Dual Whole House Air Cleaners
In some instances, two whole house air cleaners
can be utilized to manage the overall system
operational static pressure. The figure below
shows two whole house air cleaners installed on
an upflow furnace. The 24 volt transformer which
supplies power to the air cleaner will need to be
increased by 25 VA for each additional air cleaner
added.
See the wiring diagrams for information on how to
attach the wires in a two whole house air cleaner
system. The figure on the top of page 16 shows
the wiring hookup for two whole house air cleaners
attached to a furnace in conventional 24 V mode.
The figure on the bottom of page 16 shows the
wiring hookup for two whole house air cleaners
attached to a furnace in communicating mode.
Refer to the wiring diagrams on pages 8 through
14 for guidance on wiring the whole house air
cleaners to the system properly. All wires will be
run the same way for each of the two whole house
air cleaners.
