performance when ducting it is important the ducting that carries the fumes away, be as short and as
straight as possible.
When incorporating a rangehood in the design of a kitchen the following points need to be considered
to achieve the most benefit from the rangehood.
1. Ducting from a rangehood carrying the exhaust air, should not exceed a length of three (3) metres.
2. For ducted installation we recommend using galvanised or similar metal type flue pipe. PVC pipe is
not recommended.
3. Ducting containing a 90° degree bend will encounter a loss in efficiency of approximately 35%.
Additional 90° degree bends can cause losses of up to 15% per bend.
4. Ducting size should always comply with the manufacturers specification.
5. We recommend carbon filters be used when re-circulating the air into the room. There will be some
loss of air movement when carbon filters are fitted.
USE AND MAINTENANCE
• It is recommended to operate the appliance prior to cooking. It is recommended to leave the
appliance in operation for 15 minutes after cooking is terminated in order to completely eliminate
cooking vapours and odours. The proper function of the rangehood is conditioned by the regularity
of the maintenance operations, in particular, the active carbon filter.
• The aluminium filters capture the grease particles suspended in the air, and are therefore subject to
clogging according to the frequency of the use of the appliance. In order to prevent fire hazard, it is
recommendable to clean the filter at a maximum of 2 months by carrying out the following in-
structions:
• Remove the aluminium filters from the rangehood and wash them in a solution of water and neutral
liquid detergent, leaving to soak.
• Rinse thoroughly with warm water and leave to dry.
• The aluminium filters may also be washed in the dishwasher. The aluminum panels may alter in
colour after several washes. This is not cause for customer complaint nor replacement of panels.
• The active carbon filters purify the air that is replaced in the environment. The carbon filters are not
washable nor re-useable and must be replaced at maximum every four months. The saturation of the
active carbon filter depends on the frequency of use of the appliance, by the type of cooking and the
regularity of cleaning the anti-grease filters.
• Clean the fan and other surfaces of the rangehood regularly using a cloth moistened with a non
abrasive liquid detergent.
• The rangehood lighting is designed for use during cooking and not for prolonged general illumination
of the environment. Prolonged use of the lighting notably reduces the duration (life) of the bulb.
