Structural prerequisites
•
The appliance must be installed via a permanent connection. Heater must be earthed!
•
The electric wiring should not be injured. After mounting, the wiring must not be direct
accessible.
•
An all-pole disconnecting device (e.g. via fuses) with a contact opening width of at least
3 mm per pole should be provided at the installation end.
•
To protect the appliance, a fuse element must be fitted with a tripping current commensu-
rate with the nominal current of the appliance.
6. Initial operation
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 selected 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. Start up the FX3 remote control according to steps 2-6 in chapter "3. Remote control" sec-
tion "Connecting the remote control to the instantaneous water heater" (see page 12).
Electrical connection from below
Note: If necessary, the connecting terminal can be displaced to the upper part of the appliance.
To do this, please follow the instructions in the operating and installation manual available online.
Check that the power supply is switched off prior to electrical connection!
1. Remove the outer sheath of the connection cable from about 6 cm above the wall outlet (fig.
E2). With the smaller opening ahead, slide the water splash protection sleeve over the con-
necting 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. Open the control panel rightwards.
3. Strip the cables and plug them in the connecting terminals according to the wiring diagram.
The appliance must be earthed.
4. Pull the protective sleeve over the connecting cables until the sleeve fits perfectly in the
recess of the intermediate panel. Adjust the water splash protection sleeve as illustrated and
fix it with the sleeve fixing (A). Reinsert the control panel and lock it on (fig. E3).
5. Place the hood on the appliance and screw in the fastening screw. After that you can slide
on the faceplate from the bottom up to the stop.

9. Explain the user how the instantaneous water heater works and hand over the operating
instructions.
10. 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 10).
Reinstallation
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
ure 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.
Shower application
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.
Notes in case of remote control connection problems
In case of a failing connection between the remote control and the water heater, the display
indicates "E1". A keystroke restarts the registration.
Under those circumstances reduce the distance to the water heater and check whether the
power supply is turned on.
