Forspeed andease ofinstallation,your
installationmay require someoftheAncillaries
indicated in “Ancillary Options”.
.
1. Mark on thewall the centreof theduct holeA.
2. Use this centreto cut an opening through the
wall 117mm dia. with aslightfall to the
exterior.
3. Fit thewall tube(not supplied), and motar into
place.
1. Mark on thewall the centreof theduct hole A,
and drill a pilot hole through both walls.
2. Use thecentre to mark arectangular holefor
theinner wall using thedimensionsA.
3. Cut therectangular holethrough theinner
wall.
4. Go outsideand cuta117mm diameterholein
theouterwall using the small holeas the
centre.
5. Measurethe wall thickness.
6. Cut thewall tube (notsupplied), sothat it is
64mm less than thewall thickness.
This method requires a spaceabove the ceiling, such
as aloft orattic,to provideaccess for 100mm
internal diameterducting.
1. Mark on theceiling thecentre of theducthole
A,avoiding ceiling joists andburiedcables
etc.
2. Cut a117mm diameter holeusing the marked
centre.
For 100mm diameter ducting:
This method requires a spaceabove the ceiling, such
as aloft orattic,to provideaccess for 100mm
internal diameterducting.
1. Mark arectangular hole using thedimensions
B.
2. Cut the hole, avoiding ceiling joists and buried
cables etc.
For flat ducting:
•This fan can beinstalledwithin a50mm void
without thecircular spigot ?(Fig. E). Flatducting
adapterkit(FDA) available.
1. Removethefront cover •(Fig. C)
2. Fitthe foamtape supplied around the
circular spigot ?(Fig. E).
3. Removethe electrical cover •(Fig. E). The
impellercan be removedto easeaccess (if
required). This is a push on/pull off assembly.

Thefan mustnot bemountedwhere ambient
temperatures are likely to exceed 40°C.
1. Place the ducting into thehole and align to the
required position. If wall mounting, ensurethat
theducting slopesdownand awayfromthe
fan.
2. Mark the positions of the threefixing holes A
in fan box ?(Fig. E).
3. Ifwall mounting, drill three holes 5.5mm
diameterforwall plugs (supplied).Ifceiling
mounting B,use appropriate fasteners (not
supplied).
4. Cutoutthecable inlethole,if required, inthe
surround ?and slitthecablegrommet. Slide
thesurround ?over the fanbox ?.
5. Pass theelectrical cables intothefan box ?
through therearcable inletholeand surround,
and re-fitthecablegrommet. Ensure that the

6. Offerthefanbox ?uptothewall or ceiling.
Ensurethecircular spigot ?enters the
ducting.
7. Fixthefan box ?tothe wall using screws ?
or to theceiling using appropriatefasteners
(notsupplied).
Thesurround ?is not required. Fitthe ducting to
the circular spigot?.
Ifthe hole size is as recommended:
1. Assemblethe three fan bodyclamps ?to the
fan box ?using screws ?.
2. Slit the cablegrommet. Pass theelectrical
cables into thefanbox ?through thecable
inlet hole and cable grommet.
Ensure cable grommet is inplaceandatight fit.
3. Offer the fan box ?up to thewall.
4. Tighten up thethree screws ?until thefan is
clampedto the innerwall. Thefan body
clamps ?will rotateto an automaticstop
position. DO NOT OVERTIGHTEN.
Ifthehole sizeis largerthanrecommended i.e.
larger thantheflange onthefanbox ?(Mostly
related to“retro-fit” installations):

clip, and fittheclips ensuring correct
alignment.
5. Fit theducting tothe circular spigot?.
6. Offer the fan box ?up to theceiling.
7. Slit the cablegrommet. Pass theelectrical
cable intothe fanbox ?through thefront
cable inlethole.
Ensure cable grommet is inplaceandatight fit.
8. Using the screws 11 (Fig B),fixthefan box
flangeto the ceiling clips.
Fit an outergrille(CF20 variants only)to theouter
wall. Forceiling mounting, useappropriate
ancillaries (notsupplied).
Thetransformer Acan befixed directlyto the wall.
Thetransformercan besitedin aloft or in a
convenientposition on awall (notceiling). The
transformer must not becovered by loft
insulation. For wall mountingthe Fan mustbe
