**SPECIAL INFORMATION

**

• The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.
• Fix the appliance in position as described in chapter “Installation / Preparations”.
• The appliance is pressurised. During the heat-up process, expansion water will drip from the safety valve.
• Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits. – Drain the appliance as described in chapter “Installation / Maintenance / Draining the appliance”
• Install a type-tested safety valve in the cold water supply line. Please note that, depending on the static pressure, you may also need a pressure reducing valve.
• Size the drain so that water can drain off unimpeded when the safety valve is fully opened. – Fit the discharge pipe of the safety valve with a constant downward slope and in a room free from the risk of frost.
• The safety valve discharge aperture must remain open to atmosphere.

Safety

2.1 Intended use
This pressure appliance is designed to heat DHW. Suitable dummy flanges, indirect coils, electric immersion heater and flanged immersion heaters can be fitted by contractors.
This appliance is intended for domestic use. It can be used safely  by untrained persons. The appliance can also be used in a non-do-mestic environment, e.g. in a small business, as long as it is used in the same way.
Any other use beyond that described shall be deemed inappropriate. Observation of these instructions and of instructions for any accessories used is also part of the correct use of this appliance.

2.2 General safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in excess of 43 °C.
WARNING Injury
The appliance may be used by children aged 8 and up and persons with reduced physical, sensory or mental capabilities or a lack of experience and know-how, provided that they are supervised or they have been instructed on how to use the appliance safely and have understood the resulting risks. Children must never play with the appliance. Children must never clean the appliance or perform user maintenance unless they are supervised.
Note
The appliance is pressurised.
During the heat-up process, expansion water will drip from the safety valve. If water continues to drip when heating is completed, please inform your qualified contractor.

Appliance description

You can use the appliance to supply one or several draw-off points.
The internal steel cylinder is coated in enamel and is equipped with an anode to protect the inside of the cylinder against corrosion. With all appliance versions, except SB 650/3 AC, the protective anode is equipped with a consumption indicator; a thermometer is also supplied.

Cleaning, care and maintenance

▶ Have the electrical safety of the fitted accessories and the function of the safety assembly regularly checked by a qualified contractor.
▶ Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning the appliance.

4.1 Protective anode
Appliance versions, except SB 650/3 AC: Signal anode with consumption indicator
Material losses
If the consumption indicator changes colour from white to red, have the signal anode checked by a heating contractor and if necessary replaced.

1. Signal anode with consumption indicator
2. white = anode OK
3. Red = ask your heating contractor to check

SB 650/3 AC
▶ Have the protective anode checked by a qualified contractor after the first two years of use. The qualified contractor will then determine the intervals at which it must be checked thereafter.
4.2 Scaling
Almost every type of water will deposit lime at high temperatures. This settles inside the appliance and affects both the performance and service life. The heating elements must therefore be descaled from time to time. A qualified contractor who knows the local water quality will tell you when the next service is due.
▶ Check the taps regularly. Limescale deposits at the spouts can be removed using commercially available descaling agents.
▶ Regularly activate the safety valve to prevent it from becoming blocked, e.g. by limescale deposits.

Troubleshooting

Telephone your qualified contractor. To facilitate and speed up your enquiry, please provide the serial number from the type plate (no. 000000-0000-000000):

8.2 Transport
SB S
Material losses
We recommend removing the cylinder casing for transportation to the installation location to prevent it from becoming dirty or damaged (see chapter “Installation / Preparing the DHW circulation line connection, if appli- cable”).

Installation

9.1 Preparing the DHW circulation line connection, if applicable
You can fit a DHW circulation line to the DHW circulation connection, or you can use the thermometer connection where appropriate (see chapter “Specification / Dimensions and connections”).
SB S
Note
Fit the cylinder casing with cover before making the water connection and, if necessary, the DHW circulation line or the flanged immersion heater.
The plinth trim should be fitted after the tightness check.
▶ If you install a DHW circulation line on the DHW circulation connection, cut an opening in the cylinder casing for the DHW circulation line near the connection (indentation in the foam).
▶ Remove the thermal insulation near the connection.
▶ Route the DHW circulation line through the opening in the cylinder casing and fit the DHW circulation line.
▶ Insulate the “DHW circulation” connection.
▶ Insert the adaptor supplied with flat gasket and an extension.
▶ Cover the hole in the cylinder casing with the adhesive rose supplied.

SB AC
Note
Extend the connection for the DHW circulation line before fitting the thermal insulation.
▶ Extend the DHW circulation connection to approx. 150 mm.
▶ Fit the thermal insulation. For this, observe chapter “Fitting the thermal insulation”.
▶ Fit the DHW circulation line.

9.2 Fitting the thermal insulation
The thermal insulation is available as accessory.
▶ Fit the thermal insulation according to the instructions supplied. For this, ensure that there is enough space for the installation task.
SB 602 AC | SB 1002 AC
▶ Insert the anode indicator extension through the hole in the cover plate.

9.3 Fitting the thermometer

▶ Insert the thermometer as far as it will go and align it.
9.4 Fitting the signal anode
SB S
Material losses
The appliance must not be operated without a consumption indicator or with a damaged one, otherwise water will leak out once the anode is depleted.

1. Transport protection
2. Signal anode with consumption indicator
   ▶ Remove the transport protection.
   ▶ Check the consumption indicator for transport damage.

SB 602 AC and SB 1002 AC
Material losses
When operating the cylinder without consumption indicator, leave the plug in the threaded hole.

▶ Pull the plug out whilst simultaneously pushing the pressure ring down.
▶ Push the open pipe end of the consumption indicator into the aperture of the anode.
▶ Affix the label “Signal anode information” in a clearly visible position on the thermal insulation.

9.5 Fitting accessories
Note
SB AC: The polystyrene cap in the lower flange aperture is also designed to position the thermal insulation correctly above the flange apertures. If you fit the special accessories into the lower flange aperture, then push the polystyrene cap into the upper flange aperture.
▶ Install the accessories in accordance with the operating and installation instructions supplied.
▶ Close the flange apertures with an indirect coil, flanged immersion heater or dummy flange. Maintain the DC separation towards the cylinder.

9.6 Water connection and safety assembly
9.6.1 Safety instructions
Note
Carry out all water connection and installation work in accordance with regulations.
