HINTS FOR EXHAUST DUCT INSTALLATION
The following r
ules must be strictly followed to obtain optimal air extraction:
• Keep ex
pansion pipe short and straight.
• Do not reduce the size or restrict the expansion pipe.
• When using the expansion pipe always install the pipe pulled taut to minimize pressure
loss.
• Failure to observe these basic instructions will reduce the performance and increase
noise levels of the cooker hood.
• Any installation work must be carried out by a qualified electrician or competent person.
• Do not connect the ducting system of the hood to any existing ventilation system which
is being used for any other appliance ,such as warmer tube, gas tube , hot wind tube.
• The angle of the bend of the expansion pipe should not be less than 120º; you must
direct the pipe horizontally, or, alternatively, the pipe should go up from the initial point
and should be led to an outer wall.
• After the installation ,make sure that the cooker hood is level to avoid grease collection
at on end.
• Ensure the expansion pipe selected for installation complies with relevant standards
and is fire retardant.

afety reason, please use only the same size
