2 Warnings and Cautions
The Mini ID R-1234yf, hereafter also referred to as "the device," is a gas analyzer intended to provide a
fast, easy, and accurate means to determine refrigerant purity in refrigerant storage cylinders or directly in
air conditioning systems. The device is specified to support compliance with federal, state, and local safety
codes that govern emissions.
2.1Analyzer Warnings
•Install, operate, and maintain the device in strict accordance with its labels, cautions, warnings,
instructions, and stated limitations.
•For any maintenance procedure provided in this manual, use only genuine MSA replacement parts.
Repair or alteration of the device beyond the scope of these maintenance instructions or by anyone
other than authorized service personnel can cause incorrect operation of the device. For a list of
approved parts and how to order them, refer to the (9.2 Spare Parts List).
•Never expose the device to water, rain or liquids when charging.
•The device is not intrinsically safe. Do not use the device in areas classified as hazardous or
locations where explosive concentrations of combustible gases or vapors can occur.
•Never admit any sample into the instrument at pressures in excess of 300 psig. Pressures above
300 psig can lead to damage within the device and create a bursting hazard.
•Some vehicles may contain flammable refrigerants such as hydrocarbons. R-1234yf is considered
a flammable substance. Less than 2 grams of refrigerant are vented with each sample.
•When powering the device with the battery clips, the battery clips may become warm. If the battery
clips become warm, unplug the cord immediately.
•Do not utilize any hose(s) other than the MSA hose supplied with the instrument. The use of other
hose types will introduce errors into the refrigerant analysis and instrument calibration.
•If the device is used in a manner not specified by the manufacturer, the protection by the device
may be impaired.
•Properly vent the exhaust of the device to a safe area. Improper venting of the exhaust can cause
serious personal injury or death.
•Always turn the compressor or automobile engine off before connecting the instrument to an air
conditioning system.
Failure to follow these warnings can result in serious personal injury or death.
2.2 General Cautions
•Always wear eye and skin protection when working with refrigerants. Escaping refrigerant vapors
will present a freezing danger.
•Do not direct refrigerant escaping from the sample hose toward exposed skin or toward the face.
•Do not direct refrigerant vapors venting from hoses towards the skin. Refrigerant can cause serious
burns if in contact with the skin.
•Do not breathe refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, and
throat.
•Use recycling equipment certified to meet the requirements of SAE J2788, J2843, J3030 or J2851
to remove refrigerant from the A/C system. If accidental system discharge occurs, immediately
ventilate the work area. There must be adequate ventilation in the vehicle servicing area.
•Do not utilize the coupler on the service end of the Sample Hoses 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.

P a g e | VI
Failure to follow these cautions can result in minor or moderate injury.
2.3General Notices
•Operate this device with vehicles or cylinders marked to contain R-1234yf. Cross contamination
with other refrigerant types causes severe damage to the A/C system, to service tools, and
equipment. Do NOT attempt to adapt the unit for another refrigerant. Do NOT mix refrigerant types
in a system or in the same container.
•Always inspect the sample hose before each use. Replace the hose if it appears cracked, frayed,
obstructed, or fouled with oil.
•Replace the sample hose AS SOON AS LIQUID, OIL OR DISCOLORATION BEGIN TO APPEAR
ON THE INSIDE DIAMETER OF THE SAMPLE HOSE. Failure to properly maintain and replace
the sample hose will result in severe damage or inaccurate results.
oDO NOT attempt to introduce liquid or samples heavily laden with oil into the Low Side
sampling hose configuration. Damage caused to the device due to the use of the wrong
hose configuration on the wrong port will void the warranty.
•Connection to power sources greater than 13 VDC could cause “out of warranty” damage.
•Avoid use of the device where condensation can collect. Condensation can clog or block sample
lines, which will prevent the device from receiving new or fresh gas samples in the area being
monitored.
•To ensure correct overall operation of a gas detection instrument, test a known virgin sample of
gas for which it was calibrated. Do a calibration check prior to each use.
•Do not disassemble the instrument. There are no serviceable components internal to the
instrument and disassembly will void the warranty.
•Always place the analyzer on a flat and sturdy surface.
•Always verify that the refrigerant, tested from the Low Side, does not contain, or will not emit heavy
loads of oil or liquid. Heavy loads of oil or liquid can enter the device and cause it to become
inoperable.
•Never obstruct the air intake, sample exhaust or case vent ports of the instrument during use.
Obstruction can lead to calibration faults or operational errors in the device.
Failure to follow these cautions can result in minor or moderate injury.

4 Product Description
4.1 General
The Mini ID Refrigerant Identifier will provide an easy and accurate means to determine if the
R-1234yf refrigerant in vehicle air conditioning systems is of suitable purity. The instrument
utilizes non-dispersive infrared (NDIR) technology to determine the weight concentrations of
R-1234yf. Refrigerant purity is automatically determined for refrigerant R-1234yf by the
instrument to eliminate human error.
The instrument is supplied complete with an R-1234yf sample hose, a 12 VDC power cord
and all required plumbing housed within a rugged, portable instrument. The Mini ID is an
economical instrument designed to provide a “PASS” or “FAIL” indication for R-1234yf 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 the system, and recharging the vehicle. The
Mini ID uses a mechanical pump to purge refrigerant from the sample cell to calibrate the
instrument. LEDs provide the user with easy-to-understand status indicators. Flashing LED’s
require user action while solid LEDs indicate the instrument is performing a task.
The unique brass filter, located between the coupler 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 displays excess air messages, this is an
indication that the filter has been compromised by oil and the filter must be changed.
