REGULAR TESTING OF THE APPLIANCES Person responsible Test certificate No. Test date Company Name The fluid spraying equipment is intended in particular for surfacing (e.g. airless paint spraying equipment, two-component coating equipment). The operator must ensure that fluid spraying equipment is tested for proper operation after an operating pause of more than 6 months, and at least every 12 months by a competent person The operator must ensure that the test results are properly recorded in writing for every fluid spraying equipment...

GRACO ECOMIX 2000 BASIC VERSION, BASIC APPLIANCE, COMPLETE APPLIANCE Read and follow up the operator manual and the safety instructions before taking the pump into operation In this manual important information is marked with the following symbols: Information affecting your safety Important operational directions The original manufacturer's nameplate is on the 2K device.
CORRECT USE ECOMIX 2000 equipment is exclusively manufactured for common applications in surfacing technology, for spraying or discharging or similar work with 2K fluids. Any other purpose above and beyond this is considered as incorrect use. We are not liable for any damage or injury resulting from this;...
DESCRIPTION OF FUNCTIONS Compressed air is fed from a pressure tank to the 2K device via a tube or hose line and a pressure regulation valve , if possible through a separate air filter The air supply from the pressure tank to the 2K device can be interrupted by the ball valve The ball valve is used to release condense manually, - an automatic moisture trap is recommended here.
Page 7
− When compressed air supply needs to be installed, the relevant accident prevention regulations, safety rules and user information must be respected, in particular the information supplied by the compressor manufacturer. The connection between the 2K device and the compressed air line must be flexible to avoid rupture caused by vibration.

AIR EXHAUST SILENCER The sound emission of an air powered 2K device is damaging to hearing in the absence of a silencer [> 115 dB(A)]. As there is a relation between sound absorption and the formation of ice on the air motor control system, the sound level cannot be reduced with a silencer as much as would be desired [not to 70 dB(A)].
Page 9
The diameter of the suction line is designed to enable suction of fluids with a kinematic viscosity of up to 750 mm²/s (cSt) by the 2K device without difficulty. A higher viscosity rating can result in reduced suction performance, or even interrupted suction, that can be identified by an increasing pressure drop during the change of direction (pulsating pressure).
Page 10
FLUID PRESSURE SYSTEM The fluid pressure system consists of the hose line and the discharge or spray gun. In some cases a pressure regulation valve has been installed as well. A pressure regulation valve (mechanically or pneumatically controlled) can be fitted at the fluid outlet of the 2K device.
THE FLUSHING PUMP The flushing pump is a regular part of the 2K device. It is supplied with the appropriate user information.

should be connected to appliances and the earth by soldering, welding or stable screw fittings. Do not use chains. When making connections or during repair work, in particular to pipelines, ensure that the conductive path is not interrupted by non-conductive parts. The grounding connection must be tested for correct working conditions by a qualified engineer.
Page 13

START UP FILLING THE WET CUP Fill the coupling housing up to the middle of the filling tube with solvent. See manual 6000354 section B.13.50.01-B for the start up of the hydraulic valves The solvent used must be compatible with materials to be used later;...
Page 15
FLUSHING THE 2K DEVICE Each every 2K device is factory-tested after assembly with an anti-corrosion liquid. It is necessary to flush out the rest of this liquid and any other contaminants that might have entered during installation thoroughly with solvent (flushing agent). The solvent must be compatible with the fluid to be processed later;...
Page 16
Flushing the measuring installation: 1. Suction installation of the flushing pump in solvent 2. Move the lever up to the “MEASURING” position 3. Hang discharge units in an empty vessel 4. Open the fluid pressure valves, when installed (turn left) Flush sections “A” and “B” as described above.
Page 17
ADJUST THE MIXING RATIO Run the device slowly and stop it at the end of its upward stroke (“SPRAY” switch “OFF”). Insert the bolts into opening Run the machine slowly until the lever recess touches the bolt; switch off. To set the mixing ratios, loosen the retaining screws (4 in all) and...

APPROXIMATE VALUES (A GUIDE) − for approximate setting of mixing ratios The middle scales show the theoretical mixing ratios Base material components (A) in accordance with the combinations of the displacement pump Hardener components (B) (specified in the matrix). The upper and lower scales are auxiliary values and are used to ease renewed adjustment, e.g. after repair.
Page 19
IMPORTANT INFORMATION CONCERNING STARTING UP AND OPERATION Only work in well-ventilated areas in view of health hazards, fires and explosions. The 2K device should only be operated dry for short periods of time under supervision and only with low air inlet pressure. Dry operation after the fluid has passed through must be strictly avoided.
OPERATION (Also refer to manual 6000354 section B.13.50.01-B) Start up Open ball valve for air pressure Turn air pressure regulation valve "FLUSH" up to 3 or 7 bar respectively Turn air pressure regulation valve "SPRAY" up to spraying pressure Shut down The section of the 2K device containing the mixed material (valve unit, mixer, fluid pressure hose, spray gun) must be flushed for longer stops (also refer to page 32) exceeding the processing time, overnight and during the weekend.
MAINTENANCE AND INSPECTION, REPAIR MAINTENANCE AND INSPECTION The ECOMIX 2000 2K devices require little maintenance • Topple the anchor support forward – remove 2 screws – and check the solvent reservoir from above every week. • The detergent should be replaced after discoloring or once every month −...
Page 22
ECOMIX 2000 2K devices must be checked daily • Check the solvent in the wet cup every day. The solvent level must be visible in the filling sleeve , preferably in the center. When the solvent has visibly discolored, it must be changed. Discoloring can hardly be seen at the hardener side, so it must be changed more regularly here.
Page 23
REPAIR Qualified engineers (VBG 87) must carry out repairs. Use only genuine replacement parts. Our obligation to replace 2K equipment is forfeited when non-genuine replacement parts are used (Product Liability Law of 15 December, 1989). All parts that are to be re-used should be cleaned thoroughly after dismantling. Do not damage sealing surfaces;...

THE SYSTEM COMPONENTS ONLY FOR ND MODELS - IMPORTANT INFORMATION FLUID PRESSURE CONTROL SYSTEM The fluid pressure control system consists of a pressure regulation valve P4-VP and a manifold with bursting disk The fluid pressure control system is installed in front of the fluid pressure system Choice of G 3/8 or G 1/4 The pressure regulation valve P4-VP controls a max.
Page 36
Respect the following when installing or replacing a burst disc: Direct the outlet of the burst discs 2.2 so that the draining material can endanger neither persons nor equipment. It is possible to connect a hose. Breaking the burst disc can generate recoil forces of approx. twice the breaking pressure. This should be taken into account with regard to the mounting or layout of other elements.

NOTES SELF-MONITORING When ECOMIX 2000 devices are operated unsupervised, any dangerous situations can be prevented with the automatic self-monitoring feature. Stop valves are very suitable. When a set limit value is exceeded (e.g. excessive stroke frequency as a result of a ruptured line), a stop valve will interrupt the compressed air supply to the 2K device. MONITORING SYSTEM If the paint supply stalls on the ECOMIX 2000 equipment, a monitoring system will ensure that the processing time (pressure time) of the mixed material will not be exceeded.
USER INFORMATION The user information about the ECOMIX 2000 program, in accordance with the sales catalogue 03.2060. The user information - operating instructions- contains all necessary information.
