Maintenance safety
WARNING:
Risk of injury or damage to equipment. Follow the safety instructions and take note of all
appropriate precautions.
•
When referring to a manual supplied as a Supplementary Publication, all of the
WARNING and CAUTION instructions in the manual must be obeyed.
•
A suitably trained and supervised technician must maintain the T-Station 85.
•
Allow the system to cool (so that it is at a safe temperature for skin contact) before
starting maintenance work. Make sure the system is switched off in case the thermal
overload device restarts the system.
•
Check that all the required parts are available and of the correct type before starting
work.
•
Ensure that the maintenance technician is familiar with the safety procedures which
relate to the pump oil and the products processed by the pumping system.
•
Isolate the system and other components from the electrical supply so that they
cannot be operated accidentally.
•
Do not reuse O-rings and seals if they are damaged.
•
Dispose of components, grease and oil safely (refer to
Disposal
on page 32).
•
Protect sealing faces from damage.
•
Leak testing the system is recommended after maintenance. Seal any leaks found if any
vacuum or exhaust pipeline connections have been disconnected.
Maintenance plan
WARNING:
If the turbo pump is removed from the T-Station 85 platform, it is important to retain and
reuse the same fixing screws. If any of these screws are lost or cannot be used, the
following type M5 x 12 mm CAP HD high tensile class 12.9 must be used. If this warning is
ignored and the turbo pump seizes, the stored energy in the turbo pump may cause some
or all of the screws to fail. This may result in the turbo pump being ejected from the T-
Station 85 base.
List of instruction manuals that state the minimum maintenance operations necessary to
maintain the T-Station 85 in normal use:
Diaphragm pump
XDD1
A746-02-885
Rotary vane pumps
E2M0.7 / E2M1.5
A371-32-880
Turbomolecular pumps
nEXT85
B8G0-00-880
More frequent maintenance may be necessary if the T-Station 85 has been used to pump
corrosive or abrasive gases and vapour. If necessary, adjust the maintenance plan according to
your experience.
