HEAT RECOVERY CELL
Check that the heat recovery cell (D) is clean roughly
once a year when the filters are being replaced. Clean by
washing as required.
•
Pull the coarse filters including the frames out of the
unit (A and C). Also remove the fine filter, if any (C).
•
Remove the sealing strip (E) above the heat recovery
cell in the direction of the arrow.
•
Once you have removed the sealing strip, pull the
heat recovery cell out of the unit.
IMPORTANT! Handle the cell carefully! For example, do
not lift the cells by the layers. The cell layers are very thin
and easily damaged.
If the heat recovery cell is dirty, clean it by immersing it in
water containing a small amount of a mild detergent. Rinse
the heat recovery cell clean with a water spray. When all
the water has drained from between the layers, push the
cell recovery cell back in place. Lastly, push the sealing
strip back in place.
CONDENSING WATER
In the heating season, the extract air humidity condenses
to water. In new buildings, condensation runoff can form
rapidly. Condensed water must be able to freely leave the
unit. At some time before the heating season begins (e.g.
during autumn maintenance), check that the condensing
water outlets in the bottom pool are not clogged. To check
this, pour some water into the pool. Clean as required.
Water must at all times be kept out of the electrical system.
See the condensing water connections on page 15.
