to convey greasy air, e.g. in combination with range hoods with exhaust air operation. Read all the safety instructions. Risks for children and people 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. Danger of injury due to suction from fan and rotating impeller. Hair, clothing, jewellery etc. may be pulled into the fan if you get too close to it. During operation always keep far enough away to prevent this from happening. Danger of injury if foreign bodies are inserted into the unit. Do not insert any objects in the unit. A fan that is not installed correctly may result in non-intended operation or impermissible operation. Operation is only permitted with a correct installation position (see “TOP” on unit), with mounted design cover and outer protective grille. The fan may be operated only if the protec- tion against accidental contact with the impeller is guaranteed to be in accordance with EN 13857. Risk of injury and health risk in the event of changes or modifications or if components which are not permitted are used. The unit may only be operated with original components. Changes and modifications are not permitted and release the manufacturer from any guarantee obligations and liability, e.g. if the unit is drilled at a point which is not permitted. Danger of injury when working at heights. Use appropriate climbing aids (ladders). Stability should be ensured, if necessary have the ladders steadied by a 2nd person. Ensure that you are standing securely and cannot lose your balance and that there is no one under the unit. Risk of death from carbon monoxide when operating with air-ventilated fireplaces. When operating with air- ventilated fireplaces and in "air extraction" installation position, a sufficient fresh air supply must be ensured. The maximum permitted pressure difference per living unit is 4 Pa. The consent of a professional chimney sweep is needed in all cases. Danger of electric shock from operating with the unit not fully mounted. Before taking off the electronics cover, shut down all supply circuits (switch off mains fuse), secure against being accidentally switched back on and position a visible warning sign. Only operate the fan when it is completely installed. Do not commission a damaged unit. Danger if the relevant regulations for electrical installations are not observed. Before installing the electrics, shut down all supply circuits, deactivate the mains fuse and secure it so it cannot be switched back on. Attach a warning sign in a clearly visible place. Be sure to observe the relevant regula- tions for electrical installation; e.g. EN 50110-1, in Germany this is particularly VDE 0100, with the corresponding parts.3. Safety instructions and warnings │ UK

A mains isolation device with contact openings of at least 3 mm at each pole is mandatory. Only connect unit to a permanently wired electrical installation with NYM-O / NYM-J, 3 x 1.5 mm² or 5x 1.5 mm² (depending on unit type) cables. The units may only be operated using the voltage and frequency shown on the rating plate. The degree of protection stated on the rating plate is only guaranteed if installation is undertaken correctly and if the connection cable is correctly guided through the cable grommet(s). The grommets must tightly seal the cable sheathing. Unit may be energized even when at a standstill and may be switched on automatically by sensors, such as for time delay or humidity etc. Maintenance and fault finding only permissible when carried out by trained specialists. Exercise caution when handling packaging materials. Observe applicable safety and accident prevention requirements. Store packaging material out of the reach of children.

Fan is turned on/off using a switch (e.g. light switch). Depending on the unit variant with start delay, with H and B units operation is automatic or controlled with an additional switch. In the event of thermal overload, the unit switches off. Wait until the motor has cooled down. Cool-down time can be up to 10 mi- nutes. Unit switches back on automatically after cooling down.

● Small room fan for extracting air from rooms. ● ECA 100 ipro with fixed internal grille. ● ECA 100 ipro K with electrically operated internal shutter. ● Two performance levels as standard. ● Models Standard: Can be operated at two levels with an optional double switch.UK │ 5. Product information

VZC and KVZC: Model with start delay and overrun time. F and KF: Model with light sensor, start delay and overrun time. Switch-on intensity (at fan) min. 30 lux. Switch-off intensity (at fan) max. 1.7 lux. H and KH: Model with humidity control (fully automatic), start delay and overrun time. B and KB: Model with motion detector and overrun time. Without start delay. Monito- ring range of motion detector horizontal 100°/vertical 82°. 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 operating program starts when the light is switched on (

chapter 9.3). 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.

Environmental conditions and operating limits │ UK

6. Environmental conditions and

operating limits ● Maximum permitted temperature of the air medium + 40 °C. ● 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. ● Storage: Store unit exclusively in a dry location (-20 to +50 °C).
