1.1.1. GENERAL USE WARNINGS
WARNING
Before starting the boiler the User must
make sure that the First start-up certificate has the
stamp of the technical Support Centre proving the
testing and the first start-up of the boiler.
WARNING
To validate the warranty, the boiler must
be started by a technical Support Centre authorized
by RADIANT no later than 30 days from the date of
installation.
WARNING
In order to take advantage of the guarantee
provided by the manufacturer, the customer should
carefully and exclusively observe the instructions
given in the USER section of the manual.
ATTENTION
This machine may be used only for the
purpose for which it has been designed: heat water
to a temperature below boiling point at atmospheric
pressure. Any other use is considered wrong and
dangerous. The manufacturer is excluded from
any contractual or out of contract responsibility for
damage caused to people, animals or property due to
incorrect use.
DANGER
The boiler should not be used by persons
(including children) with reduced physical, sensory or
mental capacities or without suitable knowledge or
experience unless they are instructed on the device
use or monitored by a person responsible for their
safety.
DANGER
DO NOT obstruct the air vents of the
location in which the gas device is installed to prevent
the formation of toxic explosive mixes.
DANGER
If you sense a gas odour in the location in
which the boiler is installed, proceed as follows:
› DO NOT use electrical switches, the telephone or
any other device that might generate electrical
discharges or sparks;
› Immediately open all doors and windows to
create an air exchange that can quickly clean the
location;
› Close the gas valves;
› Request immediate intervention of qualified
staff.
DANGER
The use of the electrical power boiler
implies respecting some fundamental rules such as:
› DO NOT touch the device with wet and/or humid
parts and/or with bare feet;
› DO NOT pull the electrical cables;
› DO NOT leave the device exposed to atmospheric
agents (rain, sun, etc.) unless specifically
intended;
› in case of cable damage, turn off the device and

1.1.8. SYSTEM FILLING
To restore the water pressure inside the system
open the loading tap “R” (fig. 1) and make sure
using pressure gauge “M” (fig. 1), that the system
pressure reaches 1.2 bar (see fig. 2).
After performing this operation, make sure that the
loading tap “R” (fig. 1) is properly closed.
After the water pressure reset the boiler will
automatically perform a 2 minutes system relief
cycle. Throughout this function the display will
show the code “F33”. The boiler can work normally
only after completing the operation.
