Safety Precautions - wigam P2 Mode D'emploi Et Maintenance

a) unit is intended for operator professionally well trained, he must know refrigeration
foundamentals, cooling systems, refrigerants and possible damages that equipments
under pressure could cause
b) read carefully instructions in the literature, strict observance of procedures is main
condition for operator safety, constant declared performances and unit undamaging
c) wear safety glasses and gloves when handling refrigerant; avoid contact with refrigerant,
blindness and injuries may result to operator
d) keep away from flames and hot surfaces; high temperature decomposes refrigerant
releasing toxic
contaminants very dangerous for environment and operator
e) avoid skin contact; refrigerant has a very low boiling temperature (about -30
and freezing may occurs
f) avoid from breathing refrigerant vapor
g) vacuum pump must always be suitably earthed
h) 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
i) vacuum pump is air cooled with integral fan; use only where air can freely circulate
j) before station disconnecting, verify cycle has been completed and valves are closed
so refrigerant will not vented in environment
k) do not attempt to fill cylinders with liquid refrigerant more than 75% of total volume
l) disconnect power before a long period of inactivity
m) 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.
