HINTS FOR EXHAUST DUCT INSTALLATION
The following rules must be strictly followed to obtain optimal air extraction:
• Keep expansion pipe short and straight.
• Do not reduce the size or restrict expansion pipe.
• When using 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 Rangehood.
• 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 Rangehood is level to avoid grease collection at
on end.
• Ensure the expansion pipe selected for installation complies with relevant standards and is
fire retardant.
