If installing under cabinets, keeping the fan
box flush to the underside will guarantee
correct spacing. Otherwise, center and
mark the installation area according to the
mounting bracket prior to hanging. Keep
4.5” below the underside of the cabinet to
allow the fan bracket to be installed later.
1. Insert/attach the top portion of the
MPK conduit through the fan box.
2. Attach the fan box to the mounting
bracket with included 8-32 nuts,
then complete the installation on
the MPK conduit and top/bottom
unions.
The fan box is 4.5” tall. If prepping a space
for install, 4.5” must be left between the
top of the mounting bracket and the
bottom of the cabinet.
The additional height of the unit should not
result in reduced range clearance.
Cabinets should be installed approximately
5” higher to accommodate the additional
size of the NFPA101 fan box assembly.

NOTE: The NFPA LSC (101) requires
500CFM of airflow in a 300A hood and
suppression system. This amount of
airflow, through a recirculating hood, will
create inefficiencies within the system
resulting in additional noise production.
