· Cleaning and user maintenance shall not be made by children
· The installer is responsible for the installation and electrical connection of the unit on site. It is the responsibility of the installer to ensure that the equipment is safely and securely installed and left only when mechanically and electrically safe.
· All regulations and requirements must be strictly followed to prevent hazards to life and property, both during and after installation, and during any subsequent servicing and maintenance.
· Certain applications may require the installation of sound attenuation to achieve the sound levels required.
· The unit must not be connected directly to a tumble drier.
· The exhaust grille should be located at least 600mm away from any flue outlet.
· This product and associated duct installation should be carried out in accordance with the Domestic Ventilation Compliance Guide.

INSTALLATION Position the unit, taking into consideration the position of the rooms to be ventilated, the exhaust position and the electrical services. Ensure there is adequate access for installation and maintenance. If the unit is sited in the heated void of the dwelling a condensate drain should not be necessary. When sited in a cold loft, consideration should be given to fitment of a condensate drain. Alternatively, the unit and ducting can be externally insulated to minimize condensation within the units housing. To reduce the system resistance in your duct system, and therefore lower the speed, power consumption and noise of the fan, follow these guidelines:
1.1. Keep the length of duct runs to a minimum, particularly the exhaust duct run. 1.2. If you need to use flexible ducting, make sure that it is fully extended and not crushed,
sagging or torn. 1.3. Try to minimize the use of diffusers/valves by having similar length duct runs to the inlets. 1.4. The bend radius (measured to the inside of the bend) should be at least 1x the duct diameter. 1.5. Avoid having any bends, filters or other obstructions within 250mm of the fan inlets and outlet. Securely mount the unit through the mounting holes on the casing using appropriate fixings (not supplied) for the mounting substrate. Fixings to be capable of securing 4x the weight of the unit. Unit weight: 4.1kg. Anti-vibration mounts, acoustic mats or rubber bushes can also be used. Mounting point dimensions and installation example shown below:
To maintain the IPx2 rating of the unit, the unit must not be mounted with the cover removal slots facing upwards, or at an angle where they are visible from above. All other orientations are acceptable.

WIRING
WARNING: THE UNIT AND ANCILLARY CONTROL EQUIPMENT MUST BE ISOLATED FROM THE POWER SUPPLY DURING THE INSTALLATION / OR MAINTENANCE. THIS UNIT MUST BE EARTHED.
1. To remove the cover, use a coin or similar; depress the retaining tabs via the slots in the side of the unit.
2. With the power off, connect a suitable mains power cable from a switched, fused spur to the screw terminal block. Use the cable clamps and clip provided to secure the lead.
3. Two mains voltage Live Switched (LS1 and LS2) connections are provided and can be used to trigger a change in speed. Common inputs would be from a bathroom lighting circuit. When commissioning the unit, a delay on timer and an overrun timer can be selected and adjusted in the software using the buttons and screen. See Commissioning section on page 5 of this document for details.
4. The switched live output (230Vac) from any other switch or controller, (such as a simple latching pullcord or push-button switch, humidistat or PIR detector) can be connected to the LS terminal instead of connecting to a lighting circuit.
5. Important: Use 4-core, low voltage, twisted pair, telecoms type cable for accessories (Vent-Axia part number 459931). Accessories are connected via the IO (Input Output) PCB; see the Low Voltage Connections diagram in the Main fitting and wiring guide, downloadable on the website.
6. There are no delay-on or overrun timers with the volt-free connection as the controller should determine when the fan is running at Boost or Normal speeds. Use the LS connection described above if you want a timer.

7. Units showing on the rating label incorporate an earth connection for functional purposes only. Units showing on the rating label have a Protective Earth.

COMMISSIONING
1. Commissioning and configuration on all products is supported by the 3-digit user interface and associated push buttons:
2. When powered on, the unit will display the firmware revision number, after a few seconds the unit will display the first option in the User Parameters (see table on next page).
3. The display will enter standby mode after defined timeout (default 10min) or user selects "END" option in menu, press the Mode button to turn the display back on.
4. Changes to the settings can be made via the + and ­ buttons, the Mode button will
accept changes and move onto the next menu option.
5. When setting the speeds, there is an internal logic: low<Normal<Boost<Purge. I.e., Boost is always higher than Normal.
6. The actions for each of the Live Switched (LS), inputs are selectable. The setting for delays and over run timers are applicable to all inputs.
7. If the unit being commissioned is not fitted with the relevant hardware, the associated menu options will not be available.
Pairing wired and wireless accessories (If supported by model)
To enter pairing mode, with the display illuminated, press and hold the Mode button until LED illuminates solid White, release the Mode button and the LED will flash White, indicating pairing mode is active along with the paired device count on the display. Pairing mode will time out after 5 minutes. To activate pairing on the accessory, refer to the device manual.
Control via Bluetooth
Selected units can be controlled via the Bluetooth linked App. With the display on, press and hold the Mode button until the Blue LED illuminates, release the button and the LED will flash signifying that pairing mode is enabled.
Use the QR codes on the coversheet to download the App.
SERVICING & 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 significant buildup of dirt or other deposits.
2. To inspect the inside of the product, isolate the power, use a coin or similar to depress the cover retention clips.
3. Remove the cover, remove the scroll assembly by unscrewing the two screws and unclipping the clips in the two corners and pulling away. If necessary, vacuum the inside of the unit.
4. The fan has sealed for life bearings, which do not require lubrication. Expected service life is at least 45,000 hours continuous running.
5. Check all fixings are tight and secure
