Do not weld the system pipe with the Victaulic connection joint attached.
The rubber gasket might be irreparably damaged.

4.9 Water filter
Use a filter with 1,6 mm degree of filtration
It must be installed immediately in the water input of the unit, in a position that is easily accessible for cleaning.
The filter never should be removed, this operation invalidates the guaranty.
4.10 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
•
free-cooling coil
1. Carefully wash the system with clean water: fill and drain the system several times.
2. Apply additives to prevent corrosion, fouling, formation of mud and algae.
3. Fill the plant
4. Execute leakage test.
5. Isolate the pipes to avoid heat dispersions and formation of condensate.
6. 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.
