Introduction
It is the responsibility of the customer to ensure the stability of the system and the correct application of all electrical
and vacuum connections once the system is installed on the application. It is also the responsibility of the customer
to ensure that no service connections form slip or trip hazards on the installed system.
There is no inlet screen fitted to the end of the cartridge pump and the blades of the turbo pump are visible and
accessible through the pump envelope at this point. The blades present a rotational safety hazard when the pump is
operational and a sharp-edged hazard when the pump is stationary. Care must be taken to avoid foreign objects
entering the pump when installing equipment to the chambers. The EXT70/70/200H system should only be operated
when rigidly mounted within the specially designed chamber and connected to a vacuum system.
The weight of the EXT70/70/200H cartridge pump, complete with EXDC160 controller, is approximately 8kg.
Appropriate handling precautions should be taken when manoeuvring the pump into the system. Appropriate nitrile
or latex gloves should be worn at all times while handling the cartridge pump to prevent contamination of the vacuum
parts.
WARNING
Under no circumstances should the pump be run other than when installed in the Edwards
approved sealed chamber.
