Checking the fans
Even if the required maintenance, such as change of filters, is carried out dust and grease may slowly build
up inside the fans. This will reduce the efficiency.
The fans are easily taken out from the unit
(fig 4
) and may be cleaned with a cloth or a soft brush with a
recommended interval of once per year. Do not use water. White spirit can be used to remove obstinate
settlements. Allow drying properly before remounting.

Cleaning extract louvers and inlet diffusers
The system supplies treated outdoor air to the building and extracts the used indoor air via the duct system
and diffusers/louvers. Diffusers and louvers are mounted in ceilings/walls in bedroom, living room, wet
rooms, WC etc. Remove diffusers and louvers and wash in hot soapy water if required. Diffusers/ louvers
must be put back with their original settings and positions in order not to unbalance the system.
The cleaning of these parts is done when necessary.
Checking the outdoor air intake
Leaves and pollution could plug up the air intake grille and reduce the unit’s capacity. Check the air intake
grille at least twice a year and clean if necessary.
Checking the duct system
Dust and grease settlements may build up in the duct system even if filters are changed regularly. This will
reduce the efficiency of the installation. The ducts 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/louver openings or special inspection hatches in the duct system (if fitted).
NB!
Possible roof cowls must be checked once a year and cleaned when necessary.
