Installation
Optimum initial adjustment of plant
Air measuring equipment is used.
Before starting initial adjustment, check that the 5 points
in the inspection and initial adjustment section have been
carried out. Then start up the unit:
Set the initial basic ventilation value, which is speed 2.
To reduce energy consumption as much as possible, first
adjust the main air volumes to the desired air volume by
changing the voltage outlet on the transformer.
Then adjust the supply and extract valves with air
measuring equipment (Remember when performing initial
adjustment of the valves to lock them and to turn the guide
plate in the supply valves so the air blows in the right
direction).
Then check the main air volumes again and fine-adjust the
main air volumes with the fresh air and escaping dampers
(Remember to lock the dampers after initial adjustment).
Maintenance of plant
Filters:
When the red lamp on the control panel flashes, the filters
must be changed/cleaned.
Stop the plant with the switch on the unit or the electrical
panel. Remove the front cover and take out the bag filter
and flat filter. The bag filter may be cleaned two or three
times with a vacuum cleaner before replacing it.
The flat filter can be taken out of its frame and washed in
warm soapy water. Then hold the filter diagonally so the
water runs out. The filter must not be wrung out or washed
in dishwasher. After two or three washes, replace the flat
filter. Replace the flat filter in its frame, set both filters in
the unit and refix the front cover. Then switch on the unit
and press the left-hand button on the control panel for 10
seconds until the red lamp goes out. If it is desired to clean
the filters at a different time interval, this can be adjusted
on the control circuit board filter timer potentiometer,
mounted in the electrical cabinet. Remember to turn off the
current before opening the electrical cabinet.
Condensate drain:
When changing the filter in August/September, before
outside temperatures fall to 5°C, check the condensate
drain for blockage by dirt and check that there is water in
the water trap.
Pour 1 litre water into the condensate tray and make sure
it can run off unhindered. If the condensate drain does not
work, this could lead to water damage in the dwelling.
