The fan unit should not be used: ● in single air extraction systems according to DIN 18017-3. ● close to flammable materials, liquids or gases. ● to convey chemicals, aggressive gases or vapours. ● in potentially explosive atmospheres. ● outdoors ● if there is no protection against accidental contact with the impeller on the discharge side in accordance with EN ISO 13857.

3. Environmental conditions and

operating limits ● Permissible maximum temperature of air medium + 40 °C. ● The domestic air supply must be set up so that virtually no air can flow into the living areas from the kitchen, bathroom and WC. ● A room from which the air has to be ex- tracted must be fitted with a non-closable, free supply air cross section of at least 150 cm²,e.g. with Maico door ventilation grille MLK. ● Sufficient supply air intake must be en- sured during operation with air-ventilated fireplaces. The maximum permitted pressure difference per living unit is 4 Pa. ● VZ, F, KVZ and KF units: Resistance to interference according to EN 55014-2 depending on pulse shape and energy component 1000 to 4000 V. If operating with fluorescent tubes, extra interference suppression measures are needed (L or C components or RC modules, protection diodes, varistors) because these values may be exceeded.

● Read these operating instruc- tions carefully before moun- ting and commissioning. ● Assembly and electrical con- nection may only be under- taken by trained specialists in accordance with Chapter 1. ● With electrical and equipment installation the relevant regulations must be observed, in Germany particularly DIN VDE 0100 with the correspon- ding parts. ● Only connect unit to perma- nently wired electrical instal- lations with NYM-O or NYM-J (2 x 1.5 mm² or 3 x 1.5 mm²) cables. Mains isolation device required with contact openings of at least 3 mm at each pole. ● The fan unit may only be operated using the voltage and frequency shown on the rating plate. ● Only operate the fan unit when it is completely installed.UK │ 5.
