iCON FAQs

You can find some of the more commonly asked questions about the Airflow iCON below. If your question is not answered here, please contact us at your earliest convenience.

Iris Questions

The iris is designed to open slowly and takes about 30 seconds to 1 minute to fully open. The actuator for the iris is a wax filled cylinder; when electricity is applied, the wax slowly heats up and expands, which pushes out the piston that moves a lever on the inside of the front cover. This is designed to offer smooth operation with low energy consumption.

The iris is also designed to close slowly. When electricity is no longer supplied, the wax in the actuator slowly cools, the piston retracts, and a spring on the inside of the front cover closes the iris. This can take about 30seconds to 1 minute after no more electricity is supplied.

Answer 1: The actuator clip (the white plastic lever adjacent to the brown actuator unit inside the fan) may be misaligned, bent or broken. Be sure the "foot" on the lower bent lef fits into the notch on the actuator piston (for picture of foot on iCON 15 and 30 click here). If the actuator clip is bent or broken, contact us so we can send you a replacement.

Answer 2: The actuator may not be functioning. Check that the piston extends approximately 1cm after the fan has been running for 1 minute. If the actuator piston does not extend at all, contact us so we can send you a replacement.

Cover Questions

The front cover of the ventilator unit has a bayonet-type fitting. Remove the retaining screw in the front cover using a screwdriver. Rotate the front cover a few desgrees anticlockwise and remove.

When the cover is fixed in place, the iCON logo and the retaining screw on the side of the cover should line up with the pull cord slot on the body of the fan (as shown here)

Installation Questions

In most ceiling installations, taking hot baths and showers will produce hot, humid air that will rise. Once this humid air reaches the cold loft space, it will cool and condense back into water and trickle down the pipe. To help combat water damage, it is good practice to ensure that a condensation trap is fitted to your system. Condensation trap are sold separately from the main unit, please contact us so that you will receive the correct condensation trap for your unit.

Another way to combat water damage is to ensure that the unit's timer (if applicable) is turned up to run on for at least 20 minutes after the fan has been switched off.

iCON is fitted with a double insulated motor and does not require an earth.

iCON fans cannot be fitted through a window.

As per instructions. In the case of an iCON 60, a hole with a diameter of 160mm is needed and then counter bored 190mm to a depth of approximately 75mm.

If Flexi ducting is being used, then it may be that the iCON is catching on the rear impeller.

Ensure that the outlet where the ducting is connect to the rear spigot of the fan is NOT too tight and restricting the impeller movement.

When the light is dimmed, the signal to the trigger on the fan may be too low to set the timer. There may also be a problem with the electronics in the switch and the timer not being compatible. This could result in the failure of the timer, switch or both.

There have been instances when customers have successfully used a dimmer switch without issue, but we do not recommend the use of a dimmer switch with our products.

iCON Module Questions

No. The fan can be wired directly to a remote switch for straight on/off operation or a speed controller on the iCON 30/60 range.

Yes you can, but additional wiring may be required based on what module is fitted.

The humidity setting adjustment needs to be turned up to be less sensitive. For example: adjusted fully anticlockwise = 90% so the fan will NOT switch on until humidity reaches this level. However, if adjusted fully clockwise =40%, the fan will switch on as soon as humidity reaches this level and will run until the humidity level falls below this level.

The live and switched live are incorrect and need to be switched around - switched live needs to be to the T terminal and live to the L terminal.

The fan may run immediately on start-up due to the level of humidity within the room until it reaches its threshold level.

Answer 1: Make sure that the translucent lens cap is fitted to the front cover

Answer 2: Make sure the sensor is within range of movement pick up. The module has a 110o angle pick up at 3 metres.

The switch on the humidity pull cord fan is a momentary switch and does not click. The pull cord just starts the fan running for the time set on the timer. Pulling the cord again only resets the time; it does not turn the fan off.
