5 Maintenance
Danger by High Electric Voltages
Death or severe injury caused by an electric shock!
The electrical connections must only be provided by a trained electri-
cian as specified, for example, by the regulations EN 50110-1. Note
the national regulations of the country in which the equipment is being
operated.
Disconnect the electrical connections before disassembling the pump.
Make absolutely sure that the pump cannot be accidentally started.
Observe Safety Informations 0.2.
Capacitors of security class P2 (IAW EN 60252) are used with the pump‘s
single-phase AC motors. The capacitor‘s life cycle is 10,000 h (life cycle
category B acc. to EN 60252).Therefore we recommend to replace motor
or capacitor before reaching the end of its life cycle.
If the pump has pumped harmful substances, contrary to what has been
stated in Section 3.2, ascertain the nature of hazard and take adequate
safety measures. Observe Safety Informations 0.4.
When disposing of used oil, you must observe the applicable environmental
regulations!
Due to the design concept, TRIVAC-B-DOT pumps require very little
maintenance when operated under normal conditions. The work required is
described in the sections below. In addition to this, a maintenance plan is
provided in Section 5.1.
All work must be carried out by suitably trained personnel. Maintenance
or repairs carried out incorrectly will affect the life and performance of the
pump and and will void any warranty claims.
Leybold offers practical courses on the maintenance, repair, and testing
of TRIVAC-B-DOT pumps. Further details are available from Leybold on
request.
If the TRIVAC-B-DOT is used in ambient air which is much contaminated,
make sure that the air circulation and the gas ballast valve are not adver-
sely affected.
When the TRIVAC-B-DOT has been pumping corrosive media we
recommend that possibly planned maintenance work be carried out
immediately in order to prevent corrosion of the pump while it is at
standstill.
In case of special designs and variants please always indicate the serial
number.
