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).
Not where ambient temperatures are likely to exceed 50°C.
If installed in a kitchen fans must NOT be mounted immediately above a cooker hob, or eye level grill.
If installing in a room containing a fuel burning device which has a non-balanced flue, it is the installer's
responsibility to ensure that there is enough replacement air to prevent fumes being drawn down the flue
when the fan is operating up to maximum extract. Refer to Building Regulations for specific requirements.
Exhaust air must not be discharged into a flue used for exhausting of fumes from appliances supplied with
energy other than electric. Requirements of all authorities concerned must be observed for exhaust air
discharge and intake flow rates.
Not suitable for use in possible chemical corrosive atmospheres.
Warning: Do not make any connections to the electrical supply at this stage.
What the installer will need.
3mm electrician’s screwdriver and No.1 or 2 Pozidrive screwdrivers.
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
Where to locate the Transformer.
The transformer can be fixed directly to the wall
The transformer can be sited in a loft or in a convenient position on a wall (not ceiling). The transformer
must not be covered by loft insulation. For wall mounting the transformer must be orientated as shown
in figure B to fulfil ingress protection requirements.
The transformer must not be mounted where ambient temperatures are likely to exceed 40°C.
