Maintenance Operation on the Refrigerating Circuit
WARNING! Unauthorized interference!
Tampering the safety and security devices is not
permissible. Only skilled workers of the manufacturer are authorized to work on the cooling
system.
NOTICE! Environment protection!
Do not dispose this fluid in the environment. It has to be
disposed according to legal regulations.
Visual inspection of the refrigerating circuit for signs of oil and refrigerant leakage.
This sample gas cooler comes ready to operate and filled with R134a type refrigerant fluid. In
case of refrigerant leak contact directly the manufacturer of the sample gas cooler. The room is
to be aired before any intervention. Data of the use refrigerant liquids:

Maintenance Operation on the Condenser Unit
The degree of contamination of the condenser can adversely affect the performance of the
device. Clean the air-cooled condensers using a soft brush or do a very careful air cleaning..
Additional cleaning may be required apart from maintenance intervals depending on the degree
of contamination and operating conditions.
Maintenance Operation on the Heat Exchanger Unit
Inspect the heat exchange unit and its insulation visually for damage or condensate formation.
The formation of condensate indicates damaged insulation and refrigeration loss. The
consequences can be increased energy consumption and reduced performance of the device.
Maintenance Operation on the condensate pumps (optional)
When the condensate pump is operated for a long time, the pump hose eventually wears out.
Condensate and sample gas may leak from the pump hose. There is also the risk of external air
being sucked from porous points. This may lead to wrong measurement results. In this case the
pump hose must be replaced immediately. We recommend replacement of the pump hose after
every 3 months as a precautionary measure. When processing the replacement please check
the condition of roller carriers and conveying belts, too.
