Caveat
The product that is described in this manual is designed to ensure the safety of the
customer. Nevertheless, the manufacturer declares that the product is not ready for
use, installation, or operation without electrical certification or field inspection. The
manufacturer explicitly emphasizes that the product is sold “as is” and is not fit for use
in its present state without compliance with applicable regulations and codes. By
purchasing the product, the customer fully and willingly accepts to bear the
responsibility to certify the product, if necessary, before it can be installed or operated
in their jurisdiction. Consequently, the manufacturer is not liable to all forms of
contract or tort, whether direct or indirect without any limitation, if compliance or
enforcement of a lack of compliance is required by the Authority Having Jurisdiction
where the product is purchased and/or installed.
NOTE 
Excessive force shall not
be applied when
replacing the filter in the
supply vent (A).
NOTE 
The length of a newly
installed duct shall be
5 in (~12.7 cm).
