CLEANING THE HEAT RECOVERY
CELLS (USER)
Check that the heat recovery cells are clean roughly once a
year when the filters are being changed. Clean by washing
as required.
IMPORTANT
If the unit has an enthalpy cell, it must not be washed. Only
aluminium or plastic cells can be washed.
To check and clean the heat recovery cell:
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Open the doors of the unit.
3. Remove the filters (A, B, C).
4. Remove the support grid of the filters.
5. Disengage the upper support strip (D) of the cell.
6. Lift and pull the cell (E) out of the unit.
7. If the cells are dirty, clean them by immersing it in warm
water, to which a small amount of a mild detergent has
been added.
8. Rinse the cell clean with water spray. Do not use a high-
pressure cleaner.
9. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
10. Close the doors. Ensure that the safety switch catch of
the door is touching the safety switch.
11. Plug the ventilation unit back into the mains.
The heat recovery cells have now been checked and
cleaned.
IMPORTANT
Handle the cells carefully! For
example, do not lift the cells by
the layers. The cell layers are
very thin and easily damaged.
