4. Maintenance and Repairs
Before you start any kind of maintenance, switch Ventoxx RV units off
and disconnect them from the power supply. The ceramic heat
exchanger is fragile, do handle it carefully and do not let it fall.
4.1.
Maintenance of the Unit
4.1.1. Filter
The filter is suitable for long-term use. Cleaning is carried out under running water. If damaged,
the filter must be replaced.
Filter requires changing or cleaning every three months. A flashing red LED on the control
indicates that.
4.1.2. Fan
The condition of the fan should be checked annually. Even if the filter is cleaned regularly, a
small amount of dust can stick to the fan. This may lead to lower efficiency. The fan can be
cleaned with airflow or with a soft sponge or brush.
4.1.3. Heat Exchanger
We recommend annual check of heat exchange unit. If there is contamination of the heat
exchanger, proceed as follows:
Turn the power off
Remove the inner cover and the filter
Disconnect the electrical terminal
Get the ventilator unit removed from the piping
Carefully remove the fan from the ventilator unit
Now the heat exchanger can be cleaned with a vacuum cleaner or a damp cloth.
We recommend you to avoid cleaning the unit in the dishwasher not to damage
the insulation!
4.1.4. Control
The control itself does not require any special cleaning. Should there be any cleaning of
Ventoxx RV unit or its filter change, yet the fans must be turned off via the control (see
operating modes).
