smash into it or where stand mountings seriously
interrupt building traffic patterns. The number of
units required by air volume and air changes per
hour might need to be increased when the shape
of a structure is such that effective capturing and
air distribution is not possible according to the
sizing calculations.

–
F72 ELECTRONIC AIR CLEANER CAPACITY AND EFFICIENCY.
AIR CONDITIONING
Make certain the cooling coil is installed
downstream from the air cleaner cabinet to
prevent condensation and chilled air (cooler than
50°F [10°C]) from entering the cell.
HUMIDIFIERS
Location of the system humidifier is important to
the operation of the air cleaner. An evaporative-
type humidifier may be installed between the
furnace warm air duct and the return air duct
without affecting the electronic air cleaner. An
atomizing-type humidifier should be installed
downstream from the air cleaner. If the atomizing-
type humidifier is installed upstream, mist, salts
and minerals may decrease the efficiency of the
electronic cell and create a need for equipment
service.
When the atomizing-type unit
must
be used
upstream from the F72, the following precautions
should be taken:
1. It must be installed as far from the air cleaner
as possible.
2. A standard, disposable-type furnace filter
should be installed between the humidifier and
the air cleaner to trap water droplets and
mineral salts.
3. The electronic cell must be washed frequently
to prevent a mineral deposit buildup.
