8. MAINTENANCE
8.1 Emptying and Cleaning the In-line Water Trap
The in-line water trap should be checked and emptied on a regular basis. Water vapour will
condense and gather in the probe line. This may move suddenly to the trap when the probe is
moved. Care should be taken at all times.
Emptying of the water trap is detailed below :-
Carefully remove the end cap from the in-line housing. Dispose of the condensate in a
suitable drain, care must be taken as it could be acidic. If condensate spills onto the skin or
clothing, clean off immediately using fresh water, seek medical advice if problems occur.
8.2 Changing the Particle Filter
This is a very important part of the analyser and should be changed regularly. It prevents dust
and dirty particles entering the pump and sensors and hence causing damage. The filter
MUST be changed when it is discoloured.
Remove the end cap from the in-line filter housing. Carefully remove the paper filter element
and dispose of it. Clean the inside of the filter housing with a suitable soft cloth. Insert a new
filter element onto the spigot in the filter housing and carefully replace the end cap.
