Note: Carefully read the enclosed safety instructions through in full before the appliance is installed, put into service and used and follow them in the further steps and during use!

Description of the appliance

The E-convenience instant water heater DEX Next S is a fully electronically controlled instantaneous water heater graphics-enabled e-paper display and sensor keys for a convenient and 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 pressure fluctuations. The required outlet temperature can be entered via the sensor keys within a range between 20 °C and 60 °C and can be read off the e-paper display. Alternatively, the appliance can be conveniently controlled via the Bluetooth® remote control or with the CLAGE app via smartphone and tablet.
The DEX Next S has an intuitive menu guide where different user profiles can be set up and where collected data can be read out
The inlet temperature can be up to 70 °C so that operation in connection with reheating, e.g. in solar systems, is possible.
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).
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 water heater is operated with the wireless remote control or via the CLAGE app with a smartphone or tablet.

Main menu
Press the menu button to enter the main menu. All function menus and saved values of the appliance can be selected from here.

Automatic
In this menu, two functions can be selected. Automatic either measures the time in seconds via the function “Duration” or the flow of heated water in litres via the function “Fill-Up”. Cold water added at the tap cannot be recorded by the appliance. In order to use the Automatic function correctly according to the fill quantity, it is therefore necessary to set the desired temperature and only turn on the hot water tap. For each function per user profile, the last set start value is saved and can be activated at any time.

Note: In Automatic mode, the operating functions are limited. When selecting a limited function, an instruction window appears. Select “OK” to deactivate Automatic mode and all functions are freely available again. Tap on “Cancel” to close the instruction window and Automatic mode remains active.
Duration: Under “Duration”, set the desired time and then select “Start” to activate Automatic mode. The view changes to the main control where the set time is displayed to the right of the temperature display. Turn on the hot water tap to start the function and the time starts to count down as seconds. Turning off the tap does not pause the function. If hot water is already flowing whilst the function is activated, it starts immediately. To cancel the function, tap on menu button and confirm the message with “OK”. When the time has elapsed, a message appears. In addition, the flow quantity, if it is being drawn, is reduced for around 10 seconds and then increased again.

Fill-Up: Under “Fill-Up” set the desired water quantity and then select “Start” to activate Automatic mode. The view changes to the main control where the set quantity is displayed to the right of the temperature display. Turning on the hot water tap starts the function and the set fill quantity counts down in litre increments according to the flow measurement. Continued turning off and on of the tap pauses and restarts the function. If hot water is already flowing whilst the function is activated, it starts immediately. To cancel the function, tap on menu button and confirm the message with “OK” or turn off the water flow for a minute.
When the fill quantity is reached, a message appears on the display and the appliance stops the water flow by closing the motor valve. The motor valve stay closed until the message is confirmed at the appliance, remote control or via app. Turning off the tap is always necessary, the function must therefore not be used unsu- pervised. Before using the bath, make sure that the water temperature is what you want it to be.
Hint : The water amount of the last draw-off is stored in the “Statistics” menu. To determine the necessary amount of water for your bathtub, fill it with warm water, then select “Statistics” in the main menu and read out the value of this last drawing. Enter this value in the automatic function “Fill-Up” to use it for the next bathtub filling.
Note: In the event of a power cut whilst the automatic is running according to the fill quantity, the water flow is stopped by the motor valve. After power is restored the valve remains closed a prompt appears on the display until the prompt is acknowledged by tapping on “OK”.

“ECO” flow rate limitation to max. 8.0 l/min
e.g. “9.0” limitation to a freely selectable value between 4.5 and 25 l/min When the economy function is active, the flow is limited to 8 l/min and the temperature is set to 38 °C.
Top-up heating
When operating with preheated water (e.g. with solar systems), you must ensure that the inlet temperature does not exceed 70 °C.
If the inlet temperature exceeds the setpoint, the appliance is not providing any output.
The symbol  is displayed in the main screen
How to save energy
Set the exact temperature you need on the appliance and open the hot water tap. Once you feel that the water is too hot, do not add any cold water and, instead, enter a lower temperature on the appliance. If you were to add cold water, the water already heated would cool down again and valuable energy would be wasted. Moreover, the cold water added in the tap is not covered by the control range of the electronic circuitry, with the result that temperature constancy is no longer guaranteed.
Venting after maintenance work
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. Disconnect the instantaneous water heater from the mains (e.g. via deactivating the fuses).
2. Unscrew the jet regulator on the outlet fitting and open the cold water tap valve to rinse out the water pipe and avoid contaminating the appliance or the jet regulator.
3. Open and close the hot water tap until no more air emerges from the pipe and all air has been eliminated from the water heater.
4. Only then should you re-connect the power supply again (e.g. via activating the fuses) to the instantaneous water heater and screw the jet regulator back in.
5. The appliance activates the heater after approx. 10 seconds of continuous water flow.

Cleaning and maintenance

• 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 electrical and plumbing components should be inspected by an authorised professional in order to ensure proper functioning and operational safety at all times.

• Do not install the device in the immediate proximity of metal surfaces to allow a reliable wireless connection and an optimal wireless range.

Installing the wall bracket
Note: If you install this instantaneous water heater in exchange for a conventional instantaneous water heater, there is generally no need to drill holes for the wall bracket, in this case step 2 would not be necessary.
Thoroughly rinse the water supply pipes before installation to remove soiling from the pipes.

1. Using a 12 mm hexagon socket screw key, screw the screw-in nipples into the wall connections. The seals must be fully screwed into the thread. After tightening, the double nipples must protrude by 12 – 14 mm.
2. Hold the included mounting template on the wall and align it so that the holes in the template fit over the double nipples. Mark the drill holes according to the template and drill them using a 6 mm drill. Insert the included dowels.
3. Pull down the faceplate and unscrew the main hood screw to open the appliance.
4. Loosen the knurled nut to remove the wall bracket and screw the wall bracket to the wall. Offset tiling or uneven surfaces can be compensated by up to 30 mm with the aid of the spacers supplied. The spacers are fitted between the wall and the wall bracket.

Installing connection pieces
Note: Fasten the screw nuts with caution, to avoid damage to the valves or the piping system.

• As shown in the illustration, screw the cold water connection piece with the union nut and the ½ inch seal onto the cold water connection.
• Screw the hot water connection piece with the union nut and the ½ inch seal onto the hot water connection.

Installing the appliance

• The electrical power supply cable may be connected in the upper part or is surface mounted. Only in such case, first follow the steps one through three according to the description “Electrical connection from above” in chapter “Electrical connection”.

1. Place the appliance on the heater bracket so that the threaded rod of the wall bracket fits in the corresponding hole of the appliance. If necessary, slight corrections are possible by carefully bending the threaded rod of the wall bracket. However, it must be possible to screw on the water connection pipes of the appliance without applying force.

2. Screw the plastic knurled nut onto the threaded rod of the wall bracket.

3. Screw the two ⅜ inch union nuts of the appliance‘s water connection pipes, each with the ⅜ inch seal, onto the fittings.
   
   

4.  Open the water supply line to the unit and slowly open (position “open“) the shutoff valve (a) in the cold water connection piece. Check all connections for leaks.
