Safety
The dynamic seals and O-rings used in this pump are made from fluorinated materials. Fluorinated materials are safe
in normal use but can decompose into very dangerous materials (which may include hydrofluoric acid) if they are
heated to 210 °C and above.
The pump may have overheated if it was misused or if it was in a fire. If the pump has overheated, take extreme care
to avoid skin contact with any part of the pump and to avoid inhalation of vapours from the pump. Health and Safety
Data sheets for fluorinated materials used in the pump are available on request: contact your supplier or Edwards.
WARNING
Do not touch or inhale the thermal breakdown products of fluorinated materials which may be
present if the pump has been heated to 210 °C and above. These breakdown products are very
dangerous. Some of the seals in the pump are made from fluorinated materials.
