E-compact instant water heater
CEX-U/CEX

Note: Carefully read the enclosed safety instructions in full before using the appliance and follow them during use!

The documents supplied with the device must be stored carefully.

Description of the appliance

The instantaneous water heater CEX-U / CEX is an electronically controlled, pressure-resistant water heater for a decentralized hot water supply to one or more outlets.
It’s electronic control regulates the heating 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 on a keypad and can be read off the digital display.

How to use

As soon as you open the hot water tap, the instantaneous water heater switches on automatically. When the tap is closed, the appliance automatically switches off.

Temperature setting

Set temperature

Convenience zone 35,0..42,0 °C

You can set the required temperature gradually to a lower or higher value with the arrow keys and .
The temperature changes by 1 °C, in the convenience zone between 35 °C and 42 °C by 0.5 °C, if the key is pressed shortly one time. Pressing a key for a long time changes the temperature continuously.
Note: If the temperature is set below 20 °C with an arrow key the display shows “–“ and the appliance switches off the heating function.
Note: If the water heater supplies a shower, the maximum temperature was reduced during the initial operation. This limitation cannot be exceeded.

Programme buttons

Select preset temperature

Store temperature

The two programme buttons allow to quickly select the preset temperature. When pressing a programme key, the preset temperature is selected and displayed. The factory setting for the programme (1) is 35 °C and for programme (2) it is 48 °C. You can assign your own settings for the programme keys:

• Prolonged pressing of the programme key stores the previously selected temperature. The display changes from ” ” or ” ” to the newly stored temperature value. This newly set temperature is now available to you each time you press the corresponding program key.

Temperature limitation

Temperature limit on

Temperature limit off

This instantaneous water heater is equipped with an optional temperature limiting function. This scalding protection is deactivated in the factory setting.

• Switch on: Select the limit temperature, then press (2) and  ****simultaneously for at least 3 sec. The display briefly confirms the activation by ” “.
• Switch off: press program key (1) and simultaneously for at least 3 sec. The display briefly confirms the deactivation by “–“.

Note: By activation of the temperature limit also the programme keys are affected. Therefore, the fixed values of the programme keys must be checked after changing the temperature limitation.

Reset to factory setting

Reset

All factory settings can be recalled:

• Press ****and simultaneously. The display now counts backwards from ” ” to ” ” in second intervals. The appliance is reset at value ” ” – if you stop pressing the keys earlier, you will cancel the process.

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.

ECO mode

The symbol shows that the appliance works in an energy-saving mode (i.e. the momentary energy consumption is subject to the selected temperature and to the flow rate in the energy-saving mode.

Power limit

If the full output of the instantaneous water heater does not suffice to heat the tapped quantity of water, this will be indicated by on the LCD (e.g. in the winter time, when opening several taps at once). When you reduce the hot water flow rate, stop lighting because the output of the appliance is sufficient to reach the set temperature again.

Top-up heating

The unit provides no output

When operating with preheated water (e.g. with solar systems), ensure that the maximum inlet temperature is not exceeded.
If the inlet temperature exceeds the setpoint, the icon on the digital display indicates that the heating power is switched off.

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 showerheads) 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 the 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 Customer Service Department. Please have the details of the type plate at hand.

This instantaneous water heater was manufactured conscientiously and checked several times before delivery. Should malfunctions nevertheless occur, it is usually only due to a bagatelle. The First attempt to switch the house fuses off and on again in order to reset the electronics. Next, try to remedy the problem with reference to the following table. In doing so, you will avoid the unnecessary expense of customer service assistance.

Problem

| Cause|

Solution

---|---|---
Water stays cold, the digital display does not light up| Master fuse tripped| Renew or activate the fuse
Safety pressure cut-out tripped| Contact customer service
Water stays cold, the digital display does light up| Safety thermal cut-out tripped| Contact customer service
The display flashes the error message ” “| The Control system has switched off| Switch fuse off and on. If ” ” still flashes contact cus­tomer service
The flow rate of hot water is too weak| Outlet fitting dirty or calcified| Clean showerhead, jet regu­lator or sieves
Fine filter dirty or calcified| Let clean fine filter by a spe­cialist
The selected temperature is not reached, “MAX” lights| Water flow rate too high| Reduce water flow rate at the tap
Selected temp. is not reached, “MAX” does not light| Coldwater has been added via the tap| Tap hot water only; set temperature for use
The symbol “sun” lights up| Inlet temperature exceeding the nominal temperature| Reduce inlet temperature
Appliance heats, the display does not light| Display plug, not properly connected| Let’s fix the correct position of the display plug by customer service

If the connection cable is damaged, it must be replaced with an original spare cable from the manufacturer by an authorised technician in order to avoid any hazards.
