WARNING:
• 120 Volts may cause serious injury from electrical shock.
Disconnect power to the furnace/air handler before
starting installation. Leave power disconnected until
installation is completed.
• Arcing in electrical components may cause an explosion.
Do not install unit where explosive gasses will be present.
• Sharp edges may cause injury from cuts. Use care when
cutting and handling sheet metal.
• To reduce the risk of electrical shock, this equipment has a
grounding-type (three prong) plug. This plug will fit only
into a grounding-type power outlet. If the plug does not fit
into the outlet, contact qualified personnel to install the
proper outlet. Do not alter this plug in any way.
• To reduce the risk of electrical shock, locate product so
that the power cord can be plugged into an electrical outlet
without the use of an extension cord.
CAUTION:
• To prevent component failure, do not install the air cleaner
on the warm air supply or in an area where the temperature
may exceed 125° F. This may include areas above heat
exchangers in downflow furnaces or above exhaust flues in
lowboy furnace cold air returns.
• The air cleaner must be installed where the ambient air
temperature remains between 40° F and 125° F [4° C
and 52° C].
• Installation must conform to all applicable codes.
• Do not install an atomizing humidifier upstream of the air
cleaner. Water or mist will cause power supply to shut down.
