2 Installation
2.1 Receipt of the product
10x
– Seal + gasket kit + coloured indicator
– Fittings kit (optional)
lWARNING!
The instruction manual is an inte-
gral part of the device and should
therefore be read and stored
carefully.
dPROHIBITED
Packaging material must be prop-
erly disposed of and kept out of
children’s reach as it may repre-
sent a hazard. Disposal must be
performed in line with applicable
laws.
2.2 Assembly
Authorised personnel: specialised installer
or plumber, assigned by the metering oper-
ator.
lWARNING!
Only authorised and suitably
trained personnel with sucient
technical experience may install
and operate the device.
Before installing the device, make sure that
the two sections of tube are even to prevent
mechanical stress, clean them with care (es-
pecially in the case of empty tubes) and let
water run for a while, using a stub pipe on
the tube instead of the meter.
If there is no water in the pipeline, open the
valve upstream of the device before install-
ing it. This is necessary because opening
the valve after installation is complete may
cause air suction that could damage the de-
vice.
Before using the meter, rst fully remove air
from the pipe and the device itself. The in-
terception/adjustment valves must be fully
open when doing this. Open the valve at the
start rst and then the valve at the end.
When replacing the meter, it is recommend-
ed to replace the gasket on the tting. Rec-
ommended gasket hardness: minimum 80
Shore A.
Tighten the nut with a torque wrench and
use a counter wrench to hold the meter in
position. Maximum tightening torque: 40
Nm.

12
Install the meter:
– protected from frost (insulate it if necessary with insulation material) and in the lower
part of the system to prevent air accumulation;
– protected from blows and tampering, where readings are easy to make;
– so that the direction of the arrow on the device coincides with the ow direction.
Install proper interception valves upstream and downstream of the meter to permit main-
tenance operations and inspections on the device, as well as to check the system.
The installation of a non-return valve inside or outside the meter is also recommended (see
dedicated data sheet).
lWARNING!
Before positioning the seal, make sure that it is not damaged.
Make sure that the seal is not damaged during installation.
Make sure that the level of the seal matches that of the tubing.
Check that the seal does not protrude from the tube.
Make sure that the surfaces of the ange are clean and undamaged.
lWARNING!
Check the seal hold to prevent leakage.

13
Installation position
Observe the indications on the dial (letters
H and V):
– H: the meter must be installed with the
dial in a horizontal position;
– V: the meter must be installed with the
dial in a vertical position;
– H and V: the meter may be installed with
the dial in either a horizontal or vertical
position;
– If not shown, avoid vertical installations
with downward ow, or with the dial fac-
ing downwards.
Straight sections and ow straighteners
When using straight sections upstream and/
or downstream of the meter, refer to letters
U and D on the dial. If the letters U and/or
D are followed by the letter S, install a ow
straightener.
Allowable water pressure (ISO 4064-1)
The maximum allowable pressure (MAP) is
16 bar, and is displayed on the meter dial. If
not indicated on the dial, it must be 10 bar.
These values must never be exceeded.
The maximum allowable pressure (MAP)
downstream of the meter must be greater
than or equal to 0.03 Mpa (0,3 bar).
Commissioning
Before putting the meter into operation,
completely vent the air from both the pipe
and the meter itself (rotate it if necessary).
The interception/adjustment valves must be
fully open when doing this. Open the valve
at the start rst and then the valve at the
end.

14
3 Seals
A seal is applied to the meter: it cannot be
opened without breaking it. Any interven-
tion must therefore be carried out by a cen-
tre authorised by the manufacturer.
4 Use
ElecTo SJ is ideal for both cold and hot wa-
ter residential use where compactness, ex-
ibility and the availability of an integrated
radio reading make the dierence.
5 Programming the radio
ElecTo SJ is supplied with factory-set setup
data.
The radio is activated after the passage of
10 litres of water.
Programming mode is activated by tapping
the magnetic key symbol with the magnetic
key.
The cumulative time for this mode is 120
minutes.
The radio settings, such as the type of ra-
dio frame and data transmission frequency,
have a default factory setting. However, if
necessary, they can be changed using the
specic programming kit after enabling pro-
gramming mode.
For further information, contact the manu-
facturer.
The app allows the following parameters to
be read and programmed:
– Radio settings
– Radio AES key
– Periodic reading
– Alarms setting
– Alarms reset
– Date/time synchronization
– Delivery point

8 Maintenance
8.1 Battery (default)
The meter is tted with a 3.6V manganese
lithium battery that cannot be recharged or
replaced.
The estimated lifespan of the battery is 13
years, calculated using factory set-up and
with the following operating conditions:
– from -10°C to +0°C for 10% of the lifespan
– from 0°C to +30°C for 80% of the lifespan
– from +31°C to +55°C for 10% of the
lifespan
lWARNING!
Humidity and intense heat may
damage the battery and reduce
its lifespan.
The device calculates the useful remaining
life of the battery based on memorized pa-
rameters, for example, estimated consump-
tion of the electronic board in standby, con-
sumption in transmission and the number
of transmissions made.
Battery life depends on the data transmis-
sion frequency you choose to set.
8.2 Cleaning
No particular cleaning procedures are re-
quired. However, the installation area
should be kept clean and periodic checks
should be performed to ensure the required
environmental conditions are met.

trile, cosmetic solvents, sodium
hydrate (10%), ammonium hy-
drate (10%), nitric acid (40%), po-
tassium dichromate, acetone,
diesel naphtha, petrol.
8.3 Disposal
The device is made from various materials
such as: metal and plastic materials, electri-
cal and electronic components. It must be
