iCONstant | 197 | 120 | 70 | 100 | 50 |
The iCONstant range consists of timer and humidity/timer variants. They are designed for use in any wet room. Trickle flows rates of 6, 8 or 13 l/s can be activated on installation. Boost flow rates are selected by pull cord, external switch or humidity sensor (HT model only). The iCONstant range is IPX5 rated and suitable for use in Zone 1 of a wet room.
Remove front cover.
Remove back plate cover.
Using the template provided, mark and drill a spigot hole to suit 100mm diameter rigid ducting. Make provision for the electrical supply cable. Fit wall plugs provided.
Mount fan into the spigot hole ensuring cable is fed through the cable grommet provided. Position alignment arrow vertically. Fix to wall or ceiling with the 4 screws provided.
All electrical installation to be carried out by an approved electrician in accordance with Part "P" U.K. Building Regulations and to the latest IEEE standards, or the appropriate regulations in the country of installation. iCONstant fans require a 90-264V 50/60Hz supply, it is double insulated so therefore does not require an earth. Fans installed in Zone 1 or Zone 2 must be at least IPX4 (splash proof) rated. Additionally, fans installed in Zone 1 must be SELV (Safety Extra Low Voltage) or IPX5 (jet proof) rated. The iCONstant range is IPX5 rated and suitable for use in Zone 1.
Secure supply wires into the terminal block. L—Live, N-Neutral and T—switched live (optional). Secure AC mains cable to main body of fan with cable clamp supplied.
Fit back plate cover.

On connection to the power supply the fan will run a diagnostic sequence. This is indicated by the LED flashing 6 times. The fan will automatically start. |
To adjust the airflow rate on commissioning, press top button to increase flow rate, press bottom button to decrease flow rate.
Fit electronics cover and secure with the 2 fixing screws. Check the fan is running. If the LED is on permanently check installation for impeller obstructions and resolve. Replace the front cover and twist clockwise to secure.
Automatic Humidity Control with a progressive increase in humidity—the fan will boost when the pre-set value (factory setting 70-80% RH) is reached. However, when the sensor detects a rapid increase in humidity the fan will boost automatically before the pre-set value has been reached so that preventive ventilation commences. The fan reverts to trickle automatically when the humidity is reduced to 10% below the set point. Note: It is possible that a high level of humidity is present within the room for a longer period of time due to generally high humidity in the ambient air (summertime) or a build up of high humidity over several hours (steam rooms/sauna etc.)
Pull Cord or switched live activation increases the trickle flow rate to boost for the selected timer period.
From 6 l/s trickle to 8 l/s
From 8 l/s trickle to 13 l/s
From 13 l/s trickle to 20 l/s
Wrap and store around stowaway mechanism if not required
The delayed start function of the fan to its' boost function is only activated by a remote switch and not by the pull cord.
Installation in the ceiling.
To avoid the back flow of condensation into the fan in the ceiling installations it is good practice to fit a condensation trap (optional—Airflow Part 51978301) to the vertical outlet duct of the fan.
Where flexible ducting is used the diameter must be maintained and it is good ventilation practice that the ducting is extended to 90% of its possible length in order to maintain the best possible airflow. Ensure that flexible duct connections are not over tightened to the fan outlet spigot. To avoid reduced air flow rigid ducting should be used (see airflow.com). The fan and ducting should be installed in accordance with the requirements of the Domestic Ventilation Compliance Guide, part of the Building Regulations.
SAFETY FIRST: ALWAYS ISOLATE THE FAN UNIT FROM THE POWER SUPPLY BEFORE REMOVING THE COVERS. When installed according to these instructions the iCONstant is completely safe. The materials used do not constitute a hazard.
The external housing of the fan can be wiped with a damp cloth. Do not use household cleaners containing abrasives. Note: Always isolate the fan when cleaning. Never clean any parts of the fan assembly by immersing in water or using a dishwasher.
