Antifreeze Protection - Immergas MAGIS PRO 12 V2 Instructions And Recommendations

1.5

ANTIFREEZE PROTECTION

Minimum temperature 0°C
In these conditions, the indoor unit is protected against freezing up to an ambient temperature of 0°C.
If the indoor unit is installed in a place where the temperature drops below 0°C, the appliance can freeze.
To prevent the risk of freezing follow the instructions below:
Follow the supplier's instructions for the life cycle duration and possible disposal of the anti-
freeze liquid.
The excessive use of glycol could jeopardise the proper functioning of the appliance.
- 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 manufacturer guaranteed not to cause damage to the heat exchanger or other components of
the indoor unit. The antifreeze liquid must not be harmful to one's health. The instructions of the manufacturer of this liquid must be
strictly followed regarding the necessary percentage with respect to the minimum temperature at which the system must be kept.
- the materials used for the central heating circuit of Immergas indoor unit resist ethylene and propylene glycol based antifreeze liquids
(if the mixtures are prepared perfectly).
- An aqueous solution must be made with potential pollution class of water 2 (EN 1717:2002 or local standards in force).
Minimum temperature -15°C
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 wiring and a control thermostat (carefully read the installation instructions contained in the ac-
cessory kit pack).
The antifreeze systems described in this chapter are only to protect the indoor unit. The presence of these functions and devices
does not exclude the possibility of parts of the circuits outside the indoor unit from freezing.
If the indoor unit is installed in places where the temperature drops below 0°C, the domestic hot water connection pipes must be
insulated (if paired with storage tank unit).
The warranty does not cover damage due to interruption of the electrical power supply and failure to comply with that stated on the pre-
vious pages.
- indoor unit and outdoor unit are properly connected to each other and to the electrical power supply circuits;
- the units are continuously powered;
- the indoor unit is not in "off" mode;
- the units are not in anomaly (Parag. 2.5);
- the antifreeze unit and/or kit essential components are not faulty.
Indoor unit anti-freeze protection (both 0°C and -15°C) is only ensured if:
In the previously mentioned conditions and with the addition of the antifreeze kit, the indoor unit is protected against freezing
up to a temperature of -15°C.
