1.3 ANTIFREEZE PROTECTION.

Minimum temperature -5°C. The hydronic unit
comes standard with an anti-freeze function that
activates the condensing unit when the temper-
ature of the water inside of it falls below 4°C.
In these conditions, the hydronic unit is protected
against freezing up to an ambient temperature
of -5℃.
Minimum temperature -15°C. In the event the
hydronic unit is installed in a place where the
temperature falls below -5°C, it is possible for
the appliance to freeze.
To prevent the risk of freezing follow the instruc-
tions below:
- protect the central heating circuit from freezing
by inserting a good-quality antifreeze liquid
into this circuit, which is specially suited for
central heating systems and which is manu-
facturer guaranteed not to cause damage to
the heat exchanger or other components of
the hydronic module. The antifreeze liquid
must not be harmful to one's health. The in-
structions of the manufacturer of this liquid
must be followed scrupulously regarding
the percentage necessary with respect to the
minimum temperature at which the system
must be kept. An aqueous solution must be
made with potential pollution class of water 2
(EN 1717:2002).

The materials used for the hydraulic circuits of
Immergas hydronic units resist ethylene and
propylene glycol based antifreeze liquids (if the
mixtures are prepared perfectly).
For life and possible disposal, follow the sup-
plier's instructions.
- Protect the domestic hot water circuit against
freezing by using an accessory that is supplied
on request (antifreeze kit) comprising two
electric heating elements, the relevant cables
and a control thermostat (carefully read the
installation instructions contained in the ac-
cessory kit pack).
In these conditions, the hydronic unit is protected
against freezing up to a temperature of -15°C.
Hydronic unit anti-freeze protection (both -5°C
and -15°C) is only ensured if:
- The hydronic unit and the condensing unit are
properly connected to each other and to the
electrical supply voltage circuits;
- The units are continuously powered;
- The units are not in "off " mode.
- The units are not in anomaly (parag. 2.5);
- The unit and/or kit essential components are not
faulty.
The warranty does not cover damage due to inter-
ruption of the electrical power supply and failure

to comply with that stated on the previous page.
N.B.: if the hydronic unit is installed in places
where the temperature drops below 0°C, the
domestic hot water connection pipes must be
insulated.
