Installation
Typical Roof Mounting Installation
1. On the roof surface, cut an appropriate sized hole
and follow manufacturer’s instructions on curb
installation. Caulk and
flash the curb to
ensure a water
tight seal.
2. If unit is equipped with a backdraft damper, it
should be installed now.
3. Remove motor cover. Access to the motor
compartment is accomplished by removing the
screws as shown in figure 3.
4. For CUBE Belt Drive fans only. On the drive frame
use the lifting lugs to lift and place the unit on top of
roof curb. (Refer to figure 2 on page 2).
5. Secure fan to curb using a minimum of eight lag
screws, metal screws or other suitable fasteners.
Shims may be required depending upon curb
installation and roofing material.
6. Verify power line wiring is de-energized before
connecting fan motor to power source.
7. Connect power supply wiring to the motor as
indicated on the motor nameplate or terminal box
cover. Check the power source for compatibility
with the requirements of your equipment.
8. Check fan wheel for free rotation, re-center if
necessary.
9. Check all fasteners for tightness.
10. Mount and wire safety disconnect switch under
motor cover. Wire control switches at ground level,
refer to figure 4.

ELECTRICAL - If fan motor is NOT thermally protected,
remote overload protection must be installed having
adequate rating as to voltage, frequency, horsepower, and
full load current per phase. Where connected to a circuit
protected by fuses, use time delay fuses. For supply
connection use wires rated for at least 194˚F (90˚C).
INSTALLATION - When connecting electrical power to this
fan, do not restrict motor movement for possible future belt
or wheel adjustment.
CAUTION - Mount with the lowest moving part at least
8 ft (2.5m) above floor or grade level. Not required on roof
mounted ventilators or duct mounted ventilators provided
with belt guards.
11. Replace motor cover.
12. For restaurant and UL Listed for smoke evacuation
applications, the electrical supply must enter the
motor compartment through the breather tube.
For other non-flammable applications the electrical
supply can be routed through the conduit chase
between the curb cap and the bottom of the motor
compartment.
