5.6 Operation sequence
Close all vent valves in the high points of the unit hydraulic circuit
Close all drain valves in the low points of the unit hydraulic circuit:
•
Heat exchangers
•
Pumps
•
collectors
•
storage tank
1. Carefully wash the system with clean water: ll and drain the system several times.
2. Apply additives to prevent corrosion, fouling, formation of mud and algae.
3. Fill the plant
4. Vent the system
5. Execute leakage test.
6. Isolate the pipes to avoid heat dispersions and formation of condensate.
7. Leave various point of service free (wells, vent-holes etc).
Neglecting the washing will lead to several lter cleaning interventions and at worst cases can cause damages to the exchangers and the
other parts.
