The operating mode of the appliance can be restricted.
Activation of the locking function
1. Select required parameters via the setting menu (see online user manual chapter “Settings”,
subpoints “Temperature limit” and / or “Load shedding”).
2. Disconnect the appliance from the power supply (e.g. by switching off the fuses).
3. Take the jumper off the power electronics and change to position “
1” (see figure F5).
4. Put the appliance into operation again.
Deactivation of the locking function
1. Disconnect the appliance from the power supply (e.g. by switching off the fuses).
2. Take the jumper off the power electronics and change to position “
0” (see figure F5).
3. Put the appliance into operation again.
6. Initial operation
In case the appliance will be commis sioned again under different installation conditions than
during its initial ope ration, it may be necessary to adapt the maximum power rating.
A temporary short-circuit of the two pins on the right, e.g. with a screwdriver acc. to EN 60900
(see figure F4), will reset all heater parameters to works setting and lock the heating. The display
shows the menu to select the language. Choose your language, after that the selection of power
rating appears. This condition will maintain when activating and deactivating the supply voltage.
Reinstallation
The water heater’s temperature must be limited to 55 °C, if it is connected to a shower. The tem-
perature limit must be set to a value less or equal 55 °C in the setting menu, in consultation with
the customer and the lock level must be activated.
When the appliance is operated with preheated water, it must be ensured that this temperature
is limited to 55 °C as well.

Maintenance work must only be conducted by an authorised professional.
7. Maintenance work
The cold water connection of this instantaneous water heater is equipped with an integrated
shut-off valve and a strainer. Soiling of the strainer may reduce the warm water output. Clean or
replace the strainer as follows:
1. De-energize the instantaneous water heater (e.g. via deactivating the fuses) and prevent
inadvertent reactivation of them.
2. To open the appliance, take off the small face plate, loose the screw behind this cover and
detach the hood.
3. Close the shut-off valve (a) in the cold water connection piece (position “0“ fig. G1).
4. Unscrew the screw plug (b) from the cold water connection piece and take out the strainer
(c) (fig. G2).
Note: Residual water can leak
5. The strainer can now be cleaned or re placed.
6. After fitting of the clean strainer tighten the screw plug.
7. Slowly reopen the shut-off valve in the cold water connection piece (position “1“). Check all
connections for leaks.
8. Vent the appliance by carefully opening and closing the affiliated warm water tap valve sev-
eral times until air no longer emerges from the pipe.
9. Fit the hood of the appliance. Then switch on the power again (e.g. via activating the fuses).
Cleaning and replacing the filter strainer
The cold water connection of this instantaneous water heater is equipped with a strainer. Soiling
of the strainer may reduce the warm water output. Clean or replace the strainer as follows:
1. De-energize the instantaneous water heater (e.g. via deactivating the fuses) and prevent
inadvertent reactivation of them.
2. Close the shut-off valve in the mains water supply of the instantaneous water heater.
3. To open the appliance, take off the small face plate, loose the screw behind this cover and
detach the hood.
4. Unscrew mains water inlet from connection piece and take out the strainer.
Note: Residual water can leak
5. The strainer can now be cleaned or replaced.
6. After refitting the clean strainer reconnect the mains water inlet to the connection piece.
7. Slowly reopen the shut-off valve in the mains water supply. Check all connections for leaks.
8. Vent the appliance by carefully opening and closing the affiliated warm water tap valve sev-
eral times until air no longer emerges from the pipe.
9. Fit the hood of the appliance. Then switch on the power again (e.g. via activating the fuses).
Cleaning and replacing the filter strainer if direct connected
(fig. G3).
Fill the mains and the appliance with water and emerge air according to
image manual.
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 pressure cut-out
may have tripped during transport. If necessary, check that the power supply is switched off and
reset the cut-out (fig. F1 + F2).
Selection of power rating
Only by authorised specialist, otherwise lapse of guarantee!
On delivery, the display shows the screen “APPROVED” (see fig. F3). If not, the device has
already been powered once. In this case, please follow the section “Reinstallation”.
Upon first connection of the appliance to the supply voltage, select the maximum power rating.
Only after having set the power rating, the heater provides its standard operation mode.
The maximum allowable power rating at installation site depends on the local situation. 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).
1. Switch on the power supply to the appliance.
2. When switching on the supply voltage for the first time, the display shows the menu to
select the language. Choose your language, after that the selection of power rating appears.
3. Select the maximum allowable power rating depending on the local situation via sensor keys
(18, 21, 24 or 27 kW).
4. Select “
OK” to confirm the setting.
5. Mark the set power rating on the rating plate.
6. After having set the maximum allowable power rating, the heating element will be activated
after approx. 10 – 30 sec of continuous water flow.
7. Open the hot water tap. Check the function of the appliance.
8. Explain the user how the instantaneous water heater works and hand over the operating
instructions.
9. Fill in the guarantee registration card and send it to the CLAGE Central Customer Service or
use the online registration at our home page (see page 8).
