fans. Fans are available in two model
sizes and can be fitted to a wall or ceiling.
iCON 15S -100mm axial fan
iCON 30S -100mm mixed-flow fan
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 15).
All electrical installation must be carried out by an approved
electrician in accordance with Approved Document Part P of
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 iCON SELV fan range is IPX4 rated and therefore it is
suitable for mounting in bathrooms (incl. zones 1 and 2), toi-
lets, kitchens and utility rooms, as long as it is not exposed to
water jets (i.e. can be installed
above fixed shower head
).
Switches for fans shall be selected and sited in accordance
with BS7671 (IET Wiring Regulations) or relevant.
Important
Do not place the ventilator near direct heat sources, e.g. radi-
ant heaters,
or where temperatures can exceed 40°C (104°F).
Wiring with no control module fitted:
Recessing fans 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 bored 160mm to a depth of 80mm. The hole
should be lined with a 100mm internal diameter duct.
Surface mounting fans 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.
Optional modules for iCON SELV 12V
Wiring and installation of iCON modules can be found in the
Instructions included within the module packaging.
Wiring for control modules with external switching:
Power Supply Unit (PSU, included in the box)
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 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 1.5mm
2
wire. Never cover the power supply unit with
thermal insulation materials.
iCON fans can be recessed in a wall or ceiling (iCON 30S is
also supplied with surface mounting kit). See pages 8-10 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 11&12 for
best practise recommendations.
Important
Precautions must be taken to avoid the back-flow of gases into
the room from the open flue of gas or other fuel-burning appli-
ances.
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 refit-
ting 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.
