2.1 Terms of sale Delivery is made ex works Ochsenbach and is subject to our Terms of Sale and Delivery.
2.2 Guarantee We grant guarantee as described in our conditions for sale and delivery under point VII. liability for defects. Obvious defects must be reported to us immediately, at the latest within 8 days.
2.3 Accident prevention regulations Use of the equipment is governed by the applicable accident prevention regulations. The "Guidelines governing liquid jet pumps" issued by the central association of the employers' liability insurance association – Chemicals Committee – must be observed in all cases. The brochure containing the "Guidelines governing liquid jet pumps" can be ordered from Carl Heymanns-Verlag KG, Gereonstrasse 18-32, D-50670 Köln, quoting the order num-ber ZH 1/406.
2.4 Owner and operator of the equipment The owner and operator of the equipment are also responsible for the equipment. The Operating Manual is an integral part of the equipment as required by prevailing law. Care must therefore be taken to ensure that the columns on the cover sheet (type, serial num-ber and date of delivery) are completed by the dealer or, if necessary, by the customer when the equipment is delivered. 3 Area of use: The WALTER MRS-B series can be used to spray hot and cold water upt to 70°C. 4 Technical data See entries on cover sheet. 5 Description of equipment: The pump units are not encased and equipped with heavy-duty 3-piston plunger pumps and electric motors. The power supply must be safeguarded accordingly. 6 Startup
6.1 Acceptance standard The entire mixer washout system (including the rotating nozzle systems RD3) may only be taken into operation after acceptance and instruction by WALTER Gerätebau GmbH or by a specialized company authorized by WALTER Gerätebau GmbH!
6.2 Lubrication instructions The lubrication instructions must be followed and carried out in accordance with the pump operating instructions (s. item 9.2).
5
6.3 Water withdrawal Water from mains supply: The water pressure in the water mains must be at least 3 bar, but not more than 8 bar. For water pressure higher than 8 bar it is necessay to install a pressure reducer with pressure gauge behind the spigot. Fit in feed hose 1 1/4“ resp. 1 1/2“. Check that the minimum inflow corresponds with the delivery rate, see section 3.0. If the inflow is too low, the system will be switched off by the integrated water shortage cutout.
6.4 Security advice The pump unit may not be connected to the public water mains supply without a network separation.
6.5 Deair piping system and pump Open the valve at the withdrawal point, switch on the system and let it run until a full water jet emerges from the supply. Switch the system off again.
6.6 Connect spraying facility to water supply Switch on the system – open the spray gun – the unit is now ready to wash with the hot or cold water supplied.
6.7 Restarting The main equipment parts, such as safety mechanisms, spray gun, pump and hose lines must be examined each time before restarting the system to ensure that they are in good working order. 7 Mode of operation
7.1 Manual operation For safety reasons, before opening the mixer to carry out a final cleaning with the hand gun, the air supply to the changeover valves must be shut off (see photo 1)! Afterwards the button „Hand“ must be pressed. The pump starts and runs until the button „Off“ is pressed. If no water is taken, the pump delivers continuously without pressure in the bypass (until it is switched off due to overtemperature of the pump unit). Before restarting the automatic program, the changeover valves must be supplied with air again (see photo 2).

7.2 Overpressures and kickback forces The following overpressures and kickback forces are produced in the spraying facility when working with hot or cold water:
7.3 Automatic Operation (mixer 1, mixer 2 etc.) Automatic operation is only possible when connected to the release for mixer cleaning. To do so press „mixer 1“ („mixer 2“). If the automatic operation is started, both pumps start running and the single cleaning heads are activated time-dependently via the PLC control. Automatic operation is also possible via remote control (at the mixer control desk).
7.4 Mode of operation of the safety facility The entire delivery capacity of the pumps being used is led through the bypass valve which maintains the set pressure and returns excess delivery quantities back to the pump via the bypass. 8 Switching off
8.1 Breaks in work Important: Before interrupting the work, always close the shutoff valve for pressure water at the sup-ply point. Open the spraying facilities so that the liquid pressure in the pressure hose can escape through the nozzle. Close and secure the spraying facility (spray gun) when the pressure has been relieved. 8.2 Maintenance work For maintenance work set the main switch to „0“ and secure against unauthorized switch-ing on!
8.3 Switching off in case of risk of freezing For temperatures below +3°C it is necessary to discharge the water from the pump and the piping system during standstills. For this purpose we offer a manual protection against freezing as an option (see page 22). The pump unit must be installed in a frost-protected area. 9 Maintenance and Care
9.1 Follow pump operating instructions.
9.2 Check oil level. Important After-sales service and oil change every 400 operating hours, however every 6 months at the latest. The formation of condensation in the gear box must be monitored. Check that the safety valve, pump collars, float-operated valves and safety mechanisms are operating correctly and replace gaskets if necessary. 9.3 Clean filter Important: The filter at the dirt trap of the water inlet of the pump must be cleaned regularly.

