Model 5000 Electronic Air Cleaner
Installation Instructions
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 140°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 32°F and 140°F
[0°C and 60°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.
Do not plug the air cleaner into an outlet that is always
live. The outlet must only be live when the furnace/air
handler blower is operating. Failure to properly wire
the outlet can result in excessive ozone production.
