Use a transparent container to collect the content inside the separator. Check its color, seal it well
and return it to the factory for inspection.
Note:
If the compressor is damaged and needs to be replaced, the gas-liquid separator should also be
replaced, whether or not there are impurities in the separator or other abnormal conditions.
Confirm which parts of the system should be replaced. Make sure the pipe mouths of the damaged
parts or components are sealed by adhesive tape as soon as they are detached. Keep them in the original
condition for future analysis.
Step 7: Clear the pipeline
After confirming which parts of the system should be replaced, check the pipeline of the system. Blow
through the main pipeline with nitrogen. After clearing the pipeline, if the components are not replaced
immediately, seal the pipeline with adhesive tape to prevent the system from being contaminated by water
and impurities in the air.
Step 8: Replace the compressor
For the removal of compressor, please refer to the section: Removal of Major Components.
Step 9: Check/Replace the gas-liquid separator
Note:
If a compressor is damaged and needs to be replaced, its gas-liquid separator should also be
replaced. This is to avoid the abnormal condition of the separator from affecting the safe and reliable
operation of the system.
