18 Cleaning - Maintenance SL4 R
Before opening the door of the heat recovery system or carrying out maintenance on the kitchen
hood: Switch off the heat, let the fans continue for three minutes to remove hot air, remove the
power from the unit and wait 2 minutes before opening the doors.
Fans: Item pos. 5 and 6/Chap. 9 General Drawing, SL4 R. The fans must be cleaned once pr. year. The
fans are cleaned with a small brush and compressed air, if available. Remove the fans as follows:
(Fan item no. 6) Remove the cover in front of the fan by pressing the snap locks at the bottom
of the cover. For both fans: pull the fan out of the track and disconnect the contact. The motor
and fan blades are removed by unscrewing the 4 screws in the round motor plate and carefully
pulling the motor out of the motor housing. Mounting takes place in the reverse order.
Filters: To preserve a healthy indoor environment, it is important to change filters when they are
clogged/dirty. Clogged filters lead to:
Increased air resistance in the filter – less air in the home – the risk of bacterial growth in
the filter – in the worst case scenario, the system can be damaged.
How often the filters need to be changed depends on the degree of contamination of the air
where they are installed. In general, the filters need to be changed once a year, preferably in
the autumn (after the pollen season). In areas with a lot of dust and contamination, the filters
should be changed in the spring and autumn.
The supply air filter, which cleans the outdoor air (item no. 2) is a compact filter (filter class F7).
The filter is pushed in place in the fixing rails. The extract air filter (item no. 1) is a compact filter
(filter class F7) and is located in its own drawer which can be pulled right out after the finger
screws have been removed. We recommended that you order a filter subscription for full benefit
from the system and the cheapest prices.
Order no. for a complete set of filters: 12336
When changing filter, please perform an overall check of the ventilation unit.
Rotor: As the system has filters installed with a high tightness class, it is not normally necessary to
clean the rotor. If, for various reasons, it should still be necessary, dust can be removed with
a soft brush. Further cleaning is possible if you remove the rotor, spray it with fat-soluble
detergent and then blow it clean from the opposite side. Distance approximately 60mm and max.
pressure 80 bar. Ensure that the motor is not exposed to water during cleaning. Ensure that all
seals around the rotor are intact and tight.
Do not use detergent that is harmful to aluminium or the environment.
Valves and
duct system: Clean the valves at least once a year. The duct system must be cleaned at least every 10 years.
Outdoor air
intake: Check once a year that the grille is not clogged.
Roof hat: Check once a year that the drainage gap at the bottom is not clogged with leaves. This applies
only if the system has a roof hat.
