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. Close the shut-off valve (a) in the cold water connection piece (position "0" fig. G1).
3. Unscrew the screw plug (b) from the cold water connection piece and take out the strainer
(c) (fig. G2).
Note: Residual water can leak
4. The strainer can now be cleaned or re placed.
5. After fitting of the clean strainer tighten the screw plug.
6. Slowly reopen the shut-off valve in the cold water connection piece (position "1"). Check all
connections for leaks.
7. 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.
8. Then switch on the power again (e.g. via activating the fuses).
