Installation Manual
3.2 Surface Mounting
Remove the fan from the box, taking care to dispose of the packing
material properly.
Check the location of existing wiring for ease of connection and that
the voltage and frequency correspond with those marked on the fan
rating label.
For optimum performance site the fan a minimum of 2.3m above
ground level and should be away from a heat source (e.g. a heater), any
direct light (sunlight, lamp etc.) or any air conditioning unit. Take care
to ensure that the sensor (PIR unit) is free of any obstruction (such as a
cupboard).
LV models must be installed using the remote transformer, which
should be sited outside the scope of any water source (see current IEE
Regulations for guidance).
The fan must not be used in an ambient temperature higher than 40°C.
Before fixing the fan to the wall/ceiling, decide whether to have the
cable entering the fan through the knocked-out hole on the top of the
Motor Fan Assembly or through the back of the Motor Fan Assembly.
In the first case the included cable clamp and grommet will need to be
used. In the second option the cable entry hole will need to be knocked
out.
Use the appropriate size core cutter to obtain a hole diameter of
100mm or 150mm in the wall/ceiling allowing if necessary for the
thickness of any ducting to be used.
The fan must not be exhausted into a duct which is already used for any
other purpose (see Approved Document F1 2006 for guidance).
Dismantle the fan:
•Remove the front cover (1) by unscrewing front fixing screw (4).
•Using the Motor Fan Assembly (3) of the fan as a template, mark
the hole drilling positions to fix the fan to the wall or ceiling.
•Drill the fixing holes and using the wall plugs and long screws
provided, fix the Motor Fan Assembly (3) to the wall/ceiling.
With the front cover removed connect the mains supply cable to the
terminal block then replace front cover of the fan.

4.1 Electrical Information
It is recommended that the installation be carried out by a qualified
electrician. All electrical connections must comply with current IEE
wiring regulations. The fan is a fixed appliance, and the electrical supply
must therefore be by a fixed wired and fused (3 amp) spur incorporating
a double or triple pole switch with contact openings of at least 3mm.
Use twin conductor cable of at least 1mm3in section (Figure 9).

Installation Manual
The fan is double insulated and does not require earthing. The
fan complies with current electrical safety regulations, including
Electromagnetic Compatibility (EMC) Directive 2014/30/EU and Low
Voltage Directive (LVD) 2014/35/EU.
The fan must not be used as a switch for water heaters, stoves etc.
The printed circuit board in these fans has been protected to make
it compatible with the majority of fluorescent light fittings available
on the market today. However, it is impossible to be aware of all new
products introduced. We suggest, therefore, that you contact your
supplier to establish the compatibility of any fluorescent light fittings
you intend to use.
