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.
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 Vallox ventilation unit door by first lifting the latch
fully up and then lowering it back a little way.
3. Lift the door off.
CAUTION
The door is heavy.
4. Remove the filters (A, B, C).
5. Remove the sealing strip (E) above the cell in the direction of
the arrow.
6. 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.
7. 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.
8. Rinse the cell clean with a 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. When reassembling Vallox 096 MV, check that the sealing
strip below the cell is pressed against the bottom of the unit.
11. Close the door. Ensure that the safety switch catch of the
door is touching the safety switch.
12. Plug the ventilation unit back into the mains.
The heat recovery cell has now been checked and cleaned.
MAINTENANCE
CONDENSING WATER
In the heating season, the extract air humidity condenses to
water. In new buildings, condensation runoff can form rapidly.
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.
