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 AC system off before connecting the instrument to an air condi-
tioning 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 300 psig.
• DO NOT utilize the connection fi tting supplied on the service end of the Sample
Hose for any application other than with the instrument.
• NEVER obstruct the air intake, sample exhaust or case vent ports of the instru-
ment during use.
• WARNING: This Identifi er must not be operated in fl ammable atmospheres.
• CAUTION: Should be operated by certifi ed personnel.
• Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate
eyes, nose and throat. To remove refrigerant from the A/C system, use service
equipment design certifi ed for the application. Additional health and safety infor-
mation may be obtained from refrigerant and lubricant manufacturers.
• CAUTION: Do not pressure test or leak test A/C service equipment and/or air
conditioning systems with compressed air. Some mixtures of air and refrigerant
have been shown to be combustible at elevated pressures. These mixtures, if
ignited, may cause injury or property damage. Additional health and safety infor-
mation may be obtained from refrigerant manufacturers.
