5.1 Safety information
External surfaces of the pump should be cleaned using warm soapy water. Care must be taken with solvent-
based cleaning fluids as they may remove important information from the product labels.
The pump is designed to require little user maintenance. Observe the following guidelines when carrying out
maintenance on the pump:
Ensure the maintenance is done by a suitably trained and supervised technician. Obey local and national
safety requirements.
Ensure the maintenance technician is familiar with the safety procedures which relate to the products
processed by the pumping system.
Check that all the required parts are available and are of the correct type before starting work.
Isolate the pump and other components from the electrical supply to prevent accidental operation.
Allow the pump to cool for at least 3 hours before starting maintenance work.
Obey the safety instructions in this section and take note of appropriate precautions. Failure to
observe these instructions may result in injury to people and damage to equipment.
In order to maintain the ATEX certification, all maintenance work has to be carried
out in accordance with this nXDS instruction manual, the nXDS Replacement Tip Seal
manual and the nXDS maintenance manual, using only genuine Edwards spare parts.
Disconnect the pump and other components from the electrical supply to prevent accidental
operation.
The pump may be contaminated with the process chemicals that have been pumped during
operation. If so, ensure that the pump is decontaminated before maintenance and adequate
precautions taken to protect people from the effects of dangerous substances if contamination has
occurred.
Do not touch or inhale the thermal breakdown products of fluorinated materials which may be
present in the pump if the pump has been heated to 260 °C and above. Fluorinated materials are
safe in normal use but can decompose into very dangerous substances (which may include
hydrofluoric acid) if heated to 260 °C and above. The pump may have overheated if it was misused
or if it was in a fire. Safety Data Sheets for fluorinated materials used in the pump are available on
request; contact the supplier or Edwards.
