On the outdoor air side, the filter efficiency of ISO ePM1 50% (F7 according to EN 779) or better is
recommended. For the extract air side, a filter efficiency of at least ISO Coarse 60% (G4 according to
EN 779) is recommended. If not in standard configuration, the recommended filter is available as an
accessory part.
Frost protection
Appropriate measures should be taken to prevent the heat exchanger and optional downstream
hydraulic heater coil from getting damaged by frost during extreme winter temperatures (−15 °C). It
must be ensured that the unit’s ventilation performance is not affected during frost protection cycles.
Frost protection of the heat exchanger:
In order to protect the heat exchanger from freezing, for cool-temperate climate, the unit is
equipped as standard with an electrical preheater. The frost protection strategy is appropriate
to protect the heat exchanger from frost down to an outdoor air temperature of -15 °C (verified
by measurement results). The unit can also be equipped with a hydraulic heater.
Frost protection of downstream hydraulic heater coils:
This unit provides a frost protection of the downstream hydraulic heater coils. In the case
the hydraulic post-heating coil is used, the unit is automatically switched off when the supply
air temperatures drops below 5 °C.
