1. Safety instructions

Please read these instructions carefully before installing or using the appliance!

Keep the instructions handy with the appliance for future use!

Instruction manuals are intended for the specialist who is responsible for the installa-

tion of the appliance. Operation manuals are for the end user. The provided manuals

correspond to the technical specifications of the appliance.

The latest version of the instructions can be found online at www.clage.com.

• Do not use the appliance until it has been correctly installed and

unless it is in perfect working order.

• Do not remove the front cover under any circumstances before switch-

ing off the mains electrical supply to the unit.

• Never make technical modifications, either to the appliance itself or

the electrical leads and water pipes.

• The appliance must be earthed at all times.

• Pay attention to the fact that water temperatures in excess of approx.

43°C are perceived as hot, especially by children, and may cause a

feeling of burning. Please note that the fittings and taps may be very

hot when the appliance has been in use for some time.

• The appliance is only suitable for domestic use and similar applica-

tions inside closed rooms, and must only be used to heat incoming

water from the mains supply.

• The appliance must never be exposed to frost.

• The values stated on the rating plate must be observed.

• In case of malfunction, disconnect the fuses immediately. In case of

leaks, cut off the mains water supply instantly. Repairs must only be

carried out by the customer service department or an authorised pro-

fessional.

• This appliance can be used by children aged 3years and above and

persons with reduced physical, sensory or mental capabilities or lack

of experience and knowledge if they have been given supervision or

instruction concerning use of the appliance in a safe way and under-

stand the hazards involved. Children shall not play with the appliance.

Cleaning and user maintenance shall not be performed by children

without supervision.

DEX ELECTRONIC MPS®

The instantaneous water heater DEX is a microprocessor-controlled, pressure-resistant

water heater for a decentralised water supply to one or more tap connections.

Its electronic control regulates the power consumption depending on the selected out-

let 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 fluc-

tuations. The required outlet temperature can be entered on a keypad within a range

between 20°C and 60°C and can be read off the digital display.

The maximum inlet temperature can be up to 70°C so that operation in connection

with solar heating 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 automatically. When the tap is closed, the appliance automatically switches

off.

Temperature setting

• You can set the required temperature gradually to a lower or higher value with the

arrow keys and . The temperature changes by 1°C if key is pressed shortly one

time. Pressing a key for a longer time changes the temperature continuously. You

can select the outlet temperature in a range from 20°C to 60°C.

Note: If temperature is set below 20°C with arrow key the display shows “--“

and the appliance switches off the heating function.

Note: If the water heater supplies a shower and is connected to a remote control

system, the maximum temperature was reduced during initial operation. This

limitation cannot be exceeded.

Programme buttons

The two programme buttons and allow to quickly select the preset temperature.

When pressing a programme key, the preset temperature is selected and displayed.

The factory setting for programme is 35°C and for programme 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 ”P1” or

“P2“ 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

The instantaneous water heater DEX is equipped with an optional temperature limit-

ing function. This scalding protection is deactivated in the factory setting.

• Switch on: Select the limit temperature, then press and simultaneously for at

least 3 sec. The display briefly confirms the activation by “HI“.

• Switch off: press program key

and simultaneously for at least 3 sec. The display briefly confirms the deactiva-

tion by “--“.

Note: By activation of the temperature limit also the programme keys are limited.

Therefore, the fixed values of the programme keys may be set again after deacti-

vation of the temperature limitation.

DEX ELECTRONIC MPS®

Reset to factory setting

All factory settings can be recalled:

• Press and simultaneously. The display now counts backwards from “10“ to

“00“ in second intervals. The appliance is reset at value “00“ - if you stop pressing

the keys earlier, you will cancel the process.

Reset

Press + hold!

Reset completed

3. How to use

Power limit

If the full output of the instantaneous water heater DEX does not suffice to heat the

tapped quantity of water, this will be indicated by the LCD decimal point (e.g. in winter

time, when opening several taps at once). When you reduce the hot water flow rate,

the LCD point stops indicating because the output of the appliance is again sufficient

to reach the set temperature.

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 out-

put, the flashing decimal point of the digital display indicates that the heating power

is switched off.

Unit provides no output

Power limit

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 cir-

cuitry, with the result that temperature constancy is no longer guaranteed.

How to save energy

3. How to use

This instantaneous water heater features an automatic air bubble protection to pre-

vent 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.

Venting after maintenance work

• 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 (special tap aerators 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

DEX ELECTRONIC MPS®

Repairs must only be carried out by

authorised professionals.

If a fault in your appliance cannot be

rectified with the aid of this table,

This instantaneous water heater was manufactured conscientiously and checked sever-

al times before delivery. Should malfunctions nevertheless occur, it is usually only due

to a bagatelle. 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 unnecessary expense of customer service assistance.
