Installation
Installation must be carried out in accordance with the
prevailing regulations, the codes of practice and the
recommendations in these instructions.
SR 130 calorifiers are designed to be placed under the wall-hung
boiler.
1 Connecting the DHW tank to the boiler (primary circuit)
Prior connecting the heating circuit hydraulic connections,
it is vital that the heating circuits are rinsed to prevent
articles that may damage certain parts from being
introduced (safety valves, pumps, non return valve...).
When making the connections, it is imperative that the
standards and corresponding local directives are
respected.
Thesedomestichotwatertankscanoperateatamaximumoperating
pressure of 10 bars. As a general rule, the tanks operate at 7 bars.

2 Connecting the tank to the domestic water circuit (secondary circuit)
2.1 Specific precautions
Before making the connection, rinse the domestic water inlet
pipes to prevent the introduction of metal or other particles into the
DHW tank.
2.2 Provision 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.
2.3 Isolation valves
Hydraulically isolate the primary and secondary circuits using stop
valves to facilitate maintenance operations on the calorifier. The
valves make it possible to carry out maintenance on the tank and its
components without draining the entire installation.
These valves are also used to isolate the calorifier when conducting
apressurisedcheckon the leak tightnessoftheinstallationifthetest
pressure for the calorifier is greater than the admissible operating
pressure.
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
2.4 Connecting the domestic cold water
To carry out connection with cold water (See next page). 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 non-return valve to the domestic cold water
circuit.
2.5 Safety valve
In compliance with the safety rules, fit a sealed safety valve
to the tank's domestic cold water inlet.
Calibration of the safety valve : output 10 bar.
For France, we recommend hydraulic safety units fitted with a
membrane with the NF marking.
- Integrate the safety valve in the cold water circuit.
- Install the safety valve close to the calorifier in a place which is
easy to access.
Dimensions
ThesafetyunitanditsconnectiontotheDHWtankmustbeofatleast
the same diameter as the cold water supply pipe in the tank's
domestic circuit.
No isolating devices should be located between the safety valve or
unit and the tank.
Thesafetyunitoutletpipemusthaveauniformandsufficientgradient
and its diameter must be at least equal to that of the outlet opening
in the safety unit (to prevent the flow of water being hindered if the
pressure is too high).
The outlet pipe in the valve or safety unit must not be blocked.
France
The level of the safety unit must be lower than that of the cold water
inlet to enable draining. Otherwise, fit a drainage pipe to the lowest
point of the tank.
Germany
Definethedimensionsofthesafety valve in accordance with the DIN
1988 standard :

Commissionning
1. Fill the calorifier via the cold water input pipe.
2. Carefully degas the DHW tank and the distribution network in
order to eliminate noises and hammering caused by trapped air
moving in the pipes during draw-off.
To do so:
- Fill it completely with water, leaving a hot water tap open.
- Only reclose this valve when the flow is regular and there are no
noises or hammering in the pipes.
- Then successively degas all the hot water pipes by opening the
corresponding valves.
3. Check the safety devices (particularly the valve or safety unit),
referring to the instructions provided with these components.
During the heating process, a certain amount of water may
flow through the valve or safety unit; this is caused by
water expansion. This phenomenon is completely normal
and must in no event be hindered.

Maintenance and periodic checks
Magnesium anode
The magnesium anodes must be checked at least every 2, years.
After the first check, determinethe frequency of future checks onthe
basis of anode wear.
The anodes can be checked by two methods:
Inspection:
- the anode must be replaced if its diameter is less than 15 mm
(original diameter = 33 mm).
Function test:
- disconnect the earth wire from the anode.
- measure the strength of the current between the tank and the
anode ; if the current measured is less than 0.1 mA, the anode
should be replaced.
If the anodes must be replaced, proceed as described below.
Valve or safety unit
The valve or safety unit must be operated at least once a month in
order to ensure that it is operating correctly and to be forewarned of
any overpressure which would damage the DHW tank.
Exchanger
In hard water regions, it is advisable to ask the fitter to descale the
DHW tank exchanger once a year in order to maintain its level of
performance.
Cladding
The cladding of the DHW tank can be cleaned with soapy water.
Procedures to follow for descaling, or checking or replacing the magnesium anodes
Use a new leak tight seal on the inspection trap.
1. Turn off the domestic cold water inlet.
2. Open a hot water tap.
3. Open the valve on the safety unit.
4. Remove the hood Ausing a broad-bladed screwdriver (see
detail) and then remove the insulation.
5. RemovethesensorBfromthethimbletubeintheinspectiontrap

6. Remove the cover (13 mm spanner).
7. Drain the calorifier.
8. Check and remplace the anode Dif necessary (13 spanner).
9. Check the exchanger:
Descale the exchanger in order to maintain its performance
levels.
- Remove limescale deposits in the form of sludge or strips in the
bottom of the tank.
- Onthe other hand,donottouchlimescaleadhering to thewallsof
the tank as it provides effective protection against corrosion and
improves the insulation of the DHW tank.
10. Reassemble the parts. Replace the leakproof seal E on the
hatch. Put it in place with the retainer ring Ftaking care to place
the positioning lug on the gasket pointing to the outside of the
calorifier.
11. Make sure the temperature sensor is pushed all the wayinto the
sensor socket.
12. Check for leak tightness after assembly.
The screws retaining the visit trap must be tightened to
6 Nm +1/-0. Use a dynamometric spanner. Approximately
6 Nm is obtained by holding the box spanner by the small
lever.
13. Switch on.
14. Re-assemble the cover A.
