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
illuminates and the weight percentages of R-12, R-134a, R-22, and hydrocarbons are
displayed. Note 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.
