2.2 General safety instructions
WARNING Burns
There is a risk of scalding at outlet temperatures in excess of 43 °C.
WARNING Injury
Where children or persons with limited physical, sensory or mental abilities are allowed to operate this appliance, ensure that this will only happen under supervision or after appropriate instruction by a person responsible for their safety.
Children should be supervised to ensure that they never play with the appliance!
Note
The appliance is under pressure. During the heat-up process, expansion water will drip from the safety valve. If water continues to drip when the heat-up process is completed, please inform your qualified contractor.
Appliance description
The thermal energy in the heating water from the heat pump or the solar collectors is transferred to the domestic hot water by two twin pipe indirect coils.
The internal steel cylinder is coated in special directly applied “anticor®” enamel and is equipped with a thermometer and a signal anode. The anode with consumption indicator protects the internal cylinder from corrosion.
Cleaning, care and maintenance
- Have a contractor regularly check the appliance, the safety assembly and all fitted accessories.
- Never use abrasive or corrosive cleaning agents. A damp cloth is sufficient for cleaning all plastic parts.
Signal anode 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.
Signal anode consumption indicator
- white = anode OK
- red = check by heating contractor required
Scaling
- Almost every type of water deposits limescale at high temperatures. This settles inside the appliance and affects both the performance and service life. The indirect coils and fitted accessories should therefore be descaled from time to time.
A heating contractor who knows the local water quality will tell you when the next service is due. - Check the taps/valves regularly. You can remove limescale deposits at the tap outlets using commercially available descaling agents.
Troubleshooting
Telephone your contractor.
To facilitate and speed up your enquiry, please provide the serial number from the type plate (000000-0000-000000):

Preparations
8.1 Installation site
- Always install the appliance in a room free from the risk of frost and near the draw-off point.
- Ensure the floor has sufficient load bearing capacity and evenness (see chapter “Specification / Data table”).
- Observe the room height and height when tilted (see chapter “Specification / Data table”).
Minimum clearances
- Maintain the minimum clearances.
8.2 Transport
For handling/lifting, use the lifting eyes provided, but never the “Optional DHW outlet” connection at the top of the appliance.
Installation
9.1 Fitting the thermal insulation, if appropriate.
- Position the appliance in its intended site.
- Fit the thermal insulation according to the instructions supplied. For this, ensure that there is enough space for the installation task. You can then link the appliance into the heating and DHW system.
9.2 Fitting the signal anode
Material losses
When operating the cylinder without consumption indicator, leave the plug in the fitting.
- Pull the plug out by simultaneously pushing the pressure ring down.
- Push the open pipe end of the consumption indicator into the aperture for the anode.
9.3 Fitting the thermometer and temperature sensor
- Insert the thermometer as far as it will go and align it.
- Insert the temperature sensor as far as it will go into the sensor well for the HP return sensor. Apply heat conducting paste.
9.4 Where appropriate, fit the flanged or threaded immersion heater.
- Remove the dummy flanges and plugs in order to mount the flanged or threaded immersion heater. Maintain the DC separation towards the cylinder.
9.5 Heating or solar installation
- Prior to connecting the heating water lines or the solar thermal system, flush the indirect coils with water.
- You may connect both indirect coils to the “heat pump return” and “solar flow” (see chapter “Specification / Dimensions and connections”). To make the connection, use the indirect coil connection piece which is available as an accessory.
- Connect the hydraulic connections with flat gaskets.
- Fit the sensors for the control units used according to the relevant installation instructions (for sensor well, see chapter “Specification / Dimensions and connections”).
- Route the connecting lead to the solar or heating circuit control unit.
9.5.1 Water quality, solar circuit
A glycol/water mixture of up to 60 % is permitted for the indirect coil in the solar circuit if only dezincification-resistant metals, glycol-resistant gaskets and diaphragm expansion vessels suitable for glycol are used throughout the installation.
9.5.2 Oxygen diffusion
Material losses
Avoid open heating systems and plastic pipes in underfloor heating systems which are permeable to oxygen.
In underfloor heating systems with plastic pipes that are permeable to oxygen and in open vented heating systems, oxygen diffusion may lead to corrosion on the steel components of the heating system (e.g. on the indirect coil of the DHW cylinder, on buffer cylinders, steel heating elements or steel pipes).
Material losses
The products of corrosion (e.g. rusty sludge) can settle in the heating system components and can result in a lower output or fault shutdowns due to reduced cross-sections.
Material losses
Avoid open vented solar thermal systems and plastic pipes which are permeable to oxygen.
With plastic pipes that are permeable to oxygen, oxygen diffusion may lead to corrosion on the steel components of the solar thermal system (e.g. on the indirect coil of the DHW cylinder).
