B. WIRING.
WARNING: THE FAN AND ANCILLARY CONTROL EQUIPMENT
MUST BE ISOLATED FROM THE POWER SUPPLY DURING
INSTALLATION OR MAINTENANCE.
IMPORTANT
The cross - sectional area of supply cord used should be ranged from 1 -1.5mm2.
The extraction fan or transformer (SELV models) is suitable for connection to
220-240V 50Hz supply.
The Transformer (SELV models 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 ll double insulated product and MUST NOT be earthed.
1. Select and follow the appropriate wiring diagram. (Fig. 1, 2, 3, OR 4, 5, 6)
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.
C. SETUP
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.
Once the fan has been commissioned please write the
installation date in the box on the label provided.
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.
Commissioning menu structure
* 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.
** Display: unl
Description: menu lock on or off. When locked a code is required to access the menu
Options: unl –unlocked Loc –Locked.

Description: Set the menu lock code. This is a 3 digit hexadecimal code, set between 0 - F.
Options: press up or down to start choosing the first digit then press mode to set and move to the next
digit. Repeat to set the other two digits. Default override code is 999.
The table shows the settings available to commission the fan. They appear in this order. 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 above, 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.
Lock feature (Revive 5,Revive 7 & Revive Intermittent models)
The lock feature will prevent the unit from being adjusted after commissioning as a pass code is
required to access the menu. This can be set in the menu to any 3 digit hexadecimal
combination.
If the lock feature is enabled; when a button is pressed the display will show, –––. At this point
enter the three digit code by first pressing + or –until the first digit is correct then press MODE
to move to the next digit. Repeat until the code is entered and press MODE to enter the
commissioning menu. If the code is entered incorrectly, wait until the screen switches off then
press any button to begin again.

D. SERVICING AND MAINTENANCE.
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.
E. TROUBLESHOOTING
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. (Section C)
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. (Section C)
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.
