Safety precautions
This equipment is designed for trained personnel only, who must know the refrigeration
fundamentals, cooling systems, refrigerants and possible damage that pressurized equipment may
cause.
Only use refrigerant R134a. The unit must not be used with a different refrigerant than the one it has
been designed for.
Carefully read the instructions contained in this manual; strict observance of the procedures
described is fundamental to the operator’s safety, the perfect state of the unit and constant
performances as declared.
The unit must always work under the operator’s direct supervision
Before performing any operation, make sure that the hoses used for connections have been
previously evacuated and that they do not contain non-condensable gases.
Avoid skin contact; the low boiling temperature of the refrigerant (about -30°C) can cause freezing.
Avoid breathing refrigerant vapours.
It is recommended to wear suitable protections like safety glasses and gloves; contact with refrigerant
may cause blindness and other personal injuries.
Do not smoke near the unit and do not operate near open flames and hot surfaces; the high
temperatures decompose the refrigerant releasing toxic and caustic substances which are hazardous
for the operator and the environment.
Always make sure that the unit is connected to a suitably protected mains supply provided with an
efficient earth connection.
Before performing maintenance operations or when the unit will not be used for a long period of
time, turn the unit off by turning the main switch to 0 and disconnect the power supply cord;
absolutely follow the sequence of operations.
Operate the unit only in locations with suitable ventilation and a high number of air changes.
Before disconnecting the unit, make sure that the cycle has been completed and that all valves are
closed in order to avoid release of refrigerant to the atmosphere
Never fill any tank with liquid refrigerant to more than 75% of its maximum capacity.
During operations avoid release of refrigerant to the environment; this precaution is required by
international environmental standards and is essential to avoid difficult leak detection in a refrigerant
polluted environment.
Protect the unit from dripping.
Do not expose the unit to direct sunlight, rain and to the inclemency of the weather.
Do not modify the calibration of safety valve and control systems.
If you recover refrigerant from a cooling system equipped with a water evaporator and/or condenser,
it is necessary to drain water from the evaporator and/or condenser or to keep the circulation pump
running during the entire recovery operation in order to avoid frosting.
Disconnect the unit from the power supply if not used.
General information
Perform a good vacuum cycle before charging refrigerant into the system!
Perform the refrigerant charging phase after having charged oil or UV!
Empty the used oil bottle before starting the recovery phase!
WARNING
!
If you do not pay attention to the above safety precautions, you could damage the recovery unit and the
car A/C system!
