3.4 Check and Clean a Heat Exchanger
Danger
• Make sure that the Mains supply to the unit is disconnected before performing any maintenance or
electrical work!
Warning
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
Even if the required maintenance is carried out, dust will build up in the exchanger block. It is therefore of vital impor-
tance for the upkeep of a high efficiency that the exchanger block is removed from the unit and cleaned periodically as
illustrated below. Clean the heat exchanger at least every 3 years or when required.
212961 | 01

10 |Maintenance
1 Disconnect the rotor power supply and the rotor sen-
sor. The cables are found beside the rotor at the back.
2 Pull out the rotor towards you. Some force may be
needed.
3 Clean the rotor.
Wash in hot soapy water. Do not use detergent con-
taining ammonia. Rinse using, for instance, a shower
handle.
Warning
Ensure the rotor motor is not exposed to
moisture
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.
212961 | 01

Trouble shooting | 11
3.6.4 Checking and cleaning the duct system
Dust and grease deposits may build up in the duct system, even if required maintenance such as changing of filters is
being carried out. This will reduce the efficiency of the installation.
The duct runs should therefore be cleaned/changed when necessary. Steel ducts can be cleaned by pulling a brush
soaked in hot soapy water through the duct via diffuser/louvre openings or special inspection hatches in the duct sys-
tem (if fitted).
It is recommended to do this every 5 years and is normally carried out by authorized companies specialized in this area.
