If the appliance remains out of use for extended periods,
we advise removing the filters to prevent any possible
damage from the build-up of condensation.
Heat exchanger
Heat exchangers do not usually need frequent cleaning.
Any need for cleaning can be determined by a high
degree of air pollution (both entering and leaving the
house) and by the filters being in poor condition.
The heat exchanger should however be replaced every
six years even if the filters have been regularly serviced.
To access the heat exchanger, follow the instructions
below:
• disconnect the appliance from the mains;
• remove the heat exchanger (figs. 34,35,36);
