For speed and ease of installation, your
installation may require some of the Ancillaries
indicated in “Ancillary Options”.
.
1. Mark on the wall the centre of the duct hole A.
2. Use this centre to cut an opening through the
wall 117mm dia. with a slight fall to the
exterior.
3. Fit the wall tube (not supplied), and motar into
place.
1. Mark on the wall the centre of the duct hole A,
and drill a pilot hole through both walls.
2. Use the centre to mark a rectangular hole for
the inner wall using the dimensions A.
3. Cut the rectangular hole through the inner
wall.
4. Go outside and cut a 117mm diameter hole in
the outer wall using the small hole as the
centre.
5. Measure the wall thickness.
6. Cut the wall tube (not supplied), so that it is
64mm less than the wall thickness.
This method requires a space above the ceiling, such
as a loft or attic, to provide access for 100mm
internal diameter ducting.
1. Mark on the ceiling the centre of the duct hole
A, avoiding ceiling joists and buried cables
etc.
2. Cut a 117mm diameter hole using the marked
centre.
For 100mm diameter ducting:
This method requires a space above the ceiling, such
as a loft or attic, to provide access for 100mm
internal diameter ducting.
1. Mark a rectangular hole using the dimensions
B.
2. Cut the hole, avoiding ceiling joists and buried
cables etc.
For flat ducting:
• This fan can be installed within a 50mm void
without the circular spigot ? (Fig. E). Flat ducting
adapter kit (FDA) available.
1. Remove the front cover • (Fig. C)
2. Fit the foam tape supplied around the
circular spigot ? (Fig. E).
3. Remove the electrical cover • (Fig. E). The
impeller can be removed to ease access (if
required). This is a push on/pull off assembly.
LVCF20 / LVCF20T Only (Fig. D)
4. The correct condensation control speed should
be selected to suit the room size in which the
fan is to be installed. Slide the switch X to the
required position. Please note that the fan is
factory set to “Position 2”.
5. Switch Position Size / Room Volume (m³)
1 Large (34 and above)
2 Medium (28 – 34)
3 Small (less than 28)
LVCF20 / LVCF20T Only (Fig. D)
6. The fan can be set so that it provides constant
trickle extraction. Slide the switch Y to the
required position. Please note that the fan is
factory set to “Position 0”.
7. Switch Position Setting
0 Trickle extraction OFF
1 Trickle extraction ON
LVDX200T / LVCF20T Only (Fig. D)
8. The fan can be set so that there is a 2-minute
delayed start to its operation when used with
an external on/off switch. Slide the switch Z to
the required position. Please note that the fan
is factory set to “Position 0”
9. Switch Position Setting
0 Time delay start OFF
1 Time delay start ON
The fan must not be mounted where ambient
temperatures are likely to exceed 40°C.
1. Place the ducting into the hole and align to the
required position. If wall mounting, ensure that
the ducting slopes down and away from the
fan.
2. Mark the positions of the three fixing holes A
in fan box ? (Fig. E).
3. If wall mounting, drill three holes 5.5mm
diameter for wall plugs (supplied). If ceiling
mounting B, use appropriate fasteners (not
supplied).
4. Cut out the cable inlet hole, if required, in the
surround ? and slit the cable grommet. Slide
the surround ? over the fan box ?.
5. Pass the electrical cables into the fan box ?
through the rear cable inlet hole and surround,
and re-fit the cable grommet. Ensure that the
cable grommet is in place and a tight fit.
6. Offer the fan box ? up to the wall or ceiling.
Ensure the circular spigot ? enters the
ducting.
7. Fix the fan box ? to the wall using screws ?
or to the ceiling using appropriate fasteners
(not supplied).
The surround ? is not required. Fit the ducting to
the circular spigot ?.
If the hole size is as recommended:
1. Assemble the three fan body clamps ? to the
fan box ? using screws ?.
