Air / air heat exchanger

With correct maintenance, the heat exchanger can achieve efficiencies of over 90% under appropriate working conditions. This can lead to the accumulation of condensate, which is collected in the condensate tank and must be drained off via a condensate drain. At low outside temperatures, the condensate in the heat exchanger can freeze.

To prevent the heat exchanger from freezing, the control is equipped with an anti-frost function as standard (reduction of the supply air volumetric flow). Alternatively, an electric preheating register can be connected upstream for balanced operation.

Protect the heat exchanger by regularly cleaning or replacing the filters!

If the unit is used with regularly changed filters, contamination of the heat exchanger is virtually impossible. If cleaning is nevertheless required, the heat exchanger can be flushed with compressed air.

• Before commissioning, check that the condensate drain has been properly installed.
• If there is a risk of frost on the condensate drain, a frost protection heater must be installed (not included in the scope of delivery).
