6. WAGELOK B V can tell that especially during the start up of a system the demand for spare part kits is high This is despite all the effort taken to assure a clean system there is usually some debris left in the system which damages the regulator Having spare part kits on site will save time and money as the downtime of the system will be reduced to a minimum whether during start up or normal operation 4 1 Points of attention for maintenance SWAGELOK B V recommends to remove the regulator from the installation 4 2 Required tools for maintenance a vice to fasten the regulator wrench nr 36 wrench nr 17 a pair of tongs for a circlip different pair of tongs to remove the O rings 4 3 Blow off the system pressure Before starting the maintenance on the RS2 make sure there is no pressure left in the system so depressurize the in and outlet side of the system Check carefully 4 4 Points of attention for disassembly SWAGELOK B V recommends to remove the RS2 from the installation before starting with the maintenance In every spare parts kit the cartridge will be supplied as an assembly individual parts cannot be delivered RHPS Series 2 OWAN The adjustment knob is provided with an anti turn out ring Do not force it 4 5 Disassembly Put the RS2 with the flat sides on the bottom into a vice make sure it is secure Turn the adjustment knob counter clockwise until it blocks Remove the spring housing
