Cleaning the heat recovery cell (User)
Warning
The safety switch automatically turns off the power when the upper door of the Vallox ventilation unit is opened. Always disconnect the Vallox ventilation unit from the mains before starting maintenance.
Check that the heat recovery cell is clean roughly once a year, or whenever the filters are being replaced. 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:
-
Disconnect the ventilation unit from the mains electricity supply.
-
Lift the latch to open the door of the ventilation unit.
-
Lift the door off.
Caution
The door is heavy.
-
Remove the filters (A, B, C).
-
Remove the sealing strip (E) above the cell in the direction of the arrow.
-
Lift and pull the cell (D) out of the unit.
Important
Handle the cell carefully! For example, do not lift the cell by the layers. The cell layers are very thin and easily damaged.
-
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.
-
Rinse the cell clean with a water spray. Do not use a high-pressure cleaner.
-
When all the water has drained from between the layers, reassemble the ventilation unit in the reverse order.
-
Close the door and plug the unit back into the mains.
The heat recovery cell has now been checked and cleaned.
