Refrigerant R1234YF Analysis
It is necessary for the operation of the A/C system that the refrigerant used has a certain purity.
Faulty gas analysis is possible due to air in the refrigerant hose or not following the procedure of the gas analysis according to the Service Information.
Pay exact attention to the gas analyzer / A/C Service Station Service Information.
Evacuate the refrigerant hoses from the A/C Service Station before connecting the service couplings to the refrigerant circuit / on the gas cylinder with refrigerant R1234yf. Refer to the gas analyzer/ A/C Service Station Service Information. Refer to REFRIGERANT GAS ANALYSIS, PERFORMING .
Contamination with other refrigerants or gases can case damage and lead to failure of the A/C system and the A/C Service Station.
Contaminated refrigerant must be analyzed as a gas of an unknown composition according to the legal requirements and then recycled (or disposed). Refer to REFRIGERANT GAS ANALYSIS, PERFORMING .
Return the contaminated refrigerant R1234yf for analysis to the refrigerant supplier. If because of the damage on the refrigerant circuit, which has already occurred or is expected it must be known with which foreign substance the refrigerant is contaminated, perform the corresponding claim to request the analysis findings. Refer to RETURNING CONTAMINATED REFRIGERANT R1234YF FOR ANALYSIS, PROCESSING, OR DISPOSAL .
The following values apply for a gas analysis of clean refrigerant R1234yf:
- The extracted refrigerant gas is made up of a minimum of 95 % refrigerant R1234yf.
- The portion of foreign gases (oxygen, nitrogen, steam, and other refrigerants) is smaller than 5 %.
So that fluids components (for example drops of refrigerant oil) in the extracted refrigerant gas does not lead to a faulty result of the gas analysis, a separator (filter) is installed in the gas analyzer which separates the fluid drops. Replace the separator according to the specification of the gas analyzer for example the Service Information belonging to the A/C Service Station. Refer to the appropriate Gas Analyzer Service Informatoin or the appropriate Service Information A/C Service Station.
