INSTALLATION
DESCRIPTION

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED
FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE.
IMPORTANT
The cross-sectional area of supply cord used should be ranged from 1 -1.5mm
2
.
The extraction fan or transformer (SELV model) is suitable for connection to
220-240V 50Hz supply.
The Transformer (SELV model only) MUST be surface mounted to allow air to freely
circulate around the unit. When installed in a loft void it MUST NOT be enclosed or covered
with insulation.
The fan is a class II double insulated product and MUST NOT be earthed.
1. Follow the wiring diagram shown.
2. Check all connections have been made correctly and ensure all terminal connections
and supply wires are securely fastened.
3. Ensure the impeller rotates and is free from obstructions.
Accessing the commissioning menu
To configure the fan first remove the grille. With the grille removed the control board is visible
(Fig.7). Do NOT isolate the fan from the power supply as configuration requires power to the
fan; removing the grille will automatically stop the impeller from spinning.
IMPORTANT
Do NOT attempt to remove the circuit board cover (Fig.7). This covers
the high voltage power supply, preventing the risk of an electric shock.
With the cover removed the LED display will show the commissioning menu. There are 3
buttons located below the display; these are used to control the setup process:
The + button is used to increase the value of a setting, the – button is used to reduce the
value of a setting and the X(Mode) button moves to the next setting.

* This setting rotates the display only; the buttons retain their original function. For example; the
mode button is on the right when in normal rotation and on the left when the screen is rotated and
looking at the fan so the display is correctly orientated.
The table shows the settings available to commission the fan. They appear in this order
starting with the bathroom or kitchen mode selection. The available options and default
position for each setting is also shown.
Settings
Installation selection
There are four different installation type settings, kitchen or bathroom and ducted or
window/wall. The difference between bathroom and kitchen mode is shown below, the boost
speeds are higher for kitchen applications. If the fan is installed in a ducted setup changing
the fan to ducted mode will compensate for the reduced airflow due to the higher pressure of
the system. During commissioning select the relevant setting for your installation.
Boost time
The boost setting allows the boost timer to be adjusted from 1-30 minutes, the default is 15
minutes.
Humidity level trigger
The humidity setting defines at what relative humidity the fan will trigger, adjustable from 50%
to 70% rH.
Comfort mode
Comfort mode changes how the fan boosts. Normally the fan will go into boost as soon as an
LS input is detected and over run for the set period when LS is disconnected. In comfort
mode the fan will not boost until the LS has been on for 5 minutes, preventing nuisance
noise. After 5 minutes of LS being on the fan will run in boost as long as LS is on and for the
over run time after LS is switched off. If the LS is switched off before 5 minutes the fan will not
boost. This mode does not affect the pullcord operation, pulling the pullcord will still activate
boost.

Pull Cord Function
Pull Boost 1 Pull Boost 2 Pull Boost Off
Pulling the pullcord will activate boost 1, a second pull will enter boost 2 and a third pull will
cancel the boost, returning the fan to trickle speed. The pullcord can be used to cancel an LS
activated boost, if the fan is in an LS activated boost pulling the pullcord will first enter boost a
further pull will return the fan to trickle.
Data Logger (ACR60 model)
With the fan powered up; upon removing the cover the display will automatically activate. It
will display the commissioning options. Holding down the Mode button for 5 seconds will open
the data logger menu. Use the mode button to move the display to the next data set.

WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING MAINTENANCE.
1. At intervals appropriate to the installation, the fan should be inspected and cleaned to
ensure there is no build-up of dirt or other deposits.
2. Wipe the inlets and front face with a damp cloth until clean.
The fan has sealed for life bearings, which do not require lubrication.
1. The fan continuously runs in boost:
a. Cause:
i. The room is damp or recently redecorated.
ii. The humidity set point is set too low.
b. Solution:
i. If the room is damp or has recently been decorated, it could take up to 2
weeks for the humidity levels to stabilise. Please leave the fan to dry out
the room and after this period the fan should run normally.
ii. The humidity set point could be set too low. Adjust the humidity set point to
a higher setting. (Setup Section)
2. The fan does not boost when the humidity is high:
a. Cause:
i. The humidity set point is set too high.
b. Solution:
i. Adjust the humidity set point to a lower setting. (Setup Section)
SERVICING AND MAINTENANCE
TROUBLESHOOTING

3. Water is dripping out of the fan when installed in a ceiling:
a. Cause:
i. This is caused by condensation forming on the inside of the ducting and
dripping out of the fan inlet.
b. Solution:
i. This is normal and the fan is designed to handle condensation build up.
However a condensation trap connected immediately after the fan will help
to prevent water dripping into the room.
