Installation
3.1
Safety
You must ensure that the XDS100B booster is suitable for your application. If you have any doubt about the suitability
of the XDS100B booster for your application, refer to the Edwards guidelines on vacuum pump and vacuum system
safety (see associated publications at the end of the contents list at the front of this manual).
A suitably trained and supervised technician must perform the installation of the XDS100B Booster. Obey the safety
instructions listed below when you install the XDS pump, especially when you connect the pump into an existing
system. Details of the specific safety precautions are given at the appropriate point in the instructions.
z
Wear the appropriate safety clothing when you come into contact with contaminated components. Dismantle
and clean contaminated components inside a fume cupboard.
z
Vent and purge your vacuum system before you start installation work.
z
Ensure that the installation technician is familiar with the safety procedures that relate to the products
handled by the pumping system.
z
Disconnect the other components in the pumping system from the electrical supply so that they cannot be
operated accidentally.
3.2
System design considerations
Consider the following points when you design your pumping system:
Avoid high levels of heat input into the pump from the process gases, otherwise the pump may overheat, and cause
the thermal overload device to open.
Make sure that the foreline from the booster to the backing pump and the exhaust pipeline from the backing pump
outlet cannot become blocked. If you have an exhaust isolation valve, make sure that you cannot operate the pump
with the valve closed. Refer to
.
Provide for a purge of inert gas when you shut down the pumping system, to dilute dangerous gases to safe
concentrations.
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.
WARNING
Prevent any part of the human body coming into contact with the vacuum.
WARNING
The Edwards XDS100B booster is not recommended for pumping explosive gases or hazardous
substances.
