AIRFLOW iCON 15S SELV 12V Fan Range User Guide

AIRFLOW iCON 15S SELV 12V Fan Range

Product Information

The iCON SELV 12V DC fans are designed for ventilation in domestic premises and are available in two model sizes: iCON 15S and iCON 30S. These fans are powered by Safety Extra Low Voltage 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).

The iCON SELV 12V Optional Modules are available separately and can be fitted at the time of installation or retrofitted. The optional modules include PCS Pull cord (Manual on/off), PCTS Pull cord timer (Run on timer 1-30 min), DTS Delayed timer (2 min delay, Run on timer 2-45 min, Pull cord), HTS Humidity timer (40-90% RH, Run on timer 2-45 min, Pull cord), PIR timer (Motion sensor, Run on timer 2-45 min), and PRHTS PIR with humidity timer (Motion sensor, 40-90% RH, Run on timer 2-45 min).

The iCON SELV fan range is IPX4 rated and therefore suitable for mounting in bathrooms (including 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 showerhead). 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.

Product Usage Instructions

All electrical installation work must 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 overcurrent 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.

There are different wiring instructions depending on whether there is a control module fitted or not. Wiring and installation of iCON modules can be found in the instructions included within the module packaging. Please refer to page 5 of 16 for wiring instructions for different control modules.

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.

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.

Mechanical Installation

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 practice recommendations.

Wall Installation

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 Installation

Ceiling Recess

The fan should be fitted in the hole, fixed with the screws provided into the support.
The iCON 15S requires a 110mm diameter hole through the ceiling.
The iCON 30S requires a 160mm diameter hole through the ceiling.
Where flexible duct is used the diameter must be maintained.

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.

Best Practice Recommendations

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 maximize 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.

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 through the wall installation fit the duct in an approx. 5° angle down to outside.

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.

Maintenance

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