4.2 Refrigerants handling instruction
4.2.1 Glossary
• Refrigerant: cold-generating liquid to be only used in the device (e.g. R134a).
• A/C system: air-conditioning system in a vehicle.
• Device: CLIMA TECH EVOLUTION used for pumping out, cleaning and charging A/C
system.
• External tank: tank not designed to be refilled with a fresh refrigerant (e.g. R 134a), which
is used for filling the internal tank.
• Internal tank: tank designed specifically for storage of the refrigerant.
• Phase: performing a specific operation.
• Cycle: sequential performance of individual phases.
• Emptying: emptying an a/c system and storage of the removed refrigerant in the
external tank, without analyzing it or any other processing.
• Recycling: removal of contamination present in the refrigerant by separation of oil and
non-condensing substances and single or multiple filtration through a special device which
reduces humidity, acids and particles.
• Removal: phase in which a refrigerant is sucked-off from the A/C system and gathered in
the internal tank and then disposed of.
• Vacuum phase: a phase in which condensing substances and moisture are removed
from an A/C system using only the vacuum pump.
• Oil injection: refilling oil in A/C system to restore the oil quantity recommended by the
manufacturer.
• Filling: pouring in an A/C system the refrigerant in the quantity recommended by the
manufacturer.
• Washing: A/C system cleaning phase completed to remove any possible contamination.
• Non-condensing gasses: air removed from A/C system or tanks which is not gathered as
a result of refrigerant evaporation.
