10.4 Test unit operation
The best way to test the operation of the pressurisation unit is to drain some water from the sytem,
creating a pressure loss, allowing the pressure to drop slowly. Once the pressure falls below the
minimum pressure level setting ([COLD FILL] – [DIFFERENTIAL]) the valves should be activated. As
soon as the valves activate, close the drain point and allow the system pressure to rise. Once the
[COLD FILL] pressure is reached, the valves should be deactivated and the internal air break vents
through the drain connection.
An digital service log can be filled out to store the information at time of Maintenance.
For digital service log, see link or QR in chapter 10: ''Maintenance intervals''.
11 Decommissioning / Dismantling
At the end of the of the service life or at planned shut-down of the equipment, please refer to
chapter: 9.1 “Shut-down procedure” and follow the steps. The unit is separated from the power
supply. The hydraulic system connection and top-up connection should be closed off.
Water areas should first be made pressure-less and drained according with the
applicable local rules. This water may be chemically treated, contain antifreeze or
other additives.
Further processing of the construction parts should be carried out in agreement with
the required waste management service provider.
