Information on Maintenance and Operation

For the Householder

Your home has been fitted with a mechanical ventilation system. The system should consist of a central mechanical extract fan, ducting, an external exhaust and extract valves in all the wet rooms e.g. the kitchen, bathroom and toilet. The proper working of the system will provide a healthy indoor atmosphere and will help eliminate condensation.

The Xplus 340 / Xplus 340DC system is (or can be) fitted with a 3-position switch, while the Xplus 340DCRF system is used in conjunction with a three speed wireless transmitter to set 3 different running speeds. The high speed setting is a boost position for the extract of cooking smells or moisture-laden air, when this is in use it is advisable to open window vents or a window to provide replacement air.

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 a boost.

The fan is designed to run continuously 24 hours a day. It is fitted with an energy efficient electric motor.


In normal running the design of the fan attracts very little dirt. It may be advisable to have the unit inspected by your installer once every 4 or 5 years and cleaned if necessary.

The electric motor and fan are enclosed in the ventilator housing. Attached to the casing are 4, 125 mm diameter spigots for ductwork connections, 3 for extract ductwork and one common spigot to take the waste air to atmosphere.


The installation should minimise resistance and prevent any leakage in the ducting. Where possible the use of flexible ducting should be avoided. If an extract spigot is not used it should be closed with a cover. If installing in a position where condensation is likely to run back towards the fan, you will need a suitable condensation trap.

Position of air intake:

As far as possible from and opposite to the main source of air replacement to ensure airflow across the room (e.g. Opposite an internal doorway).

Near the source of steam or odours.

Not where ambient temperatures are likely to exceed 50ºC, or above a cooker hob or eye level grille.

If installing in a room containing a fuel burning device, it is the installer’s responsibility to ensure that there is enough replacement air to prevent fumes being drawn down the flue when the fan is operating up to maximum extract. Refer to Building Regulations for specific requirements.

Exhaust air must not be discharged into a flue used for exhausting fumes from appliances supplied with energy other than electric. Requirements of all authorities concerned must be observed for exhaust air discharge.

The inlet grilles should be situated at least 0.5m distance from the discharge outlet of a flued

heating or cooking appliance. Position of the air outlet:

At least 0.5m away from open door or window, or the inlet of another ventilation device. The fan unit must always be firmly fixed.

This can be done by either of the methods below:

Using woodscrews fixed through the corner of the ventilator box.

Using threaded bolts in the notched holes.


The Xplus 340 and Xplus 340DC can be wired to run at speed 1, 2 or 3 or by use of a 3-speed switch, which gives speed choices to the user. The Xplus 340DCRF is to be wired to run at 3 speeds by use of the RF wireless control system. See section on remote control. For wiring of the ventilation unit see wiring instructions.


This fan unit requires little maintenance.

Every 4-5 years it is advised to disassemble the unit, remove the motor and impeller assembly and clean the impeller using soapy water (making sure that water does not get into the motor)


This unit meets all relevant CE standards.

Removing the cover

Insert a screwdriver in one of the 4 openings in the slanting corners of the box.

Turn the screwdriver so that the corner piece unlocks and loosens the cover.

It may be necessary to unlock more than one corner.

Removing the motor and impeller assembly

Remove the motor and impeller assembly by using the 3 click connections fixed to the casing. Insert a screwdriver into one of the grooves and turn it until the section becomes free.

When all 3 positions are loosened the motor plate can be removed from the casing. Reassembly

Place the ventilator unit in the correct position and click the cover back in place.
