Operation instruction
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 DLX 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, 45 °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 happen 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).
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.

How to use

Temperature setting
The temperature selection key allows you to quickly select one of three preset temperatures, that are typical for hot water applications: “Hand wash” 35 °C, “Bath tub” 45 °C and “Cleaning” 55 °C.
Every key press sets the temperature to the next level: 35 °C 45 °C 55 °C
Pressing the key once again, starts the cycle all over.
The currently selected temperature is indicated by one of three coloured LEDs.
Power limit
If the full output of the instantaneous water heater DLX 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 appliance is again sufficient to reach the set temperature.
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.
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.

 Trouble-shooting and service

**** Repairs must only be carried out by authorised professionals.
If a fault in your appliance cannot be rectified with the aid of this table, please contact the service organisation of your importer or the Central CustomerService Department. Please have the details of the typeplate at hand.

• EN 806
• Installation must comply with all statutory regulations, as well as those of the local electricity and water supply companies.
• The rating plate and technical specifications
• Only intact and appropriate tools must be used

Installation site

• Appliance must only be installed in frost-free rooms. Never expose appliance to frost.
• The Appliance must be wall mounted and has to be installed with water connectors downward or alternative transversely with water connections left.
• The appliance complies with protection type IP25 and may therefore be installed in protection zone 1 according to VDE 0100 part 701 (IEC 60364-7).
• In order to avoid thermal losses, the distance between the instantaneous water heater and the tap connection should be as small as possible.
• The appliance must be accessible for maintenance work.
• Plastic pipes may only be used if they conform to DIN 16893, Series 2.
• The specific resistance of the water must be at least 1100 Ω cm at 15 °C. The specific resistance can be asked for with your water distribution company.

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. To open the appliance pull down the faceplate and unscrew the main hood screw.
   Lift the hood carefully, remove the plug from the control panel and note the position of the plug.

4. Loosen the knurled nut of the wall bracket, remove the wall bracket and screw it on 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.
• Put the water flow limiter “D” into the hot water connection piece. The O-ring must be visible

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 applyingforce.
  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.
  5. Next, open and close the hot water tapping valve several times until no more air emerges from the line and all air has been eliminated from the instantaneous water heater.

Direct connection

Note: Fasten the screw nuts with caution, to avoid damage to the valves or the piping system.
For direct connection, the two ½ inch screw-in nipples and the ½ inch seals must be screwed into the ½ inch union nuts of the hot-water and cold-water connectors. The two ½ inch caps of the side outlets of the hot-water and cold- water connectors must be removed and screwed onto the open end of the screw-in nipples. Put the water flow reducer “D” into the hot water connection piece. The hot-water and cold-water connectors must then be screwed into the ⅜ inch union nut of the appliance inlet and outlet pipe, together with the ⅜ inch seals.
For direct connection, it may be advisable to mount the appliance at a distance as illustrated alongside, using the spacer sleeves supplied. The two fixing holes near the lower pipe connections are also to be professionally fixed with 6 mm dowels and screws.
The flared end of the pipes must be screwed into the ½ inch side outlets of the hotwater and cold-water connectors with ½ inch union nuts and ½ inch seals.
The holes required for the pipes must then be opened of the housing with the aid of a blunt implement.
In case of direct connection please note: Put the strainer into the cold water connection!

Load shedding relay
If further three-phase appliances are connected, a load shedding relay designed for electronic instantaneous water heaters (CLAGE no. 82250) can be connected to phase conductor L2.
To avoid possible jitter of the load shedding relay caused by low power consumption (low temperature set point and low water flow rate) the “Load- shedding-mode” can be activated as followed:

• Disconnect the appliance from the power supply (e.g. by switching of the fuses)
• Take the jumper off the power electronics and change to position “1” (see picture).
• Put the appliance into operation again

Electrical connection from below
Note : If necessary, the connecting terminal can be displaced to the upper part of the appliance. If you want to do so, please follow the instructions in the next chapter.
Check that the power supply is switched off prior to electrical connection!

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 connecting 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 damaged! 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 connecting cables in such a way that the sleeve fits perfectly in the recess of the intermediate panel without mechanical tension and fix it with the sleeve fixing (A).
