Flushing and air-purging
When filling water, the following start-up procedure should be followed.
1. All system components and pipes must be tested for the presence of leaks.
2. Preparation of a make-up water assembly or flushing unit is recommended for installation and service.
3. Before connecting pipes to the hydro unit, flush water pipes clean to remove contaminants during hours using a flushing
unit or tap water pressure if it is adequate (at 2 to 3 bar)
4. Fill water into the hydro unit by opening service valves.
5. Purge the air. (Fill with a flushing unit with sufficient capacity: avoid aerating the water)
6. Circulate for long enough to ensure that all air has been bled from the complete water piping system.
• After installations, commissioning should be performed by qualified representatives.
Unless flushing and air-purging works are performed adequately, it might result in malfunctions.
