Cleaning and Disinfecting Cleaning and Disinfecting The MOBILETT shall be disconnected from the mains and switched off before it is cleaned or disinfected. Cleaning Do not use any abrasive detergents (because of material intolerance) or cleaning agents containing solvents (e.g. cleaning solutions, alcohol, stain remover). Caution The cleaning fluid has penetrated into the equipment! The MOBILETT is damaged...
Cleaning and Disinfecting Disinfection For surface disinfection, we recommend the use of isopropyl alcohol. Disinfec- tants based on substituted phenols and compounds splitting of chlorine are caustic and therefore, cannot be generally recommended. As a general rule, no disinfectants sprays must be used, since the spray mist may penetrate into the equipment which means the safety of the equipment can no longer be assured (damage to electronic components, formation of flammable air solvent vapour mixtures).
