While the sensors have an expected life of more than five years in normal use it is recommended that the
analyzer is re-calibrated annually. This is so that long-term drift can be eliminated. Local regulations may
require more frequent re-calibration and users should check with appropriate authorities to ensure compliance
with relevant guidelines.

Periodically clean your instruments case using a damp cloth. DO NOT use abrasive, flammable liquids,
cleaning solvents, or strong detergents as they may damage the finish, impair safety, or affect the reliability
of the structural components.

The in-line water trap should be checked and emptied on a regular basis. Water vapor will condense in the
probe line, which may cause the water trap to fill suddenly if the probe is moved. Care should be taken
at all times.
Carefully un screw the plug from the bottom
of the water-trap 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. Ensure plug is replaced before
performing combustion tests. Note: CO2 reading will
be low if the Water Trap Plug is not in place.

This is a very important part of the analyzer 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 discolored on the inner surface.
Remove water-trap assembly from the analyzer
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 analyzer.
