2 Preface We congratulate you on the acquisition of a filter unit that is part of the product series TEKA- Airtech! The Airtech series is certified according to DIN EN ISO 15012-1 and examined by the IFA (Institute for Occupational Safety and and Health of the German Social Accident Insurance) regarding hazardous materials. It is approved for the welding fumes class W3 as fixed system for the extraction of welding fumes. Before you use this extraction system, read these operating instructions carefully so that you can clear up eventual questions with us already before starting up the unit. Our engineers continuously advance our devices and therefore make sure that our filter systems correspond to the state of the art. We thank you for trusting us and we wish you good luck! 3 Intended use of TEKA-AIRTECH P18 / P24 / P30 The filter unit TEKA AIRTECH is especially used to extract dusts and fumes. Restriction of application: Welding fumes containing oil, aluminium dust, grinding dust, extraction of metallic dusts, gases, water, etc. (If you are not sure, please contact the manufacturer!) When working stainless steel, the use of intake element is obligatory. The polluted air is captured via intake ducts or intake elements and enters the filter unit in passing by the ducts respectively the piping. The polluted particles are separated at the surface of the integrated filter cartridge. The cleaned air is taken in by the fan and returned to the working area via outlet jets. As soon as the resistance of the filter cartridges has achieved the maximum value or after a corresponding time interval has passed, the filters are dedusted automatically. As soon as this value is achieved, the stroboscope light located at the control unit lights up. The integrated pneumatic dedusting distributes the compressed air equally on the filter surface. Due to this, the accumulation of dust on the filter is released. (see chapter 10.1 Dedusting the filter cartridges) The dust released by the compressed air blast is collected in a dust collecting tank and can be extracted from it. (see chapter 10.3 Emptying the dust collecting tank) BA_Airtech_P18-24-30_100908_BGIA_GB..DOC 4 08.09.2010

The machine has to be accessible from all sides. If you have doubts, please contact the manufacturer. 7 Commissioning Only qualified staff is allowed to handle the used materials. To this end, every worker in charge of handling the filter unit must be instructed beforehand. Therefore you can use the instruction report (see the form attached in the annex). The instruction has to be documented by signature and the minutes have to be stored. Observe the indications on the nameplate. Only authorized electricians are allowed to connect the device. Every person that is not needed for the connection of the mains supply has to leave the danger zone. The intake ducts or the intake elements as well as the outlet jets have to be installed at the device before commissioning. Before commissioning, the filter cartridges must be coated with Precoat powder if they have not been coated yet ex works. The filter cartridges of all standard units are already coated by TEKA. Otherwise, the Precoat powder is included in the delivery in a separate bag. (If you have any questions, please contact the manufacturer!) Observe the indications of the manufacturer or contact the manufacturer! 7.1 Connection of the unit Observe the indications on the name plate. Only approved electricians are allowed to connect the unit. Every person that is not needed for the connection of the unit has to leave the danger zone. Connect the unit to the mains supply. Connect the fan to the mains supply via a star-delta connection (or optionally via a frequency converter). In case of wrong running direction of the engine (extraction performance reduced), disconnect the fan from the mains supply and change the two phases at the supply line of the frequency converter/ of the star-delta connection. Connect the particle sensor (pos. 5) to the external control. Connect the control of the dedusting procedure to the mains supply. (Observe the indications on the name plate!) BA_Airtech_P18-24-30_100908_BGIA_GB..DOC 7 08.09.2010

