Activation
-
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 J2912 standard for 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-1234yf is 98% or greater by weight, the green PASS LED. The weight concentrations of R-1234yf, R-134a, R-12, R-22, hydrocarbons and air will be displayed on the digital display.
-
If refrigerant R-1234yf 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-1234yf, R-134a, R-12, R-22 and hydrocarbons will be
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 will sound alerting the user of potential hazards. The weight
concentrations of R-1234yf, R-134a, R-12, R-22 and hydrocarbons will
also be displayed on the digital display.
-
The percentage of air contained in the sample will be
displayed if the R-1234yf 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-1234yf is 98% or greater by weight) and
air concentration levels are 2% or greater by weight, it will prompt 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-1234yf 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 or 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.
Inspection
NOTE:
A coolant leak in the heater hose could follow the
heater core tube to the heater core and appear as a leak in the heater
core...
