Safety Precautions - wigam DIP401 Mode D'emploi Et Maintenance

a) These pumps are designed for trained personnel only, who must know the
refrigeration fundamentals, cooling systems, refrigerants and the possible damage
that pressurized equipment may cause.
b) Carefully read the instructions contained in this manual; strict observance of the
procedures described is fundamental for the operator's safety, the perfect state of the
pump and constant performances as declared.
c) Wear suitable protections like safety glasses and gloves; contact with refrigerant may
cause blindness and other personal injuries.
d) Do not operate near open ames and hot surfaces; high temperatures decompose
the refrigerant releasing toxic and caustic substances which are hazardous for the
operator and the environment.
e) Avoid skin contact; the low boiling temperature of the refrigerant (about -40°C) can
cause freezing.
f) Avoid breathing refrigerant vapors
g) Always make sure that the pump is connected to a suitably protected mains supply
provided with an efficient earth connection
h) Even if the pump's temperature never reaches high values during evacuation, make
sure to place the pump so that it can never cause damages to the operator, such as
small burns.
i) Operate the pump only in locations with suitable ventilation and a high number of air
changes.
j) Before disconnecting the pump, make sure that the cycle has been completed and
that all valves are closed in order to avoid release of refrigerant to the atmosphere.
k) Never ll any tank with liquid refrigerant to more than 75% of its maximum capacity.
l) When the unit will not be used for a long period of time, disconnect the power supply
cord.
m) 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.
