For Your Safety:
PLEASE READ THIS MANUAL IN ITS ENTIRETY BEFORE ATTEMPTING
INSTALLATION OR OPERATION! Attempting to operate this tool without fully
understanding its features and functions may result in unsafe conditions.
Analyzer Warnings
o REFRIGERANT BLEND WARNING: Operate this unit with vehicles or
cylinders marked to contain R-1234yf, R-134a or R-12 refrigerant. Cross-
contamination 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 in a system or in
the same container.
o SAMPLE HOSE WARNING: Replace the sample hose AS SOON AS
LIQUID, OIL OR RED SPOTS (DISCOLORATION) BEGIN TO APPEAR
ON THE INSIDE DIAMETER OF THE SAMPLE HOSE OR WHITE FILTER
ELEMENT. Failure to properly maintain and replace the sample hose will
result in severe damage or inaccurate results.
o FLAMMABILITY WARNING: Some vehicles may contain flammable
refrigerants such as hydrocarbons. R-1234yf is considered a flammable
substance. Failure to follow the manual can result in serious injury or
death. Less than 2 grams of refrigerant are vented with each sample. This
analyzer is designed with sealed heat sources and without sparking
components.
o SAMPLE INPUT WARNING: DO NOT attempt to introduce liquid or
samples heavily laden with oil into the Low Side sampling hose
configuration. Damage caused to the instrument due to the use of the
wrong hose configuration on the wrong port will void the warranty!
o BATTERY CHARGING WARNING: When charging the internal battery with
the supplied power supply, the power supply may become warm. If the
power supply becomes warm, unplug the cord immediately! When
charging multiple analyzers, allow the charger to cool between each
battery.
o AIR SENSOR WARNING: The air detection sensor is a chemical fuel cell
sensor that will eventually expire. The user must return the unit to an
approved vendor in order to replace the air detection sensor whenever the
instrument indicates as such. Failure to replace the air detection sensor will
result in non-functionality of the instrument.
o POWER SOURCE WARNING: Connection to power sources greater than
13VDC could cause “out of warranty” damage.
o OPPERATIONAL WARNING: If the equipment is used in a manner not
specified by the manufacturer, the protection by the equipment may be
impaired.

General Cautions
 ALWAYS wear eye and skin protection when working with refrigerants.
Escaping refrigerant vapors will present a freezing danger. Do NOT direct
refrigerant escaping from the sample hose toward exposed skin or toward
the face.
 ALWAYS turn the compressor or automobile engine OFF before connecting
the instrument to an air conditioning system.
ALWAYS inspect the sample hose before each use. Replace the hose if it appears
cracked, frayed, obstructed or fouled with oil.
 DO NOT direct refrigerant vapors venting from hoses towards the skin.
 DO NOT disassemble the instrument. There are no serviceable components
internal to the instrument and disassembly will void the warranty.
 ALWAYS place the analyzer on a flat and sturdy surface.
 To reduce the risk of electrical shock, do NOT disassemble the instrument;
do not use the instrument in wet or damp areas.
 Some systems may contain hydrocarbons or flammable refrigerants. This
analyzer is designed with sealed heat sources and without sparking
components. Ensure adequate ventilation and always take proper
precautions when working with refrigerants.
DO NOT breathe refrigerant and lubricant vapor or mist. Exposure may irritate eyes,
nose, and throat. Use recycling equipment certified to meet the requirements of SAE
J2788, J2843, J3030 or J2851 to remove refrigerant from the A/C system. If accidental
system discharge occurs, immediately ventilate the work area. There must be
adequate ventilation in the vehicle servicing area.
 DO NOT utilize any hose(s) other than those supplied with the instrument.
The use of other hose types will introduce errors into the refrigerant analysis
and instrument calibration.
 ALWAYS verify that the refrigerant, tested from the Low Side, does not
contain or will not emit heavy loads of oil or liquid.
 NEVER admit any sample into the instrument at pressures in excess of 500
psig.
 NEVER obstruct the air intake, sample exhaust or case vent ports of the
instrument during use.
 DO NOT utilize the coupler supplied on the service end of the R-134a or R-
1234yf Sample Hoses for any application other than with the instrument. The
coupler supplied is a modified version that does not contain a check valve
and is not suitable for any other refrigerant application.

WELCOME
Thank you for purchasing the LEGEND IDTM Refrigerant Analyzer.
The Legend ID™ Refrigerant Analyzer is designed for use independently or in conjunction with an
SAE J2843 or J3030 approved A/C Service Machine to determine the purity of gaseous R-134a or R-
1234yf refrigerant. We recommend that all personnel who use this instrument read this manual to
become more familiar with its proper operation.
For further information regarding the application, operation or spare parts, please contact the
Neutronics Inc. Customer Service Department. If you have questions or comments, we would like to
hear from you.

1 INTRODUCTION AND OVERVIEW
General
Contamination of refrigerants either in storage cylinders or vehicle air conditioning systems 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 Neutronics Legend ID™ Refrigerant Analyzer will provide a fast, easy and accurate means to
determine refrigerant purity in refrigerant storage cylinders or directly in vehicle air conditioning
systems. The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weight
concentration of R-1234yf or R-134a refrigerant. Acceptable refrigerant purity as it relates to this
instrument, has been defined by the SAE as a refrigerant mixture that contains 98.0%, or greater of
R-1234yf or R-134a, by weight.
The instrument is supplied complete with an R-1234yf sample hose, an R-134a sample hose (R-12
coupler sold separately), a 100- 240 VAC power transformer, built in Lithium 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. 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 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.
Required SAE Statement (SAE J2912): "If the refrigerant being tested is identified as
contaminated (i.e., less than 98% pure R-1234yf or HFC-134a), any visual percentages displayed
of HFC-134a (R-134a) and/or HFO-1234yf (R-1234yf), outside the design certified value is
informational and may not be accurate"

Base Unit
The Legend ID™ base unit houses the Full Color Graphic LCD, Infrared Bench, Electrical
Connections, and Rechargeable Battery. These components require no maintenance, therefore
there are no serviceable components internal to the instrument, and disassembly will void
the warranty.
Legend R-1234yf Sample Hose
The 6.5-foot (2 meter) R-1234yf Sample Hose is constructed of polyurethane ether. The hose is
provided with an instrument inlet port mating connector on one end and a brass flow restrictor on
the other end. The brass flow restrictor screws into the R-1234yf Low Side Coupler. The sample
hose is considered a consumable maintenance part. A spare R-1234yf Sample Hose is also
