3 Installation
Potential hazards on the dry pumping system include electricity, hot surfaces, process chemicals, lubricating oil,
purge gas and water under pressure.
Detailed safety information is given in Section 4 and Edwards Safety Manual Publication Number P400-40-100 Vacuum
Pump and Vacuum Systems.
A suitably trained and supervised technician must install the dry pumping system. Users can be trained by
Edwards to conduct the tasks described in this manual, contact your local service centre or Edwards for more
information.
Do not remove the temporary cover or blanking plate from the dry pumping system inlet and exhaust until
ready to connect the dry pumping system to the vacuum or exhaust extraction system. Do not operate the
dry pumping system unless the inlet and exhaust are connected to the vacuum and exhaust extraction
system.
Vent and purge the process system (if the dry pumping system is to replace an existing pumping system)
for 15 minutes before starting installation work. Refer to Section 5.
Disconnect the other components in the process system from the electrical supply so that they cannot be
operated accidentally.
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.
Any unintended overflows or spills of oil or water must be removed immediately to avoid risk of slips.
Obey all national and local rules and safety regulations when installing the dry pumping system. Consult
Edwards Safety Manual Publication Number P400-40-100 Vacuum Pump and Vacuum Systems before pumping
hazardous materials. This publication is available on request: contact your supplier or Edwards.
Route and secure cables, hoses and pipework during installation to avoid possible risk of trips.
Before locating the dry pumping system, ensure that the installation area is clean and free from debris and
contamination (such as oil).
In order for the dry pumping system to perform to specification, appropriate facilities must be provided as detailed
in this manual.
Obey the safety instructions in this section and take note of appropriate precautions. Failure to
observe these instructions may result in injury to people and damage to equipment.
The dry pumping system should not be operated with the enclosure panels removed.
The dry pumping system contains electrolytic capacitors which may emit dangerous fumes under
certain fault conditions. Ensure the dry pumping system is installed in a well-ventilated area.
