NOTE:
Use Refrigerant Identification Equipment to identify
gas samples taken directly from the refrigeration system or storage
containers prior to recovering or charging the refrigerant system.
NOTE:
Use Refrigerant Identification Equipment that
conforms to SAE J1771 for R-134a or SAE J2912 standard identifies R-134a
and R-1234yf.
Follow the instructions included with Refrigerant Identification Equipment to obtain the sample for testing.
-
198‐RI2012yfp A/C Refrigerant Analyzer for use with R134a and R1234yf vehicles
Use the General Equipment: Refrigerant Identification Equipment
-
NOTE:
The refrigerant identifier displays one of the following:
-
If the purity level of R-134a is 98% or greater by weight, the green
PASS LED . The weight concentrations of R-134a, R-12, R-22, hydrocarbons
and air will be displayed on the digital display.
-
If refrigerant R-134a does not meet the 98% purity level, the red FAIL LED
and an alarm sounds alerting the user of potential hazards. The weight
concentrations of R-134a, R-12, R-22 and hydrocarbons are displayed on
the digital display.
-
If hydrocarbon concentrations are 2% or greater by weight, the red FAIL LED
, "Hydrocarbon High" will be displayed on the digital display, and an
alarm sounds alerting the user of potential hazards. The weight
concentrations of R-134a, R-12, R-22 and hydrocarbons also are displayed
on the digital display.
-
The percentage of air contained in the sample is
displayed if the R-134a content is 98% or greater. The refrigerant
identifier eliminates the effect of air when determining the refrigerant
sample content because air is not considered a contaminant, although
air can affect A/C system
performance. When the refrigerant identifier has determined that a
refrigerant source is pure (R-134a is 98% or greater by weight) and air
concentration levels are 2% or greater by weight, it prompts the user if
an air purge is desired.
-
If contaminated refrigerant is detected, repeat the
refrigerant identification test to verify the refrigerant is indeed
contaminated.
-
NOTICE:
If contaminated refrigerant is detected, DO NOT
recover the refrigerant into R-134a recovery/recycling equipment.
Recovery of contaminated refrigerant contaminates the recovered
refrigerant supply and may damage the recovery/recycling equipment.
NOTE:
Install a new suction accumulator, receiver drier or receiver drier element as directed by the A/C system flushing procedure.
Recover the contaminated refrigerant using suitable
recovery-only equipment designed for capturing and storing contaminated
refrigerant only.
-
Determine and correct the cause of the customer's initial concern.
-
Refer to Air Conditioning (A/C) System Flushing procedure in Group 412.
-
Dispose of the contaminated refrigerant in accordance with all federal, state and local regulations.
