For Your Safety:
PLEASE READ THIS MANUAL IN ITS ENTIRETY BEFORE
ATTEMPTING INSTALLATION OR OPERATION! Attempting to
operate this refrigerant identifier 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.
Read and understand the entire manual BEFORE attempting to operate the instrument.
Identifier Warnings
•Refrigerant Blend Warning: As of January 2004, there are
twelve (12) EPA SNAP “acceptable for use” refrigerants that
are available and legal for use as R12 substitutes. This
refrigerant identifier will not identify any of the
substitutes as pure R12 or pure R134a. Each of the twelve
blends has been tested in the factory laboratory and it has
been confirmed that the substitutes will not “fool” the
instrument. Should one of the blends be encountered, the
instrument will fail the refrigerant and provide a readout of
analysis in terms of percentage by weight concentrations of
R12, R134a, R22 and hydrocarbons only. Due to cross
sensitivity issues of the blends on the sensing device, the
resultant reading will not be correct in the analyzed
concentrations. However, this refrigerant identifier will
never identify any of the blends as pure R12 or pure R134a.
•Sample Filter Warning: Replace the sample filter of the
instrument AS SOON AS RED SPOTS OR DISCOLORATION BEGIN TO
APPEAR ON THE OUTSIDE DIAMETER OF THE WHITE ELEMENT. Failure
to properly maintain and replace the sample filter will
result in severe damage.
•Sample Input Warning: The instrument requires connection of
the supplied sample hose to the LOW SIDE OR VAPOR port of
refrigerant storage cylinders 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 will cause severe damage to the
instrument that will not be covered under warranty repairs.
•Battery Charger Warning: When charging the battery with the
1000mA charger, the charger will become warm. If the charger
becomes hot, unplug the charger immediately! When charging
multiple battery packs, allow the charger to cool between
each battery.

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. Escaping refrigerant vapors will present a
freezing danger.
•To reduce the risk of electrical shock, do not disassemble
the instrument; do not use the instrument in wet or damp
areas.
•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 Identifier on a flat and sturdy surface.
•DO NOT utilize any other hose 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 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.

1. Introduction and Overview
1.1 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 substitute refrigerant
blends can also introduce a flammability hazard to the technician
and the ultimate end user of the vehicle air conditioning system.
The YELLOW JACKET Refrigerant Identifier 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 concentrations of refrigerant types R12, R134a,
R22, as well as, hydrocarbons and air. Refrigerant purity is
automatically determined for refrigerants R12 and R134a by the
instrument to eliminate human error. Pure refrigerant is defined as
a refrigerant mixture that contains 98%, by weight, or greater of
either R12 or R134a.
The instrument is supplied complete with a R12 and R134a sample
hose, a R134a adapter fitting to permit sampling of ACME ported
cylinders, a 12 VDC power cord 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 direct percent by weight concentrations of
R12, R134a, R22 and hydrocarbons. If the sample is determined to be
pure R134a, the instrument will provide a direct readout of the
weight percentage of air within the sample. Note that the
instrument does not consider air to be a contaminate since it can be
removed by most refrigerant recycling equipment. Since air is not
considered to be a contaminate, it is possible to read 100% R134a
plus 5% air. The instrument only considers the weights of the
refrigerant and contaminates in the total mixture for R134a as air
contamination in R12 systems causes only minor performance
degradation.
6

The instrument interfaces with the user with an LCD graphic display,
status indicator lamps, push button communication switches and an
alarm horn. Alarm indications are provided to alert of instrument
fault conditions or contaminated refrigerant presence. Direct
percent by weight concentrations of the sample refrigerant is
provided on the display as well as user directions and prompts. An
optional on-board printer (Model RI-2004DXP) is available to print
on-the-spot customer confidence receipts.
The YELLOW JACKET Refrigerant Identifier will provide the
refrigerant technician with absolute knowledge of refrigerant
purity and protection against refrigerant contamination and
potential flammability.

2.3 Calibration
Each time the refrigerant identifier begins a new test cycle it must
first self calibrate. The calibration takes 30 seconds (Figure 4)
and brings fresh air into the unit via an internal pump. This fresh
air purges any excess refrigerant from the unit and ensures accurate
test results. Calibration requires that the hose be disconnected
from the vehicle or refrigerant cylinder. During calibration, the
screen shown in Figure 5 will appear reminding the user to change
the filter under certain conditions. For additional details on how
and when to change the filter, refer to Section 3, Maintenance and
Troubleshooting. The calibration of the unit will expire after
approximately five minutes of inactivity. If this occurs, the
screen shown in Figure 6 will be displayed requiring the calibration
to be initiated again.

3.3 Changing the Sample Filter
When inspecting the sample filter, look completely around the entire
outside diameter of the white filter element located inside of the
clear plastic housing. Look for red spots or the beginnings of
discoloration on the white outside diameter of the element. Do not
look into the round ends of the white element for red spots or
discoloration. The round ends of the filter may always appear red.
If red spots or discolorations are discovered, the sample filter
requires replacement to prevent the influx of particulate and oil
mists into the instrument.
Obtain a replacement filter. Remove the existing filter from the
retaining clip of the instrument by pulling straight up and out.
CAREFULLY remove the flexible, black rubber tubing connections from
both ends of the existing filter. DO NOT allow the tubes to slip
back into the internal portion of the case. Discard the existing
filter in an environmentally friendly manner.
Install the tube ends onto the barbs of the replacement filter,
taking note to align the flow arrow of the filter with the flow
arrow of the instrument top panel. CAREFULLY slide the tubing back
into the internal portion of the instrument and seat the new filter
into the retaining clip. Inspect the sample hoses for signs of oil
entrapment. Replacement of the sample filter usually requires
cleaning or replacement of the sample hoses.
3.4 Cleaning the Sample Hoses
Inspect the inside diameter of the inner tube for signs of oil build
up, dirt, obstructions, kinks, cuts, fraying, or any other signs of
wear. Oil contamination can be cleaned out of sample hoses as
directed below. Hoses that show signs of wear should be replaced
immediately to avoid dangers of rupture or bursting.
Remove the hose from the instrument and flush with isopropyl alcohol
until the oil is thoroughly cleansed from the inner tube.
Warning: Flush hoses away from sparks, open flames or other
ignition sources and in an area that is well ventilated.
Dry the hose by blowing clean, dry nitrogen or shop air through the
inner hose or by allowing the hose to air-dry for several hours.
Take care to not dry the hose with shop air that is lubricated.
When the hose is completely dry, re-inspect the hose for signs of
wear, as described above, and replace if wear is evident.
3.5 Changing the Printer Paper
The YELLOW JACKET Refrigerant Identifiers that are equipped with on-
board printers use an inexpensive thermal paper for printing. The
paper roll should be changed when a red stripe appears on the left
side of the printout.
