3 Installation
3.1 Safety
You must ensure that the XDS pump is suitable for your application. If you have any doubt about the suitability of the
XDS pump 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).
The installation of the XDS pump must be performed by a suitably trained and supervised technician. 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.
Wear the appropriate safety clothing when you come into contact with contaminated components. Dismantle
and clean contaminated components inside a fume cupboard.
Vent and purge your vacuum system before you start installation work.
Ensure that the installation technician is familiar with the safety procedures which relate to the products
handled by the pumping system.
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:
Use a suitable valve to isolate the pump from your vacuum system if you need to allow the pump to warm up before
pumping condensable vapours or if you need to maintain vacuum when the pump is switched off.
Avoid high levels of heat input into the pump from the process gases, otherwise the pump may overheat and seize,
and cause the motor thermal overload device to open.
If you use the pump in a high ambient temperature and have a high gas throughput, the temperature of the pump
body may exceed 100 °C and you must fit suitable guards to prevent contact with hot surfaces.
Make sure that the exhaust pipeline cannot become blocked. If you have an exhaust isolation valve, make sure that
you cannot operate the pump with the valve closed.
3.3 Unpack and inspect
Remove all packing materials, remove the pump from its packing box, remove the protective covers from the inlet
and outlet ports and inspect the pump. If the pump is damaged, notify your supplier and the carrier in writing; state
the item number of the pump together with your order number and your supplier’s invoice number. Retain all the
packing materials for inspection. Do not use the pump if it is damaged.
If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as
described in Section 6.1.
The Edwards XDS dry pump is not recommended for pumping hazardous substances.
