7. Initial operation
STB
Multiple Power System MPS
®
The rated capacity (max. power con-
sumption) is 27 kW / 400 V and can be
changed internally to 24 kW, 21 kW or
18 kW.
Before making the electrical connection, fill the mains and the appliance with water
by carefully opening and closing the hot water tap in order to vent completely.
To ensure a maximum flow, remove any existing aerator from the faucet. Flush the
warm and cold water pipes each at least for one minute.
After every draining (e.g. after work on the plumbing system or following repairs to
SDB
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 pres-
sure cut-out may have tripped during transport. If necessary, check that the power
supply is switched off and reset the cut-out.
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 situa-
tion. 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 heat-
er" (see page 34).
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 set 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 to use the instan ta neous water heater and hand over the oper-
ating instructions.
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 26).
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 rat-
ing.
A temporary short-circuit of the two pins
acc. to EN 60900, will reset all heater parameters to works setting and lock the heat-
ing. 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.
