Description of Components

Fans

• The fans have external rotor motors of EC type which can be steplessly controlled individually between 10-100%. The motor bearings are life time lubricated and maintenance-free. It is possible to easily disconnect and replace the fans if necessary.

Filters

• The filters are of filter quality G4 for both the supply air and extract air filter.
• The filters need to be cleaned regularly (and replaced when polluted) during maintenance. New sets of filters can be acquired from your installer or wholesaler.

Heat exchanger

• The unit is equipped with a highly efficient, counter-flow plate heat exchanger. Supply air temperature is therefore normally maintained without adding additional heat. The heat exchanger is removable for cleaning and maintenance during service.

Condensation drainage

• Depending on the relative humidity in the extract air, condensation may occur on the cold surfaces of the heat exchanger, on one side in winter time, on the other side in summer time (Table 6.b).
• The condensate water is led out through drainage pipe.

Thermistor

• Temperature probe to implement temperature dependent functions.

Maintenance

WARNING: Make sure that the mains supply to the unit is disconnected before performing any installation, service, maintenance or electrical work!

• Keep the unit surface free from dust.
• Once every 3 months (fixed period), the unit warns the user to perform the filter maintenance (red light). The actual need to perform this operation may vary depending on indoor and outdoor ambient conditions.
• Clean the filters with a vacuum cleaner (Fig. 8.b-c-d-e).
• Press the dedicated button for at least 3 seconds to reset the timing (Fig. 8.f).
• Replace the filters every year.
