ELECTRICAL CONNECTIONS

The air cleaner requires 24 Volt AC power and indoor fan
signal for heating call to operate. A transformer adequately
sized to power both the system and air cleaner is provided
with the air cleaner.
NOTE: A 50 VA transformer is required for Furnace
applications and 75 VA required for Air Handler applica-
tions. If the indoor air handler already has a properly
sized transformer, no replacement is required.
Plug the air cleaner power/control cable into the air cleaner
door and route the cable into the indoor unit low voltage
wiring location.
