Maintenance and decommissioning [specialist]
Before maintaining and decommissioning the product, you must read and observe the following safety instructions:
Risk of electric shock!
Disconnect all electrical devices in
the heating circuit from the power
supply before carrying out
maintenance work or
decommissioning!
Secure the electrical devices
against being switched on again.
Risk of burns and scalding!
The valves and fittings may heat up
