5 Maintenance
5.1 Safety
z
Ensure that maintenance is done by a suitably trained and supervised technician. Obey your local and
national safety requirements
z
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
z
Check that all the required parts are available and of the correct type before you start work
z
Isolate the pump and other components from the electrical supply so that they cannot be operated
accidentally
z
Allow the pump to cool to a safe temperature before you start maintenance work
z
Do not re-use 'O' rings and seals if they are damaged
z
After maintenance is completed, recheck the direction of pump rotation if the electrical supply has been
disconnected
z
Do not touch or inhale the thermal breakdown products of fluorinated materials which may be present if the
pump has been heated to 310°C and above. Fluorinated materials are safe in normal use but can decompose
into very dangerous substances (which may include hydrofluoric acid) if they are heated to 310°C and above.
The pump may have overheated if it was misused or if it was in a fire. Health and Safety Data sheets for
fluorinated materials used in the pump are available on request; contact your supplier or Edwards
z
Leak-test the system after maintenance work is complete if you have connected or disconnected any vacuum
or exhaust joints; seal any leaks found.
z
The pump and the pump-oil will be contaminated with the process chemicals that have been pumped during
operation. Ensure that the pump is decontaminated before maintenance and that you take adequate
precautions to protect people from the effects of dangerous substances if contamination has occurred.
WARNING
Obey the safety instructions given below and take note of appropriate precautions. If you do not,
you can cause injury to people and damage to equipment.
