Installation
For ceiling mounting the fan, you will also need:
A 100mm diameter prepared hole.
A 100mm diameter prepared hole for the external grille, ideally positioned to allow condensation to run away from
the first bend in the duct towards the external grille.
Some suitable insulation for the duct, if the duct passes through a cold space, or use insulated duct ref: 89847AA.
Installing the isolating switch and cables.
1.
Check that the electrical rating shown inside the back-plate matches your mains supply.
2.
Check there are no buried pipes or cables e.g. electricity, gas, water behind the switch location (in the wall or above
the ceiling). If in doubt, seek professional advice.
3.
Isolate the mains supply.
4.
Lay in the cable from the isolating switch to the fan location via the on/off switch (if required).
5.
Lay in the cable from the isolating switch to the point of connection to the mains supply.
6.
Install the isolating switch and on/off switch (if required).
7.
Make all connections within the isolating switch and the on/off switch (if required).
For Australia Only
This model is permanently connected to the supply and operation is controlled by a remote switch. It should be directly wired
to the supply through an approved 10A wall mounted surface switch with at least 3mm clearance between contacts.
Preparing the Fan for installation.
1.
Remove the front cover by depressing the latch on the underside of the cover and pulling off the front cover from the
bottom (See Figure E).
The fan may be fixed in the ceiling using the quick-fix clamping brackets. Tighten the screws until the fan is firmly secured
–
see figure C.
Alternately the fan back-plate can be fixed directly in the ceiling using the screws and wall plugs supplied as described below.
Mark the position of the back-plate (Fig. B)
2.
Hold the back-plate so that the level line marked on it is orientated squarely.
3.
Carefully insert the fan duct into the prepared hole in the ceiling.
4.
Mark the positions of the fixing holes in the back-plate.
5.
Remove the back plate.
6.
Drill screw holes in these positions if necessary, and fit wall plugs and screws as required.
Mount the back-plate.
7.
Feed the mains cable through the cable entry hole in the back plate to the terminals.
8.
Insert the fan duct into the ceiling hole as before.
9.
Fasten the back-plate to the ceiling using appropriate fasteners supplied. See figure B.
10.
If using screws, do not over tighten.
Warning: Do not make any connections to the electrical supply at this stage.
Wet Rooms: On/Off switch must be situated so that it cannot be touched by
persons making use of the bath or shower.
If working above ground floor level, safety precautions must be observed.
A means for disconnection in all poles must be incorporated in the fixed wiring in accordance with wiring
regulations
If metal switch boxes are used, earthing regulations must be followed.
The cross-sectional area of the supply cord used should be ranged from 1-1.5mm².
3 core cable is required.
