Maintenance
This chapter describes the maintenance of a Vallox ventilation unit.
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.
Warning:
If water is used to clean any part of the ventilation unit, ensure that it is kept out of the electrical system.
Note:
There are two unit models, left- (L) and right-handed (R). The figures in the following sections show the right-handed model.
In the right-handed version, outdoor air comes into the unit from the right side of the centre line as shown in the instructions. In the left-handed version, outdoor air comes into the unit from the left. Also the position of the filters, HR cell bypass damper, and heating resistor is mirrored in the left-handed model.
The following table shows the recommended maintenance intervals for the Vallox ventilation unit.
