1 INTRODUCTION AND OVERVIEW
General
Contamination of refrigerants either in storage cylinders or HVAC/R system can lead to component
corrosion, elevated head pressures and system failures when utilized by unsuspecting technicians.
The ability of the technician to determine refrigerant type and purity is severely hampered by the
presence of air when attempting to utilize temperature-pressure relations. The development of
various substitute refrigerants further complicates the ability of a technician to identify refrigerant
purity based upon temperature-pressure relationships.
The Legend Series™ HFC Refrigerant Analyzer will provide a fast, easy and accurate means to
determine refrigerant purity in refrigerant storage cylinders or directly in an HVAC/R system.
The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weight
concentration of many common refrigerants.
The instrument is supplied complete with a ¼” Flare Vapor Sampling Hose, ¼” Flare Liquid Sample
Hose, Hose Extensions for ease of connection, a High-Pressure Liquid Sample Trap Assembly, a
100-240 VAC power transformer, built in rechargeable Lithium-Ion battery, thermal printer, and all
required plumbing housed within a rugged, portable, storage case.
Sample gas is admitted into the instrument through the supplied sample hose and presented to the
sensing device. The instrument provides the user with a digital display of refrigerant purity or
identified refrigerant. The instrument only considers the weights of the refrigerant and contaminates
in the total mixture. Air is measured, and displayed, separately. Other contents such as refrigerant
oil, moisture and dye are not considered contaminants.
The instrument interfaces with the user via a full color graphic LCD, audio indications and soft key
command buttons. Alarm indications are provided to alert of instrument fault conditions or
contaminated refrigerant presence.

¼” Flare Coupler
The ¼” Flare coupler is designed for easy connection to a cylinder or HVAC/R system. The coupler
can be used for vapor or liquid sampling. Liquid sampling will require the use of the liquid sample
hose and liquid sample syringe.
Sample Hose Extensions
The sample hose extensions allow the user to easily connect and disconnect the hose assembly to
the analyzer. The extension is connected directly to the analyzer and the sample hose connects to
the male feral on the opposite end.
Liquid Sample Trap
The liquid sample trap is designed as a barrier to oil or liquid refrigerant entering the analyzer.
During liquid sampling, the syringe will collect oil which may be present in the liquid sample and act
as the catalyst for refrigerant to change phases from liquid to vapor. Liquid sampling will provide a
more accurate analysis of multicomponent refrigerants.

TIP: A refrigerant source with a pressure <30 psig (2 Bar) may require additional flow time to
generate an accurate result. Low pressure samples will take more time to fill the sample bench
and require this additional flow time before the user presses ‘Test.’
2.4 Testing the Refrigerant
Figure 8
Figure 9
Figure 10
Figure 7
After the air calibration is complete, the instrument is ready for to begin the refrigerant
analysis. The analyzer will direct you to connect the hose to a refrigerant source as shown in
(Figure 7). Open the refrigerant source valve, if equipped, and allow the refrigerant to flow
for a few seconds. Next press the ‘Test’ button to begin the test. The Testing screen shown
in (Figure 8) will display.
2.5 Viewing the Test Results
Upon completion of analysis, the Legend Series™ HFC will display (Figure 9). Close the
refrigerant source valve if equipped, and then disconnect the coupler from the refrigerant
source. Select ‘Results,’ which will display the test results (Figure 10). The percentage
displayed for each refrigerant indicates the total purity weight of that refrigerant, equaling
100%, with air measured independently. Pressing ‘Print’ will print the test results. Pressing
‘Print Prior 5 Results’ will print the last 5 tests completed.

main screen (Figure 11). When you are ready to power down the device press the power
button and the powering down screen will appear (Figure 11a).
2.6 Understanding Test Results
The Legend Series™ HFC is designed to analyze or identify a wide array of refrigerants.
Before sampling a gas, you should select the refrigerant you anticipate testing to accurately
align the calibration (Figure 12). If the wrong base refrigerant is selected the analyzer will
still provide accurate single component refrigerant outputs but may not confirm the
refrigerant matches the refrigerant selected (Figure 13).
The refrigerant analyzer is designed to provide visual cues after analysis is complete. There
are six possible result screens that may display. After an analysis, a user may find the
refrigerant is as EXPECTED, IMBALANCED, CONTAMINATED, DILUTED, an IDENTIFIED
refrigerant, or UNKNOWN. Explanation of each possible result is defined below.

