[. . . ] Risk of injury due to interior cleaner toppling over at low submerge depth. Risk of injury by toppling container therefore use extra support for container and interior cleaner. Danger of injury by interior cleaner sliding off; therefore tighten interior cleaner with clamping ring. Function – The interior cleaner consists of a drive unit, a support pipe and the cleaning head. [. . . ] € Zone 21 Zone 21 is an area where (during normal operation) dangerous explosionrisk atmosphere is present as a cloud of flammable dust in the air from time to time. € Zone 22 Zone 22 is an area where (during normal operation) dangerous explosionrisk atmosphere as a cloud of flammable dust is not normally present and if present, only for a short time. 7 8 9 10 11 12 13 14 15 16 The nominal pressure of the pump must not exceed 5 MPa when operating with solvents. The compressed air motor must only be operated once the interior cleaner has been filled with cleaning liquid. The operating temperature of the cleaning liquid water with cleaning agents must not must not exceed 95 °C. The operating temperature of the cleaning liquid solvents, brines and acids must not must not exceed 20 °C. The interior cleaner must be checked for flawless condition and smooth function after a certain operating time has passed (incl. The interior cleaner must only be used with cleaning liquids and in such media, whose affect on the materials is not damaging. Cleaning liquids that contain flammable solvent particles, must comply with the ignition groups IIA and IIB. The interior cleaner must not be constantly located in Zone 0, but only during the actual container cleaning. The operating guidelines as per BetrSichV as well as other national guidelines must be adhered to. Take into consideration, that the mixture of the container/ interior cleaner brought into the container is not resistant to breakdown from flames. hoses must be conductive (electrostatically) (resistance R < 1000 Ohm). Only cleaning agents with a conductivity G > 1000 pS/m may be used. Special conditions in the Ex area 1 2 3 4 The interior cleaner must only be used in Zone 0 if the containers are at least 1 m in diameter with the usual container height or do not exceed a comparable container size. The mass content of non-diluted solid substances in the cleaning liquid must not exceed 1%. The pump for the cleaning liquid must only be operated while it is filled with fluid.
