3.4.4 Cleaning air valves
Clean the valves twice a year.
• Remove a valve from the wall or ceiling.
• Clean the valve in soapy warm water, Rinse well and dry. The installer will have set all the valves to
ensure the optimum functioning of the system. Do not therefore adjust the position of the valves.
• Place the valve back in its correct location.
• Repeat this procedure for all the valves.
Ventilation air is supplied and extracted via the valves. Gaps under doors in the dwelling ensure that
the air flows in the right direction.
• Do not obstruct these gaps.
• To maintain the correct amount of ventilation in the correct rooms, the valve setting must not be
altered. Also make sure that the valves do not get swapped.
3.5 Malfunctions
3.5.1 Malfunction alarm
If the Xcell 350V EC BP malfunctions, this will be indicated in the following manner:
3.5.2 Display
The display will show an ‘A’ or an ‘E’ code with a number
3.5.3 What to do in the event of a malfunction
In the event of a malfunction, contact the installer. Note the code shown in the display and the Product
number. This is given on the rating plate on the top of the unit.
The unit should not be electrically isolated unless it has to be deactivated due to a serious malfunction,
or for filter cleaning/replacement or any other urgent reason. When the unit is isolated, the dwelling will
no longer enjoy mechanical ventilation, and this can lead to problems with damp and mould. Protracted
deactivation of the unit must therefore be prevented.
