Never spray water on the vacuum cleaner: this could be dangerous for persons and could short circuit the power supply.C421

Grounding instructions This equipment must be grounded. In case of malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. Ground the supplied cable with the appropriate clamp. In case of breakage, only use original Nilsk spare parts. Any parts that need replacing must be replaced by trained personnel. Never perform any kind of disassembly, tampering and/or maintenance on the safety systems. CAUTION! The above prescriptions, precautions and service operations must be observed, or the Nilsk Warranty for proper operation is void, the Nilsk Declaration of Conformity is no longer valid and the User is entirely responsible for the use of the machine. Dry applications [ NOTE ] The supplied lters must be installed correctly as explained in section “Primary star lter replacement” CAUTION! Comply with the safety regulations governing the vacuumed materials. Vacuuming of liquids CAUTION! Comply with the safety regulations governing the vacuumed materials. CAUTION! ■ Make sure the liquid stop device is working correctly before vacuuming liquids. ■ In case of foam, immediately stop working, turn o the machine and empty the container. ■ Regularly clean the liquid level limiting device and check to make sure that there are no signs of damage. ■ Dirty liquid vacuumed by the machine must be considered conductive. CAUTION! Do not use the machine if the liquid mechanical stop is not installed! If it's used without the oat, the machine may be seriously damaged. CAUTION! When vacuuming a mix of water and air, take care to avoid overloading the motor of the vacuum unit. The machine vacuums liquids and deposits them into the container. When the machine vacuums liquids it must be equipped with liquid mechanical stop. The liquid mechanical stop requires a special container with relevant nozzle. Before starting the machine, close the inlet on the ltering chamber with the relevant plug and t the vacuum hose in the inlet on the dust container, then t the required tool on to the end part of the hose (refer to the manufacturer's accessory catalogue or Service Centre). The liquid mechanical stop stops the vacuuming operation (the vacuuming units remain activated) when the liquid container is full; it is then necessary to turn o󰀨 the machine and empty the liquid container. The machine does not switch o󰀨 automatically.VHS110 Z22

Operation Check that the data on the machine's identication plate correspond to the Zone classication and to the maximum allowable temperature to avoid dust ignition in the work area. Check that the vacuum cleaner specications have not been modied, otherwise the Declaration of Conformity is no longer valid. Static electricity can cause sparks, with the consequent risk of explosion! Therefore, make sure the electrical socket and plug are connected to earth. Use an insulation tester to check the resistance of the earth connection from the inlet to the end of the vacuum pipe (and the antistatic hose connecting to the electrical mains on air compressed models): the resistance must be lower than 1 MΩ (106) Ohm. Check the continuity of the ground view (green-yellow protective conductors) and make sure that they are in perfect conditions. Check for loose electrical or mechanical connections. Be sure that the machine is turned o󰀨 before connecting it to an energy source. Connect the machine to an energy source outside the ATEX Zone (unclassied zone). If the machine has an ATEX electrical plug certied for the area it is used in, it can be connected to an ATEX certied socket in the same type of zone with the same rating. The operator shall take care not to generate dust clouds while cleaning the area, mostly around the vacuum cleaner itself. Do not remove hoses during operation, always wait until the machine has stopped. If a preseparator must be used, check that it is well grounded. Only use antistatic hoses, both for vacuuming and connecting the preseparator. Do not use the machine to collect large objects or particles because their collision may cause sparks. Do not rub or hit the oor with steel tools, as they can produce sparks under friction. Only use collectors and suction caps that can be replaced with original Nilsk antistatic spare parts to clean the oor. Checking the ow rate Figure 9 Vacuum gauge (2): green zone (3), red zone (1) ■ when the vacuum cleaner is operating, the pointer of the vacuum gauge must remain in the green zone (3) to ensure that the speed of the intake air does not drop below the safety value of 20 m/sec; ■ if the pointer is in the red zone (1) it means that the speed of the air in the vacuum hose is less than 20 m/s and that the vacuum cleaner is not operating in safety conditions. The lters must be cleaned or replaced. ■ during normal operation conditions, close the vacuum hose. The pointer of the vacuum gauge must switch from the green zone (3) to the red zone (1).

