Preparing for installation

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.

The extractor hood is intended to be mounted onto a flat perpendicular kitchen wall capable of supporting the weight of the hood. (approx. 16 to 26 kg depending on the model).

Tools required for installation:

An electric drill.

A 3.5 mm diam. steel drill bit.

8 mm & 5 mm diam. masonry drill bits

A star screw driver (Posi 2).

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

A tape measure, masking tape and a pencil.

Recirculating filtered air

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

Care must be taken during installation not to obstruct these vents.

No ducting is required for this type of installation.

Venting air to the outside

When discharging the air into a ventilation duct or directly through the wall 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

mmdiameter 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 100 mm diameter pipe: Attach a reducing connector (available from a specialist retailer) to the air pipe and then attach to the exhaust-air duct.
