CHECKS AND
MAINTENANCE
- Check connection to a 230V-50Hz power
mains via an omni-polar disconnector (magne-
tothermal circuit breaker), correct L-N polarity
and the earthing connection;
- check that the magnetothermal circuit breaker
is working properly;
- make sure the central heating system is filled
with water and that the pressure gauge indicates
a pressure of 1-1.2 bar;
- make sure that the air valve cap (if present)
is open and that the system is appropriately
de-aerated;
- check the activation of the main switch located
upstream of the appliance;
- check the sealing efficiency of water circuits;
- check the correlation between the electric and
hydraulic connections;
- (only for DIM H-LT or H-2LT) with request
for heat in the mixed zones, check the correct
opening and closure of the mixing valve,
opening the latter to check the system safety
thermostat intervention (the boiler flow tem-
perature must be set over 60 °C).
Even if just one single safety check provides a
negative result, do not commission the system.
