1.2 Warnings & Cautions
When used in this manual or as labeled on the Pur•Chek™, the following hazard symbols and/or associated
words are defi ned as follows:
WARNING: This symbol and/or the use of the word WARNING indicates a potential hazard
associated with the use of this equipment. It calls attention to a procedure, practice, condition,
or the like, which if not correctly performed or adhered to, could result in death or serious injury.
WARNING: This symbol and/or the use of the word WARNING indicates a potential hazard
from electrical shock. It calls attention to a procedure, practice, condition, or the like, which if
not correctly performed or adhered to, could result in death or serious injury.
CAUTION: This symbol and/or the use of the word CAUTION indicates a potential hazard
associated with the use of this equipment. It calls attention to a procedure, practice, condition,
or the like, which if not correctly performed or adhered to, could result in minor or moderate
injury.
IMPORTANT: The use of the word IMPORTANT in this manual calls attention to a procedure,
practice, condition, or the like, which if not correctly performed or adhered to, could result in
incorrect performance of or damage to the equipment and may void the warranty.
1.2.1 Analyzer Warnings
Refrigerant Blend Warning: The HVAC industry is continually introducing new refrigerants.
Many of these new blends can be profi led using the Pur•Chek™.
Sample Filter Warning: Replace the sample fi lter 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 fi lter 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 air conditioning systems.
DO NOT attempt to introduce liquid or samples heavily laden with oil into the low side sampling
hose. DO NOT connect the sample hose to the HIGH SIDE or LIQUID port!
Damage caused to the instrument due to the use of the wrong hose on the wrong port will void
the warranty.
Battery Charger Warning: When charging the optional battery with the 1000 mA 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.

1.2.2 General Warnings & 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 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 Identifi er on a fl at 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 500 psig.

1.5 Functional Overview
Contamination of refrigerants either in storage cylinders or 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 fl ammability hazard to the technician and the
ultimate end user of the air conditioning system.
The Bacharach Pur•Chek™ Advanced Refrigerant Identifi er provides a fast, easy and accurate means to deter-
mine refrigerant purity in refrigerant storage cylinders or directly in 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. In addition, the unit will indicate the presence of R410A if the refrigerant
tested matches the internal profi le established for virgin R410A. Refrigerant purity is displayed on the LCD
Screen. The user must determine acceptable levels of purity based on their recovery or use standards.
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 contaminant
since it can be removed by most refrigerant recycling equipment. Since air is not considered to be a contaminant, it is possible to read 100% R134A plus 5% air. The instrument only considers the weights of the refrigerant and contaminants in the total mixture for R134A as air contamination in R12 and R22 systems causes only
minor performance degradation.
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 factory-installed printer (Model 2100-
8002) is available to print an on-the-spot analysis report.
The Bacharach Pur•Chek™ Advanced Refrigerant Identifi er provides the refrigerant technician with excellent
knowledge of refrigerant purity and protection against refrigerant contamination and potential fl ammability.
