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
EN
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.
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. Select the maximum allowable power rating depending on the local situation. To do this,
take the auxiliary tool "A" from the holder on the electronics cover and turn the switch to
the desired value (fig. F3).

7. Maintenance work

Maintenance work must only be conducted by an authorised professional.
Cleaning and replacing the filter strainer
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, pull down the faceplate and unscrew the main hood screw. Lift the
hood carefully, remove the plug from the control panel and note the position of the plug.
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. Connect the control panel cable to the control panel in the hood, replace the hood and
tighten the hood screw.
Note: The control panel cable must not be pinched or squeezed.
Then switch on the power again (e.g. via activating the fuses).

2. Put the auxiliary tool back into the holder, connect the control panel cable to the control
panel in the hood, place the hood on the appliance and fix it with the hood screw.
Note: The control panel cable must not be pinched or squeezed.
3. Mark the selected power rating on the rating plate and slide on the faceplate from the bot-
tom up to the stop.
4. Switch on the power supply to the appliance.
5. After having set the maximum allowable power rating, the heating element will be activated
after approx. 10 – 30 sec of continuous water flow.
6. Open the hot water tap. Check the function of the appliance.
7. Explain the user how the instantaneous water heater works and hand over the operating
instructions.
8. Fill in the guarantee registration card and send it to the CLAGE Central Customer Service or
use the online registration (see page 7).
Note: Each time the supply voltage is switched on, the set power is indicated by the LED on the
power unit flashing and lighting up.
Note: Operating panel lock

Cleaning and replacing the filter strainer if direct connected
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, pull down the faceplate and unscrew the main hood screw. Lift the
hood carefully, remove the plug from the control panel and note the position of the plug.
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 (fig. G3).
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.
