check the electrical continuity with the tank (in particular for anode
without grounding wire).
• 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 orifi ce,
unless otherwise specifi ed in the legislation in force in the country
of installation, must have a diameter in millimeters of not less than:
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 fl ange, easily accessible thanks to the
removable fl ange 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.
