7.2 Mechanical Installation
Once the generator has been located into position, install the ball valves and the pipework ready for
connection to the buffer vessel and compressed air supply.
The diameter of the pipes must be sufficient to allow unrestricted inlet air supply to the generator and nitrogen
supply to the applications shown in the table below.
It is recommended that the system be protected with suitably rated pressure relief valves
upstream of the generator.
Ensure that all piping materials are suitable for the application, clean and debris free. All outlet piping must be
solid and non-porous to minimize the ingress of oxygen.
When routing the pipes ensure that they are adequately supported to prevent unnecessary strain which can
lead to damage and leaks in the system.
The nitrogen buffer vessel must be rated to at least the maximum operating pressure of the generator and
must be fitted with suitable valving pressure gauge and pressure relief valve.
