Safety information
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.
The XDS100B Scroll Booster is designed to require little user maintenance. Observe the following
guidelines when carrying out maintenance on your pump:
z
Ensure that maintenance is done by a suitably trained and supervised technician. Obey
your local and national safety requirements.

.
z
Allow the pump to cool before you start maintenance work.
z
Do not re-use internal O-rings.
WARNING
Disconnect the pump and other components from the electrical supply so that they cannot be
operated accidentally. Wait one minute for capacitor discharge after disconnecting the power
supply before working on the pump.
WARNING
The XDS100B must be isolated from its backing pump before maintenance can begin. If the booster
backing pump is connected and operational the XDS100B scrolls will rotate.
WARNING
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 that you take
adequate precautions to protect people from the effects of dangerous substances if contamination
has occurred.
WARNING
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 ºC 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 260 ºC 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.
