Safety instructions
Please follow these safety instructions closely to prevent accidents and
material losses
Safety instructions explained
Note Details identified by the word “Note” contain additional
information.
Installation, commissioning, inspection, maintenance and repairs must only be carried out by an authorised, competent person (heating engineer/installation contractor).
Before working on the appliance/heating system, isolate it from the power supply (e.g. by removing a separate mains fuse or by means of a mains isolator) and safeguard against unauthorised reconnection.
Wear suitable personal protective equipment when carrying out any work.
Repairing components that fulfil a safety function can compromise the safe operation of the system. For replacements, use only original spare parts supplied or approved by Viessmann. Install the components with new gaskets.
