3 bar safety valve
The drain of the safety valve must always be properly conveyed to a
draining funnel; consequently, in case of valve operation, the lea-
ked fluid will end up in the sewer system.
Condensate drain
To drain the condensate produced by the appliance, it is necessary
to connect to the drainage system by means of acid condensate re-
sistant 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 cor-
rectly removed. After first ignition, check that the drain trap is fil-
led with condensate.
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 compliance with the parameters established by the legisla-
tion in force.
A treatment of the heating and water system water is required, in
compliance with the technical standards in force, in order to pro-
tect 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 (Par. 1.28).

Water connections must be made in a rational way using the cou-
plings 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 category 2 heat transfer fluid (ex: water+glycol) in the boi-
ler'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 .
If you are using one or more booster pumps it is essential
to install a hydraulic separator (not supplied by Immer-
gas) downstream of the indoor unit.
1.8 CONNECTING THE CHILLER LINE
As far as connecting the cooling line is concerned, all the in-
structions contained in the outdoor unit instructions booklet
must be followed.
Make the connections directly on the indoor unit couplings, or
use the rear outlet kit (optional).
