COOLIUS A50 - Safety Instructions and Guidelines; General Safety Rules

7COOLIUS A50
2 Important safety instructions
The user should follow the “general safety rules”, and use the machine according to the “intended use” and
the instructions of this operating manual.
Therefore, the user is not exposed to any risk if the general safety rules reported below are followed with
proper use and maintenance of the machine.
2.1 Glossary of terms
• Machine: The machine relative to this operating manual.
• Refrigerant: Fluid reported on the identication label.
• A/C system: Air-conditioning system in the vehicle.
• External bottle: New Refrigerant used to ll the internal vessel.
• Internal vessel: Refrigerant storage tank.
• Process: Execution of an individual function (Ex. Recovery).
• Cycle: Execution of more processes.
• Recovery: The recovery of refrigerant in any condition and its storage in a container outside the A/C
system, without necessarily undergoing analysis or treatment of any kind.
• Recycling: A reduction of the contaminating substances in used refrigerants through oil separation, the
recovery of incondensable and their single or multiple passages through elements that enable a reduc-
tion in humidity, acidity and gasses.
• Disposal: Recovery of refrigerant to store it for subsequent distribution or disposal.
• Vacuum: Phase in which air and moisture are evacuated from an A/C system solely by means of a
vacuum pump.
• Oil charge: Introduction of oil inside an A/C system for the purpose of maintaining the amount of oil
specied by the manufacturer.
• UV dry charge: Introduction of UV dye inside an A/C system in order to detect possible leaks by means
of a UV lamp.
• Refrigerant charge: Phase during which refrigerant is introduced into an A/C system in the amount
specied by the manufacturer.
• Flushing: at the purpose to clean the A/C system or components, liquid refrigerant is ushed through it,
in order to do so a special device and adapters are needed.
• Nitrogen pressure test: Introduction of nitrogen inside an A/C system in order to detect possible leaks
2.2 General safety rules
• This machine is intended for use by QUALIFIED PERSONNEL only. Such users must have a knowl-
edge of the basics of refrigeration, refrigeration system, refrigerants and the potential hazards that unit
under high pressure can cause.
• It’s essential to supervise the machine at all times.
• DO NOT modify the safety devices
• DO NOT use external tanks or other storage tanks that have not been type-approved or that lack safety
valves.
• DO NOT use the machine near open ames and hot surfaces. At high temperatures, the refrigerant de-
composes, releasing toxic and chemical substances that are hazardous for users and the environment.
• It’s essential to use only the refrigerant indicated on the identication label. Mixtures with other types of
refrigerant will seriously damage the cooling and refrigeration system, as well as the machine.
