(3-g.1a)to
(OFF).
Then,closethegastappresentonthesystem.Inthiscase,anti-

frost.
4A CONTROLS
Atthebeginningofthe heating season, and occasionally during
use,makesurethehydrometer-thermohydrometerindicatescold
systempressurevaluesbetween0.6and1.5bar:thisavoidssys-
temnoiselevelsduetothepresenceofair.Incaseofinsufcient
water circulation, the boiler will switch off. Under no circumstances,
waterpressuremustbebelow0.5bar(redeld).
Ifthisconditionischecked,itisnecessarytorestorewaterpres-
sure in the boiler proceeding as follows:
-setthemodeselector(3-g.1a)to
(OFF)
-turnonthellingtap(Lg.13)untilthepressurevalueisbe-
tween 1 and 1.5 bar.
Carefullyclosethe tap. Replace the mode selectorontheinitial
position. If pressure drop is frequent, contact the Technical Assis-
tance Service.

Position the function selector to
(OFF),wait5-6secondsthen
set it to the required position
(summermode)or (winter

.
Checkthepressurevalueindicatedbythewatergauge:
if it is less than 0.3 bar, position the function selector to (OFF)
andadjust the lling tap (Lg.13)until the pressure reaches a
value between 1 and 1.5 bar.
Then position the mode selector to the desired position (sum-
mer)or
(winter).
If pressure drops are frequent, request the intervention of the
Technical Assistance Service.
Fault A 06
Theboileroperatesnormallybutcannotreliablymaintainacon-
stant domestic hot water temperature, which remains set at around
50°C. Contact the Technical Assistance Centre.
