1.2.8 Shutdown due to insufficient water pressure
In the event of boiler shutdown due to water pressure switch inter-
vention, no. 4
red light starts blinking, signalling insufficient water
pressure in the CH system.
In order to restore water pressure, proceed as follows (see pic. 4):
- open the loading tap by rotating it counter-clockwise in order to
allow water in the boiler, and keep it open until the water pressure
gauge (14 in pic.1) displays a pressure of 1-1,3 bars; close the
loading tap by rotating it clockwise.
WARNING
Once the loading procedure is completed, fully close the inlet
tap. Should the tap not be properly closed, as pressure increa-
ses, boiler CH safety valve may open and water flow out.
Should boiler frequently shut down due to insufficient water pres
-
sure, have it serviced by an Authorized Service Centre or qua-
lified personnel.
1.2.9 Shutdown due to malfunction of temperature probes
Should the burner shut down due to malfunctioning of temperature
probes, the following lights turn on and flash:
- red light 5 (pic.1) for probe 1 (CH)
- red light 7 for probe 2 (water tank)
- red light 8 for probe 3 (plate heat exchanger)
In this instance, contact an Authorized Service Centre or qualified
personnel for service.
1.3 Maintenance
The user may only clean the external boiler casing, by means
of commonly marketed household products.
Do not use water!
As provided by law, the boiler is to be serviced once a year. Correct
maintenance ensures boiler to function efficiently, environmentally
friendly, preventing any danger to people, animals or property.
Only qualified personnel are lawfully allowed to service the boiler.
The manufacturer recommends Customers to contact an Authori-
zed Service Centre for maintenance and repairs.
1.4 Information for the User
The user may only access boiler parts that can be reached
without using technical equipment and/or tools: the user is
not authorized to remove boiler housing and operate on any
internal part. No one, including qualified personnel, is authori
-
zed to modify the boiler.
The manufacturer shall not be held responsible for damage to
people, animals, or property, due to tampering with the boiler
or improper intervention.
Should the boiler be left inactive for a long time and power
main supply disconnected, it might be necessary to unlock
the pump.
Pump service includes boiler housing dismounting and ac-
cess to boiler internal parts, therefore only qualified personnel
may perform it.
Pump blockage may be avoided by mixing to water, filming
additives suitable for multi-metal systems.
CH system can be properly protected from frost by using spe-
cific anti-frost additives suitable for multi-metal systems. Do
not use automotive products and verify the additive efficiency
over time.
The boiler is equipped with a thermometer allowing for water
temperature verification.
