HYDRAULIC CONNECTION.

In order not to void the heat primary exchanger
warranty, before making the boiler connections,
carefully clean the heating system (pipes, radiators,
etc.) with special pickling or de-scaling products to
remove any deposits that could compromise correct
boiler 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.
Hydraulic connections must be made in a rational way using the
couplings on the boiler template.
ATTENTION:
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 boiler. We also recommend using a
category 2 heat transfer fluid (ex: water + glycol) in the boiler's pri-
mary circuit (C.H. circuit), as defined in standard EN 1717.
To preserve the duration of appliance efficiency fea-
tures, in the presence of water whose features can
lead to the deposit of lime scale, installation of the
"polyphosphate dispenser" kit is recommended .
3 bar safety valve.
Safety valve discharge must always be conveyed through a draining
funnel. Otherwise, the manufacturer declines any responsibility
in case of flooding if the drain valve cuts in.

ELECTRICAL CONNECTION.

The appliance has an IPX5D protection degree; electrical safety of
the appliance is achieved only when it is connected properly to an
efficient earthing system, as specified by current safety standards.
ATTENTION:
the manufacturer declines any respon-
sibility for damage or physical injury
caused by failure to connect the boiler
to an efficient earth system or failure to
comply with the reference standards.
Open the control panel connections compartment (Fig. 5)
To carry out electrical connections, all you have to do is open the
connections compartment as follows.
Remove the casing:
1. Loosen the screw (a) at the bottom.
2. Place the control panel (b) horizontally;
3. Remove the screw (c) securing the control panel (b) cover (d);
4. Remove the cover (d) from the control panel (b);
At this point, it is possible to access the terminal board (e).
Also ensure that the electrical installation corresponds to maxi-
mum absorbed power specifications as shown on the boiler data
nameplate.
Boilers are supplied complete with an "X" type power cable without
plug.
