What the installer will need
• A means for disconnection in all poles must be incorporated in the fixed wiring in
accordance with wiring regulations (wall or ceiling mounted).

•
If metal switch boxes are used, earthing regulations must be followed.
• Suitably rated 2-core cable – DX100B / DX100BP / DX100BHPT
• Suitably rated 3-core cable – DX100T/ DX100BHT
• 3mm electrician’s screwdriver and No.1 or 2 Pozi drive screwdrivers.
• A wall or ceiling on/off switch – DX100T/ DX100BHT.
It is recommended to use a switch with an indicator light.
• Junior hacksaw (if installing in a window or panel less than 16m thick).
If wall mounting the fan, you will also need
• An appropriate Wall Kit including telescopic wall tube and back draught shutter.
• Alternatively, an appropriate Wall Grille and ƒ100mm ducting.
• A masonry drill, hammer & chisel (or core drill equipment if available).
• Mortar to make good the hole around the ducting.
If window/panel mounting the fan, you will also need
• An appropriate Glass fixing Kit.
• You will need a window pane between 3mm and 6mm thick (preferably 4mm).
• Do not install in glass 3mm thick if the windowpane area is more than 0.2sq.m.
•
If installing in sealed double glazing, a specially manufactured unit should be
obtained from the glazing manufacturer, you will also require a special kit, Xpelair Cat.
ref.DXBDG.
•
If installing in sash windows, you should mount the fan in the upper window. Secure
the upper sash in the closed position and fit stops just below the level of the fan, to
prevent damaging it when the sash is raised.
• If installing in a panel which is between 9mm and 46mm thick, you will need a special
kit, Xpelair Cat. ref. DXBDG. Do not install these fans in a panel which is more than
46mm thick.
•
To prevent a possible hazardous situation from water ingress, an appropriate
condensation trap must be fitted as close as possible to the fan in all situations
where any section of the duct work is positioned higher than the fan itself.
Where to locate the 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 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.
•
When intended for use in possible chemical corrosive atmospheres, consult
out Technical Service Department. (For overseas markets contact your local
Xpelair distributor).
Installing the isolating switch and cables
1. Check that the electrical rating shown inside the backplate matches your
mains supply.
2. It is intended that this product is directly wired to a fixed outlet.
3. If no supply is readily available it will be necessary to install this wiring. This should
be done by a qualified electrician.
4. It is acceptable to use the lighting circuit ring main for this product.
5. A suitable isolating switch will required, which must be situated so that it cannot be
touched by persons making use of the bath, shower, or hand basin.
6. It is recommended an on/off switch is installed as well as the isolating switch.
7. Only when this wiring is in place should you proceed with the installation.
Preparing the hole
If working above ground floor level, 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. The centre of the hole should be at
least 110mm away from the edge of the mounting surface.
3. Use this centre to mark a circle to suit the wall duct (ƒ115mm).
I
f 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. (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 above.
7. Cut ducting to the correct length if required.
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 advice.
2. Cut a hole ƒ110mm, in the side of the shaft.
3. If the shaft has cavity wall, use the wall tube to bridge the cavity.
4. Fit ducting and condensation trap if necessary, positioning condensation trap as
near to the fan as possible.
If installing in a ceiling
1. Check there are no buried pipes or cables in the ceiling/joists etc.
If in doubt, seek professional advice.
2. Cut a hole ƒ115mm.
Preparing the fan for installation
Remove the front cover by pressing the release catches located on the sides of the
unit with a 3mm screwdriver, whilst pulling the front cover forward (fig. G).
Mount the fan in the hole
If working above ground floor level, safety precautions must be observed.
If installing in a wall, ceiling or vent
Mark the position of the backplate (fig A).
1. Hold the backplate so that the terminal block faces you in the top left hand corner
and the lip points towards the hole.
2. Carefully insert the lip into the wall duct/ceiling or vent shaft.
3. Adjust the position of the backplate until it is level.
4. Mark on the wall/ceiling or vent shaft the positions of the four fixing holes in the
backplate.
5. Remove the back plate from the ducting.
6. Drill screw holes in these positions if necessary, and fit wall plugs if necessary.
Mount the backplate (fig B).
1a. If installing in a vent, an appropriate Vent Kit is required.
1b. If installing in a ceiling, appropriate termination ancillaries are required.
Follow instructions provided.
2. If wiring the fan from behind, remove knockout. Feed the mains cable through the
cable entry hole in the back plate to the terminals (fig. C).
3. If wiring from above, leave the cable free to be fitted into labyrinth.
4. Insert the lip of the backplate into the wall duct/ceiling or vent shaft as before.
5. Fasten the backplate to the wall/ceiling or vent shaft using appropriate fasteners.
If using screws, do not over tighten.
6. If installing in a wall, an appropriate Wall Grille is required.
Follow instructions provided.
If installing in a window or panel
1. If installing in a window or panel no more than 9mm thick, an appropriate Glass
Kit is required. Follow instructions supplied.
Cutting back the Spigot (if required)
If installing in a window or panel less than 16mm thick, the fan spigot needs to be
cut back to the visible step 20mm away from the rear of the back plate.
1. Remove the impeller by pulling it forward
2. Cut the spigot back to the step using a junior hacksaw, ensuring that the motor
shaft is not marked by the hacksaw.
3. Remove any burrs from the edge of the spigot.
4. Refit the impeller by locating it onto the shaft and pushing it on fully.
