INSTALLATION REQUIREMENT
•A licensed electrician is required to install this unit to the mains supply.
•Before installation, check the installation location in the ceiling has access to a socket outlet which is
connected to a wall switch. If it does not, please contact a licensed electrician to arrange installation of the
socket outlet and wall switch before continuing. Refer to the circuit diagram section for more information.
(Fig.4)
•All wiring and installation of the exhaust fan must adhere to the local council regulation and latest local
and national wiringrules, eg. AS/NZS 3000electrical installations. If unsure, contact a licensed electrician.
•This is a Class I product and must be earthed.
•This product is suitable for indoor use only.
•This product must be installed at least 2.1 m above the floor level.
•Before cutting a hole in the ceiling, check that there are no ceiling joists, etc. or electrical wiring above the
desired mounting location.
•The mounting point must be able to support at least 2 times the weight of the exhaust fan.
•Ensure all the clearance values to the structural building element are maintained according to the
clearance diagram in Figure 2.
•Do not install the exhaust fan in canopies over stoves etc., as excessive heat will damage the product.
•This product is designed for installation in the flat ceiling only. Do not mount it on a sloping ceiling or a
vertical wall.
•Any duct (not included) attached to the product must be installed horizontally in the ceiling and with the
same height or lower than the exhaust fan.
•Ensure the duct (not included) is not bent otherwise the performance will be reduced.
•Where applicable, precautions must be taken to avoid the back-flow of gases into the room from the open
flue of gas or other fuel-burning appliances.
•Do not allow any thermal insulation to cover any part of the rear of the appliance.
•Ensure the thermal insulation does not obstruct the airflow.
•There must be an adequate source of external air to ensure the rated performance.
•For exhaust fan optimum performance, volume of air being extracted should be equal to the amount of air
entering the room. Air is drawn mostly from under a door, or an open window. If the bathroom or room is
air tight (door and windows shut), the exhaust will not perform well.
