| 2. MOUNTING INSTRUCTIONS | |
| Environment This device is delivered in sturdy packaging in order to avoid damage during transport. This packaging consists mainly of recyclable materials. We request that you dispose of the packaging accordingly for recycling purposes. | |
| Installation The device should be installed in accordance with the drawing on the first page of the user manual. Any other installation position may result in serious damage to the device. Installation should take place as close as possible to a cold water connection. The product should be protected from the effects of frost (for example in caravans, summer houses, etc.). | |
| When mounting swivels and squeezed joints, always use 2 open-end spanners in order to prevent bending and twisting pipes and accessories. |

Frost
If there is the risk of frost in a room, the device should not be installed in this room. If, despite this advice, the device is installed in a room where there is a risk of frost, the device should be emptied before the risk arises.

Placement on the wall
Figure B
- The appliance must be fitted on a stable and solid wall. The wall must be able to at least bear the total weight of a full wall boiler.
- Determine a suitable place for the wall boiler. Insert the cotter bolts in the wall using a suitable tool. Make sure that the cotter bolt hooks are facing upwards.

IMPORTANT: In the unlikely event that the device is connected to the mains power supply without being filled with water, or if for some reason the device switches off after a short while, please disconnect the plug from the wall socket to allow the device to cool down.
Connection to the water supply
Figure A
- The water connections are 1 / 2^n .
- Connect the cold water supply to (11). Fit an inlet combination in between.
- Always use the rubber rings with filter supplied to prevent leaks.
- Connect (6) the piping for the hot water.
| ! | Connection to the electricity supply The device must be filled with water. Only then may the device be connected to the electricity supply (insert the plug in the wall socket). Connection of the device to the power supply network must take place in accordance with electric installation standards and as specified by local laws and regulations. The device must be directly connected to the power supply network (230V) via an electrical cable and plug. |
| Avoid danger from damaged power supply cables. In the event of damage, the device must be replaced by the manufacturer or its customer service department, or by an equivalently-qualified person. | |
| ! | Ensure that the addition of this device will not overload the fuse protection in your mains. Internal modifications to the product may cause problems if this work is not carried out by authorized and qualified technical staff. The warranty only applies if the product has not been modified in any way, i.e. subject to it being in un-changed condition. |
| ! | In order to avoid creating an unsafe situation by inappropriate resetting of the maximum temperature safety device, this unit may not be powered via an external switching device (a time switch for example) or connected to a circuit, which is regularly switched on and off by the power supply company. |
| ! | Important: Never connect the plug to the wall socket if the device is not yet filled with water! |

3. USER INSTRUCTIONS

The device must be filled with water before connection to the electrical supply!

The device should always be connected to a safety unit!

To fill the appliance: Open one of the hot water draw-off points connected to the wall boiler. Then open the tap in the inlet combination. When the water starts to flow out of the draw-off point the wall boiler has been filled. The device only switches on again if the temperature falls below this setting. (See troubleshooting)
When filling for the first time, the hot water valve in the low-pressure tap fitting must be open so that water can flow into the device. If the device is not filled with water beforehand during installation, the automatic safety device will activate and switch off the device. (See troubleshooting instructions on how to act in the event of a fault.)

Temperature setting
Turn the on/off button to switch the wall boiler on. The 'ON' light comes on.
Turn the button on the right to set the required temperature. The 'HEATING' light will come on until the water has been heated.
Stand Description
| Water is not heated |
| LOW Water is moderately heated |
| E Energy-saving position |
| HIGH Water is heated to maximum temperature |
Usage and maintenance
Please refer to the previous section for details of the thermostat settings. We recommend you use position E^ as this guarantees maximum energy efficiency and the lowest lime scale building. By maintaining the water temperature at approximately 55^ ; furthermore lime scale build-up and heat loss are much lower than at higher temperatures.
As the water that is used for washing the dishes has a temperature of approximately 45 to 50^ , cold water has to be mixed in to reach this temperature. At a water temperature of 60^ , you will be able to draw off about 14 litres of 45^ .
Operation of the device is indicated by the indicator light, which lights up when the device is on and extinguishes when the set temperature is reached or the device is turned off.
DEGBNLFR
| During heating, the volume of the water in the device expands, causing a flow of water ("expansion water") from the safety unit. This is perfectly normal and no preventive action needs to be taken. | |
| Frost When the device has not been used for an extended period, it must be protected against the effects of frost. Leave the power supply on and set the thermostat knob to „LOW“. When set to this position, the device maintains the water temperature at approximately 7°C. If the device is to be disconnected from the power supply, it must be emptied completely in order to avoid the risk of damage caused by freezing. | |
| 4. MAINTENANCE | |
| This device does not require any maintenance by the user. Professional maintenance should always be carried out by an expert. | |
| As water expands when heated, the pressure will increase in the device vessel with the connected hot water pipe(s). In order to limit this increase in pressure, a safety unit is required. This is a combination of a check valve, which prevents hot boiler water from flowing into the cold supply pipe, with a relief valve that limits the pressure in the device to a maximum of 8 bar, and a Stop valve in front of the check valve in order to be able to disconnect the device from the water mains. | |
| The relief valve is provided with a discharge hose for discharging expansion water from the device to the sewer. | |
| The steel storage vessel is provided with an enamelled layer that prevents the formation of corrosion. In case of damage to the enamelled layer, a magnesium anode mounted in the storage vessel will make sure that the underlying steel is protected. | |
| The magnesium anode protects the tank against corrosion. This is a cathodic process, during which the anode slowly dissolves. The anode should therefore be inspected, and replaced if necessary, by a recognized fitter every 2 years. | |
| Check the functioning of the inlet combination by turning the large knob on the inlet combination once a year, allowing water to flow out, and closing it immediately. This will prevent the valve of the inlet combination from getting stuck. Also check the drain for blockages. If it is blocked, unblock the drain or instruct a third party to do this. | |
| If faulty, never try to repair the device yourself. Please contact the nearest service specialist or the party that supplied the device originally. | |
| De-scaling A service inspection should be performed by authorized and qualified technical staff every year. De-scaling of the device during this inspection is highly recommended, especially when you live in an area with hard water exceeding 12°dH (German standard of hardness). Higher water temperature will intensify calcification. It is therefore recommended to set the device at maximum 55°C (energy-saving setting) in areas with extremely hard water >16°dH. | |
| Cleaning The housing of the device can simply be cleaned with a damp cloth. Do not use aggressive cleaners or cleaners with a scouring effect! | |
| Legionella prevention Do not use heated water as drinking water. After prolonged shutdown of the device for example due to holidays, the device should be fully heated up to the maximum temperature (tap at minimum flow) before re-using. It is recommended to flush the pipes for one minute. | |
