1. Description of the appliance

As soon as you open the hot water tap, the instantaneous water heater switches on auto ma ti cally. When the tap is closed, the appliance automatically switches off. The E-convenience instant water heater DCX Next / DCX 13 Next is a electronically controlled pressure-resistant instantaneous water heater for an efficient water supply to one or more tap outlets. Its electronic control regulates the power consumption depending on the selected outlet temperature, the respective inlet temperature and the flow rate, thus reaching the set temperature exactly to the degree and keeping it constant in case of water pressure fluctuations. The outlet temperature can be set to 35 °C, 38 °C, 42 °C, 48 °C or 55 °C using the central sensor key. In case of a low feed temperature and a high flow rate at the same time, it could hap- pen that the preset outlet temperature is not reached which is due to the fact that the appliance exceeded its capacity. The outlet temperature can be raised by reducing the water flow at the tap. It is possible to use the instantaneous water heater in combination with an external load shedding relay for electronically controlled instantaneous water heaters (refer to installing instructions). This product was manufactured climate neutrally according to Scope 1 + 2. We recommend the purchase of 100% green electricity to make the operation climate neutral as well. Your product was manufactured from high-quality, reusable materials and components.

Temperature setting The temperature selection key allows you to quickly select one of five preset tem- peratures, that are typical for hot water applications: “Hand wash” 35 °C, “Shower” 38 °C, “Bath tub” 42 °C, “Kitchen” 48 °C and “Cleaning” 55 °C. Every key press sets the temperature to the next level: 35 °C 38 °C 42 °C 48 °C 55 °C Pressing the key once again, starts the cycle all over. The currently selected temperature is indicated by one of five coloured LEDs.

Temperature selection key Five coloured LEDs Device information Press and hold the temperature selection key for 10 seconds to open the info mode. After ten seconds, all LEDs light up once briefly and then switch off again immediately to confirm that the info mode is active. The device status is displayed via the LEDs: LED bottom left: OFF = no water flow; FLASHING = water flow below switch-on point; ON = water flow above switch-on point. LED top middle: ON = heating active; FLASHING = power limit. Otherwise OFF. LED bottom right: OFF = device OK; FLASHING = error detected (inform customer service) The display returns to normal operation after 60 seconds or after a key press. Power limit If the full output of the instantaneous water heater DCX Next does not suffice to heat the tapped quantity of water, this will be indicated by flashing of the temperature LED (e.g. in winter time, when open ing several taps at once). When you reduce the hot water flow rate, the LED lights up continuously again because the output of the appli- ance is again sufficient to reach the set temperature.CLAGE

• Plastic surfaces and fittings should only be wiped with a damp cloth. Do not use abrasive or chlorine-based cleaning agents or solvents.

• For a good water supply, the outlet fittings (e.g. jet regulators and shower heads) should be unscrewed and cleaned at regular intervals. Every three years, the electri- cal and plumbing components should be inspected by an authorised professional in order to ensure proper functioning and operational safety at all times. Cleaning and maintenance This instantaneous water heater features an automatic air bubble protection to prevent it from inadvertently running dry. Nevertheless, the appliance must be vented before using it for the first time. Each time the appliance is emptied (e.g. after work on the plumbing system, if there is a risk of frost or following repair work), the appliance must be re-vented before it is used again.

1. Dismantle approximately 6 cm off the connecting cable above the wall outlet. With

the smaller opening ahead, slide the water splash protection sleeve over the con- necting cable so that the sleeve is flush with the wall. This prevents any leaking water from coming into contact with the electrical leads. It must not become dam- aged! The protection sleeve must be used!

2. Strip the individual wires and plug them in the connecting terminals according to

the wiring diagram. The appliance must be earthed.

3. Pull the protective sleeve so far over the connecting cables and shape the connect-

ing cables in such a way that the sleeve fits perfectly in the recess of the intermedi- ate panel without mechanical tension and fix it with the sleeve fixing (A). Electrical connection from below Electrical connection from above

Before making the electrical connection, fill the mains and the appliance with water by carefully opening and closing the hot water tap in order to vent completely. To ensure a maximum flow, remove any existing aerator from the faucet. Flush the warm and cold water pipes each at least for one minute. After every draining (e.g. after work on the plumbing system or following repairs to the appliance), the heater must be re-vented in this way before starting it up again. If the water heater cannot be put into operation, the temperature cut-out or the pres- sure cut-out may have tripped during transport. If necessary, check that the power supply is switched off and reset the cut-out. Selection of power rating Only by authorised specialist, otherwise lapse of guarantee! Before first connection of the appliance to the supply voltage, select the maximum power rating. The maximum allowable power rating at installation site depends on the local situa- tion. It is imperative to observe all data shown in the table “Technical specifications”, in particular the required cable size and fuse protection for the electrical connection. Moreover, the electrical installation must comply with the statutory regulations of the respective country and those of the local electricity supply company (Germany: DIN VDE 0100).
