Fan Dimensions
The iCONstant range consists of timer and humidity/timer
variants. They are designed for use in any wet room. Trickle
ows rates of 6, 8 or 13 l/s can be activated on installation.
Boost ow 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.
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.
1. Locate back plate cover on to main body assembly.
2. Twist back plate cover clockwise until locked. (Arrow
should be in the 12 o’clock position).
3. Secure back plate cover with xing screw.
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.
Remove back plate cover.
1. Remove screw at base of back plate cover.
2. Twist back plate cover anticlockwise.
3. Lift away.
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.

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.
Remove electronics cover.
1. Undo the 2 xing screws,
2. Lift off electronics cover.

Fit electronics cover and secure with the 2 xing 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.
To adjust the airow rate on commissioning, press top button
to increase ow rate, press bottom button to decrease ow
rate.
Where exible 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 airow. Ensure that exible duct
connections are not over tightened to the fan outlet spigot.
To avoid reduced air ow rigid ducting should be used
(see airow.com). 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 back ow of condensation into the fan in the
ceiling installations it is good practice to t a condensation
trap (optional—Airow Part 51978301) to the vertical outlet
duct of the fan.
Installation in the ceiling.
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.
Cleaning
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.
Warranty

This warranty does not in any way affect any statutory or other
consumer rights.
Disposal
Do not dispose of with household waste.
Please recycle where facilities exist.
Check with your local authority for recycling advice.
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.)
Commissioning adjustment
Pull Cord or switched live
activation increases the
trickle ow 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
Pull cord storage
Wrap and store around
stowaway mechanism
if not required
Delayed start
The delayed start function of the fan to its’ boost function is
only activated by a remote switch and not by the pull cord.