Manual File:
069706 Rev. A
Page 2-19
Expected Refrigerant:
Figure 14
Figure 15
Refrigerant analyzed and found to be within an acceptable composition range of the selected
gas will define the results as that refrigerant and display a green screen (Figure 14). In this
example, R-410A is confirmed with some slight composition shift. The R-410A is still within
composition specification of AHRI Standard 700 which qualifies it as R-410A.
Imbalanced Refrigerant:
Refrigerant analyzed and found to have the required components but outside the AHRI
Standard 700 acceptable range will display as Imbalanced with a yellow screen (Figure 15).
In this example, Imbalanced R-410A is confirmed with composition shift. The R-410A has the
correct components but is too far outside the acceptable range to be considered ideal.
Contaminated Refrigerant:
Refrigerant analyzed and found to be contaminated has the expected base components, but
some other refrigerant(s) is present diluting the entire sample. This refrigerant would have a
red screen to indicate it is unacceptable and should not be recovered with pure gas or
reused (Figure 16). In this example, Imbalanced R-410A is contaminated with R-22.

Note: The channel data is representative of the IR signal detected. It is not representative of
any specific refrigerant, is not measured as a % by weight and only indicates an optical response.
Channel data should be used as a reference to help improve accuracy of Identified Refrigerants.
Diluted Refrigerant:
Figure 18
Figure 17
Figure 16
Refrigerant analyzed and found to be diluted will have the expected base components with
any level of Air present in the sample. This refrigerant would have a yellow screen to indicate
the Air has contaminated the sample (Figure 17). Air can be removed from refrigerant but
can be harmful if present inside a system. Air left in a system can alter P/T curves, lead to
moisture accumulation and acid buildup. Both will cause a system to work inefficiently and
lead to possible system failure. In this example, Diluted R-410A is contaminated with Air.
Identified Refrigerant:
Refrigerant analyzed and found to be an identified gas will not display composition of the
refrigerant. Instead, the analyzer confirms the refrigerant matches the expected identified
gas with a green screen and provides channel data to reference as a “fingerprint” model of
that gas (Figure 18). In this example, R-1234yf is Identified as R-1234yf. The channel output
provides a “fingerprint” of this gas. This channel data can be documented and used for future
cross reference to confirm the quality of the identified refrigerant.

Page 2-21
Unknown Refrigerant:
Figure 19
Refrigerant analyzed and found to be an Unknown gas is a gas that does not match any of
the refrigerants directly measured by the device. A yellow screen will appear to indicate
caution as the gas is unknown (Figure 19). If you believe the sampled refrigerant should be
measured by the device restart the analysis and confirm you select the appropriate
refrigerant before calibration. Unknown refrigerant should be handled with care as there is no
certainty to what refrigerant is present.
If an error message appears at all during or after analysis. Refer to section
and Troubleshooting.

3 MAINTENANCE & TROUBLESHOOTING
3.1 Replacing the Sample Hose Assembly.
In the event the analyzer displays an Error #3 or Error #5 this may be an indication the
sample hose needs replacing. This will occur when the integrated flow restrictor becomes
clogged with oil, debris, or sealant. It can also occur if there is inadequate flow of refrigerant
in a cylinder or refrigerant source. Replacement hoses for both the vapor and liquid sample
hose are provided in the kit. Additional replacements are listed on the spare parts list in
section
4 Appendices.
To replace the Sample Hose Assembly, follow the instructions below:
1) Disconnect the sample hose from the refrigerant source and Analyzer
2) Remove the brass restrictor end (with hose attached) from the coupler
and discard. Be sure to use a backing wrench as not to damage the
coupler.
3) Check for signs of oil and debris in the coupler.
4) If oil or debris is present, use a cleaner which ONLY contains,
Tetrachloroethylene and carbon dioxide, follow safety instructions on
the can and spray all parts of the coupler with the cleaner to remove
any oil. DO NOT soak the part for more than 60 seconds.
3.2 Information Screens
An “Information” icon or ‘Help’ indication will appear at various points throughout the
testing process. This button will provide additional information or tips about the command
screens to help complete your analysis.
5) Allow coupler to dry. Check coupler for oil once again. Failure to clean
the oil out of the coupler will result in premature obstruction of the new
sample hose.
6) Install the brass end of the new sample hose assembly into the
coupler and lightly tighten, usually finger tight is sufficient.
