2.7 SWITCHING OFF THE HYDRONIC
MODULE.
Switch off the hydronic module, putting it in
"off " mode. Switch off the omni-polar switch
outside the unit. Never leave the unit powered if
left unused for prolonged periods.
2.8 RESTORING CENTRAL HEATING
SYSTEM PRESSURE.
Periodically check the system water pressure.
The hydronic module pressure gauge must show
a value between 1 and 1.2 bar.
If the pressure is less than 1 bar (with the system
cold), you must restore it using the cock located at
the bottom of the unit (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.

SYSTEM DRAINING.

To drain the hydronic mdule, use the special
drain tap (Fig. 1-3).
Before draining, ensure that the filling cock is
closed.

This function can only be activated if CAR
is available
Activating the function allows you to disable condensing
unit operation during the time slot set in the U 12 and
U 13 parameters.
Make sure the additional power sources needed to meet
potential requirements that may present themselves
during active operation are available (e.g. additional
resistances)

2.10 ANTI-FREEZE PROTECTION.

The hydronic module has an anti-freeze function
that automatically switches on the condensing
unit when the temperature drops below 4°C
(standard protection up to a minimum temper-
ature 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
areas where the temperature drops below zero,
we recommend protecting the central heating
system using anti-freeze liquid and installing the
Immergas Anti-freeze Kit in the hydronic mod-
ule. In the case of prolonged inactivity (second
case), we also recommend that:
- disconnect the electric power supply;
- completely empty the central heating circuit
and the hydronic module domestic hot water
circuit. In systems that are drained frequently,
filling must be carried out with suitably treated
water to eliminate hardness that can cause lime-
scale.

2.11 CASE CLEANING.

Use damp cloths and neutral detergent to clean
the hydronic module casing. Never use abrasive
or powder detergents.

2.12 DECOMMISSIONING.

Should the system be shut down permanently,
have professional staff carry out the procedures,
making sure that the electrical and water supply
lines have been previously shut off.
