Page 8: Installation
You must be able to purge with an inert gas when you shut down the pumping system to dilute dangerous gases to safe concentrations. Consult Edwards or your supplier if you are in doubt. If the EH pump is to be fitted in a new system, ensure that all preliminary pipelines have been installed and that a Safety suitable base for the EH pump has been prepared before you start installation. -
