Fan dimensions
Range overview
Airflow® iCON® 230V fans are available in three model sizes and can be fitted to a wall or ceiling.
iCON 15 -100mm axial fan
iCON 30 -100mm mixed-flow fan
iCON 60 -150mm mixed-flow fan
The iCON range can be used as a simple extract 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.
Electrical installation
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 230V 50Hz single phase supply, class II equipment (marked as stated in BS EN 60417). An external 3A fuse and a 30mA RCD is required for each fan unit.
The iCON 230V 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).
All wiring and switches for fans shall be selected and sited in accordance with BS7671 (IET Wiring Regulations) or relevant.
Do not place the ventilator near direct heat sources, e.g. radiant heaters, or where temperatures can exceed 40°C (104°F).

Wiring and installation of iCON modules can be also found in the Installation an Operation Guide included within the module packaging (optional, see www.airflow.com for details).
Mechanical installation
iCON fans can be recessed in a wall or ceiling (iCON 30 and 60 are also supplied with surface mounting kit). See pages 810 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.
Precautions must be taken to avoid the back-flow of gases into the room from the open flue of gas or other fuel-burning appliances.
Front cover removal
To remove front cover assembly, first make sure the fan is off, isolated from the power supply and the iris shutter is fully closed.
- Undo the locking screw at the bottom edge of the cover using a screwdriver.
- Rotate the cover a few degrees anticlockwise until it clicks out from the fittings.
- 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.
Fitting on the wall
Recessing fans in the wall
The iCON 15 requires a 110mm diameter hole through the wall lined with a 100mm internal diameter duct.
The iCON 30 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.
The iCON 60 requires a 160mm diameter hole through the wall, counter bored 190mm to a depth of 80mm. The hole should be lined with a 150mm internal diameter duct.
Surface mounting fans on the wall
When surface mounting the iCON 30 and iCON 60 the supplied mounting skirt should be used.
The iCON 30 requires a 110mm diameter hole through the wall lined with a 100 mm internal diameter duct.
The iCON 60 requires a 160mm diameter hole through the wall lined with a 150 mm internal diameter duct.
Ensure all vapour barriers are properly restored.
Fitting in the ceiling
When recessing or surface mounting fans in the ceiling, a plywood support (min. 18mm thick) should be mounted between the ceiling joists. Any fixing screws should be fitted through the plaster board into the support.
Fans should not be fitted to unsupported plaster board.
Recessing fans in the ceiling
The fan should be fitted in the hole, fixed with the screws provided into the support.
The iCON 15 requires a 110mm diameter hole through the ceiling.
The iCON 30 requires a 160mm diameter hole through the ceiling.
The iCON 60 requires a 190mm diameter hole through the ceiling.
Where flexible duct is used the diameter must be maintained.
Surface mounting fans on the ceiling
When surface mounting the iCON 30 and iCON 60, 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 30 requires a 110mm diameter hole through the ceiling.
The iCON 60 requires a 160mm diameter hole through the ceiling.
Where flexible duct is used the diameter must be maintained.
Best practice recommendations
Condensation
To avoid the backflow of condensation into the fan in ceiling installations it is good practice to fit a condensation trap to the vertical outlet duct of the fan. With thru-the-wall installation fit the duct in an approx. 5° angle down to outside.
Measurements and commissioning
The Building Regulations 2010, Statutory Instrument Part 9, §42, 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 Compliance Guide, part of the Building Regulations.
