Safety Precautions • • WARNING : To prevent personal injury: Allow only certified personnel to operate the Identifier. Study, understand, and follow all warnings in this manual before operating this unit. If the operator cannot read these instructions, operating instructions and safety precautions must be read and discussed in the operator’s native language.
Safety Precautions cont’d • • • • • • 2 Operate this unit with R-134a refrigerant only. Crosscontamination with other refrigerant types causes severe damage to the A/C system, to service tools, and equipment. Do NOT attempt to adapt the unit for another refrigerant. Do NOT mix refrigerant types through a system or in the same container. Do not breathe refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, and throat.
Safety Precautions cont’d CAUTION: To prevent equipment damage, • • • • • • • • • • • Brass Filter: This instrument is equipped with a brass filter located at the outlet of the R134a coupler. This filter significantly reduces the possibility of oil contamination in the unit. Replace this filter when oil is detected in the hose near the coupler, or when the unit indicates “Excess Air / Fail”. Failure to replace the filter when so indicated may result in “out-of-warranty” damage to the instrument.
Description Contamination of refrigerant in air conditioning systems can lead to component corrosion or destruction, elevated system head pressure, and system failures when used by unsuspecting technicians. Determining refrigerant type and purity is severely hampered by the presence of air when attempting to use pressure-temperature relationships. The 16009 DiscovR R134a Refrigerant Identifier provides a fast, easy, and accurate means to determine purity in R134a refrigeration systems.
Operating Instructions Understanding the LED Indicators • A solid LED light indicates the unit is busy. • A flashing LED light indicates the unit is waiting for the operator. Operation 1. Remove the DiscovR Identifier from the box and expose the unit to fresh air. 2. Verify the vehicle ignition is turned OFF. Connect the power cable clips (red to positive; black to a metal ground) to the vehicle’s 12-volt battery. 3. Connect the power cable to the Identifier.
Operating Instructions cont’d 8. After analyzing the refrigerant, a PASS or FAIL LED flashes: a. A flashing PASS LED indicates the refrigerant is 95% pure or better. b. A flashing FAIL LED indicates the refrigerant is less than 95% pure. c. The EXCESS AIR LED will light with either a PASS or FAIL LED if the unit has detected a large amount of air in the refrigerant. Note: The indication of excess air may be the result of oil or other contaminants trapped in the brass filter. 9.
Fault Codes & Troubleshooting Fault Codes If the DiscovR unit displays a fault light, the code is determined by counting the number of times the fault light flashes. Code 1 Code 3 Code 4 Code 5 = = = = Calibration unstable Calibration error Temperature over the range Calibration compensation error If any of these codes display, disconnect the unit from its power source and bring it to a room temperature (60°– 80° F) place. Check the vehicle battery voltage, and confirm it is within specified range.
