1 MPI R.O.N.C Users Manual Maintenance and spare parts for MPI remote operated cleaning units R.O.N.C., 5, 7, and 9 - Ver. B.

2 Introduction Dear customer, Congratulations on Purchasing your MPI remote operated net cleaner from Multi Pump Innovation AS. Please take the time to review this Manual before using or working with the Remote Operated Cleaning System. MPI take pride in our customer service and should you need any more information or have Questions about MPI net cleaning systems please contact our technical support. This manual is arranged to help you get the best understanding of how to operate and maintain your equipment safely. Particular attention must be given to the safety aspects of operating and maintaining the machine. The water jetting association code of practice must be read before operating high pressure water jetting systems. Multi Pump Innovation AS.

Always turn off the main power for the high pressure generator with the main switch inside the canopy when the system is not in use.

3 Safety instructions Cleaning Unit and High Pressure Generators These systems operates at very high water pressures. It is important that hoses are kept away from sharp edges to prevent damage and leakages during use and storage. Do not expose the hoses or cables to any type of mechanical stress! Always turn off the main power for the high pressure generator with the main switch inside the canopy when the system is not in use. The cleaning units are marked with warning signs for pinch and high water pressure. Pay attention to these! Handling Use the tube frame or the lifting points when handling or lifting the cleaning unit, and let the hoses hang freely from the unit without any applied force. Lift the high pressure generators using the fork lift cut outs located on the bottom frame, or use the lifting lugs at the top of the canopy. Learn how to stop the machine if an emergency situation occurs!

6 Wheel Bearings The cleaning unit has very few wearing parts. Only the wheel bearings and the belts need to be replaced regularly. How often the wheel bearings have to be replaced depends on the tensioning of the belts and also the amount of water impurities entering the bearing. If the wheels show sign of excessive clearance when they are pushed sideways during inspection, the bearings need to be replaced. Replace wheel bearings. The wheel bearings consists of two low friction polymer rings. They will work as intended when the cleaning unit is submerged in water. Don t run the belts longer than necessary with dry bearings. They will wear out very quickly when they are dry. This is especially true if the cleaning unit has been left to dry after use without flushing, as salt particles between the polymer rings will act as an abrasives. (See Flushing ). The drive wheel has one large bearing, and the support wheel has one large and one small bearing. Always change the whole bearing to maintain the tolerances of the wheels. See drawing of drive wheel and support wheel for correct assembly. Large Bearing Small Bearing Page

7 Belts Replacing belts. It will be necessary to replace the belts after a period of use. How often depends on type of use and contamination of the nets. Follow these directions: Remove the drive unit side cover. Loosen the support wheel boss attachment screws and push the wheel towards the center of the drive unit. It may be necessary to loosen the screws for the drive wheel as well if the belts don t clear the wheels. Wheel boss attachment screws Page

8 Belt support plate and discs Replace the belt and tighten it with the boss attachment screws. Don t over tighten the belt. It is about right when there is 5 mm clearance between the belt and the belt support plate. Reinstall the drive unit side cover. 5 mm clearance Belt support plate. It is not necessary to replace this part very often, only if it shows sign of excessive wear. This can happen in locations with a large amount of water impurities or sand. Replacing discs. Discs can wear out faster when the cleaning unit is used to clean nets with sea shell growth. If this applies to the majority of the nets, it will be beneficial to replace all discs with special metal surface discs. Contact Multi Pump Innovation for further information. Use the supplied disc tool to loosen the discs, and note that the discs are available as CW rotating and CCW rotating. Replace with disc of the same type. See disc drawings and part list for details. Page

9 Nozzles and swivels Replacing nozzles. The nozzle sizes used in the discs and thrusters have been selected to insure that the system will reach the intended operating pressure at the engine s rated RPM. Changing any of the nozzles to a different size other than what has been supplied by Multi Pump Innovation may damage the equipment due to overpressure, or reduce the cleaning effect of the system. Replace worn nozzles with the same size nozzles to maintain the correct balance of the high pressure system. Please contact Multi Pump Innovation if you for some reason want to change the default setup. Always use the supplied tool when replacing the disc nozzles. It is very important that the nozzles are inserted in the exact correct angle to prevent damage to the threads in the disc. Note that it is possible to repair damaged threads with Helicoil insert kits. See drawing and part list for the discs. Swivels. A swivel needs service if water is leaking out of the vent holes in the swivel head, or if water has entered the swivel body and jammed the bearings due to corrosion. Water leakage from the vent holes is most likely a sign of a weared out pressure plunger, o-ring sleeve, or o-ring inside the shaft. Order a seal kit and change the necessary parts. See swivel part list for part number. Check orientation of the parts in the drawing, and use water resistant grease when when mounting the parts. Correct orientation for pressure plunger. Page 5

10 Flushing Replace the damaged bearings if they feel sticky or uneven when rotating the disc. If the bearings are damaged it will also be necessary to replace the shaft seals. See part list for part numbers, and drawing for orientation of parts. Upper seal ring orientation. Lower seal ring orientation. Flushing and preservation. It is very important that the cleaning unit is flushed in freshwater after use. This will prevent salt to build up in bearings and cavities. Run the belts for a few minutes when the cleaning unit is submerged, and leave it to dry afterwards. If the cleaning unit will be stored in subzero temperatures the hoses, pressure tubes, swivels, and discs must be flushed with antifreeze. This is best done by adding antifreeze to the intake water in the high pressure generator. Flush until all the water is replaced by antifreeze. Page 6
