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 Edwards Publication Number P400-40-100 'Vacuum Pump and Vacuum System
Safety'.
Only Edwards engineers may install the dry pumping system. Users can be trained by Edwards to conduct the
tasks described in this manual, contact the 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) with
nitrogen for 15 minutes before starting installation work. Refer to Section 4.
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 ventilation extraction and secondary containment of oil and water
leaks. Any unintended overflows or spills 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 Publication Number P400-40-100 (Vacuum Pump and Vacuum System Safety) before pumping
hazardous materials. This publication is available on request: contact the supplier or Edwards.
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 system should not be operated with the Edwards panels removed.
