iCON Domestic DC Fans – 15S & 30S
Installation, Maintenance and Use
iCON Domestic DC Fans are available in 2 model sizes and can be fitted into a wall or ceiling.
Each fan requires a suitable size hole through the wall or ceiling which connects into a duct
venting to the outside. The external opening should be covered by a suitable external grill,
available separately from Airflow Developments Ltd.
Model Options
72683701 - 15S -100mm Axial Fan with maximum capacity of 21.9 l/sec.
72683801 - 30S -100mm Mixed Flow Fan with maximum capacity of 34.25 l/sec
iCON Domestic DC Fans can be used as a simple extract fan powered via the SELV power
supply unit (supplied), and connected to either a remote switch, or can be fitted with an
internal control module, supplied to give a range of control options including timer,
humidity, motion sensor, pull cord, trickle speed or a combination of these functions.
Optional control modules are available separately and can be fitted at the time of
installation or retrofitted.
iCON Domestic DC Fans have IPX 4 rated housings, they are double-insulated and are
suitable for fitting in Zone 1 or 2 of bathrooms, toilets, kitchens, utility rooms and inside
shower cubicles as defined in Section 701 BS7161:2008 (IEEE Wiring Regulations, 17th
Edition ). They also comply with the 2010 Building Regulations, Approved Document F. The
power supply unit, supplied with the fan, must be fitted outside of Zones 0, 1 and 2. It is
usually installed outside the room.
Do not place the fan near direct heat sources, e.g. radiant heaters, or where temperatures
can exceed 40°C (104°F).

CONDENSATION TRAP
The power supply unit has resettable over current and short circuit protection. An external
3Amp fuse is still required with each power supply. The power supply unit has a Led
indicator to show that the unit is switched on and functioning correctly.
Note: Switches for fans should be selected and sited in accordance with BS7161:2008
All electrical installation to be carried out by an approved electrician in accordance with Part
“P” U.K. Building Regulations and to the latest IEEE standards, or the appropriate regulations
in the country of installation.
ALWAYS ISOLATE THE POWER SUPPLY UNIT AND FAN UNIT FROM THE POWER SUPPLY
BEFORE REMOVING THE COVER.
Mechanical Installation
Power Supply Unit
The power supply unit does not require dismantling and should be installed by a qualified
electrician to BS7161:2008 (IEEE wiring standards 17th Edition). The maximum length of wire
between the power supply and the fan should not exceed 5m using 1.5mm2 wire.
NEVER COVER THE POWER SUPPLY UNIT WITH THERMAL INSULATION MATERIALS
Fan Unit
iCON Domestic DC Fans can be recessed in a wall or
ceiling. A mounting skirt is provided for surface
mounting of the 30S.
To avoid the backflow of condensation into the fan in
a ceiling installation it is good practice to fit a
CONDENSATION TRAP to the outlet duct of the fan.
Ensure free running of the fan impeller and that
flexible duct connections are not over tightened to
the fan’s outlet spigot.
Airflow recommend that rigid ducting is used instead
of flexible ducting, this will ensure maximum
performance
