Operation sequence
Before starting the unit pump :
1 Close all vent valves in the high points of the
unit hydraulic circuit.
2 Close all drain valves in the low points of the
unit hydraulic circuit
• Exchangers
• Pumps
• collectors
• storage tanks
3 Carefully wash the system with clean water:
use the bypass to exclude the exchanger from
the flow (diagram on previous page) fill and
drain the system several times.
4 fill and drain the system several times.
5 Apply additives to prevent corrosion, fouling,
formation of mud and algae.
6 Fill the plant
Do not use the unit pump
7 Execute leakage test.
8 Isolate the pipes to avoid heat dispersions and
formation of condensate.
9 Leave various point of service free (wells, vent-
holes etc).
Neglecting the washing will lead to several filter
cleaning interventions and at worst cases can
cause damages to the exchangers and the other
parts.
