Product information

Humidity control function for H and KH units Once the fan is installed, it adjusts itself to the prevailing room humidity (relative humidity). This humidity value is saved as the first reference value. The reference value does not have to be specified manually. If the relative humidity falls below the reference value during operation, the newly established reference value is saved. The lowest possible reference value is 48 % relative humidity. If the room humidity increases by 7 %, the fan engages automatically at performance level 1 (78 m³/h). ● If the room humidity increases even further, the unit switches to performance level 2 (92 m³/h). ● If there are no further increases, the unit continues to run at performance level 1 until the humidity again falls below the saved reference value. If the humidity falls below the reference value, overrun mode starts with the set overrun time. The current reference value is then saved. If the humidity does not fall below the reference value within 60 minutes, the unit switches to the set overrun mode and then switches off. H and KH units can also be operated using the light switch. The set opera- ting program starts when the light is switched on ( chapter 7.3). The operating program takes priority over the automatic humidity process. If the light is switched off, the unit continues to run until the remaining overrun time has passed. The automatic humidity process is then assigned maximum priority again and controls the unit as described above.

● This fan is only intended for domestic use and similar purposes. ● Fan for or extracting air from bathrooms, toilet rooms, storage rooms, showrooms, offices, fitness studios, changing rooms and similar places. ● An operation is only permitted when: ● permanent installation in buildings. ● installation on walls or ceilings. ● air supply via shaft or pipe. ● recessed mounted electrical connection. ● Window installation permitted with window installation kit FE 100/1, connection in flat channel duct systems permitted with spacing frame ECA-DR.

2.4 Predictable misuses

Maico is not liable for damages caused by use contrary to the intended purpose. Under no circumstances the unit should be used: ● in single air extraction systems according to DIN 18017-3. ● close to flammable materials, liquids or gases. ● for the conveying of chemicals, aggressive gases or vapours. ● in potentially explosive atmospheres ● outdoors.

3. Environmental conditions and

operating limits ● Maximum permitted temperature of the air medium + 40 °C. ● Sufficient supply air intake must be ensured during operation with air- ventilated fireplaces. The maximum permitted pressure difference per living unit is 4 Pa. ● 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. ● Recommendation: Connect a X2-capacitor (220 nF/250 V) against neutral lead in case of a switch with negative-glow lamp. The capacitor is to be provided by the customer.

● Assembly and electrical connection may only be undertaken by electricians in accordance with chapter 1. ● Read these operating instruct- tions carefully before commis- sionning. ● Only connect unit to perma- nently wired electrical install- lations with NYM-O or NYM-J (3 x 1.5 mm² or 5 x 1.5 mm²) cables. Fixture for disconnect- ting from mains, with at least 3 mm contact opening needed per pole. ● The fan unit may only be operated using the voltage and frequency shown on the rating plate. ● Do not make any modifica- tions to the fan unit. ● Never operate unit without electronics cover [4] and cover [6].

5.2 Safe and correct practices

during operation Danger of injury caused by objects in the impeller. Do not insert any objects in the fan unit. Danger of injury from rotating impeller. Do not get too close to the fan unit, to avoid hair, clothing or jewellery being drawn into the unit. ● Risks for people (including children) with reduced physical, sensory or mental capabilities or a lack of knowledge. Fan may only be installed, commissioned, cleaned and maintained by people who can safely recognise and avoid the risks associated with this work. Children must not play with the unit.

5.3 Supply air intake within

the living area ● 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 extracted must be fitted with an non-closable, free supply air cross section of at least 150 cm², e.g. with door ventilation grille MLK.UK │ 5.
