3 Installation
3.1 Safety
Cooling water must be provided commensurate with environmental conditions (humidity and temperature) such
that the dew point is not reached.
z Ensure that the EPX pump is suitable for your application. The EPX L series of pumps are designed for
semiconductor loadlock or transfer pumping applications, or clean general vacuum applications. The EPX N
series of pumps are designed for the light-duty applications detailed in Figure 1. Contact Edwards or your
supplier if you want to use the EPX pump on any other application. Incorrect use of the EPX pump may
invalidate your warranty.
z Ensure that you comply with all local and national safety requirements during installation.
z Ensure that the installation technician is familiar with the safety procedures which relate to the products
pumped. Wear the appropriate safety-clothing when you come into contact with contaminated components.
Dismantle and clean contaminated foreline components inside a fume-cupboard. The EPX pump should NOT
be dismantled under any circumstances.
z Vent and purge the process system before you start installation work.
z Disconnect the other components in the process system from the electrical supply so that they cannot be
operated accidentally.
Further details are available from the Edwards publication ‘Vacuum pump and Vacuum System Safety’, part no.
