regulations of the floor manufacturer!

4.6 FUNCTIONING ANOMALIES
When there is a functioning anomaly, an
alarm appears on the display and the blue
luminous bar becomes red.
Descriptions of the anomalies with relative
alarms and solutions are given below:
– LOW WATER PRESSURE ANOMALY
ALARM 02 (fig. 23/a)
If the pressure detected by the transdu-
cer is lower than 0.5 bar, the boiler
stops and the display shows the alarm
"ALL 02".
Bring the pressure back to normal by
acting on the loading knob. Lower the
knob and turn it anti-clockwise to open
until the pressure indicated by the
display is between 1 and 1.5 bars.
WHEN FILLING HAS BEEN COMPLETED,
CLOSE THE KNOB BY TURNING IT
CLOCKWISE.
If the load procedure has to be repea-
ted several times, it is advisable to
check that the seal of the heating cir-
cuit is intact (check that there are no
leaks).
