Replacing the Brass Sample Hose Restrictor

In either Vapor Sampling or Liquid Sampling mode always inspect the inside diameter of the
tube for signs of oil build up, dirt, obstructions, kinks, cuts, fraying, or any other signs of wear
before use. Oil contamination cannot be cleaned out of sample hoses due to the density of
the brass oil restrictor. If oil is visible in the hose assembly, replace the Brass Sample Hose
Restrictor Assembly with P/N 6-01-6001-26-0.
NOTE:
The analyzer will indicate "Non-Condensable" or "Unknown Refrigerant" if the
analyzer does not receive a good sample due to obstructed flow or lack of flow
(approximately less than 30 psig or 2 Bar). If this occurs the Brass Sample Hose Restrictor
may need to be replaced.
To replace the Restrictor Assembly, follow the instructions below:

Disconnect the sample hose from the Analyzer
Remove the brass restrictor (with hose attached) from the coupler and
discard. Be sure to use a backing wrench as not to damage the
coupler.
Check for signs of oil and debris in the coupler.
Using "CRC Brakleen" or similar cleaner which ONLY contains,
Tetrachloroethylene and carbon dioxide, follow safety instructions on
the can and spray all parts of the coupler with the cleaner to remove
the oil. DO NOT soak the parts for more than 60 seconds.
Allow coupler parts to dry. Check coupler parts for oil once again.
Failure to clean the oil out of the coupler will result in premature
clogging of the new filter.
Install the Brass Sample Hose Restrictor, part number 6-01-6001-26-0,
into the coupler and lightly tighten, usually finger tight is sufficient.
