Maintenance

This section describes the maintenance of the 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:
Always disconnect the power plug before starting maintenance on the ventilation unit. The unit has no safety switch that would switch the power off when the door of the unit is opened.
Warning:

If you are using water to clean unit parts, be careful that the water does not touch the electrical parts.

Important:

If the power cord is damaged, the manufacturer, their service representative or another equally qualified person should replace it to avoid accidents.

Note:

Vallox ventilation units are available in two models: a left-handed (L) and a right-handed (R) model. The images below depict the right-handed model.

In the right-handed model, outdoor air enters the unit from the right side of the centre line, as shown in these instructions. In the left-handed model, outdoor air enters the unit from the left. Correspondingly, the placement of the filters, HR cell bypass damper and heating resistor is reversed.

The table below indicates the recommended maintenance intervals for different Vallox ventilation unit parts.
