6. Electrical connection

Only by a specialist!
Please observe:
• e.g. VDE 0100
EN
• The installation must comply with current IEC and national local regulations or any particular
regulations, specified by the local electricity supply company
• The rating plate and technical specifications
• The appliance must be earthed!

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.

7. Initial operation

Vent the device according to the enclosed 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!
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. Start up the FX Next remote control according to steps 2-6 in chapter "3. Remote control"
section "Connecting the remote control to the instantaneous water heater" (see page
10).
3. After entering the Bluetooth PIN and successfully registering the remote control with the
instantaneous water heater, the menu for setting the output follows. If not, please follow the
section "Reinstallation".
4. Select the maximum allowable power rating depending on the local situation via remote
control (18, 21, 24 or 27 kW).
5. Press "OK" to confirm the setting.
6. Mark the selected power rating on the rating plate.
7. After having set the maximum allowable power rating, the heating element will be activated
after approx. 10 – 30 sec of continuous water flow.
8. Open the hot water tap. Check the function of the appliance.
9. Explain the user how the instan ta neous water heater works and hand over the operating
instructions to the user.
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 holder 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 holder 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.

10. Fill in the guarantee registration card and send it to the CLAGE After-Sales Service or use
the online regis tration on our website (see also page 9).
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 on the right (see figure F3), e.g. with a screwdriver
acc. to EN 60900, 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 a crossed out radio symbol. A keystroke restarts the registration.
Under those circumstances reduce the distance to the water heater and check whether the
power supply is turned on.
