Step 5 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 6 Install Supply Unit

to the factory lifting lugs (as shown in the
diagram) to lift and center the unit on the
curb/equipment support(s).
NOTE: THE USE OF ALL LIFTING LUGS
IS MANDATORY WHEN LIFTING UNIT.
Use self-tapping sheet metal screws to
fasten unit to the curb/equipment
support(s).
Use caution to avoid damaging exhaust
fan when installing supply unit.

The weatherhood can now be assembled and attached to
the installed unit. Assembly instructions are included with
