Installing the Diffuser
Prepare a hole in the ceiling.
Using the mounting ring as a template, drill 4 holes and fix using the screws provided.
Finally, screw the valve body into the ceiling mounted ring.
Location of the Ventilation Unit
Locating the ventilation unit in a well-ventilated loft space is recommended to ensure sufficient fresh air is available. The unit should
be installed in a position where the air inlet cannot be obstructed.
Ducting should be considered when choosing the location for the ventilation unit. The installation should aim to minimise air
resistance and prevent any leakage in the ducting. Where possible the use of flexible ducting should be minimised. Flexible duct
should not be compressed.
NOTE:
Care should be taken to ensure ducting is as straight and uncompressed as possible with minimal bends. This will
reduce resistance in the air flow path allowing greater performance at lower speed settings thus improving energy
efficiency and reducing noise.
NOTE:
Use of solid duct exclusively may result in increased noise as a result of vibration. A short length of flexible duct
should be used to transition from solid duct to the diffuser.
WARNING: DO NOT install this product in areas where the following may
be present or occur:
•Corrosive or flammable gases, liquids or vapours.
•Ambient temperatures are higher than 50 °C or less than -5 °C
•Possible obstructions which hinder access to or removal of the Fan.
Orientation of the Unit

Installation of Smoke Detector or CO Detector (optional)
To enable the safe cut-out of the ventilation system in case of fire, the ventilation unit can be connected to an optional smoke
detector or CO detector with a volt free output. The smoke or CO detector must be normally closed (NC) and will go open circuit
(OC) in the event of a fire. When the ventilation unit detects an open circuit, the fan will stop to prevent feeding fresh air to a fire
and will not restart until it is powered down and restarted.
NOTE:
If an external smoke detector is not used then a link wire MUST be fitted across the “Smoke Detector” terminals on
the Main Connector PCB. These link wires are fitted to all units leaving the factory.

User Information
Your home has been fitted with a highly energy efficient mechanical ventilation system. The system should consist of an Everdri
XEL central mechanical supply fan, ducting and discharge diffuser. The correct working system will provide a healthy indoor
atmosphere and will help eliminate condensation and unwanted odours by supplying filtered fresh air into your home.
The fan is designed to run continuously 24 hours a day. It is fitted with an energy efficient electronic motor.
Manual Override Switch Control Options
The Everdri XEL system is supplied with a Manual over-ride switch, allowing you to switch between a low trickle speed (in
Automatic mode) and 2 additional speeds in Manual mode. The high-speed setting is a boost position to allow for the extract of
cooking smells or moisture-laden air. When in use, it is advisable to open window vents or a window to allow the moisture laden air
to escape. The middle position would be the normal running position in a house with the low speed position as a background
position if the house is not fully occupied. In a smaller dwelling or flat the low speed position could be the normal running position
with the middle position as boost.
