Installation
If wall mounting the fan, you will also need:
A 100mm diameter prepared hole.
An appropriate external Wall Grille and Ø100mm wall sleeve duct. Kit Ref 91232AW.
If ceiling mounting the fan, you will also need:
A 100mm diameter prepared hole.
Appropriate ancillaries for termination. These items are available from Xpelair:
1. 3m flexible ducting Ref: 89663AA. If the duct passes through a cold space use insulated duct ref: 89847AA.
2. Soffit Grille Ref: 89742AW
3. XCT100 –Condensation Trap. Ref: 89749AA. Fitted immediately above the fan, this prevents water ingress due to
condensation forming in the duct above the fan and running down.
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 –LVCV4S / LVCV4R
These models are permanently connected to the supply and operation is controlled by a remote switch. They 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/baffle assembly by depressing the latch on the underside of the cover and pulling off the
front cover / baffle from the bottom (See Figure D).
Mark the position of the back-plate
2. Hold the back-plate so that the level line marked on it is orientated horizontally.
3. Carefully insert the fan tube into the wall duct.
4. Mark on the wall the positions of the fixing holes in the back-plate.
5. Remove the back plate from the ducting.
6. Drill screw holes in these positions if necessary, and fit wall plugs and screws as required. The fan may also be fixed
to a wall tube using the clamping brackets. See 10 below.
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 0.5 –1.0mm².
Suitably rated 3-core cable (supply to transformer)
Suitably rated 3-core cable (wiring from transformer to fan).
A wall or ceiling On/Off switch (with indicator light) is recommended
