ONTROL AND
MAINTENANCE.
- Using an omnipolar disconnector, check connection to
230V-50Hz mains power supply, correct L-N polarity and the
earthing connection;
- make sure the central heating system is filled with water and that
the manometer of the Internal Unit indicates a pressure of 1÷1.2
bar;
- make sure that the air vent valve cap (if present) is open and that
the system is well deaerated;
- check tightness of water circuits;
- check the correlation between the electric and hydraulic con-
nections;
- with request for heat in TA zone 1 and TA zone 2, check that the
mixing valve opens and closes properly; open the latter to check
the intervention of the system safety thermostat (the Internal
Unit flow temperature must be set over 60 °C).
Even if just one single safety check provides a negative result, do
not commission the system.
N.B.: the 16 l DHW (Domestic hot water) expansion vessel is
connected to the hydronic unit via a flexible hose; in the event
of maintenance it is possible to temporarily move the vessel by
unscrewing the lock nut that fastens it to the relative supporting
bracket.
