Introduction

1Introduction
1.1 Scope and definitions
This manual provides installation, operation and maintenance instructions for the GXS vacuum pump accessories and
should be used in conjunction with the GXS Dry Pumping System Instruction Manual - M588-00-880. You must use the
GXS vacuum pumping system accessories as specified in this manual.
Read this manual and the GXS Dry Pumping System Instruction Manual - M588-00-880 before you install or use the GXS
vacuum pumping system accessories. Important safety information is highlighted as WARNING and CAUTION
instructions; you must obey these instructions. The use of WARNINGS and CAUTIONS is defined below.
CAUTION
Cautions are given where failure to observe the instruction could result in damage to the equipment, associated
equipment and process.
The units used throughout this manual conform to the SI international system of measurement.
1.2 Flammable / pyrophoric materials
When flammable or pyrophoric materials are present within the pump there may be additional risks that the user is
responsible for assessing and managing as part of the entire process system installation. The severity of the risks and
the necessary control measures will depend largely on whether the process system exhaust is in the flammable
region, if this is part of normal operation, or if it might only occur under rare conditions. The additional risks arise
because all dry pumps must be considered a potential source of ignition due to the heat of compression, or possibly
friction. If ignition occurs then the following may happen:
High pressures could occur within the pump and may not be contained.
A flame front could travel back up the foreline.
A flame front could travel downstream from the exhaust of the pump.
Industry best practice suggests that the following measures will reduce the risks of pumping flammable mixtures and
pyrophoric materials, but it is the responsibility of the user to carry out a risk assessment and take appropriate
measures:
Do not allow air to enter the equipment.
Ensure that the system is leak tight.
Ensure that gases in the pump do not enter the flammable range. This may be achieved by diluting gases in
the pump by supplying sufficient inert gas purge. For example, dilution with nitrogen to below one quarter
Lower Explosive Limit (LEL) or, if that is not practical, to below 60 % Limiting Oxidant Concentration (LOC).
WARNING
Warnings are given where failure to observe the instruction could result in injury or death to
people.
WARNING
You must obey the instructions and take note of any precautions given below to ensure that
pumped gases do not enter their flammable ranges.

Introduction
The gas module supplied with the pump is not intended to perform a safety function. Users may need to
consider adding appropriate measures to monitor the flow of purge gas, for example external sensors.
Systems that are fitted with the light duty gas module must not be used on applications pumping flammable
or pyrophoric materials.
For further information please refer to Publication Number P400-40-100, Applications Note 'Pumping Flammable
Gases' P411-00-090 or contact Edwards.
1.3 Safety and maintenance frequency
Ensure that the maintenance technician is familiar with the safety procedures which relate to the products
pumped.
Allow the pumps to cool to a safe temperature before you fit lifting eye bolts or start maintenance work.
Vent and purge the dry pumping system before you start any maintenance work.
Isolate the dry pumping system and other components in the process system from the electrical supply so
that they cannot be operated accidentally. Note that the emergency stop switch on the dry pumping system
is not an electrical isolator.
Wait for at least four minutes after you have switched off the electrical supply before you touch any
electrical component on the dry pumping system.
Route and secure cables, hoses and pipelines during maintenance to avoid possible risk of trips or
entrapment.
WARNING
Obey the safety instructions given below and take the appropriate precautions. If you do not, you
can cause injury to people and damage to equipment.
WARNING
Electrical, purge gas and water supplies are all potentially hazardous energy sources. Before
carrying out any maintenance the supply of these sources should be locked and tagged out.
WARNING
Personal protective equipment should be checked and used as specified by its supplier. Hazardous
chemicals that have been pumped are located within the pumps and piping. Use of suitable
protective gloves and clothing along with a respirator is recommended if contact with substances
is anticipated. Particular caution should be exercised when working with fluorinated materials
which may have been exposed to temperatures greater than 260 °C. Refer to Edwards Material
Safety Data Sheets for detailed information.
