ACT™ Conversion
‹”ů‘™‘–”‘Ž‡ Š‘Ž‘‰›ĬĻĭ
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, 390 or 290 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 650.
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.
