Hydraulic Connection - Immergas VICTRIX HYBRID Instructions And Recommendations

1.11 HYDRAULIC CONNECTION

In order not to void the primary heat exchanger warranty, before making the device connections, carefully clean the heating
system (pipes, radiators, etc.) with special pickling or descaling products to remove any deposits that could compromise cor-
rect device operation.
A treatment of the heating and water system water is required, in compliance with the technical standards in force, in order to protect the
system and the appliance from deposits (e.g. scale), slurry or other hazardous deposits.
In order not to void the heat exchanger warranty, you are required to comply with what has been prescribed in (Par. 1.30).
Indoor Unit hydraulic connection.
Hydraulic connections must be made in a rational way using the couplings on the appliance template.
The manufacturer declines all liability in the event of damage caused by the installation of an automatic filling system.
In order to meet the system requirements established by EN 1717 in terms of pollution of drinking water, we recommend installing the
IMMERGAS anti-backflow kit to be used upstream of the cold water inlet connection of the appliance. We also recommend using cate-
gory 2 heat transfer fluid (e.g.: water+ glycol) in the appliance's primary circuit (C.H. circuit), as defined in standard EN 1717.
To preserve the duration of appliance efficiency features, in the presence of water whose features can lead to the deposit of lime
scale, installation of the "polyphosphate dispenser" kit is recommended .
The dispenser cannot be installed inside the recessed frame.
3 bar safety valve
Discharge of the safety valve has been conveyed to the condensate drain trap outlet. Consequently, in the event of valve intervention, the
discharged liquid will end up in the sewer system through the drain pipe of the condensate drain trap.
In any case, the lower part of the appliance is fitted with a drain fitting (Ref. 3, Fig. 8) with the relative closure cap to check for the presence
of liquid in the discharge circuit and to check the intervention of the 3 bar safety valve.
Condensate drain
To drain the condensate produced by the appliance, it is necessary to connect to the drainage system by means of acid condensate resist-
ant pipes, with an internal Ø of at least 13 mm.
The system connecting the appliance to the drainage system must be carried out in such a way as to prevent occlusion and freezing of the
liquid contained in it.
Before appliance ignition, ensure that the condensate can be correctly removed. After first ignition, check that the drain trap is filled with
condensate (Parag. 1.32 Filling the condensate drain trap).
Also, comply with national and local regulations on discharging waste waters.
In the event condensate is not discharged into the wastewater drainage system, a condensate neutraliser must be installed to ensure com-
pliance with the parameters established by the legislation in force.
Outdoor unit hydraulic connection
For the hydraulic connection of the Audax.DK4 outdoor unit, refer to the related instructions booklet.
