Things to consider
3
1. This product shall be installed in accordance to AS/NZS 3000 Wiring Rules.
2. This product is meant for indoor use only.
3. Regulations concerning the discharge of air must be fulfilled. Local building codes may require venting to the outside.
4. Do not locate the inlet grille above a stove. This product is not to be used in conjunction with a kitchen range hood exhaust system.
5. The minimum length of duct between the fan engine and the inlet / outlet grilles is 200mm.
6. Cross Ventilation:
Ventilation products must have an adequate source of external air to ensure rated performance.
Steam and air will only be exhausted through the fan if there is sufficient flow of air through the room. Ensure adequate inlets exist through windows,
vents or under the door. Airflow path from the inlet to the fan should ideally pass over the source of steam or air to be removed from the room.
Restrictions on replacement air entering the room to be ventilated, or pressure-differentials between the room and outside air will significantly
reduce the exhaust
fan’s
performance.
7. Unit location:
The fan engine should be positioned at the highest point on the system so the ducting will slope downwards to both grilles. Refer to Fig. 2.
Do not cover the fan engine with thermal insulation. Keep at least 100mm clearance between the engine and thermal insulation.
The fan engine should not be located in an area containing excessive levels of grease.
When choosing a location for the wall switch, ensure it is not within
arm’s reach
or accessible to a person in a bath or shower.
8. Unit Orientation:
The unit must be installed to ensure the fan inlet, outlet and ducting are oriented in parallel to any roofing structures or supports. Refer to Fig. 1 for
correct installation orientation.
Orientation which forces the unit to be ducted into a 90
°
bend immediately after the fan inlet/outlet will cause a significant performance reduction.
9. Duct Routing:
As the back pressure increases the
unit’s
performance is reduced. Airflow will be reduced with bends in duct or squashing of duct.
When fitted, the inlet & outlet grilles must be lower or same level as inline fan engine. Refer to Fig. 2 and 3.
The duct must not be installed vertically into a roof vent cap - the product is not designed or intended for this type of installation. Refer to Fig.4.