Upstream absolute lter replacement Figure 14 ■ Stop the vacuum cleaner. ■ Remove the absolute lter (3) by unscrewing the nut (4). ■ Cover the absolute lter (3) with a plastic bag, close the plastic bag hermetically and dispose of the lter in accordance with the laws in force. ■ Insert a new absolute lter (3) with the same ltering characteristics as the removed one. ■ Lock the absolute lter with the nut (4). ■ Close the cover hermetically by means of the band latches (1). Installation, cleaning and replacement of the separator (optional) Figure 15 [ NOTE ] Instructions describing how to t the optional kits and the relative operation and maintenance manuals are supplied together with the optional kits. CAUTION! The projection screw (5) positioned on the lter holder ring supplied with the kit must be removed; failure to do this could cause the lter to break. [ NOTE ] If there is only a dust deposit on the separator (4) allow the dust to drop through the central hole.VHS110 Z22

The separator (4) should rst be disassembled in order to be perfectly cleaned: ■ Use the band latches (1) to remove the lid (2) together with the primary star lter. ■ Unscrew the two screws (3) and remove it from the container. ■ Replace the part if it is excessively worn. ■ Reinstall the separator (4). ■ Lock it and x it by means of the two screws (3). ■ Install the lid and the primary star lter in the reverse order of removal. Immersion Separator Figure 16 The immersion separator is designed to be used for St3 explosion class dust, that is to say dust with value of Kst > 300 bar m/s (ISO 6184/1 – IFA classication: http://staubex. ifa.dguv.de/?lang=e), and/or dust with an ignition energy lower than 1 mJ. CAUTION! The machine must be 100% suitable for the collection of combustible dust. Nilsk recommends an EX-certied model in accordance with Standard 2014/34/EU. The machine must be equipped with an approved inertization system for use with water or oil to prevent the formation and reactivity of combustible gases. CAUTION! In addition to the above and for all applications involving MIE<1mJ, in addition to the use of the immersion separator, any national restrictions may be required by local regulations. Check with the appointed authorities. In addition, specic countermeasures must be taken on the machine or in the production process to be able to safely vacuum combustible dust. Nilsk customer service can suggest possible measures to increase safety when operating the machine. Use The immersion separator comprises two baskets: one on the bottom to collect the vacuumed dust, and one on the top to keep the coalescent lter in place. ■ Remove the upper basket (1). ■ Unscrew the closing band (2), remove it and remove the clamp gasket (3). ■ Remove the collection basket (4) and make sure the exhaust valve (5) is closed. ■ Pour mineral oil (20 litres into the 460mm-diameter container or 11 litres into the 400mm-diameter container, use for example Mobil Velocite Oil no. 6) into the separator (6) and check that the level raises up to the min. mark on the level indicator (7). ■ Insert the collection basket (4) into the separator (6). ■ Restore the connection between basket (4) and separator (6), insert the clamp gasket (3) and place back the closing band (2). ■ Put the lter basket back in place onto the internal ange of the separator. ■ Insert the separator under the lter chamber. ■ Connect the vacuum hose to the inlet (8) of the separator. ■ Turn on the machine and vacuum the dust. ■ Stop vacuuming dust when the oil level reaches the max. mark (about 6L of vacuumed dust with the 460mm- diameter container). [ NOTE ] The version equipped with a 400mm diameter collection container is equipped with an automatic stop device. Once the maximum level of collected material has been reached (approximately 4-5 L), the machine will stop vacuuming and the process must be interrupted. Emptying the container ■ Switch o󰀨 the machine and disconnect the vacuum hose. ■ Remove the separator and move the container to a suitable area for disposal/recovery of the material. ■ Place the separator on a workbench in a lifted position to allow easy emptying of the liquid. ■ Place a container near the drain valve (5). ■ Open the drain valve (5) and wait until the separator has fully emptied of the inerting liquid. [ NOTE ] It is advisable to interrupt the draining operation once the liquid has become muddy. [ NOTE ] It is advisable to install an additional lter on the container in order to further lter the inerting liquid to allow its correct disposal. ■ Remove the upper basket (1), unscrew and remove the clamp (2) and its gasket (3). ■ Using the lifting strap provided, slowly lift the material collection basket (4). ■ Wait a few seconds to allow more uid liquid to drain through the slots at the base of the basket (4). If necessary, tilt it slightly. ■ Remove the top cover of the basket and, if necessary, the slush lter, if installed. ■ Wash all contaminated parts, taking care to rinse thoroughly with cold water to remove all traces of vacuumed material / inerting liquid. ■ Assemble the components in the reverse order of disassembly; before reassembling, thoroughly dry all the parts that were washed. ■ Restore the container and attach it to the machine before using it again.C421

