COOLIUS Y50A
•
Refrigerant charge:
Phase during which refrigerant is introduced into an A/C system in the amount
specified by the manufacturer.
•
Flushing:
at the purpose to clean the A/C system or components, liquid refrigerant is flushed 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 flames 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 identification 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 off 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 flexible 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 fire 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 different refrigerants mixing.
The tank used for storing refrigerants must be assigned to specific refrigerants to avoid different refrigerants
mixing
Recycling Capacity
The recycling machine’s filter system should be replaced regularly in order to maintain the efficiency of the
recycling machine
