Page 6: General Safety Information
The design of the machines of the NA-K series allows no such unauthorised use. ESTA refuses to assume any liabilities for any such unauthorized use whatsoever! Prior to starting up for the first time, the device must be checked by an expert and a corresponding report on the results taken down in writing. - Page 7 No other than original spare parts specified by ESTA must be used for the re- placement or repair of the mains cable or lead. This ensures that the parts are splash-proof in accordance with the currently operative standards and norms and dispose of the necessary mechanical stability and strength.

Page 8: Defence Against Mechanical Dangers
2. Defence against mechanical dangers All machine parts driven by electric motors and all movable parts of the machine are covered by stationary and securely fastened protective coverings that can be removed only by means of the appropriate tools. Beware of remaining risks! In the event a protective covering that can only be taken off by the appropriate tools has been removed, the danger of injury cannot be excluded if the machine or system is running! -
Page 9: Improper Use
The device’’s installation room must have spatial ventilation or the exhaust flaps must be vented out the roof through an appropriate, steadily rising pipeline. The device must be operated only with the droplet separator installed and the sludge pail connected. For high filtration efficiency, a minimum dust load of 5 g/m³... -

Page 11: Functional Description
6.2 Functional description With all devices of the NA-K series, a radial fan is employed that generates the volume flow and the negative pressure needed for extraction. The dusty air exhausted from the processing machine is guided through a pipeline or a suitable conductive or dissipative hose connection to the device’’s intake port. -
Page 12: Delivery And Mounting
7 Delivery and mounting Failure to comply with the safety instructions can lead to a fatal explosion (of dust and/or gas). The wet spray separators of the NA-K series are delivered on a wooden pallet (in lying condition). The machines are covered with a protective PE film. After removal of the protective covering, a crane can be used to lift it off using the lifting eyes that exist at its upper part and to move it to the provided place of operation. -
Page 13: Connection Of Processing Machines
7.1 Connection of processing machines Extraction hoods, extraction conduits and/or extraction hoses need to be connected to the NA-K in an electrically conducting manner to avoid electrostatic charging. To correctly extract from a dust-producing machine, a conductive pipe or hose connection and the electrical connection must be created between the processing machine to be exhausted and the NA-K. -
Page 14: Commissioning
The electrical coupling between the dust-processing machines and the NA-K dust extractor must, in compliance with the enclosed documents relating thereto, imperatively be realised in a professional and skilled manner. Prior to taking it into operation, the system needs to be checked for correct functioning! 8. - Page 15 For control purposes, the water level can be read from the device’’s inspection window and absolutely must be between the ““min”” and ““max”” levels. Because the water pressure at the NA-K’’s inlet valve can vary from place to place, the time necessary for water filling also varies.

Page 16: Alternative Water Level Control
Once the functional check has been performed without findings, the NA-K is ready for being used within the limits of dust extraction applications it has been specified for. Please contact the ESTA maintenance service whenever uncertainties or unsol- vable problems occur. ESTA maintenance service:... -

Page 18: Inspection And Servicing Intervals
9.2 Inspection and servicing intervals According to TRGS 560 (5.9) the separation equipment must be maintained regularly. The regular maintenance comprises following procedures: 1. The daily inspection: (To be performed by the user of the dust extractor.) Visual inspection of the water level in the NA-K through the inspection window. for leaks between the sludge pail and the device’’s housing. - Page 19 3. The annual inspection: A sticker on the machine indicates the date at which the machine has last been inspected by ESTA! (To be performed in cooperation with the ESTA maintenance service.)

If the pressure controller’’s pre-set value (see ““Technical data””) is too weak for the operational use conditions (long suction distances and small tube diameters), this can be adjusted upon consultation with ESTA maintenance services. Changes to the pressure switch’’s settings are to be made only in consultation with ESTA. -

11. Cleaning When using the NA-K for the separation of aluminium dusts, always make sure to perform all cleaning and/or maintenance works in compliance with the requirements specified in BGR 109 (4.9.1) and to keep corresponding records. The formation of potentially explosive hydrogen gas areas can thus be avoided! The persons charged with the execution of cleaning works must have been trained in the handling of the extracted health-hazardous substances and... -
Page 28: Cleaning Of The Demister
11.3 Cleaning of the demister The NA-K is equipped with a so-called demister. The demister separates the water drops that still remained in the cleaned air prior to leaving the device. Dirt may accumulate inside the flow ducts of the device after longer operation periods. The accumulated dirt leads to an increased air resistance in the device and thus to a reduced extraction performance. -
Page 29: Disposal
12. Disposal The persons charged with the execution of cleaning works must have been trained in the handling of the extracted health-hazardous substances and been instructed in how to deal with them. All such works are to be performed without affecting non-involved third persons! Before disposal work begins, the NA-K must be turned off at the main switch and be secured against reactivation. -
