step 4 (continued)
The use of a duct adapter with the supply duct
is strongly recommended to properly align the
ductwork with the supply fan discharge. The
duct adapter is only a guide and is not intended
to be used as support for the ductwork.
step 5 apply sealant
Before installing fans, apply a sealant around
the perimeter of the exhaust and supply
duct adapter to isolate the fan and minimize
vibration.
step 6 install exhaust Fan
Install CUBE exhaust fan on curb extension.
Fasten with self-tapping sheet metal screws
through existing holes in curb cap. NFPA
96 requires the exhaust fan be hinged.
Greenheck offers an optional hinge kit with
restraining cables and a grease trap with
drain connection. Install these options at
this time.
nOte: Installing the exhaust fan prior to the
supply unit will allow for easier installation of
options.
step 7 install supply Unit
Use a crane and a spreader bar hooked
to the factory lifting lugs (as shown in the
diagram) to lift and center the unit on the
curb and equipment support. Use self-
tapping sheet metal screws to fasten unit
to the curb and equipment support through
holes provided.
Electrical connections can be made at this
time.
Use caution to avoid damaging exhaust fan
when installing supply unit.
