Installation
3.1
Safety
Ensure that the pump is suitable for the application. If there is any doubt, refer to the Edwards guidelines in
the Vacuum Pump and Vacuum Systems Safety manual. (See Associated publications at the end of the
Content list.)
A suitably trained and supervised technician must install the pump.
Wear the appropriate safety clothing when coming into contact with contaminated components.
Vent and purge the vacuum system before starting installation work.
Ensure that the installation technician is familiar with the safety procedures which relate to the pump oil
and the products handled by the E-LAB 2. Take suitable precautions to avoid the inhalation of oil mist and
excessive skin contact with pump oil, as prolonged exposure can be harmful.
Disconnect other components in the pumping system from the electrical supply so that they cannot be
operated accidentally.
Ensure that the inlet catchpot, outlet oil mist filter and the gas ballast oil return kit are correctly fitted as
described in the following sections.
Safely route any cables and pipes to prevent a trip hazard.
3.2
System design considerations
Consider the following points when designing the pumping system:
Use a suitable valve to isolate the pump from the vacuum system to allow the pump to warm up before
pumping condensable vapours or to maintain vacuum when the pump is switched off.
Avoid high levels of heat input to the pump from the process gases, otherwise the pump may overheat and
seize.
If the pump is used in a high ambient temperature environment and has a high gas throughput, the
temperature of the pump body may exceed 70 ºC. Fit suitable guards to prevent contact with hot surfaces.
Make sure that the exhaust pipeline cannot become blocked. If the system has an exhaust isolation valve,
make sure that the pump cannot operate with the valve closed.
WARNING
The E-LAB 2 is not recommended for pumping hazardous substances.
WARNING
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.
WARNING
Do not expose any part of the human body to vacuum as it can cause injury.
