CHANGING THE FILTER
Disable the power supply to the Instrument and open the front cover. Remove the four corner
screws from the front panel and carefully ease the front panel away from the Instrument case.
The panel is attached to the main circuit board by some wires but it can be temporarily 'parked' in
the uppermost slots on the left and right sides of the case. Locate the plastic filter unit fitted in
the Gas Inlet Pipe. Carefully remove the plastic tubing from the ends of the and insert the new
filter in the piping. Replace the front panel, ensuring that the wires to the front panel are not
trapped between the panel and the case. The Instrument may now have its power supply restored
and after initial warm-up will be ready for operation.
Replacement Filters are available from Scottish Anglo E.P. Ltd. and should be ordered as Part
Number 1000-1401
A full Calibration procedure, as detailed in Section 5 should now be carried out.
NOTE : If the Instrument is being used in a particularly dusty atmosphere, the filter may
require changing more frequently.
