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.
• Refrigerant test: Analysis of the composition of the refrigerant.
• 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.

8COOLIUS Y50A
• 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.
• Gloves and goggles should be worn - contact with the refrigerant can cause blindness and other physi-
cal injury to the user.
• Avoid inhalation of vapours from the refrigerants and contact of the refrigerant with skin.
• Do not switch on the machine unless the machine is going to be used immediately. Cut o󰀨 the electrical
power supply prior to long intervals in which the machine will not be used.
• Attention: Ensure that all valves are closed before making connections between the machine and an
A/C system or an external tank.
• Attention: Ensure that the process has been completed and that all valves are closed before discon-
necting the machine.
• Attention: All of the exible hoses may contain refrigerant under high pressure. Exercise extreme cau-
tion when disconnecting the service hoses.
• Attention: The machine and A/C system in vehicles containing refrigerant should not be tested with
compressed air. Some mixtures of air and refrigerant have proven to be combustible at high pressure
levels. These mixtures are potentially hazardous and there is a risk of re and explosions that can
cause damage to property and personal injury.
Additional medical and safety information can be obtained from the manufacturers of the oils and refrig-
erants.
2.3 Guidelines for handling refrigerants
Precautions for Refrigerant Storage
The refrigerant to be removed from a system must be handled carefully in order to prevent or minimise the
possibilities of di󰀨erent refrigerants mixing.
The tank used for storing refrigerants must be assigned to specic refrigerants to avoid di󰀨erent refrigerants
mixing
Recycling Capacity
The recycling machine’s lter system should be replaced regularly in order to maintain the e󰀩ciency of the
recycling machine

9COOLIUS Y50A
General Notions
Before re-introducing refrigerant into the system, the system itself must be evacuated and cleaned.
In order to be sure that the system is free of contaminating agents before introducing the refrigerant, all the
procedures described in this instruction manual must be followed.
Clean and maintain the machine regularly, especially when highly contaminated refrigerant is used: it
is extremely important that contamination from the previous operation is not transferred to subsequent
operations.
2.4 Safety devices
The machine is equipped with the safety devices required from the European Directives:
• Electric safety switch
• Safety valve
CAUTION! Danger of injury due to manipulation.
DO NOT MODIFY THE SAFETY DEVICES.
2.5 Not condensable gas discharge
A not condensable gas discharge valve is installed to allow these gasses to be released.
The not condensable gas discharge valve could generate noises.
WARNING! Risk of injury from escaping gases under high pressure.
Make sure that you never come in contact with the drain valve!
2.6 Ventilation Safety System
The machine is designed for the refrigerant 1234yf classied as ammable.
For this reason, the machine is equipped with a ventilation security system which has the task, in case of
leakage of the circuit, to avoid the formation of pockets of refrigerant.
It is forbidden to obstruct the inlet grid of the fan.
The user must monitor the e󰀩ciency of the ventilation security system and in case of anomaly of the same
must switch o󰀨 the machine.
In addition, the internal vessel is equipped with a normally closed electric valve which is activated only when
the machine is ON.
2.7 The work environment
• The machine must be used in open environments or in places equipped with good ventilation (at least 4
changes of air per hour).
• The unit has been designed for use at a maximum altitude of 1000 m above sea level, within a tempera-
ture range of +10 and +49°C and with a maximum humidity of 50% at +40°C. Protect the machine from
direct sun rays, rain, etc…
• Operate in su󰀩ciently lit conditions.

4.6 Automatic Internal ushing
The machine is equipped with two oil bottles (one for the PAG oil and one for POE oil). Due to low compati-
bility between the two kinds of oil, it is strongly suggested to avoid the mixing between the two.
In order to avoid contamination, the Automatic Internal ushing function performs a machine cleaning phase
at the end of each process involving the oils.
This function can be deactivated if sure that only one type of oil is used with the machine (also in case of
recovery!).
IMPORTANT NOTE: Excluding this function may cause anomalies in the A/C system and could
create hazardous situations for the user (electric shocks on the A/C compressor unit)
At the end of Vessel Charge, A/C Pressure Test, A/C Data-
Base, Full Service, Open Program (only the ones including
“Recovery” and/or “A/C System Charge”), the display shows:
Perform the instruction, then press START key to conrm.
