earth connection.
5. The fan should not be accessible to a person using
either the shower or the bath.
Location
1. When installing fan through an external wall, an
external wall grille must be fitted at all times.

fitted as high on the wall as possible, or if
preferred, on the ceiling. Note: Pullcord models
should not be installed in a ceiling.
3. Do not install the unit within a shower cubicle
or anywhere else where there is a risk of being
sprayed with water (Please see our range of
showerfans for these installations.).
4. If the fan is installed in a room containing a fuel
burning appliance, the installer must ensure that
the air replacement is adequate for both the fan
and the fuel burning appliance.
COMTK Series
1. Cut a hole through the wall to suit fan type. See diagram below and dimensions D&E
2. Fit the telescopic sleeve into the wall. The sleeve is adjustable and suitable for cavity or solid walls. ( A longer extension
sleeve is available to order) Make sure there is a slight tilt to the outside to allow any water which may get in through the
outside grille, drain to the outside.
IMPORTANT Ensure a minimum 300mm of power cable is passed through the cable entry for the electrical
connections.
3. Build in the sleeve and make good around the edges. The external and internal grilles have a flange that over hangs the
sleeve.

most makes of sleeve and wall box with little or no modifications to the existing wall box installations. See Diagram 2 for
dimensions.
5. All models of the series are secured internally by 4 mounting screws, and secured externally by 4 mounting Screws. After
fixing the front and rear sections ensure you insert the hole plugs provided.
