2.4 Safety systems Several safety systems have been conceived during the multi spray unit design and manufacture to safeguard the operator, in compliance with pr EN 12621 Directive about paint.
Safety pictograms Some pictograms showing the safety warnings to be followed by anyone who is going to use it can be found on the pump. WARNING THE MANUFACTURER IS NOT TO BE HELD RESPONSIBLE FOR DAMAGE OR ACCIDENTS TO PEOPLE OR THINGS DUE TO NON-COMPLIANCE WITH THE PRESCRIBED RULES. THE OPERATOR IS THE ONLY PERSON RESPONSIBLE. 2.5 Workable products MULTI SPRAY ANEST IWATA pumps are conceived to paint ferrous material, wood and plastic.
3. OPERATION 3.1 Operation description Multi spray pumps are composed of two main parts: the pneumatic motor and the pumping unit; the pneumatic motor is provided with a pneumatic piston and with a switch for the change of the movement direction. The pumping unit is made up of an anti-wear chromium plated suction tube and rod. The packing can be adjusted. The motor’s straight and alternate movement creates an equivalent movement in the pumping unit.
4. INSTALLATION AND START 4.1 Check the purchased product Before using the pump, make sure it has not been damaged during transport or storage. Also check that all standard components are inside the packaging. 4.2 Conditions for the installation - The installer must know the ATEX classification of the installation area and also the risks deriving from a potentially explosive atmosphere, especially explosion and fire, so that he can adopt the suitable protection measures.
WARNING - CHECK THE PROPER TIGHTENING OF ALL FITTINGS, SINCE THEIR SUDDEN OPENING CAN SERIOUSLY INJURE PEOPLE. WARNING - CONSULT THE LOCAL CODE FOR DETAILED INSTRUCTIONS CONCERNING THE EARTHING OF THE WORKING AREA AND THE TYPE OF SYSTEM USED. - THE EARTH CABLE (INCLUDED IN THE SUPPLY) MUST HAVE A MINIMUM SECTION OF 1.5 MM2. - ONE END OF THE CABLE MUST BE EARTHED WHILE THE OTHER MUST BE CONNECTED TO THE COVER OF THE PNEUMATIC MOTOR PACKING. 4.4 Cautions 1.

5. USE 5.1 Use This section describes the multi spray unit use in compliance with the safety standards in force. We recommend reading it carefully. LIMITS AND CONDITIONS OF USE Any change of the unit can be carried out only if authorised by ANEST IWATA EUROPE technical service. If the change is not authorised, the unit is not considered as ATEX approved. Environmental condition Environment temperature: min. +5°C; max.
5.4 Prewash and adjustment of the upper packing. [Ref. figure 2 page 17 and figure 3 page 18] 1. Make sure the pump has been properly installed; (see point 4.3) 2. Immerse the suction hose (A), in the cleaning liquid (clean solvent or water according to the purchased model). 3. Place the ball valve (E) in the proper position. 4. Open the recirculation valve (C). 5. Loosen the upper packing adjusting cup (D). 6.
5.5 Start [ref. figure 2 page 17 and figure 3 page 18] Before operation, start the pump by following the operations below: 1. Dip the suction hose (A) in the tank with the product to be pumped. 2. Open the recirculation valve (C) for paint recirculation. 3. Lift and gradually turn the pressure reducer knob (G). Adjust it to a pressure slightly higher than 2.0 bar, to enable the pump to release the air. 4. Close the two-way valve for paint recirculation (C) and release the air through the gun, as well. 5.
5.6 Daily interruptions [ref. figure 2 page 17 and figure 3 page 18] 1. Upon interrupting the use of the pump: - It is not necessary to disconnect the air supply, if the interruption is short. - If the interruption period is long, turn the ball valve (E), discharge the air from the circuit and open the recirculation valve (C) to release the residual fluid pressure. 2. When the pump is stopped at the end of the working day: - Clean the fluid ducts.
5.8 Pressure release process WARNING 1. Close the air supply to the pump by turning the pressure reducer adjustment anticlockwise down to 0 bar. 2. Enable the safety catch of the multi spray gun trigger. 3. Make sure the recirculation pipe is not clogged, then gradually open the recirculation ball valve and leave it open. 4. Hold the gun tightly and lean it against the metal vessel with the paint.
6. MAINTENANCE AND INSPECTION 6.1 General notes - Observe the intervals of inspection and ordinary maintenance to ensure suitable working conditions and explosive-proof protection. - Before repairing or maintaining the internal parts, wait for the complete cooling of the unit, to prevent you from coming into contact with hot parts thus avoiding any burns. - After maintenance, make sure that all the safety measures are restored. - At the end of maintenance/repair clean the unit.
6.4 Disassembly and re-assembly procedure WARNING Before starting any maintenance operation, remove the air supply pipe and make sure the inner residual pressure has been released. 6.5 Motor group disassembly 1.
