Depending on the product, the lighting is pre-wired by
hood section to a junction box. Certain model
requires that each fixture to be connected. Refer to
the schematic of this control provided on the
manufacturing plans to ensure that the wiring is done
properly.
Access on top of exhaust hoods

maintenance, electrical wiring and access control
components, plumbing fittings, and fire suppression
system components even after the installation and
construction is completed.
Exhaust hood skirting
It is possible to install a hood skirting provided by
Cadexair or not above the hood. The installation
method may vary according to the exhaust hood
model. The hood skirting can be installed with a “Z”
component installed on the back panel of the hood
skirting. Depending on the height of the hood skirting,
tracks or any other methods might be necessary to
support the hood skirting. An assembly with screws
allow keeping corners together.

hood skirting, suspended ceilings or
other. This will void the exhaust hood
homologation

installation according to plans provided by a seismic
specialized engineer.
Fire suppression system

mandatory with this type of hood above cooking
equipment for the exhaust ducts and cooking
equipment. This system is activated by fusible links or
thermal detectors integrated to the exhaust hood. In
case of fire, the air exhaust is maintained and the air
supply is stopped. Filters housing, exhaust collar and
cooking surface are sprayed with a chemical product.
Energy sources like gas and electricity are interrupted
for the cooking equipment and hood lightings and an
alarm system sounds.
