SELV 12V Fan Range
Installation and Operating Guide
Fan Dimensions
Page 2 of 16
iCON SELV 12V DC fans are designed for ventilation domes-
tic premises and available in two model sizes. They are powered Safety Extra Low Voltage fans and can be fitted to a
wall or ceiling.
The iCON SELV range can be used as a simple extract
SELV fan operated by a remote switch (standard), or can
be fitted with an internal control module to give a range of
control options (which includes: timer, humidity, motion sensor,
pull cord or combinations of these functions).
These optional modules are available separately and can be
fitted at the time of installation or retrofitted (see page 6).
All electrical installation work to be carried out by an approved
competent person in compliance with U.K. Building Regulations and to the latest IET standards, or the appropriate regulations in the country of installation.
The fan requires a 12V DC supply (included in the box),
class III equipment (marked as stated in BS EN 60417).
The power supply unit requires 100-240V 50/60Hz supply
(class II). It is self resetting for over current and short circuit
protection. An external 3A fuse and 30mA RCD is required for
each unit. The LED indicator shows the unit is switched on
The iCON SELV fan range is IPX4 rated and therefore it is
suitable for mounting in bathrooms (incl. zones 1 and 2), toilets, kitchens and utility rooms, as long as it is not exposed to
water jets (i.e. can be installed above fixed shower head).
The power supply unit must be fitted outside of wet zones
(usually outside of the room). The maximum length of wire
between the unit and the fan should not exceed 5 meters
using 1.5mm2 wire. Never cover the power supply unit with
thermal insulation materials.
Important
Do not place the ventilator near direct heat sources, e.g. radiant heaters, or where temperatures can exceed 40°C (104°F).

iCON fans can be recessed in a wall or ceiling (iCON 30S is
supplied with surface mounting kit). See pages 9 -11 for
details.
Always ensure free running of the fan impeller and that duct
connections are not over tightened to the fan outlet spigot.
Fix the sealed grommet supplied into the cable entry hole.
Pierce the grommet to allow the mains cable to be pulled
through while maintaining the integrity of the seal.
Airflow Developments recommends that rigid ducting is used
where possible instead of flexible ducting, this will ensure
maximum performance.
Before carrying out the installation see pages 12 & 13 for
best practise recommendations.
To remove front cover assembly, first make sure the fan is
off, isolated from the power supply and the iris shutter is
fully closed.
1. Undo the locking screw at the bottom edge of the cover
using a screwdriver.
2. Rotate the cover a few degrees anticlockwise until it clicks
out from the fittings.
3. Remove the cover by pulling it out.
To refit the cover, reverse the above procedure. If when refitting the front cover the iris stays open, remove the cover and
don’t attempt to refit it for approx. two minutes (allowing the
actuator to retract back in the closed position). Then try again.

Recessing fan in the wall
The iCON 15S requires a 110mm diameter hole through the
wall lined with a 100mm internal diameter duct.
The iCON 30S requires a 110mm diameter hole through the
wall, counter board 160mm to a depth of 80mm. The hole
should be lined with a 100mm internal diameter duct.
Surface mounting fan on the wall
When surface mounting the iCON 30S the supplied mounting
skirt should be used.
The iCON 30S requires a 110mm diameter hole through the
wall lined with a 100 mm internal diameter duct.
Ensure all vapour barriers are properly restored.
Ceiling Surface Mounting
When surface mounting the iCON 30S, the mounting skirt
provided should be used. The mounting skirt should be fixed,
with the screws provided, into the support. The fan is then
fitted into the skirt.
The iCON 30S requires a 110mm diameter hole through the
ceiling.
When recessing or surface mounting in the ceiling, a plywood
support (min. 18mm thick) must be mounted between the
ceiling joists. Any fixing screws should be fitted through the
plaster board into the support.
Measurements and Commissioning
The Building Regulations 2010, imposes a requirement that
testing and reporting of mechanical ventilation performance
(see Approved Document F1) is conducted in accordance with
an approved procedure.
Compliance with this requirement by an assessed and registered ‘Competent Person’ should follow a ‘Best Practise’ process and adopt air flow measurement, Method A - The Unconditional Method - using a suitable UKAS certified measuring
instrument. Generically referred to as ‘Zero Pressure Air Flow
Meter’ or ‘Powered Flow Meter’.
Further information on this method is detailed in NHBC Building Regulations Guidance Note G272a 10/13 and BSRIA
Guide document BG 64/2016.
Installation with flexible ducting
Where flexible ducting is used the diameter must be maintained and it is good ventilation practice that the ducting is
extended to a minimum of 90% its possible length in order to
maintain the best possible air flow.
Ensure that flexible duct connections are not over tightened to
the spigots.
To maximise the air flow rigid ducting should be used where
possible. The fan and ducting should be installed in accordance with the requirements of the Domestic Ventilation Com-
pliance Guide, part of the Building Regulations.
SAFETY FIRST: ALWAYS ISOLATE THE FAN UNIT FROM
THE POWER SUPPLY BEFORE DOING ANY WORK ON
THE FAN/MODULE.
When installed according to these instructions the iCON range
is completely safe. The materials used do not constitute a
hazard.
Cleaning
Fan and ducting should be inspected and cleaned on a
regular basis to keep fan performance. The external hous-
ing of the fan can be wiped with a damp cloth. Do not use
household cleaners containing abrasives. Cleaning of the
internal parts such as the impeller should be carried out by
using a soft brush. Never clean any parts of the fan assembly
by immersing in water or using a dishwasher.
Warning
This appliance can be used by children aged from 8 years and
above and persons with reduced physical, sensory or mental
capabilities or lack of experience and knowledge if they have
been given supervision or instruction concerning use of the
appliance in a safe way and understand the hazards involved.
Children should not play with the appliance. Cleaning and user
maintenance shall not be carried out by children without adult
supervision.

the vertical outlet duct of the fan.
With through the wall installation fit the duct in an approx.
5° angle down to outside.
