Do not weld the system pipe with the Victaulic connection joint attached.
The rubber gasket might be irreparably damaged.
4.8 Water filter
Use fil
t
er with mesh pitch:
1,6
mm
It must be installed immediately in the water input of the unit, in a position that is easily accessible for cleaning.
The fil
t
er never should be removed, this operation invalidates the guaranty.
4.9 Flow Switch
The fl
o
w switch must be present to ensure shutdown of the unit if water is not circulating.
It has to be installed in a duct rectilinear part, not in proximity of curves that cause turbulences.
Electrically connect the fl
w switch at the inlet arranged on the XC terminal block.
The fl
w switch must be set to the minimum reachable fl
w rate.

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 d ain 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 fil er cleaning interventions and at worst cases can cause damages to the exchangers and the
other parts.
