For optimum
hood efficiency:
Short, smooth duct pipe.
As few bends in the ducting as possible.
Diameter of ducting to be as large as
possible and no tight bends in ducting.
If long, rough exhaust-air
ducting,
many ducting bends or smaller pipe
diameters
are used, the air extraction
rate will no longer be at an optimum
level and there will be an increase in
noise.
IMPORTANT: The manufacturer
of the
hood accepts
no liability for
complaints
which can be attributed
to
the design and layout of the duct-
work.
Round pipes:
We recommend
Internal diameter: 6".
Flat ducts must have an internal cross-
section that equates to that of round
pipes.
There should be no sharp bends.
¢ 6" approx. 50.3 inches 2
If pipes have different diameters:
Insert sealing strip.
For exhaust-air
mode, ensure that
there is an adequate supply of fresh air.
CONNECTING A ¢ 6" EXHAUST-AIR
DUCT:
Mount the duct directlyonto the air out-
let on the hood.
Step
2: PREPARING
THE CEILING
The ceiling must be flat and horizontal.
Make sure that the ceiling can bear the
applied loads.
The provided screws and wall plugs are
suitable for solid masonry. On all other
wall types (e. g. plasterboard, porous
concrete, Poroton bricks) use the appro-
priate fasteners.
Ensure that the ceiling is capable of pro-
viding a firm hold for mounting screws
and plugs.