As soon as the control of the dedusting procedure is connected to the mains supply, the dedusting is activated. Only electricians are authorized to carry out tasks in the electrical field. Observe the indications on the name plate 7.2 Coating the filter cartridges Only coat the filter cartridges unless they have not been coated yet with Precoat powder ex works. (In case of doubt, please contact the manufacturer!) Only qualified staff is allowed to execute the coating of the filter cartridges. Every person that is not needed for the coating of the filter cartridges has to leave the danger zone. The compressed air tank must not contain any compressed air. Start the filter unit without activating the working process. Insert the Precoat powder (10g per square meter of filter surface) via the closest intake point at the suction line in relation to the filter unit. Observe the indications of the manufacturer or contact the manufacturer. 7.3 Connection of the compressed air supply An external supply may only be connected via an approved pressure hose! Only qualified staff is authorized to carry out the assembly. Every person that is not needed for the connection of the compressed air supply has to leave the danger zone. The compressed air must be dry and oil free. Attach the end piece grommet (pos. 21) to the shut-off valve (pos. 21) and connect it to the external control. Connect the pressure hose to the shut-off valve (pos. 21) via a hose coupling. The supplied operating pressure must be of minimum 3 bars and maximum 4 bars and must be adjusted according to the process. The external compressed air supply must be constructed in a way that the compressed air tank achieves the operating pressure within the break time of the valve (see operation manual of the Pulse Control). The unit has to remain easily accessible from all sides. Observe the indications of the manufacturer or contact the manufacturer. Empty the compressed air tank, disconnect the filter unit from the mains supply and avoid it from being accidentally switched on before carrying out all kinds of maintenance and repairing measures! If the pneumatic unit leaks, the filter unit must not be activated any more. Without compressed air supply, the filter cartridges pollute rapidly and the unit indicates a default (filter saturated)! BA_Airtech_P18-24-30_100908_BGIA_GB..DOC 8 08.09.2010

8 Test mode Observe the indications on the name plate. Only qualified staff should execute the test mode. Every person that is not needed for the execution of the test mode has to leave the danger zone. The unit has to be easily accessible from all sides. Observe the indications of the manufacturer or contact the manufacturer. 9 Malfunction and emergency of the filter unit All unauthorized persons have to leave the danger zone. All persons remaining within the danger zone have to wear protection equipment. In case of fire, use an approved extinguisher for the classes of fire A, B and C. In case of smoke emission, the particle sensor (pos. 26) triggers an alarm and the control closes the shut-off valve of the compressed air supply (pos. 21). and switches off the fan. The fan needs a certain amount of follow-up time until it stops definitively. In case of fire, it is possible for the fire fighters to fill the filter area of the unit with extinguishing an agent in connecting a fire hose via the so-called C-tube connection (pos.25). Only the fire brigade is authorized to make this decision. The manufacturer must be contacted. 10 Maintenance The filtration of the dust particles increases the saturation degree of the filter cartridge and reduces the extraction performance. The saturation degree of the filter cartridge is monitored electronically. In order to maintain the required extraction performance of the device, the filter cartridge is dedusted automatically. (see chapter 10.1 Dedusting the filter cartridges) The dust particles are blown off inside out from the pure gas side. The accumulation of dust is released and falls into the dust collecting tank. (see chapter 10.3 Emptying the dust collecting tank) The lifetime of the filter cartridges depends heavily on the individual conditions of application. Due to this, it cannot be determined in advance. If the stroboscope light and the red LED light up, the alarm value (basic setting = 30 millibar) has been achieved. If the stroboscope light and the red LED light up constantly even after a dedusting procedure has been carried out, the filters are saturated and have to be replaced (see chapter 10.5: Exchanging the filter cartridges). A visual inspection of the filters must be executed on a regular basis. If they are damaged, they have to be replaced. (see chapter 10.5: Exchanging the filter cartridges). After having finished all maintenance tasks, clean the work places, the filter unit and the area surrounding the filter unit. BA_Airtech_P18-24-30_100908_BGIA_GB..DOC 9 08.09.2010

