Locate one of the EC155 intake filters p n 26072 in the mesh pocket of the EC100 enclosure Remove the old filter by pulling on the small santoprene tab on the edge of the filter see Figure 9 1 Once removed make sure the underlying aluminium disk and intake hole are free from debris Place a new filter on the aluminium disk Press along the santoprene edge to make sure it is well seated NOTEThe standard intake filter has a sintered disk with 20 micron pore size For dusty sites an intake filter with 40 micron pores may be ordered p n 28698 which will increase the lifetime of the filter Ideally the appropriate pore size will result in the filter needing replacement at the same time the windows need cleaning see Section 9 3 For extremely dusty conditions lowering the flow rate through the analyzer will further increase the lifetime of the filter although this will also result in a decrease in frequency response Santoprene Tab a Figure 9 1 The underside of the optional heated intake 9 3 Cleaning Analyzer Windows The windows of the analyzer should be cleaned 1f the signal strength of CO or H2O drops below 80 of the original value These values may be monitored in 25 EC155 CO and H20 Closed Path Gas Analyzer and EC100 Electronics with Optional CSAT3A 3D Sonic Anemometer 26 the output data or they can be viewed with ECMon To clean the windows follow these steps a b Thumbscrew

11. Closed Path Gas Analyzer and EC100 Electronics with Optional CSAT3A 3D Sonic Anemometer If the EC155 is configured without the optional heated intake assembly there is tubing connecting the sample inlet fitting to the sample cell that will drop the pressure approximately 4 kPa at 7 LPM 6 2 3 Filtration The EC155 will not be damaged by use without an inlet filter although a coarse screen up to 1 mm hole size is suggested to keep large debris out Over time particulates will collect on the optical windows reducing the signal levels until the windows must be cleaned see Section 9 3 Cleaning Analyzer Windows Using a filter on the inlet will increase the time before the windows must be cleaned A finer pore size will keep the windows clean longer but will need to be replaced more frequently The optional heated intake assembly includes a 20 micron filter element which gives a compromise between filter replacement and window cleaning 6 2 4 Plumbing Connections There are three connections to the EC155 sample cell the sample inlet zero and span inlet and pump outlet as illustrated in Figure 6 4 In the normal mode a vacuum pump pulls an air sample from the sample inlet through the sample cell In zero and span mode the pump is turned off and a zero and span gas is pushed backwards through the sample cell exhausted out through the sample inlet Analyzer Head Cable Pump Zero Span Sample Sample Cell Cable Figure 6 4
