8. The instrument presents the results of the analysis as outlined below:
PASS R-134a: If the instrument has detected 98% by weight or greater concentration
of R-134a, the green PASS LED illuminates and the weight concentrations of R-12, R-
134a, R-22, hydrocarbons, and air are displayed. The display then prompts the user to
press “A” to print, or press “B” to continue. See Step 9.
PASS R-12: If the instrument has detected 98% by weight or greater concentration of
R-12, the green PASS LED illuminates and the weight concentrations of R-12, R-134a,
R-22, hydrocarbons, and air are displayed. The display then prompts the user to press
“A” to print, or press “B” to continue. See Step 9.
Refrigerant FAIL: If the weight concentration of either R-12 or R-134a is not at least
98%, the instrument will sound the alarm horn five times. The red FAIL LED illumi-
nates and the weight percentages of R-12, R-134a, R-22, and hydrocarbons are dis-
played. Note that the instrument does not permit purging procedures on contaminated
mixtures. The display prompts you to press “A” to print, or press “B” to exit.
Tech Tip: We suggest retesting a refrigerant source whenever a Refrigerant FAIL
occurs to provide verification of initial results.
Hydrocarbon Alarm: If hydrocarbon concentrations are sensed to be 2% by weight
or greater, the instrument sounds the alarm horn 30 times, illuminates the red FAIL
LED, displays HYDROCARBONS HIGH, and displays the weight concentrations of
R-12, R-134a, R-22, and hydrocarbons. The display then prompts the user to press “A”
to print, or press “B” to exit.
WARNING
The occurrence of the hydrocarbon alarm alerts you to the presence of
potentially flammable refrigerant mixtures. YOU BEAR FULL RESPONSIBILITY for
the removal of the potentially hazardous mixture from the instrument and any
other attached equipment.
