Preparing for installation.

The extractor hood has the ability to ei-
ther recirculate the filtered air back into
the kitchen, or to vent the filtered air
through an outside wall.
Decide on which option best suits you be-
fore commencing with the installation.

The extractor hood is intended to be
mounted onto a flat perpendicular kitchen
wall capable of supporting the weight of
the hood. (approximately 26 kg.)


Tools required for installation:

An electric drill.

A 3.5 mm dia. steel drill bit.

8mm and 5mm dia. masonry drill bits

A star screw driver (Posi bit 2).

A ratchet with a 10mm socket and a
100mm extension.

A tape measure, masking tape and a
pencil.

Venting air to the outside.

When discharging the air into a ventila-
tion shaft or directly through the wall
into the open , please take note of the fol-
lowing:

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 appliances
burning gas or fuels.

Please ensure that regulations concern-

ing 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 150mm diame-
ter exhaust pipe is recommended. 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.

Connecting a 125 mm or 100mm di-

ameter pipe: Attach a reducing connec-
tor (available from a specialist retailer)
to the air pipe and then attach to the ex-
haust-air duct.

Care must be taken during installation not
to obstruct these vents.
No ducting is required for this type of in-
stallation.

The extractor hood filters out solid particles
before the air is re-circulated, via the vents
on the side of the upper chimney, into the
kitchen.
