General 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. 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 hose assembly 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 which is tested from the Low Side 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 500 psig .
•
NEVER obstruct the air intake, sample exhaust or case ventilation ports of the
instrument during use.
