The air cleaner requires 24 VAC power and indoor fan
signal to operate. A transformer adequately sized to
power both the system and air cleaner is provided with
the air cleaner. Remove the transformer in the indoor unit
and replace with the transformer provided.
N
OTE: A 50 VA transformer is required for Trane/
American Standard Heating & Air Conditioning
furnace applications and 75 VA required for Trane/
American Standard Heating & Air Conditioning air
handler applications. If the indoor air handler
already has a properly sized transformer, no
replacement is required.
NOTE: When more than one whole house air cleaner
is used, 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.
NOTE: Trane/American Standard Heating & Air
Conditioning dual circuited air handlers matched
with heat pumps and Trane/American Standard
Heating & Air Conditioning oil furnaces will require
an accessory Transformer KIT# BAYTRANS12024

to
power the air cleaner. Do NOT replace air handler
transformer with the transformer supplied with the
air cleaner.
NOTE: Provide adequate strain relief for the low
voltage cable at the indoor unit.
CAUTION
!
DO NOT attach the power/control cable to a 120 Volt
EAC tap. The air cleaner uses 24 Volt power. Failure
to use 24 VAC results in permanent damage to the air
cleaner.
• Plug the air cleaner power/control cable into the air
cleaner door and route the cable into the indoor unit
low voltage wiring location.
• Connect the power/control wiring per Figures 22 &
22A.
NOTE: Wiring penetration must be sealed.
NOTE: For non-Trane/American Standard Heating & Air
Conditioning systems order a 120 VAC to 24 VAC
transformer, KIT# BAYTRANS12024

to provide 24 volt
power only to the air cleaner. Access to 120 VAC outlet
is required.
• Connect the power/control wiring per Figures 22 &
22A.
NOTE: Trane/American Standard Heating & Air
Conditioning Communicating Furnaces require KIT #
BAYACCECOMM101.
NOTE: Wiring diagrams for the Communicating Air
Handler, Communicating Furnaces and Oil Furnaces
are on pages 9-10, 11-13 and 14 respectively.

Transformer
• Transformer must have a grounded 120 VAC
power source. Do not defeat ground plug on the
transformer.
• Mount transformer to building structure with the
four provided wood screws.
Transformer not applicable to 50 Hz units.
NOTE: BAYTRANS12024C complies with the California
Code of Regulation,Title 20, Sections 1601 through
1608 dated December 2006. BAYTRANS12024A with
vendor’s manufacturing date codes after 0625 (YYWW)
cannot be installed in California because the transformer
does not satisfy the requirements set forth by California
Code of Regulations, Title 20, Sections 1601 through
1608 dated December 2006.
