ELECTRICAL CONNECTIONS FOR DUAL WHOLE HOUSE AIR CLEANER
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 10 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 10 shows the
wiring hookup for two whole house air cleaners
attached to a furnace in communicating mode.
Refer to the wiring diagrams on pages 3 through 8
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.
