- COMMISSIONING
3.1 - Installation
Install the appliance on a horizontal and stable surface.
The environment must be clean and free from dust.
Avoid locations that would expose the appliance to direct sunlight or draughts. Unpack
and remove the protective packaging from the appliance and its accessories.
Check the equipment and ensure it suffered no damage during transport.
Check the delivery note and make sure all accessories are present.
Check that the electrical specifications marked on the manufacturer’s plate are the same
as those that will be used. Check that the supply line is protected by fuses and grounded
(green/yellow wire).
An appliance with traces of impacts or apparent defects after transport or
unpacking must not be commissioned.
To avoid risks of condensation, the appliance must be left at room temperature for
several hours before it is powered on.
3.2 - Appliance connections
Depending on the desired use, the appliance must be connected to a source of nitrogen
supplying a maximum pressure of 2.0 bar (200 KPa) and to an air source of maximum
pressure 2.0 Bar (200 KPa). In order to obtain a stable flow rate during the test, the gas
must be supplied through a pressure relief device to stabilize the upstream pressure.
During the first test, which must be a no-load test (without samples), it is
vital to check the value of the gas flows and to adjust these depending
on the upstream gas pressure.
For guidance, for a flow rate of 150 ml/min, the flow meter should be set
to 20.62 mm and for a flow rate of 600 ml/min, at 58.20 mm. Always
refer to the abacus received with the appliance.
