Important Safety
Information
■
Before beginning with any maintenance or service work on the
TRIVAC B, disconnect the pump from all power supplies.
■
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.
■
The standard version of the TRIVAC B is not suited for operation in
explosion hazard areas. For this purpose there are special TRIVAC B
Atex Pumps. Contact us before planning to use the pump
under such circumstances.
■
Before starting up for the first time, the motor circuit must be
equipped with a suitable protective motor switch. Please take
note of the information in these Operating Instructions or on
the electric motor (wiring diagram).
■
The TRIVAC B is
not suited
for pumping of:
■
combustile and explosive gases and vapours
■
radioactive and toxic substances
■
pyrophorous substances
■
Avoid exposing any part of the human body to the vacuum.
■
Never operate the TRIVAC B without a connected intake line
or blank flange at the intake port.
■
The location at which the TRIVAC B (including its accessories)
is being operated should be such that angles over 10° from
the vertical are avoided.
■
The location of the TRIVAC B should be such that all controls
are easily accessible.
■
Under certain ambient conditions the TRIVAC B may attain a
temperature of over 70 °C (158 °F). There then exists the
danger of receiving burns.
Note the symbols on the pump pointing to the hazards, and in the
case of a hot pump wear the required protective clothing.
■
The noise level of the TRIVAC B is between 52 and 62 dB(A). Introduce
suitable hearing protection.
■
Before pumping oxygen (or other highly reactive gases) at concen-
trations exceeding the concentration in the atmosphere (> 21 % for
oxygen) it will be necessary to use a special pump. Such a pump will
have to be modified and degreased, and an inert special lubricant
(like PFPE) must be used.
■
Before commissioning the TRIVAC B, make sure that the
media which are to be pumped are compatible with each
other so as to avoid hazardous situations. All relevant safety
standards and regulations must be observed.
Warning
Non-compliance with the follo-
wing precautions can result in
severe injury!
