WARNING:
Obey the safety instructions in this section and take note of appropriate precautions.
Failure to do so may result in injury to people and damage to equipment.
WARNING:
The dry pumping system should not be operated with the enclosure panels removed.
WARNING:
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.
WARNING:
Do not expose any part of the human body to a vacuum as it can cause injury.
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
publication number P40040100 Vacuum Pump and Vacuum Systems.
▪ A suitably trained and supervised technician must install the dry pumping system.
Users can be trained by us to conduct the tasks described in this manual, contact
us or your local service centre 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
Maintenance
▪ 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 the risk of slips.
▪ Obey all national and local rules and safety regulations when installing the dry
pumping system. Consult our safety manual publication number P40040100
