48Maintenance6.3 Routine maintenance scheduleThe maintenance schedule is given for standard applications.Deviant applications may cause different maintenance intervals.Table 6 Routine maintenance scheduleDescription3 months(Customertask)6 months(Servicetask)12 months(Servicetask)24 months(Servicetask)Visual check analytical compartment, manual cleaning ifnecessary. X1 XCheck filter pads, clean/ replace if necessary, particularly onfan side. X1 XCheck reagents, replace if necessary. X1 XCheck cleaning solution, replace if necessary. X1 XCheck maintenance counters. X1 XCheck standard solutions, replace if necessary. X1 XVisual check of electrode, replace membrane cap andelectrolyte if necessary X1 XCheck system for air impermeability. XFunction check of both fans. XFunction check heating for analyser enclosure. XGeneral function check. XRead out and analyse event log. Read out and check data logif necessary. XCheck electrode (slope with intact membrane cap: –55mV to–67mV), check every 6 months after 12 months of use. (X) 2 XReplace pump head for air pump. XCheck magnetic stir bar, replace if necessary. XReplace reagent pump. XCheck cleaning pump and replace if necessary (check every6 months after 12 months of use) (X) 2 XCheck stirring motor, replace if necessary. X1 Recommended maintenance interval, especially for reagents. The actual reagent and electrolyte (AMTAX sc) exchangeintervals depend on configuration.2 Maintenance cycles are given for standard applications. Deviant applications may cause different maintenance intervals.
