For Your Safety:
PLEASE READ THIS MANUAL IN ITS ENTIRETY BEFORE ATTEMPTING
INSTALLATION OR OPERATION! Attempting to operate the Mini ID
without fully understanding its features and functions may result in
unsafe conditions.
Always use protective eye wear and observe proper safety procedures when
working with pressurized gases.
Identifier Warnings
Sample Filter Warning: The Mini ID contains a unique filter designed to sig-
nificantly reduce the probability of oil contamination. Replace the brass oil
filter of the instrument AS SOON AS OIL IS DETECTED IN THE SAMPLE HOSE.
Failure to properly maintain and replace the oil filter may result in severe
damage.
Sample Input Warning: The instrument requires connection of the supplied
sample hose to the LOW SIDE OR VAPOUR port of refrigerant storage cylin-
ders or vehicle air conditioning systems. DO NOT attempt to introduce liquid
or samples heavily laden with oil into the instrument. DO NOT connect the
sample hose to the HIGH SIDE or LIQUID port! Liquid or oil laden samples
may cause severe damage to the instrument that will not be covered under
warranty repairs.
General Cautions
• Always inspect the sample hose before each use. Replace the hose if it
appears cracked, frayed, obstructed or fouled with oil.
• Always turn the compressor or automobile engine off before connecting
the instrument to an air conditioning system.

• Always wear eye and skin protection when working with refrigerants. Es-
caping refrigerant vapours will present a freezing danger.
• To reduce the risk of electrical shock, do not disassemble the instru-
ment; do not use the instrument in wet or damp areas.
• DO NOT direct refrigerant vapours venting from hoses towards the skin.
• DO NOT disassemble the instrument. There are no serviceable compo-
nents internal to the instrument and disassembly will void the warranty.
• Always place the Identifier on a flat and sturdy surface.
• DO NOT utilize any other hose other than those supplied with the instru-
ment. The use of other hose types will introduce errors into the refriger-
ant analysis and instrument calibration.
• Always verify that the refrigerant to be tested 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
300 psig.
• DO NOT utilize the coupler supplied on the service end of the R134a
Sample Hose 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.
• NEVER obstruct the air intake, sample exhaust or case vent ports of the
instrument during use.
• WARNING – This Identifier must not be operated in flammable atmos-
pheres.
• CAUTION – Should be operated by certified personnel.
• Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may
irritate eyes, nose and throat. To remove HFC-134a from the A/C system,
use service equipment certified to meet the requirements of SAE J2788.
Additional health and safety information may be obtained from refrigerant
and lubricant manufacturers.
• CAUTION – Do not pressure test or leak test HFC-134a service equipment
and/or vehicle air conditioning systems with compressed air. Some mix-
tures of air and HFC-134a have been shown to be combustible at elevated
pressures. These mixtures, if ignited, may cause injury or property damage.
Additional health and safety information may be obtained from refrigerant
manufacturers.

INTRODUCTION AND OVERVIEW
Contamination of refrigerants in 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 deter-
mine refrigerant type and purity is severely hampered by the presence of air
when attempting to utilize temperature-pressure relations. The develop-
ment of various substitute refrigerants further complicates the ability of a
technician to identify refrigerant purity based upon temperature-pressure
relationships. The substitute refrigerant blends can also introduce a flam-
mability hazard to the technician and the ultimate end user of the vehicle air
conditioning system.
The Ntron Mini ID Refrigerant Identifier will provide an easy and accurate
means to determine if the R134a refrigerant in vehicle air conditioning sys-
tems is of suitable purity. The instrument utilizes non-dispersive infrared
(NDIR) technology to determine the weight concentrations of refrigerant
types R12, R134a, R22, as well as, hydrocarbons and air. Refrigerant purity
is automatically determined for refrigerant R134a by the instrument to elimi-
nate human error.
The instrument is supplied complete with a R134a sample hose, a 12 VDC
power cord and all required plumbing housed within a rugged, portable in-
strument.

PRODUCT DESCRIPTION
The Ntron Mini ID is an economical instrument designed to provide a “PASS”
or “FAIL” indication for R134a Purity. The product will also indicate if an ex-
cess amount of non-condensable gas (air) is present in the system. Excess
“air” will cause poor cooling performance and can be easily corrected by
simply recovering the refrigerant, evacuating the system and recharging the
vehicle. The Mini ID uses a simple hand pump to purge refrigerant from the
sample cell in order to calibrate the instrument. LED’s provide the user with
easy to understand status indicators. Flashing LED’s require user action
while solid LED’s indicate the instrument is performing a task.
The unique brass filter, located between the Coupler and Sample Hose, pro-
vides excellent protection from oil contamination by trapping the oil at the
coupler and preventing it from entering the instrument. If the instrument
continually gives excess air messages, this is an indication that the filter has
been compromised by oil and the filter must be changed.