When cleaning and maintaining the housing, replacing parts or when changing to another function, disconnect the filter unit from the mains supply and avoid it from being accidentally switched on. The operation of the filter unit has to be interrupted when exchanging the filter cartridges. Empty the compressed air tank before carrying out any maintenance and repairing task. Only change and dispose of the filter cartridges in sufficiently ventilated areas and in wearing an appropriate respirator mask! We recommend a respiration half mask according to DIN EN 141/143 protection level P3. Only a sufficiently qualified worker is authorized to change the filter cartridges! 10.1 Dedusting the filter cartridges The saturation degree of the filter cartridges is monitored electronically. In order to maintain the required extraction performance, the filter cartridges are dedusted automatically. During the automatic dedusting procedure, the filter unit remains activated. p - control: In order to maintain the required extraction performance of the device, the saturation degree of the filter cartridges (pos. 17) is monitored electronically. If the preset differential pressure is exceeded, the filter cartridges are dedusted automatically until the preset threshold value is achieved. Time control: In case of a time-controlled dedusting, the filter cartridges are dedusted within a set time interval regardless of the pressure. In order to adjust settings and function of the control, consult the respective instruction manual. Without compressed air supply, the filter cartridge pollutes rapidly and the extraction performance is reduced! 10.2 Compressed air supply The proper operation of the device implies a flawless compressed air supply. Only qualified staff is authorized to control the compressed air supply. The compressed air must be dry and oil free. Empty regularly the condensate produced in the compressed air tank (pos.20). (see chapter 10.4 Emptying the condensate) Control regularly if the pneumatic parts of the unit seal tightly. An external compressed air supply has to be connected via an approved pressure hose. The operational pressure must be of minimum 3 bars and maximum 4 bars. A compressed air tank serving as reserve is integrated in the pneumatic housing. The content is sufficient for one dedusting procedure. The external compressed air supply must be constructed in a way that the compressed air tank achieves the operating point within the break time of the valve (see operation manual of the Pulse Control). Empty the compressed air tank before carrying out all kinds of maintenance and repairing measures. If the pneumatic unit leaks, the filter unit must not be activated any more. Without compressed air supply, the filter cartridges pollute rapidly and the extraction performance is reduced. BA_Airtech_P18-24-30_100908_BGIA_GB..DOC 10 08.09.2010

10.3 Emptying the dust collecting tank The dust collecting tank (pos.11) has to be emptied after a certain amount of operating hours have passed. This amount depends on the produced quantity of dust, but the dust collecting tank has to be emptied at least once per week. The dust collecting tank may only be filled up to 25%! (In case of doubt, please contact the manufacturer!) Only qualified staff is authorized to empty the dust collecting tank. Every person that is not needed for the execution of the task has to leave the danger zone or must wear additional protection equipment if necessary. Before separating the device from the external compressed air supply, first wait until the automatic dedusting takes place. If the consecutive dedusting is deactivated, activate it manually via the control. Disconnect the filter unit from the external compressed air supply. Empty the compressed air tank in opening the drain cock (pos.22). (When opening the drain cock, the release of condensate is possible.) Close the drain cock (pos.22) as soon as the compressed air tank (pos.20) is completely emptied. During maintenance, wear appropriate respiration and visual protection. We recommend a respiration half mask according to DIN EN 141/143 protection level P3. Disconnect the device from the mains supply and avoid it from being accidentally switched on. (If you use the p - control, wait until the set dedusting intervals are expired and the dedusting takes place.) Open the snap fasteners (pos.15) about 5 minutes after the final dedusting procedure and unhook the tank chassis (pos.14). Withdraw the dust collecting tank (pos.11) without whirling up the dust. Remove the dust without whirling it up e.g. with the help of an industrial vacuum cleaner of the filter class H13. Store or dispose of the accumulated dust correctly in an appropriate container and according to the regulations. Push the dust collecting tank (pos.11) under the filter unit. Hang the tank chassis (pos.14) into the snap fasteners (pos. 15) and close them in a way that the tank (pos.11) seals tightly below the chute (pos.9) of the filter unit. (In doing so, check if the joint below the chute (pos.9) is damaged and replace it when necessary.) Connect the fan and the dedusting control to the mains supply. (Observe the indications on the name plate!) Reconnect the unit to the external compressed air supply. Only empty the dust collecting tank in sufficiently ventilated areas and wearing an appropriate respirator mask! We recommend a respiration half mask according to DIN EN 141/143 protection level P3.
