Preparing for installation
Venting air to the outside
When discharging the air into a ventilation
duct or directly through the ceiling into the
open, please take note of the following:
Exhaust air from the extractor hood
must not be directed into a flue or
chimney which is used for exhausting
the fumes or smoke from other
appliances burning gas or fuels.
Please ensure that regulations
concerning the discharge of exhaust
air have been fulfilled. (SABS IEC
60335-2-31).
For optimum extractor hood efficiency
use a short, smooth, round air exhaust
pipe with as few bends as possible. A 150
mm diameter exhaust pipe is
recommended. A long box section,
narrowed or bent pipes will hinder
performance and increase noise levels.
Connecting a 150 mm diameter pipe:
Mount the pipe directly onto the air
outlet on the extractor hood.
The extractor hood filters out solid
particles before the air is re-circulated,
via the vents on the side of the upper
chimney, back into the kitchen.
Re-circulating filtered air
The extractor hood has the ability to
either recirculate the filtered air back
into the kitchen, or the filtered air can
be circulated through a duct to the
outside of the building or into the
ceiling.
Decide on which option best suits you
before commencing with the installation.

An electric drill.
A saw for the chimney duct.
A star screw driver (Posi 2).

pencil.
