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.
To check and clean the heat recovery cell:

1.  Disconnect the ventilation unit from the mains electricity 

supply.

2.  Open the door of the Vallox ventilation unit by undoing the 

finger screws.

3.  Lift the door off. 

CAUTION

The door is heavy.

4.  Remove the supply air filter (A).

5.  Turn the upper support of the HR cell (B) to the upper 

position (anti-clockwise).

6.  Remove the extract air filter (C).

7.  Lift and pull the HR cell (D) out of the unit.

8.  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.

9.  Rinse the cell clean with a water spray. Do not use a high-

pressure cleaner.

10.  When all the water has drained from between the layers, 

reassemble the ventilation unit as follows:

11.  Ensure that the lower support (E) is in place against the 

knobs at the bottom of the unit.

12.  Lift the HR cell in place.

13.  Turn the upper support against the cell. Ensure that the 

upper support is properly nestled against the cell (remains 

upright). 

14.  Install the extract air filter (C) and the supply air filters (A) in 

place.

15.  Close the door. Ensure that the safety switch catch of the 

door is touching the safety switch.

16.  Plug the ventilation unit back into the mains. 

 

The heat recovery cell has now been checked and 

cleaned.

MAINTENANCE

IMPORTANT

Handle the cell 

carefully! For example, 

do not lift the cell by the 

layers. The cell layers 

are very thin and easily 

damaged.

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.
