calcareous drops into the plate heat exchanger. It is
mandatory to avoid to run dry the circulation group.
The primary circuit must be connected to a boiler
temperature
check
(thermostat).
All
electricity
connections have to be executed by qualified
personnel only.
•
Verify that the position where Boilers are to open are
large enough to allow for free passage toward the outside
without any need for demolition. The guarantee does not
cover any costs derived from a failure to observe this
point.
•
Handling phases require movement of equipment with
weight exceeding 30 kg and require the use of proper
hoisting and transport means. For this purpose,
receptacles are to be moved only when empty by means
of special platforms or hoisting eyebolts.
•
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 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 safety valve, a hydraulic load shut-off device, all
accessories necessary for working in safety with boilers.
•
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 boiler.
•
If the sanitary water system exceeds admissible boiler
pressure levels, install a pressure regulator at an adequate
distance from the boiler to prevent overheating of the
pressure regulator itself.
•
The Anoden Tester device allows a periodic control of the
efficiency of the magnesium-anode and cathode protection
and in case replace the magnesium-anode at a later stage.
After a first replacement, it is recommended to arrange
periodical maintenance and replacement of the anodes
without waiting for their complete degradation. This is due
to the fact that only an updated and efficient protection
system will ensure a long duration of the equipment. In the
case in which the operating conditions (temperature and
water features) lead to a high deterioration of the
magnesium anodes, it is possible to install anodes with
impressed electricity that are available on request.
•
It is reminded that all the electronically equipment are to
be always connected to the ground. Upon start-up and
after some days of operation, check bolt tightening on the
flange, easily accessible thanks to the removable flange
covering.
6. Connections
6.1 Hydraulic 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 boiler 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.
•
DO NOT START THE CIRCULATION GROUP
BEFORE THE BOILER IS FILLED UP WITH
WATER
6.2 Electric connections
At installation of the Piastraterm boiler, connect the
electricity supply of the sanitary circulation
group provided with the product. Usually, it is
recommended to connect the circulation group
to the electricity supply network through an independent
switch and keep such circulation group always in use
(without the use of any thermostat) in order to avoid
calcareous deposit phenomenon into the plate to plate
heat exchanger.
Do not start the circulation group
before the boiler is filled up with water
.
Boiler Piastraterm can be supplied with the electronic
display for calorifiers Easy Conctrol mounted on the tank
and not wired
(only for models that are compatible for
it).
In this case connections related to the electricity supply
box have to be executed.
ATTENTION!! Carefully read the usage instructions of
the electronic supply box Easy Control for all
information related to connections, use, programming,
functionality
features,
safety
and
product
recommendations!
7. 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
