1. Product identification ® The Nanogun Airmix O gun markings will allow differentiating between the 120-bar and the 200-bar model configuration. 1.1. Version identification 1.1.1. On the gun barrel ® The marking on the barrel is the same across the entire Nanogun Airmix O range.
This control step pertains to each of the electrical and electronic components as well as to the set of very specific program(s); you should contact your subsidiary, distributor or regular SAMES KREMLIN representative, who will inform you of the appropriate steps to take.
WARNING : Before using the Nanogun Airmix O gun, be sure that all operators • have received preliminary training by the SAMES KREMLIN, or by the Distributors it has certified for this purpose. • have read and understood the user’s manual as well as all installation and use rules listed below.
• The floor where the operator works must be antistatic (either unclad concrete flooring or a metal grating). Never cover the floor with an insulating covering. In potentially explosive locations, the floor assemblies must be antistatic, in accordance with Standard EN 61340- 4-1.
WARNING : Shutting off the compressed air supply line does not prohibit triggering high voltage should the trigger be activated. • The operator must have been trained by a SAMES KREMLIN company or else by the ® Distributors it has certified for this purpose, in order to carry out the Nanogun Airmix gun maintenance operations.
2.4.1. Products used Given the diversity of products used and the impossibility to inventory the characteristics of these products, SAMES KREMLIN cannot be held liable for: • for any incompatibility in the materials of products used whenever they come into con- tact with the materials listed below: •...
3. Description of spray gun and GNM 6080 control module ® The Nanogun Airmix O guns are for spraying water-soluble or water-dilutable water-based paint. Sprayed liquids must be non-flammable (defined in the draft standard pr EN 50059:2016 Annex C) and strongly conductive. The use of any other type of paint is excluded.
“Default Acknowledgement” button (Rep. 3). Generator default: This default combines all internal generator defaults. If it is impos- sible to acknowledge this default, the problem would require a service call by the repairs department, please contact SAMES KREMLIN. Index revision : A 7118...

Low-voltage connection default: The generator fails to detect or no longer detects the presence of the gun. After shutting off the power supply, verify the gun/genera- tor connection. High-voltage default: Defaults specific to gun operations related to the high voltage: •...
4. Technical characteristics 4.1. General characteristics of the guns Type of spray Flat Original head assembled Maximum incoming paint pressure 120 bar 200 bar Incoming compressed air pressure 6 bar ± 1 bar Min/max ambient temperature 0°C - 40°C Maximum water flow rate See table below Spray width at 25 cm See table below...
Note: The spraying air pressure must be set between 2 and 3 bars (4 for the K70 gauges); below this, the spraying becomes less precise and above the jet becomes more dynamic and the hol- low cone's benefits are reduced. 4.3.
5. Operations Pressing the trigger serves to delay the order to open the air valve, then activation of the high voltage, and lastly the paint nozzle needle. The high-voltage order may be inhibited by shifting the gun switch. ® The Nanogun Airmix O gun is equipped with a magnetic sensor that detects the trigger posi- tion.

8. Use 8.1. Recommendations regarding the paint to be used In general, all the paints and varnishes used with conventional pneumatic guns are used nor- ® mally with the Nanogun Airmix O gun. the pigments contained in the paint should be less than 5 μm.
8.2. Spraying rules Regardless of the type of nozzle, the quality of spraying depends on both the supply pressure and the product viscosity: as viscosity increases, pressure must also rise, yet the final outcome is also influenced by the product’s dilution. A few key points: •...
The non-exhaustive list below indicates the primary cases of poor paint spraying equipment use. WARNING : SAMES KREMLIN would like to recall therefore that it is essential to comply with the prescriptions listed below. It is prohibited to install the control module in an explosive atmosphere.

10.3. Paint hoses It is not necessary to remove the electro-pneumatic coupling (see § 10.2 page 26) to complete these operations. • Step 1: Unscrew the locknut of the cable Step 1 gland using a 27 flat wrench, remove the cable gland from the bracket.
10.4. Spraying head assembly Step 1 • Step 1: with the multipurpose wrench (Ref.: 900012843), unscrew the head ring. • Step 2: Extract the head nozzle using the mul- Step 2 tipurpose wrench. Do not use your fingers. If necessary, replace the head seal. For the reassembly step, proceed in the reverse order.
10.5. Replacement of the head electrode. Disassembly: • Step 1: Extract the conductive PTFE washer. Insert the blade of the screwdriver under the washer through one of the two slots at the rear of the head(do not use the housing where centering located).
Page 30
• Step 4: With the flat nose pliers, remove the small PTFE tube surrounding the electrode. Check that there are no residues in the pas- sage of the electrode. If necessary, manu- ally push a drill bit or a metal rod of 1 mm in the hole.
Page 31
• Step 3: Clip the conductive PTFE washer. Replace it if necessary. It is recommended not to reuse the washer more than 3 to 4 times, and it must not be able to be removed without the aid of a tool. •...
10.6. Barrel • Step 1: Unscrew the seat casing using a 13- mm pipe wrench. Step 1 Then remove it.
