Maintenance And Cleaning; Descaling - Kerbl C 10 Mode D'emploi

Caution!
Before removing the sealing cap or opening the housing, disconnect the circulation pump from the mains voltage!
Temperature controller (TR):
• Remove the sealing cap on the front of the housing.
• The temperature value can be adjusted with a screwdriver.
• Stop left: ~ 5 °C
• Stop right: ~ 35 °C
Safety temperature limiter (STB):
• The STB is not accessible from the outside.
• The heating element may only be opened by an authorised specialist.
• The STB should not be reset without a thorough fault analysis.
• Before resetting, the heating element must cool down.
• In general, we recommend replacing the heating element.
Important!
Changing the factory-set temperature can have the following effects:
• Increased limescale build-up due to an increase in flow temperature. Maintenance requirements are increased and the service life of the heating
element is reduced.
• Increased energy consumption.
• A temperature that is set too low can cause pipes and drinking bowls to freeze.

8. Maintenance and cleaning

Caution!
• Maintenance work may only be carried out by an authorised specialist.
• For any kind of maintenance and cleaning work, the entire C10 circulation pump must be disconnected from
the mains voltage and secured against being switched on again.
• The circulation pump must never be operated without water.
Doing so will cause irreparable damage to the pump as well as the heating element.
• During maintenance or service work on water-bearing parts of the unit. Hot water may leak out.
Hot water may escape during ventilation. Hot surfaces are not always obvious.
Important!
To maintain continuous performance of the unit, the water circuit must be operated with clean water. All water precipitates limescale at high
temperatures. This settles on the heating coils of the heating element and affects the unit's function and service life. In the case of hard water
(>14°dH), we recommend installing a descaling system upstream of the water circuit.

8.1 Descaling

1. Disconnect the circulation pump from the mains voltage and secure it against being switched on again.
2. Close the shut-off valve (item 7) before and after the C1- circulation pump and open the shut-off valve on the bypass pipe (item 8).
