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
oREFRIGERANT BLEND WARNING: This refrigerant analyzer is approved
for specific refrigerant testing and should not be used with substances
outside the scope of the device. 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.
oSAMPLE 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.
oFLAMMABILITY WARNING: Some systems may contain flammable
refrigerants such as hydrocarbons. 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.
oSAMPLE INPUT WARNING: DO NOT attempt to introduce liquid or
samples heavily laden with oil into the vapor 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!
oBATTERY 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.
oAIR 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.
oPOWER SOURCE WARNING: Connection to power sources greater than
13VDC could cause “out of warranty” damage.
oOPPERATIONAL 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 power source OFF before connecting the
instrument to an HVAC/R 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. If accidental system discharge occurs,
immediately ventilate the work area. There must be adequate ventilation
when operating this device.
•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 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 Sample Hoses
for any application other than with this instrument. The coupler supplied is a
modified version that does not contain a check valve and is not suitable for
any other refrigerant application.

1INTRODUCTION 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 Bacharach 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.

1.2 Legend SeriesTM HFC Components
Legend SeriesTM HFC Base Unit
The Legend Series™HFC unit houses the Full Color Graphic LCD, Infrared Bench, Electrical
Connections, and Rechargeable Battery. The device is factory calibrated and completes an air
calibration to confirm infrared signals before testing. These components require no maintenance,
therefore there are no serviceable components internal to the instrument, and disassembly
will void the warranty.
Legend Vapor Sample Hose
The 6.5-foot (2 meter) 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 ¼” Flare coupler. The sample hose is considered a
consumable maintenance part. A spare Sample Hose is also provided. Maximum pressure is 500
psig (35 Bar).