[ NOTE ] It is advisable to repeat this maintenance operation at regular and not too long intervals, even if small quantities of product are vacuumed and even if the maximum level of the container is not reached. Too long intervals could create sedimentation at the base of the basket, which would require longer times for the main- tenance operations described above. CAUTION! The maximum quantity of sludge inside the container bin shall not exceed the maximum weight of 9 kg (20 lb). This value depends on the type of material vacuumed. When this value is reached immediately empty the container. How to use the slush lter The system can also be used with a proper 300 mm-slush lter, to be installed inside the container. The lter separates and collects the slimy part, thus supplying a rst level ltration. The oil residue in the container can also be ltered with another 300 or 100 mm-slush lter, in order to make it reusable. It is suggested to use this procedure for several working cycles (3/4 cycles approximately) and to fully change the oil when it loses its uidity (high viscosity). Inerting liquid for immersion separator kit The system is designed to be used with water or oil, the characteristics of the inerting liquid must be adherent to the type of material used and the user must know and consider any reactions that they may have once they have come into contact with the liquid present in the container. To vacuum metallic powders that could have particular reactions and create dangerous vapours or gases, such as hydrogen, (following the instructions in NFPA484) inerting liquids with the following specications are recommended: Mineral oil Flash point > 100°C Viscosity at 40°C ≤10 ctS Density > 0.80 kg/l Oils with the same specications (e.g. „Mobil Velocite No.6“) can be found locally. CAUTION! Oil is combustible and should be handled in accordance with local regulations. CAUTION! The level of liquid in the collection container may have dierent levels of evaporation during use. Be sure to use the device only when the minimum level is guaranteed. CAUTION! Hydrogen is a ammable gas that is generated by the contact between metallic dust and water. Vacuuming these dusts, therefore, presents a risk of re and explosion, for this reason the intervention of qualied personnel is required. Tightness inspection Hoses check Figure 18 Make sure that connecting hoses are in a good condition and correctly xed. If the hoses are damaged, broken or badly connected to the unions, they must be replaced. When sticky materials are treated, check for possible clogging along the hose, in the inlet and on the ba󰀪e plate inside the ltering chamber. To clean, scrape the inlet from the outside to remove deposits. Filtering chamber gasket check for machines equipped with dust container Figure 18 If the gasket between the container and the ltering chamber fails to guarantee a proper sealing: ■ Loosen the four screws that lock the ltering chamber against the machine structure. ■ Allow the ltering chamber to go down until the the sealing position is reached, and then tighten the screws. If an optimal seal is not yet obtained or if there are tears, cracks, etc., the gasket must be replaced. Filtering chamber gasket check for machines equipped with Longopac

system Figure 19 Ensure that the Longopac® bag is tight with the gasket. Also check the tightness of the gasket positioned on the discharge clapet. The gasket must be replaced if it is torn, cut, etc... Disposal Figure 20 The crossed-out wheeled bin symbol on the equipment indicates that used electrical and electronic equipment must be collected and disposed of separately from household waste. The correct disposal of the equipment will help prevent potential negative consequences for the environment and human health. Electrical and electronic household equipment must be disposed of at the separate collection points in the residence area. Please note that commercial electrical and electronic equipment should be disposed of separately from the municipal waste stream. We will be pleased to inform you about suitable disposal options.VHS110 Z22
