1.4. General Warnings and Cautions
ALWAYS wear eye and skin protection when working with refrigerants. Escaping
•
refrigerant vapors will present a freezing danger.
•
ALWAYS turn the compressor off before connecting the instrument to an air
conditioning system.
•
ALWAYS inspect the sample hose before each use. Replace the hose if it appears
cracked, frayed, obstructed or fouled with oil.
•
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 analyzer on a flat and sturdy surface.
•
To reduce the risk of electrical shock, DO NOT disassemble the instrument; do not use
the instrument in wet or damp areas.
•
Some systems may contain hydrocarbons or flammable refrigerants. This analyzer is
designed with sealed heat sources and without sparking components. ALWAYS
ensure adequate ventilation and ALWAYS take proper precautions when working with
refrigerants.
•
DO NOT breathe refrigerant and lubricant vapor or mist. Exposure may irritate eyes,
nose, and throat. If accidental system discharge occurs, immediately ventilate the work
area.
•
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 from the Low Side does not contain or
will not emit heavy loads of oil or liquid.
•
DO NOT expose unit or external components to rain or moisture. Protect the unit by
keeping it in the storage case when not in use.
•
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.
