Mastercool 69134-A REFRIGERANT IDENTIFIER FOR R134a - Manual (Page 6)

•
Always wear eye and skin protection when working with refrigerants. Es-
caping refrigerant vapors will present a freezing danger.
• To reduce the risk of electrical shock, do not disassemble the instru-
ment; 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 compo-
nents 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 instru-
ment. The use of other hose types will introduce errors into the refriger-
ant 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.
• WARNING – This Identifier must not be operated in flammable atmos-
pheres.
• CAUTION – Should be operated by certified personnel.
• Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may
irritate eyes, nose and throat. To remove HFC-134a from the A/C system,
use service equipment certified to meet the requirements of SAE J2788.
Additional health and safety information may be obtained from refrigerant
and lubricant manufacturers.
• CAUTION – Do not pressure test or leak test HFC-134a service equipment
and/or vehicle air conditioning systems with compressed air. Some mix-
tures of air and HFC-134a have been shown to be combustible at elevated
pressures. These mixtures, if ignited, may cause injury or property damage.
Additional health and safety information may be obtained from refrigerant
manufacturers.

WARNING: Be sure to turn off the vehicle and let it rest for 3 minutes.
1) Connect the power cable to the power port located on the bottom of the
instrument.
2) Connect the power clips to the 12 VDC battery source. Be sure to ob-
serve the correct polarity.
3) The lights will sequence, press “NEXT” to begin the “WARM UP”.
4) After approximately 90 seconds, the “CALIBRATING” light will flash.
5) Fully squeeze the calibration bulb 5 times and press “NEXT”.
6) The “CALIBRATING’ light will illuminate for approximately 60 seconds.
7) When the Analyzing light begin to flash, connect hose to the vehicles low
side service port and then press “NEXT”.
8) The Analyzing light will illuminate for approximately 45 seconds while the
test is in progress.
9) The “PASS”/”FAIL” light will then provide the test results (See The Test
Results)
10) Disconnect the sample hose from the vehicle, press the “NEXT” button
and squeeze the calibration bulb 5 times. Remove the power and the

1) After the Analysis is complete, the “PASS” or “FAIL” light will flash.
a) “PASS” indicates the refrigerant tested is 95% or greater R134a and
is suitable for recovery.
b) “FAIL” indicates the refrigerant tested is less than 95% R134a and
should not be recovered without special equipment.
c) The EXCESS AIR” light will illuminate in conjunction with the “PASS”
or “FAIL” if the instrument determines that a significant amount of
air is present. (See Help/Troubleshooting) .
