Transport bungs are fitted to prevent debris falling into the
unit and causing damage. Premature removal of the
transport bungs may invalidate the guarantee.
1. When the ducting has been installed and you are ready
to connect the unit, remove the transport bungs from
the duct ports.
2. 125mm ducting fits to the outer of the duct ports as
shown.
3. 100mm ducting fits to the inner of the duct ports as
shown.
Ducting best practice
•
The use of flexible ducting must be kept to a minimum
and it should always be pulled taut.
•
If applicable, Fire Dampers
MUST BE FITTED
to duct
work at appropriate locations in accordance with Building
Regulations.
• Ducting must be installed in such a way that resistance
to airflow is minimised.
• Ducting terminals for Inlet and exhaust must be to the
external air outside the building envelope.
• Inlet and exhaust ducts should be separated to ensure
there is no cross contamination of air.
• Ducting in unheated spaces must always be insulated to
prevent condensation forming within the ducting.
