Important Safety Information
Failure to observe the following precautions could result in serious
personal injury!
■
Before beginning with any maintenance or service work on the TRIVAC
NT, disconnect the pump from all power supplies (lockout/tagout).
■
Do not operate the pump with any of the covers removed. Serious injury
may result.
■
If exhaust gases must be collected or contained, do not allow the exhaust
line to become pressurised.
■
Make sure that the gas flow from the exhaust port is not blocked or
restricted in any way.
■
Only
those pumps which are equipped with an Atex certified motor are
suited for operation in explosion hazard areas.
■
The standard version of the TRIVAC NT is not suited for operation in
explosion hazard areas.
■
Before starting up for the first time, the motor circuit must be equipped
with a suitable protective motor switch. Please take note of the informati-
on in these Operating Instructions and on the electric motor (wiring dia-
gram).
■
When pumping toxic, chemical, radioactive and corrosive gases as well as
pyrophorous substances, the operating company is under the obligation
to comply with the national and international safety regulations and guide-
lines. Regarding the suitability of the TRIVAC NT pumps for special appli-
cations in which such gases, respectively substances shall be pumped,
Oerlikon Leybold Vacuum should be consulted first.
■
The TRIVAC NT pumps including the accessories are fundamentally not
suited for pumping of combustible and explosive gases or vapours.
Mixtures of substances may, regarding the fire and explosion risk be criti-
cal or uncritical. The operating company is under the commitment to ana-
lyse this and rate the hazard potential accordingly so as to therefrom deri-
ve the necessary safety measures which must be introduced.
■
If ignitable or pyrophorous substances are present in the equipment you
must ensure that:
■
no air can enter into the equipment,
■
the system is leak-tight,
■
by means of purging with inert gas (for example through a nitrogen
purge) all ignitable gases or vapours which enter into the pump through
the pump’s inlet are diluted and/or by means of an inert gas purge the
concentration of ignitable gases in the pump and in the exhaust gas line is
reduced to less than a quarter of the lower explosion limit published for
the respective gases.
