Maintenance and Cleaning
Check proper functioning of the safety valve every two months by opening and closing the test lever. The
heating element should be checked annually for scale formation, caused by impurities in the water supply.
Also, the anode should be checked annually and replaced when worn out over 60%. For cleaning the
element or replacing the anode, use the following procedure:
1.
Switch off the electric supply to the water heater.
2.
Open the hot water taps until the water is not hot any more.
3.
Close cold water supply.
4.
Drain the water heater by removing the safety valve in the direction
of the arrow as indicated in the diagram shown alongside and open the hot water taps.
5.
Take off the water heater from the hanger hook when the water heater is empty.
6.
Remove the decorative front panel, unscrew the heating assembly flange.
7.
Clean the container and the heating element assembly from scale by using a suitable acid or by gently
scraping the scale.
8.
Replace anode, if required.
9.
Remount the heating assembly flange.
10. Hang the water heater on the hanger hook on the wall through the 2 holes of its mounting bracket.
Move the water heater downward to ensure that the holes are pressed against the root of the hanger
hooks, and ensure the water heater is fixed steadily.
11. Open cold water supply until water flows without interruption from hot water faucets.
12. Close the hot water taps and check for eventual leakage around the flange.
13. When there is no leakage, replace the decorative front panel. Then switch on electric supply.
