Immergas MAGIS PRO 12 V2 Instructions And Recommendations page 10

They must be attached to a heating system suitable for their capacity and voltage.
"Anti-Legionella" heat treatment of the Immergas storage tank (only if paired with a storage tank unit and function enabled
when the system is provided with temperature control).
The storage tank unit must also be installed in an environment in which the temperature cannot fall below 0°C.
Anti-Legionella can only be activated if the optional DHW electrical resistance is installed;
The anti-Legionella function is programmed directly on the control panel.
During this phase, the temperature of the water inside the tank exceeds 60°C with the subsequent risk of burns.
Keep this domestic hot water treatment under control (and inform the users) to prevent unforeseeable damage to people, animals, things.
If required install a thermostatic valve on the domestic hot water outlet to prevent scalding.
The appliance is built to also operate in cooling mode.
If cold water production, during summer, could interfere and damage the central heating only
systems, necessary precautions must be taken to prevent that an unintentional production of
cold water enters the heating only system.
The minimum water content required within the system is 50 litres; otherwise, it will be neces-
sary to install an inertial storage tank (optional).
For proper system operation, make sure that the minimum flow rate in operating conditions
never drops below 750 l/h.
When the circulation within each room central heating loop is controlled by remotely operated valves, it is important to guar-
antee the minimum water content (50 litres), even if all the valves are closed.
When the circulation within each or certain room central heating loops is controlled by remotely operated valves, it is impor-
tant to guarantee the minimum flow rate, even if all the valves are closed. It is necessary to have a loop that is always open on the
system (by-pass or non-intercepted zone), to allow some functions such as, for example, the antifreeze function.
Failure to comply with the above implies personal responsibility and invalidates the warranty.
