13. If you are using the expansion pipe/have an outlet, attach the expansion pipe
with the cable tie to the outlet of the cooker hood. NOTICE:
• The expansion pipe is not needed when you use the active carbon filter.
• Keep expansion pipes short and straight.
• Do not reduce the size of the expansion pipe.
• When using an expansion pipe, always install the pipe pulled out to
minimize pressure loss.
• Failure to observe these instructions will reduce the performance and
increases noise levels of the cooker hood.
• Do not connect the ducting system of the cooker hood to any existing
ventilation system that is being used for any other appliance.
• The angle of the bend of the expansion pipe should not be less than 120º.
• Make sure that the expansion pipe complies with relevant standards and is
fire retardant.
• Level the cooker hood after installation to avoid grease collection at one
end.