Turn the motor protection switch on again. The single pump systems can now be checked by pressing the switching element on the respective motor contactors. According to the regulations (RFL), the pump unit must be inspected by an expert (person who, on account of training and experience, has sufficient knowledge of the relevant regu-lations to judge whether the equipment is in safe working order) whenever necessary, but at least every 12 months in order to ensure that it is operating safely. The results of such inspections must be documented in writing. You are therefore urgently recommended to conclude a service agreement ensuring regu-lar, expert inspection of the equipment. The forms for a service agreement are available without obligation from our customer ser-vice department. 12 Troubleshooting
12.1 System indicates default: a) check feed pressure in water line b) clean filter c) check float valve d) water feed temperature is too high e) check pump motor

Sicherheitsvorschriften und Garantie Die Garantie beträgt 6 Monate nach VDMA. Es ist ein Sicherheitsventil gemäß den Richtlinien für Flüssig-keitsstrahler vorzusehen, das so eingestellt ist, dass der Be-triebsdruck um nicht mehr als 10 % überschritten werden kann. Bei Nichteinhaltung dieser Vorschrift sowie bei Überschreiten der Temperatur- und Drehzahlgrenze erlischt jegliche Garantie. Beim Betrieb der Pumpe muss die angetriebene Wellenseite und Kupplung durch einen bauseitigen Berührungsschutz abgedeckt sein. Vor Wartungsarbeiten an Pumpe und Anlage muss sicher-gestellt werden, dass Druckleitung und Pumpe drucklos sind! Saugleitung verschließen. Versehentliches Starten des Antriebsmotors durch geeignete Maßnahmen vermeiden (Sicherungen herausschrauben). Vor Inbetriebnahme Pumpe und druckseitige Anlagenteile drucklos entlüften. Ansaugen und Fördern von Luft oder Luft-Wassergemisch sowie Kavitation unbedingt vermeiden. Kavitation bzw. Kompression von Gasen führt zu unkontrollierba-ren Druckstößen und kann Pumpen- und Anlagenteile zerstören sowie Bedienungspersonal gefährden! Pumpen sind geeignet zur Förderung von sauberem Wasser oder anderen nicht aggressiven oder abrassiven Medien mit ähnlichem spezifischen Gewicht wie Wasser. Keinesfalls dürfen explosive oder brennbare Medien gefördert werden.
Safety and Warranty Rules There is a 6 month warranty in accordance with VDMA guidelines. Pump operation without safety valve as well as any excess in temperature or speed limits, automatically voids the warranty. The safety valve must be regulated in accordance with the guidelines for liquid spraying units so that the maximum admissible operating pressure can not be exceeded by more than 10%. When the pump is in operation, the drive shaft end and the cou-pling must be covered up by either a contact-protector or by a coupling bell. Pressure in discharge line and in pump must be at zero before any maintenance to the pump takes place. Close up suction line. Disconnect fuses to ensure that the driving motor does not get switched on accidently. Make sure that all parts on the pressure side of the unit are vented before starting the pump. In order to prevent air, or an air-water-mixture being absorbed and to prevent cavitation occurring, the pump-NPSHR suction head and water temperature must be kept under control. Cavitation and/or compression of gases lead to uncontrollable pressure-kicks which can ruin pump and unit parts and also be dangerous to the operator or anyone standing nearby. Plunger Pumps are suitable for pumping clean water and other non-aggressive or abrasive media with a specific weight similar to water. On no account may Inflammable or explosive media be pumped.
