Main components 5 Main components 5.1 Components RA 050 A B C D E F G H Lid Collection container Chassis Side channel condenser Mains plug Motor protection switch Hose Suction socket 5.2 Function description RA device Suction turbines in the drive unit generate a vacuum through the filter in the collection container via the hose and the hood. The raw air is sucked in through the nozzle and the suction hose or the pipes. Coarse particles fly against the baffle plate and fall from the air flow into the collection container. Smaller particles and dust are separated at the surface of the filter material when passing through the area filter. The pure air that was cleaned in this manner is blown back through the hood to the suction turbines and the muffler exhaust hose in the working room. 15/41

Initiation 6 Initiation Only use with safety shoes (acc. to EN ISO 20345) 6.1 Assembly Instructions Check centric seat of the lid on the collection container Connect and install device electrically according to VDE-provision. Create all hose and pipe line connections. 6.2 Initial operation CAUTION Ensure that proper seating of the collecting container on the bottom plate! The industrial vacuum cleaner must be correctly installed, with all necessary lines and tubes connected. The operating conditions must match the data on the plate and the supplied documentation, if applicable. The cooling air duct must be fully functional, the cooling effect must also not be impaired by soiling of the cooling surfaces. Start up the industrial vacuum cleaner with the on/off switch located on the drive unit. If the suction system has a control unit, please observe the information provided in the circuit diagram! Start up the industrial vacuum cleaner with the on/off switch located on the drive unit. A 16A fuse is required on the building side, due to the high motor capacity. Make sure that the power supply cord is not damaged by being run over, crushed, tugged etc.. Stop the industrial vacuum cleaner immediately if necessary! The power supply cord must be regularly inspected for signs of damage or ageing! Connectors of power supply cords must at least be splash-proof! 6.3 Incorrect rotational direction If the rotational direction is incorrect, drives with side-channel compressor convey the suction air in the inverse direction, i.e. an air current is discharged from the raw air suction nozzle of the suction system. If this is the case, the suction system must be switched off immediately, the mains plug removed from the mains socket and the technical personnel informed, so that the phase conductors in the mains lead can be reversed. 6.4 Check the following before switching it on: All filters must be inserted correctly. The extraction hose and the accessories or pipe lines must be connected correctly. 16/41

Operation 7 Operation 7.1 Operation 7.1.1 ON / OFF switch Three-phase current 0 = Motor "OFF" 1 = Motor "ON" 7.2 Suction process NOTICE When vacuuming up dust only immerse halfway, so that sufficient air is absorbed Insert desired suction nozzle into the plug-in cone on the handle of the suction tube. Do not immerse the entire area of the nozzle! Hold the nozzle diagonally to the suction surface, so that both air and liquid are absorbed 17/41

Operation 7.3 Emptying the collecting tank WARNING Before starting work remove the plug from the wall socket! Suitable work gloves must always be worn when carrying out maintenance and service tasks, in order to prevent injuries and soiling with contaminated substances Respiratory protection (EN 149:2001) Use protective glasses (acc. to DIN EN 166 1349-BT) Use protective clothing (acc. to EN 13982-1) Remove suction unit Unlock the hood Remove hood Collecting container remove and clean During insertion of the collecting container for correct seating eighth Put the cover on the Collecting container and pay attention to proper fit; Baffle plate on the intake hood locked Connecting the suction hose unit 18/41

könne Troubleshooting and fault elimination 8 Troubleshooting and fault elimination 8.1 Safety instructions WARNING If harmful substances escape due to a defect (eg filter defect), the machinery must be switched off immediately and the room has to be aired or leave! Before starting any work on the industrial vacuum cleaner, but particularly before opening covers of live or moving parts, the industrial vacuum cleaner or system must be correctly disconnected from the mains and the drive unit must have stopped The measures specified below may only be withdrawn when the industrial vacuum cleaner is completely reassembled and the maintenance is concluded. The usual safety regulations are, for example, in accordance with VDE 0105: Disconnect from mains Provide a safeguard to prevent unintentional restarting Check that the equipment is not live Cover or shield adjacent live parts. 8.2 Initial fault elimination measures NOTICE All the errors mentioned in the table below may be eliminated by yourself. In case of major problems or other failures please contact the customer service of Ringler immediately.
