1 Introduction
Thank you for purchasing the Bacharach R•22id Refrigerant Identifi er.
The Bacharach R•22id is an economical instrument designed to provide a “PASS” or “FAIL”
indication for R22 purity. The product will also indicate if an excess 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 and recharging the system.
The R•22id uses an internal electric 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 fi lter, located between the Service Connector and Sample Hose, provides
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 indica-
tion that the fi lter has been compromised by oil and the fi lter must be changed.
Contamination of refrigerants in 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 R•22id Refrigerant Identifi er will provide an easy and accurate means to
determine if the R22 refrigerant in air conditioning systems is of suitable purity. The instrument
utilizes non-dispersive infrared (NDIR) technology to determine the weight concentrations of
refrigerant type R22, as well as, hydrocarbons and air. Refrigerant purity is automatically deter-
mined for refrigerant R22 by the instrument to eliminate human error.
Please read this manual in its entirety before attempting installation or operation. Attempting to
operate the R•22id without fully understanding its features and functions may result in unsafe
conditions.
