airflow across the room (e.g. opposite the internal doorway).
•Near the source of steam or odours.
•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
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.
•When intended for use in possible chemical corrosive atmospheres, consult out Technical Service Department. (For overseas markets contact your local Xpelair distributor).
•DX100PIR Only - Siting must ensure detection of movement. Care should be taken to avoid obstruction that may affect detection beams A .
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 advise.
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).
Note: on/off switch must be situated so that it cannot be touched by persons making use of the bath or shower.
WARNING : DO NOT MAKE ANY CONNECTIONS TO THE ELECTRICAL SUPPLY AT THIS STAGE.
For Australia only (DX100, DX100PC. DX100HP & DX100PIR)
Connection to the supply can be made by a
flexible
For Australia only (DX100T, DX100H & DX100VTD)
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 10amp wall mounted surface switch with at least 3mm clearance between contacts.
WARNING : CHILDREN SHOULD NOT PLAY WITH THE APPLIANCE AND ENSURE THAT YOUNG CHILDREN AND THE INFIRM ARE SUPERVISED
Preparing the hole
If working above ground floor level, appropriate safety precautions must be observed.
WARNING: EYE PROTECTION MUST BE WORN DURING ALL DRILLING AND CHISELLING OPERATIONS.
If installing in a wall
1.Check there are no buried pipes or cables in the wall or obstructions on the outside e.g. electricity, gas, water.
If in doubt, seek professional advise.
2.Mark on the wall the centre of the duct hole.
3.Use this centre to mark a circle to suit the wall duct (115mm diameter).
If core drill equipment is available:
4a.Use as directed by core drill manufacturer.
If core drill equipment is not available: 4b. Drill a centre hole right through the wall.
5.Cut the hole. Do not cut right through the wall. (The recommended method is to drill a series of holes, close together, around the
edge of the cutting line and remove the brick between the holes with a chisel).
6.Go outside and cut a hole in the outer wall, repeating the process described above.
7.Cut ducting to the correct length if required. The wall tube supplied is telescopic and can extend to 300mm maximum.
8.Fit the ducting. Ensure that the duct slopes down away from the fan to allow drainage of any incoming rain water to the outside.
9.Make good the hole. Allow the mortar to set before continuing the fan installation.
If installing in a window or panel
1.Cut a hole, 125mm in diameter or if installing in a window, obtain a ready cut pane.
2.The centre of the hole should be at least 110mm away from the edge of the panel or pane of glass.
If installing in a ventilation shaft
1.Check there are no buried pipes or cables in the ventilation shaft.
If in doubt, seek professional advise.
2.Cut a hole 110mm in diameter, in the side of the shaft.
