Filter change, maintenance
Check the unit filters and any built-in external and room filters every 3 months and replace them if necessary.
Have your ventilation unit cleaned and maintained every 2 years. This is the only way of ensuring that the ventilation unit is running in accordance with the prescribed health and hygiene requirements.
If you have a maintenance contract, your specialist installer will ensure regular unit cleaning/maintenance. For more information → installation, commissioning and maintenance instructions.
