The cold water connection of this instantaneous water heater is equipped with an inte-
grated 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 posi-
tion of the plug.
3. Close the shut-off valve (a) in the cold water connection piece (position “closed“).
4. Unscrew the screw plug (b) from the cold water connection piece and take out the
strainer (c).
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 (posi-
tion “open“). Ensure that there are no leakages.
8. Vent the appliance by carefully opening and closing the affiliated warm water tap
valve several 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).
Maintenance work must only be conducted by an authorised professional.
