3.2 Mechanical Installation

A Fit one of the 1/2Ýball valves supplied to the compressed air inlet port on the generator and attach the compressed air supply to this ball
valve. Ensure that the valve is in the closed position.
B Fit another of the 1/2Ýball valves supplied to the port marked "To Buffer vessel". Install 1/2" NB / 16mm ID piping between the ball valve and
the buffer vessel inlet port. It is recommended that a ball valve (not supplied) be installed at the inlet to the buffer vessel to allow it to be
isolated during maintenance.
C Fit the remaining 1/2Ýball valve to the port marked "From Buffer vessel". Install 1/2" NB / 16mm ID piping between the ball valve and the
outlet port of the buffer vessel. The AR010 dust filter provided should be installed in this line. Follow the installation instructions provided
with the filter taking note of the direction of flow. It is recommended that a ball valve (not supplied) be installed at the outlet of the buffer
vessel to allow it to be isolated during maintenance.
D Fit the 3-way ball valve supplied to the port marked "Nitrogen Outlet". Connect this ball valve to the application using 1/2" NB / 16mm ID
piping.This piping must be solid and non-porous to minimise the ingress of oxygen.
Note. The nitrogen buffer vessel must be rated to at least the maximum operating pressure of the generator and must be fitted with a suitable
pressure gauge and pressure relief valve.

It is recommended that the system be protected with suitably rated pressure relief valves upstream of the generator.
