Instruction Manual MM850402 ed. 0610 MAINTENANCEThe 3000-4000 series analyzer has been developed and manufactured using high quality components. A correct,systematic maintenance will prevent damage and will increase the life of the instrument, giving excellent results.Any conditions that require extraordinary maintenance interventions are promptly displayed, either clearly or withan information code.10.1 Water trapAlways keep in vertical position the water trap to avoid that the water condensation inside the trap could flow tothe measuring sensors. For the same reason remember to periodically empty the trap and always at the end ofthe measurement. To empty the expansion vase remove the cap (code EE650081) and gently shake it. Pleasebe sure to reinsert the cap before the measurements.Just after the trap you can find a replaceable low porosity line filter (code EE650074). It hold le solid particles ofthe gas. We recommend you to replace this filter is it's dirty. To replace the paper filter open the trap gentlyrotating the two trap parts.Line Filter cat.EE650074Cap cat.EE650081!! ATTENTION !!DON'T MAKE MEASUREMENTS WITHOUT THE TRAP CAP. IF THE CAP IS NOT MOUNTED ON THE TRAP YOU WILL HAVE ANAMBIENT AIR INPUT INTO THE PNEUMATIC CIRCUIT THAT WILL GIVE YOU WRONG MEASUREMENT VALUES,CONTROL AND EMPTY, AT EACH MEASUREMENT, THE WATER IN THE TRAP IF PRESENT. PUT THE TRAP IN HIS CASE AFTEREMPTYING THE CONDENSATION FROM BOTH THE TUBE AND THE EXPANSION VASE ONLY.TO OPEN THE TRAP GENTLY ROTATE THE TWO PARTS. DON'T PULL. DON'T TWIST.REPLACE THE FILTER IF IT'S DIRTY OR HUMID.
