Cleaning and Servicing 8 Cleaning and Servicing 8.1 Maintenance / Visual Inspection Every 6 months, check mains cable for damage (visual inspection) and function of protected earth PE. 8.2 Cleaning (ISG3410-WK and -TWK) The unit must be cleaned regularly. To do this, switch it off at the mains and depressurize (remove the mains plug and also at ISG3410-WK unplug compressed air). The device can be cleaned on the outside using a moist cloth and standard (solvent-free) cleaning agents. The cooling emulsion (Synergy 905 or own products with similar contents) should be changed regularly, depending on the contamination level of tank and cooling emulsion, in order to avoid excessive contamination. Depending on the contamination level, a system cleaner (Techniclean MTC 43 or own plant cooling emulsion with similar contents) should be used between cooling emulsion changes. (Manufacturer's details see 10.7.2 Safety Data Sheet Techniclean MTC 43, page 60) Mix the system cleaner with coolant and leave it in the tank for one day (approx. concentration of 1%) Shrinking can be carried out for one day with the system cleaner. The cleaner should not be left in the tank for longer than one day! Keep the unit clean and clean as necessary! Never use compressed air or cleaning agents! The unit may only be opened or repaired by manufacturer’s service personnel! The manufacturer only recommends the use of Synergy 905 as the emulsion and Techniclean MTC 43 as the cleaner! If this is not possible, only non-flammable, ester-oil-free emulsions and cleaners may be used, and the technical and chemical properties of these must match Synergy 905 and Techniclean MTC 43.
