CLEANING THE HEAT RECOVERY
CELL
Check that the heat recovery cell is clean roughly once a year,
or whenever the filters are being replaced. Clean by washing
as required.
Cleaning the heat recovery cell:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the door of the ventilation unit by undoing the
finger screws and by lifting the door off.
CAUTION
The door is heavy.
3. Pull out the black upper support of the cell (E) located
above the cell.
4. Lift and pull the cell (D) out of the unit.
IMPORTANT
Handle the cell carefully! Do not lift the cell by the
layers. The cell layers are very thin and easily damaged.
5. If the cell is dirty, clean it by immersing it in warm water,
to which a small amount of a mild detergent has been
added.
6. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
7. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
8. Close the door.
9. Plug the ventilation unit back into the mains. The heat
recovery cell has now been cleaned.
MAINTENANCE
CONDENSING WATER
In the heating season, the extract air humidity condenses to
water. In new buildings, the volume of condensing water can be
high. 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 siphon or the condensing
water outlet in the bottom pool are not clogged. To check this,
pour some water into the pool. Clean as required.
NOTE
Some condensing water
may have accumulated
in the bottom pool
of the unit; this is
normal and requires no
corrective action.
WARNING
Water must at all times
be kept out of the
electrical system.
