilation of your furnace. Do not
allow the louvers on the front panels of your furnace to
become blocked as this will restrict the flow of fresh air.
The combustion air for your furnace must be fresh uncon-
taminated air. Paints, varnishes, laundry bleaches, deter-
gents, many household cleaners, water softening salts,
adhesives, and all such products release fumes containing
compounds which could lead to early heat exchanger and
vent system deterioration. Do not store these type of
products near your furnace and consider fresh air for your
furnace during construction or remodeling.
