Where to locate it
Fan
•Locate it as high as possible.
•At least 110mm from the edges of the mounting surface to the centre of the hole.
•As far away as possible from and opposite to the main source of air replacement to ensure 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
•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 our Technical Service Department.
(For overseas markets contact your local Xpelair distributor).
•LV100PIR Only - Siting must ensure detection of movement. Care should be taken to avoid any obstructions that may affect detection beams A .
Transformer
•In a loft or any convenient position on a wall (not suitable for ceiling mounting).
The transformer must not be covered by loft insulation.
•Must be positioned the correct way up to fulfil ingress protection requirements.
•Not within 0.6m of a bath or shower cubicle, up to a height of 2.25m.
•Not where ambient temperatures are likely to exceed 50˚C.
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 supply to the double pole isolating switch.
5.Lay in the cable from the isolating switch to the transformer location.
6.Lay in the cable from the transformer to the fan location.
7.Install the isolating switch.
8.Make all connections within the isolating switch.
Note: On/off switch must be so situated 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.
Preparing the hole for the fan
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 advice.
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, cut from both sides. (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. Allows the Mortar to set before continuing the fan installation.
If installing in a window or panel
Cut a hole, 125mm in diameter. The centre of the hole should be at least 110mm away from the edge of the panel or pane of glass. It is recommended that you obtain a ready cut pane for window installation.
