3 Technical description
3.1 General description
The SR130 domestic hot water tank can be connected to traditional
wall-hung boilers. The appliance is delivered with an NTC sensor with
connector and a mounting rail.
Main parts:
4The tanks are made of high quality steel lined with food quality
standard enamel vitrified at 850°C, which protects the tank from
corrosion.
4The heat exchanger welded into the tank is made of smooth
tubing, the external surface of which, which is in contact with
domestic water, is enamelled.
4The appliance is highly insulated with CFC-free polyurethane
foam, which reduces thermal losses to a minimum. The insulating
material can be easily detached from the tank. This measure
facilitates the recycling of materials.
4The outside casing is made of painted steel sheeting.

4.5.2. Connecting the calorifer to the domestic
water circuit (secondary circuit)
When making the connections, it is imperative that the standards and
corresponding local directives are respected.
nSpecific precautions
Before making the connection, rinse the drinking water inlet
pipes in order not to introduce metal or other particles into the
appliance’s tank.
nProvision for Switzerland
Make the connections according to the instructions of the Société
Suisse de l’Industrie du Gaz et des Eaux. Comply with local
instructions from water distribution plants.
nSafety valve
CAUTION
In accordance with safety rules, a safety valve calibrated
to 7 bar is mounted on the tank’s domestic cold water inlet.
France: We recommend NF-marked hydraulic membrance safety
control units.
All countries except Germany: 7 bar safety valve (0.7 MPa)
Germany: 10 bar safety valve (1.0 MPa) maximum.
4Integrate the safety valve in the cold water circuit.
4Install the safety valve close to the calorifer in a place which is
easy to access.
nSize
4The diameter of the safety unit and its connection to the calorifer
must be at least equal to the diameter of the domestic cold water
inlet on the calorifer.
4There must be no cut-off element between the valve or the safety
unit and the domestic hot water calorifer.
4The outlet pipe in the valve or safety assembly must not be
blocked.
To avoid restricting the flow of water in the event of overpressure:
4The safety device drain pipe must have a uniform and sufficient
gradient and its diameter must be at least equal to that of the outlet
opening of the safety device (to prevent the flow of water being
hindered if the pressure is too high).
4. Installation SR130
15 26/03/2014 - 300009755-001-03

4The cross section of the discharge pipe from the safety unit must
be at least equal to the cross section of the opening of the safety
unit outlet.
Germany: Define the dimensions of the safety valve in accordance
with the DIN 1988 standard.
Capacity (litres)
Dimension of the valve
Min. dimension of the inlet
connection
Heating output
(kW) (max)
< 200 R or Rp 1/2 75
200 to 1000 R or Rp 3/4 150
4Fit the safety valve above the calorifer to avoid draining the tank
during servicing.
4Install a drainage valve at the lowest point on the calorifer.
nIsolating valves
Hydraulically isolate the primary and secondary circuits using stop
valves to facilitate maintenance operations on the unit. The valves
make it possible to carry out maintenance on the calorifer and its
components without draining the entire installation.
These valves are also used to isolate the calorifer unit when
conducting a pressurised check on the leak tightness of the
installation if the test pressure is greater than the admissible operating
pressure.
CAUTION
If the mains pipes are made of copper, fit a sleeve made
of steel, cast iron or any other insulating material between
the tank’s hot water outlet and the pipes to prevent
corrosion to the connection.
nConnecting the domestic cold water
Make the connection to the cold water supply according to the
hydraulic installation diagram.
¼Refer to the installation and maintenance instructions of the
boiler
Install a water drain in the boiler room and a funnel-siphon for the
safety unit.
The components used for the connection to the cold water supply
must comply with the prevailing standards and regulations in the
country concerned. Fit a one-way valve to the domestic cold water
circuit.
4In regions where the water is very hard (Th > 20°F), we
recommend fitting a softener. Water hardness must always be
between 12°F and 20°F to be capable of providing effective
protection against corrosion. The softener does not bring about a
derogation from our warranty provided that it is approved and set
pursuant to the codes of practice and is regularly inspected and
maintained.
SR130 4. Installation
26/03/2014 - 300009755-001-03 16

nPressure reducer
If the mains pressure exceeds 80% of the calibration of the valve or
safety unit (e.g. 5,5 bar (0,55 MPa) for a safety unit calibrated to 7 bar
(0,7 MPa)), a pressure reducer must be installed upstream of the
appliance. Install the pressure reducer downstream the water meter
in such a way as to ensure the same pressure in all of the installation
pipes.
nDomestic hot water circulation loop
To guarantee the availability of hot water as soon as the taps are
turned on, a circulation loop between the draw-off points and the
recirculation pipes in the DHW calorifer can be installed. A non-return
valve must be included in this loop.
Run the domestic hot water circulation loop via the boiler
control system or an additional timer program to optimse
energy consumption.
nMeasures to take to prevent hot water flow return
Fit a one-way valve to the domestic cold water circuit.
