Location
1. When installing this fan’s ducting through an
external wall, an external wall grille must be fitted
at all times.
2. This fan should be fitted to ducting with a
minimum duct length of at least 500 millimetres
both sides of the fan.
3. Where ducted fans are used to handle moistureladen air, such as a bathroom, a condensation
trap should be fitted in any vertical exhaust ducts.
4. When using flexible ducting, ensure it is pulled
taut. All ducting should be angled towards the
external grille.
5. Ducting passing through cold voids should be
insulated.
6. If the fan and duct extract grille 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.
Wiring

connections. If in any doubt contact a qualified
electrician.
2. These units are for fixed wiring only. A flexible
cord must not be used. All wiring must be fixed
securely and the cable to the fan should be a
minimum of 1mm2 in section. All wiring must
comply with current I.E.E. Regulations or local

Switch off mains supply before making any electrical connections. If in any doubt contact a
qualified electrician.
For any maintenance operation which is not simply cleaning the exterior of the extractor fan, the casing
assembly must be taken out of its housing as indicated in point 1 of the installation instructions. Then the
two reducer tubes (V) must be removed. (see Fig. 3)
To remove casing assembly:
1. Loosen 8 screws (x)
2. Gently separate reduce cones (V) from chassis.
The motor, fan and all the components must be regularly inspected to ensure that they are not dirty nor have
suffered any damage. The frequency will depend on its operating conditions.
During the maintenance sessions remove any dirt collected on the fan blades and the internal parts of the
frame to avoid any imbalance in operation which would lead to a reduction of the aerodynamic qualities and
possible damage to the motor. Never submerge the appliance in water or in any liquid.
Do not use solvents to clean the appliance. The motor bearings need no maintenance.
RATING/SPECIFICATIONS
For all electrical power and IP ratings refer to the fan rating and wiring label.
