2.7 BOILER SHUTDOWN
Switch the boiler off by putting it in “off” mode,
disconnect the onmipolar switch outside of the
boiler and close the gas cock upstream from the
appliance. Never leave the boiler switched on if
left unused for prolonged periods.
2.8 RESTORING CENTRAL HEATING
SYSTEM PRESSURE.
Periodically check the system water pressure.
The boiler pressure gauge should read a pressure
between 1 and 1.2 bar.
If the pressure falls below 1 bar (with the circuit
cold) restore normal pressure via the valve located
at the bottom of the boiler (Fig. 1-3).
N.B.: close the cock after the operation.
If pressure values reach around 3 bar the safety
valve may be activated.
In this case, remove water from an air vent valve
of a radiator until reaching pressure of 1 bar, or
ask for assistance from professionally qualified
personnel.
In the event of frequent pressure drops, contact
qualified staff for assistance to eliminate the
possible system leakage.
2.9 SYSTEM DRAINING.
To drain the boiler, use the special draining
valve (Fig. 1-3).
Before draining, ensure that the filling cock is
closed.
2.10 ANTI-FREEZE PROTECTION.
The “Victrix 12X-20X TT 2 ErP” series boiler
features an antifreeze function that lights the
burner automatically when the temperature falls
below 4 ° C (standard protection down to min.
temperature of -5 ° C). All information relative to
the anti-freeze protection is stated in Par. 1.3. In
order to guarantee the integrity of the appliance
and the domestic hot water heating system in
zones where the temperature falls below zero,
we recommend the central heating system is
protected using anti-freeze liquid and installation
of the Immergas Anti-freeze Kit in the boiler. In
the case of prolonged inactivity (second case),
we also recommend that:
- disconnect the electric power supply;
- the central heating circuit and boiler domestic
hot water circuit must be drained. In systems
that are drained frequently, filling must be car-
ried out with suitably treated water to eliminate
hardness that can cause lime-scale.
2.6 INFORMATION MENU.
By pressing the "Info" button (5), the “Infor-
mation menu” is activated for at least 1 second,
displaying some boiler operating parameters.

d 09
Displays the list of the last five anomalies.
(to scroll the list, turn the CH temperature selector (4))
d 1.0 Anomaly list reset. Once “d 1.0” is displayed, press the Reset button; deletion is confirmed via the “88” symbols flashing for two seconds.
d 1.1 Displays the temperature read on the safety flow probe
d 1.2 Displays the pump operating speed
d 1.3 Not used

Press the "Info" button (5) to scroll the various
parameters.
To exit the menu, press the “Info” button (5) up
to the end of the list, or by pressing the “Reset”
button (2) or by waiting for 15 minutes.
With the menu active, the indicator (14) will
alternately show the indication of the parameter
via the letter “d” plus the number of the param-
eter that is being displayed and the value of the
parameter itself.
2.11 CASE CLEANING.
Use damp cloths and neutral detergent to clean
the boiler casing. Never use abrasive or powder
detergents.
2.12 DECOMMISSIONING.
In the event of permanent shutdown of the boiler,
contact professional staff for the procedures and
ensure that the electrical, water and gas supply
lines are shut off and disconnected.
