Some local codes limit the maximum amount of CFM a range hood can move. ACT™ allows you
to control the maximum blower CFM of select Zephyr Ventilation range hoods without the need for
expensive make up air kits. ACT™ enables the installer to easily set the maximum blower speed to one
of two most commonly specified CFM levels; AK9228BS & AK9234BS - 290 or 390 CFM, AK9240BS &
AK9446BS - 590 or 390 CFM. The usage of ACT™ may not be necessary for your installation. Please
check your local codes for CFM restrictions.
By default, the maximum blower CFM is set to 600 for AK9228BS & AK9234BS and 1200 for AK9240BS
& AK9246BS.
Hood must be disconnected from the main power prior to
performing the conversion instructions listed below. Failure to do
so could result in personal injury or damage to the product.
CAUTION
After re-positioning the jumper and powering on the hood, the
CFM cannot be changed again.
