Special safety instructions
It is essential to read and understand the general safety instructions in the Safety appendix
(Page 22 and following)!
Unit is intended for operator professionally well trained, he must know refrigeration fundamentals, cooling
systems, refrigerants and possible damages that equipments under pressure could cause.
Wear safety glasses and gloves when handling refrigerant; avoid contact with refrigerant, blindness and
injuries may result to operator.
Keep away from flames and hot surfaces; high temperature decomposes refrigerant releasing toxic
contaminants very dangerous for environment and operator.
Avoid skin contact; refrigerant has a very low boiling temperature (about -30°C/-22°F) and freezing may
occurs.
Avoid from breathing refrigerant vapour.
Even if the pump temperature is not expected to rise a high level during use, it is advisable to locate the
unit so that users cannot make contact with the casing, as burns may result.
Vacuum pump is air cooled with integral fan; use only where air can freely circulate.
Before station disconnecting, verify cycle has been completed and valves are closed so refrigerant will not
vented in environment.
Do not attempt to fill cylinders with liquid refrigerant more than 75% of total volume.
During operations, do not vent refrigerant in environment. This precaution, also required by international
laws in force for environmental protection, is essential to avoid difficult leaks detection due to ambient
polluted by refrigerant.