2. Slit the cable grommet. Pass the electrical
cables into the fan box ? through the cable
inlet hole and cable grommet.
Ensure cable grommet is in place and a tight fit.
3. Offer the fan box ? up to the wall.
4. Tighten up the three screws ? until the fan is
clamped to the inner wall. The fan body
clamps ? will rotate to an automatic stop
position. DO NOT OVERTIGHTEN.
If the hole size is larger than recommended i.e.
larger than the flange on the fan box ? (Mostly
related to “retro-fit” installations):
1. The fan body clamps ARE NOT suitable.
Construct a wooden frame of INTERNAL
dimensions 203 x 233mm. Depth should be at
least 50mm. Fit the wooden frame into the
internal wall and make good the hole.
2. Offer the fan box ? up to the wall.
3. Screw the fan box ? to the wooden frame
using the slots in the flange (screws not
supplied).
1. The surround ? is not required.
2. Insert the fan box ? into the hole and mark
four positions using the slots in the flange B.
3. Remove the fan box ? from ceiling and fit the
four ceiling clips (supplied) over the edge of
the hole, so that the clips align with the marks
on the ceiling B.
4. Drill 4 pilot holes into the ceiling through the
hole of each clip, ensuring not to damage the
clip, and fit the clips ensuring correct
alignment.
5. Fit the ducting to the circular spigot ?.
6. Offer the fan box ? up to the ceiling.
7. Slit the cable grommet. Pass the electrical
cable into the fan box ? through the front
cable inlet hole.
Ensure cable grommet is in place and a tight fit.
8. Using the screws 11 (Fig B), fix the fan box
flange to the ceiling clips.
Fit an outer grille (CF20 variants only) to the outer
wall. For ceiling mounting, use appropriate
ancillaries (not supplied).
The transformer A 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 Fan must be
orientated as shown in H to fulfil ingress
protection requirements.

4. THESE APPLIANCES ARE INTENDED FOR CONNECTION TO FIXED WIRING.
5. CHECK THAT THE ELECTRICAL RATING SHOWN ON THE TRANSFORMER MATCHES THE MAINS SUPPLY.
6. SITE BOTH FAN AND TRANSFORMER AWAY FROM DIRECT SOURCES OF HEAT (I.E. GAS COOKERS OR EYE LEVEL
GRILLES. THE FAN MUST NOT BE MOUNTED WHERE AMBIENT TEMPERATURES ARE LIKELY TO EXCEED 40ºC. THE
TRANSFORMER MUST NOT BE MOUNTED WHERE AMBIENT TEMPERATURES ARE LIKELY TO EXCEED 40ºC.
7. WHEN THE FAN IS INSTALLED IN A ROOM CONTAINING A FUEL BURNING APPLIANCE, THE INSTALLER MUST ENSURE
THAT AIR REPLACEMENT IS ADEQUATE FOR BOTH THE FAN AND THE FUEL BURNING APPLIANCE.
8. ENSURE THAT ALL RELEVANT SAFETY PRECAUTIONS (CORRECT EYE PROTECTION AND PROTECTIVE CLOTHING ETC)
ARE TAKEN WHEN INSTALLING, OPERATING AND MAINTAINING THIS FAN.
9. GENERAL GUIDANCE FOR SITING THE FAN SEE “FIG.G”. ALWAYS SITE FAN AS HIGH AS POSSIBLE.
10. IF ANY SECTION OF THE DUCTWORK IS POSITIONED HIGHER THAN THE FAN A CONDENSATION TRAP (XCT100) MUST BE
FITTED AS CLOSE AS POSSIBLE TO THE FAN.
11. THIS APPLIANCE IS NOT INTENDED FOR USE BY YOUNG CHILDREN OR INFIRM PERSONS WITHOUT SUPERVISION. YOUNG
CHILDREN SHOULD BE SUPERVISED TO ENSURE THEY DO NOT PLAY WITH THE APPLIANCE.
