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 fulfi lled. 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.
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 suffi cient fl ow of air through the room. Ensure adequate inlets exist through windows,
vents or under the door. Airfl ow 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-diff erentials between the room and outside air will signifi cantly reduce
the exhaust fan’s performance.
6.
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. 1.
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.
7. Unit Orientation:
The unit must be installed to ensure the fan inlet, outlet and ducting are oriented in parallel to any roofi ng structures or supports.
Orientation which forces the unit to be ducted into a 90° bend immediately after the fan inlet/outlet will cause a signifi cant performance reduction.
8. Duct Routing:
As the back pressure increases the unit’s performance is reduced. Airfl ow will be reduced with bends in the duct or squashing of duct. When fi tted, the
inlet & outlet grilles must be lower or same level as inline fan engine. Refer to Fig.1 & 2 below.
The duct can be installed in diff erent ways. Refer to Fig.3 for three types of installation illustration.
9. Vertical ducting with roof vents will result in reduced fan performance, increased noise and condensation/dripping.
The inline fan is designed to extract steam and odour from a bathroom and expel it to the exterior through an eave outlet. It is also suitable for extracting air from one
room and expelling it to another room (heat distribution).
The fan engine is fi tted into the ceiling, well away from the inlet. This inline feature allows the inlet grille to be mounted in wet areas (near the splash zones of bathrooms)
or even above the shower. And because the motor is in the ceiling cavity (away from the inlet grille), noise from the fan is minimal.

2 Things to consider
Note: Lamp kit should not be installed right above the shower. It can be installed in the ceiling outside the shower box.
