10.2 CHANGING THE PARTICLE FILTER
This is a very important part of the analyser and should be changed
regularly. It prevents dust and dirt particles from entering the pump and
sensors that will cause damage. The filter MUST be changed when it
appears discoloured.
Remove water-trap assembly from the analyser as shown above.
Remove the filter and plastic holder from the housing. Discard the filter
element but keep the holder to fit to the new filter. Clean the inside of the
filter housing with a suitable soft cloth. Fit the holder onto the new filter
element and then insert into the housing. Refit the housing onto the
analyser.
