3.5 Cleaning the fans

Danger

• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or

electrical work!

The motor bearings are life time lubricated and maintenance free.

Even if the required maintenance, such as changing of filters is carried out, dust and grease may slowly build up inside

the fans. This will reduce the efficiency.

1 Disconnect the fan power cables. The cables are found

beside the fan at the back.

2 Remove knob at the lower part of each fan.

3 Pull out the fans towards you. Some force may be

needed.

4 Clean the fans with a cloth or a soft brush. Do not use

water. White spirit can be used to remove obstinate

deposits.

Allow the fans to dry properly before remounting.

5 Remount the fans. Don’t forget to reconnect the fan

power cables.

3.6 Duct System Maintenance

3.6.1 Cleaning extract louvres and supply air diffusers

The system supplies fresh air to your home and extracts the used indoor air via the duct system and diffusers/louvres.

Diffusers and louvres are mounted in ceilings/walls in bedrooms, living room, wet rooms, WC etc. Remove diffusers

and louvres and wash in hot soapy water as required (diffusers/louvres must not be exchanged). Cleaning of diffusers/

louvres can be done as necessary.

3.6.2 Checking the outdoor air intake

Leaves and pollution could plug up the air intake grille and reduce the capacity. Check the air intake grille, and clean as

necessary. It is recommended to do this at least twice a year.

3.6.3 Checking the roof cowl (if fitted)

The roof cowl (if fitted) connected to the exhaust air duct needs to be checked at least twice a year and cleaned if

necessary.
