3.1 Replacing the Sample Hose Assembly.
In the event the analyzer displays an Error #3 or Error #5 this may be an indication the
sample hose needs replacing. This will occur when the integrated flow restrictor becomes
clogged with oil, debris or sealant. It can also occur if there is inadequate flow, less than 30
psig (2 Bar) refrigerant in the vehicle or cylinder. Replacement hoses for both the R-134a and
R-1234yf couplers are provided in the kit. Additional replacements are listed on the spare
parts list in section
4
Appendices
.
To replace the Sample Hose Assembly, follow the instructions below:
1)
Disconnect the sample hose from the refrigerant source and Analyzer
2)
Remove the brass restrictor end (with hose attached) from the coupler
and discard. Be sure to use a backing wrench as not to damage the
coupler.
3)
Check for signs of oil and debris in the coupler.
4)
Use a 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 any oil. DO NOT soak the part for
more than 60 seconds.
5)
Allow coupler to dry. Check coupler for oil once again. Failure to clean
the oil out of the coupler will result in premature obstruction of the new
sample hose.
6)
Install the brass end of the new sample hose assembly into the
coupler and lightly tighten, usually finger tight is sufficient.
