HYDRAULIC CONNECTION

In order not to void the warranty, before making indoor unit connections, carefully clean the heating system (pipes, radiators,
etc.) with special pickling or de-scaling products to remove any deposits that could jeopardise proper hydronic module opera-
tion.
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.
Water connections must be made in a rational way using the couplings on the indoor unit 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 indoor unit. We also recommend using cat-
egory 2 heat transfer fluid (ex: water + glycol) in the internal unit primary circuit (heating and/or cooling 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 .
