.• Equipment installation and operation in respect of these
instructions must always respect norms of national and local laws
in the place of installation. In particular, the inlet connection for
cold sanitary water supply to the water system must take place by
means of a hydraulic safety group in accordance with norm EN
1487:2002, including at least one shut-off valve, a relief valve, a
relief valve control device, a hydraulic load shut-off device, a
safety valve whose orifice, unless otherwise specified in the
legislation in force in the country of installation, must have a
diameter in millimeters of not less than:
5
V
V being the volume in litres of the Water heater, with a minimum of
15 mm. The valve must be calibrated to a pressure of no higher
than the maximum operating pressure of the Water heater and
connected without any cut-off units.
This plant shall also have an adequate expansion system both on
the heating side and on the sanitary side.
Even when laws permit that said expansion system can be made
up only of one properly sized safety valve, it is best to install a
membrane closed non-toxic expansion tank also to prevent
continuous opening of the safety valve and to prevent needlessly
overloading the water heater.
• If the sanitary water system exceeds admissible water heater
pressure levels, install a pressure regulator at an adequate
distance from the water heater to prevent overheating of the
pressure regulator itself.
• In general with sanitary hot water production plants, follow norms
and local regulations regarding water treatment in accordance with
characteristics. The guarantee does not cover any damages
derived from failure to comply with the aforementioned
prescriptions.
• Equipment electrical connections must always be earthed.
• The progressive consumption of magnesium anode can vary
based on operating conditions and on the nature of the water.
At the beginning of use, plan frequent magnesium anode checks
to verify consumption and to organise for periodic replacements at
least once per year.
• Upon start-up and after some days of operation, check bolt
tightening on the exchanger flange, easily accessible thanks to the
removable flange covering.
3. Connections
The plant connection diagram shown here within is intended solely
as a guideline and is not binding in as much as it is the job of the
designer of the plant onto which the water heater will be installed
to evaluate, in accordance with current installation norms, the best
plant diagram for use in compliance with limits set by data stated
by the manufacturer.
4. Operation
The maximum operating temperatures reported in this document
and on the equipment data plate are to be understood as
maximum resistance temperatures in the internal covering of the
water heaters. The maximum temperature of use must respect
national norms regarding energy consumption.
5. Disposal
At the end of the working life cycle of this product,
its metal components must be given to operators
authorised in the collection of metal materials for
recycling, while all non metal components must be
given to operators authorised for their separate
disposal.
Products must be managed, if disposed of by the final client, as
similar urban waste and therefore respecting town laws in the town
where they are located. They must never however be managed as
household waste.

6.2 Installation
Electric heater installation must be performed in accordance
with instructions by a professional with the necessary
qualifications in compliance with current specifications in
order to eliminate any risks.
Remember to disconnect electrical power before installation.
Check device conditions in all its parts and correspondence
with standard accessories (gasket and power cable). Do not
in any way tamper with or modify parts of the resistance and
avoid placing any weight on it even when packaged.
Check that the supply voltage to which the heater will be
connected is in compliance with information printed on the
resistance itself (
±
10%) and that the power supply circuit
responds to local regulations.
Verify that line cables are sized according to power.
Make sure that the system is provided with ground
connection.
