3. INSTALLATION
Installation of the product and auxiliary equipment in relation to the heating system must comply with all current Standards and Regulations
and to those envisioned by the law.
Installation relating to the connections of the system, commissioning and the check of the correct functioning must be carried out in
compliance with the regulations in force by authorised professional personnel with the requisites required by the law, being national,
regional, provincial or town council present in the country within which the appliance is installed, besides these present instructions.
Installation must be carried out by authorised personnel who must provide the buyer with a system declaration of conformity certificate and
will assume full responsibility for final installation and as a consequence the correct functioning of the installed product.
All operations must be performed with mains power disconnected.
WARNING : installation, connections and testing must be performed by qualified personnel acting in compliance with the standards in
force and as described in the heating appliance instruction booklet Correct operation of the appliance is only guaranteed for pumps and
valves approved by La Nordica. La Nordica is not liable for any improper use of the appliance.
NB. All piping must be insulated in accordance with applicable standards (in Italy law 10/91).
IMPORTANT: temperature safety sensors must be in place on the machine or at a distance no greater than 30 cm from the flow connection
of the thermo-product. Whenever the thermo products lack a device, those missing can be installed on the thermo product flow pipe,
within a distance no greater than 1m from the thermo product.
NOTE: the standard UNIVERSAL module is equipped with a 3-bar SRV valve and a 95°C TRV with double thermal safety to be installed in
the hydraulic system in compliance with all current Standards and Regulations and pursuant to the Law.
Before installation, accurately wash the pipes of the system in order to remove any residuals that could compromise the correct functioning
of the appliance.
IMPORTANT:
a) In case of water leaking, close the water supply and promptly warn the after sales technical service;
b) The system working pressure must periodically be checked.
c) If not using the boiler for a long period of time, it is recommended that the after sales technical service is contacted to carry out at
least the following operations:
•
close the water taps of both the thermal system and the domestic hot water system;
•
empty the thermal system and the domestic hot water system if there is risk of freezing.
4. WATER CONNECTION
IMPORTANT: after having transported / handled the All Inclusive Module, check tightness of all the compression nuts on the copper pipes.
Take special care when connecting the Module to the plumbing system to avoid bending the copper pipes in the KIT. To counter the
tightening force exerted on the plumbing system connection pipe, use a wrench or other tool on the terminal in the KIT being connected.
WARNING: after having connected the Module to the plumbing system, check tightness of all the compression nuts on the copper pipes.
The two All Inclusive Modules are already equipped with a VSP valve (Thermal Relief Valve) and a SRV valve (Safety Relief Valves), as
well as being pre-arranged to be installed in open vessel system.
The VST valve (Thermal Relief Valve) is supplied disassembled with the UNIVERSAL Module, while it is already installed in the All Inclusive
Module for ITALYTERMO DSA.
IMPORTANT: for open vessel or closed vessel installation refer to the instructions manual of the thermoproduct combined with the All
Inclusive Module.
