Antifreeze Protection - Immergas VICTRIX OMNIA Manual

ANTIFREEZE PROTECTION

Minimum temperature -5°C
The appliance comes standard with an antifreeze function that activates the pump and burner when the system water temperature in the
appliance falls below 4°C.
In these conditions, previously listed, the appliance is protected against freezing up to an ambient temperature of -5°C.
If the appliance is installed in a place where the temperature drops below -5°C, the appliance may freeze.
To prevent the risk of freezing follow the instructions below:
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 appliance. 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 appliances resist ethylene and propylene glycol based antifreeze liquids
(if the mixtures are prepared perfectly).
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).
In the previously listed conditions ad with the addition of the antifreeze kit, the appliance is protected against freezing up to a
temperature of -15°C.
Appliance antifreeze protection is thus only ensured if:
- the appliance is correctly connected to gas and electricity power supply circuits;
- the appliance is powered constantly;
- the appliance is not in "off" mode.
- the appliance is not in anomaly conditions (Par. 2.5);
- the appliance essential components are not faulty.
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 page.
If the appliance is installed in places where the temperature falls below -5°C the domestic hot water and central heating attach-
ment pipes and the condensate drain pipe must be insulated.
The antifreeze systems described in this chapter are only to protect the appliance; the presence of these functions and devices
does not exclude the possibility of parts of the system or domestic hot water circuit outside the appliance from freezing.
