Preparing the location

It is recommended that the installation of the exhaust system is carried out before the hood.

Before making cut-outs, make sure the separation distances for fittings in the cavities of the ceiling or wall
are adequate.

Before mounting the cabinet to the wall, it may be easier to cut the first opening in the cabinet.

Disconnect the electrical power source.

Determine the evacuation method to use: discharge through the wall or roof.

Choose a flat surface for assembling the hood. Place the protective material on this surface.

Using two or more people, lift the hood and place it on the covered surface.

form a frame in the bottom of the cabinet. A support rod of ¾" (1.9 cm) thick (not supplied) may
be required for certain types of cabinets.
