Airflow 12v iCON SELV and iCON eco S Domestic Fan

Installation, Maintenance and Use

iCON SELV (Safety Extra Low Voltage) and iCON eco S fans are available in 2 model

izes and can be fitted to a wall or ceiling. Each fan requires a suitable size hole through

s
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..

he iCON SELV and iCON eco S range can be used as a simple extract fan powered via

T

he SELV transformer unit, and connected to either a remote switch, or can be fitted with

t
an internal control module, supplied to give a range of control options including timer,
humidity, motion sensor, pull cord, trickle speed or combinations of these functions.

ptional modules are available separately and can be fitted at the time of installation or

O
retrofitted.

The iCON SELV and iCON eco S fans have IP X4 rated housings, they are double­insulated 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, Seventeenth Edition ). The iCON SELV and iCON eco S also complies with
the Building Regulations, Approved Document F. The transformer 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).

The iCON SELV transformer unit has a thermal protection device internally fitted, and an
external 3A fuse is required for each transformer unit; therefore no internal fuse is fitted to
the fan unit.

The iCON eco S power supply has resettable over current and short circuit protection. An
external 3Amp fuse is still required with each power supply. The eco S (power supply) has
a Led indicator to show that the unit is switched on and functioning correctly.

he transformer requires a 230V 50Hz single phase supply and has a 12V dc output for

To avoid the backflow of condensation into the
fan in 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 outlet spigot.

To avoid reduced flow, an elbow plenum should
be used for all installations which contain

ending of ducting.

Recessing iCON SELV/iCON eco S Fans in Wall

The iCON 15 SELV and iCON eco15S requires a 110mm diameter hole through the wall
lined with a 100mm id (internal diameter) duct.
The iCON 30 SELV and iCON eco30S requires a 110mm diameter hole through the wall,
counter bored 160mm diameter to a depth of 75mm. The 110mm hole should be lined with
a 100mm id duct.

Surface Mounting iCON SELV/iCON eco S Fans on Wall

When surface mounting the iCON 30 SELV and iCON eco30S the supplied mounting skirt
should be used.

Cleaning

• The external housing 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 using a soft
brush.
Note: Always ensure that the fan unit is isolated from the power supply before inserting the
brush into the impeller duct.

• Never clean any parts of the fan assembly by immersing in water or using a dishwasher.
