can cause injury to people and damage to equipment.
The system should not be operated with the Edwards enclosure panels removed.
Potential hazards on the dry pumping system include electricity, hot surfaces, process chemicals, Fomblin oil,
nitrogen and water under pressure.
Detailed safety information is given in
Safety' (publication number P400-40-100).
Only Edwards trained engineers may 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

you are ready to connect the dry pumping system to your vacuum or exhaust-extraction system. Do not
operate the dry pumping system unless the inlet and exhaust are connected to your vacuum and exhaust-
extraction system.
Vent and purge the process system (if the dry pumping system is to replace an existing pumping system) with

nitrogen for 15 minutes before you start installation work. Refer to
Disconnect the other components in the process system from the electrical supply so that they cannot be

operated accidentally.
Electrical, nitrogen 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.
Route and secure cables, hoses and pipework during installation to avoid possible trip hazards.

The pump system includes provision for secondary containment of oil and water leaks. Any unintended

overflows or spills must be removed immediately to avoid risk of slips.
