System design
WARNING
You must incorporate the design features detailed below in your system. If you do not,
you can cause injury to people and damage to your equipment.
3.2.1
Inlet-purge
To ensure that your vacuum system cannot be over-pressured by the nitrogen supply to the
inlet-purge, you must design your vacuum and control systems so that :
•
the parts of your vacuum system which are not suitable for positive pressures are isolated
when the pump is not in use and the inlet-purge nitrogen supply is switched on
or :
•
the electrical supply to the inlet-purge solenoid-valve (through the Gas Module) is
connected so that the valve is closed when the QDP pump is switched off.
