MAINTENANCE
CLEANING THE HEAT RECOVERY CELL
(USER)
Check that the heat recovery cell (D) is clean roughly once a
year when the filters are being replaced. Clean by washing as
required.
IMPORTANT
Handle the cell carefully! For example, do not lift the cell by the
layers. The cell layers are very thin and easily damaged.
To check the heat recovery cell (HR cell):
1. Disconnect the ventilation unit from the mains electricity
supply.
2. Lift the latch to open the door of the ventilation unit.
3. Lift the door off.
4. Pull the G4 filters (A, C) and filter supports out of the unit.
5. Remove the sealing strip (E) above the HR cell.
6. Remove the side sealing strip (F).
7. Remove the G7 filter (B).
8. Lift and pull the cell (D) out of the unit.
9. 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.
10. Rinse the cell clean with a water spray. Do not use a high-
pressure cleaner.
11. When all the water has drained from between the layers,
reassemble the ventilation unit in the reverse order.
12. Close the door. Ensure that the safety switch catch of the
door is touching the safety switch.
13. Plug the ventilation unit back into the mains.
14. The heat recovery cell has now been checked and cleaned.
IMPORTANT
If the unit has an enthalpy cell, it must not be washed. Only
aluminium or plastic cells can be washed.
