TIPS FOR EXHAUST DUCT INSTALLATION
The following tips may be considered in order 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 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 installation, make sure that the cooker hood is level to
avoid grease collection at on end.
