This manual provides important information on how to operate and maintain Bacharach’s Pur•Chek™ Pro HVAC
Diagnostic Refrigerant Analyzer.
To assure operator safety and proper use of the Pur•Chek™ Pro, please read, understand, and follow the con-
tents of this manual.
1.2 Warnings & Cautions
When used in this manual or as labeled on the Pur•Chek™ Pro, the following hazard symbols and/or associ-
ated words are defined 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 profiled using the Pur•Chek™ Pro.
Sample Filter Warning: Replace the sample filter of the instrument AS SOON AS RED
SPOTS OR DISCOLORATION BEGIN TOAPPEAR 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 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 instru-
ment 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 500 psig.
• NEVER obstruct the air intake, sample exhaust or case vent ports of the instrument during use.

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 relation-
ships. The substitute refrigerant blends can also introduce a flammability hazard to the technician and the
ultimate end user of the air conditioning system.
The Bacharach Pur•Chek™ Pro Diagnostic Refrigerant Analyzer provides a fast, easy and accurate means to
determine refrigerant purity in refrigerant storage cylinders or directly in air conditioning systems. The instru-
ment utilizes non-dispersive infrared (NDIR) technology to determine the weight concentrations of multiple
refrigerant types. 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 one of the two supplied sampling hoses and presented to
the sensing device. The instrument provides the user with direct percent by weight concentrations. Note that
the instrument does not consider air to be a contaminant.
The instrument interfaces with the user with an LCD graphic display, status indicator lamps, push button com-
munication switches and an alarm horn. Alarm indications are provided to alert of instrument fault conditions.
Direct percent by weight concentrations of the sample refrigerant is provided on the display as well as user
directions and prompts. A built-in printer is provided to print an on-the-spot analysis report.
The Bacharach Pur•Chek™ Pro provides the refrigerant technician with excellent knowledge of refrigerant type
and purity as well as protection against refrigerant contamination and potential flammability.

3 Components
3.1 Base Unit
The Pur•Chek™ Pro base unit houses the Graphic Display, Infrared Bench, Electrical Connections, and Printer
Module. These components require no maintenance, therefore there are no serviceable components inter-
nal to the instrument, and disassembly will void the warranty.

3.2 Low Side Vapor Sample Hose
The 6 foot (1.8 meter) Low Side Vapor Sample Hose is constructed of a polyurethane tube. Abrass flow restric-
tor acts to reduce pressure at the sample connection point and reduce the introduction of harmful oil into the
machine. The maximum inlet pressure is 500 psig. The hose is provided with an instrument inlet port mating
connector on one end and a 1/4” SAE female flare coupling nut on the service end.

Instruction 2100-90016
3.3 High Side Liquid Sample Hose
The 6 foot (1.8 meter) High Side Sample Hose is constructed of a polyurethane tube with an oil reservoir. A
brass flow restrictor acts to transform Liquid refrigerant to Vapor at the sample connection point while the Oil
Trap Syringe collects oil and provides a means of expulsion after the test is complete. The maximum pressure
is 500 psig. The hose is provided with magnet for attaching it to the tank and an instrument inlet port mating
connector on one end and a 1/4” SAE female flare coupling nut on the service end.

3.4 AC Power Adapter
The Pur•Chek™ Pro is powered via a 110/220 VAC, 50/60 Hz power transformer. This transformer is included
with each unit and converts a standard 110/220 VAC, 50/60 Hz wall outlet to 12VDC to power the device. An
optional internal and rechargeable battery kit is available separately. Note: Use of any other power source may
cause damage to the unit and void the warranty.
3.5 Control Panel
The Control Panel serves as the main user interface. The Control Panel features three soft key buttons that
change their function as the instrument changes modes. The current function for each button is displayed by
the soft key label at the bottom of the graphic display. Red and Green LED’s at the top of the Control Panel are
used for visual status indications.
