Note
Details identified by the word "Note" con-
tain additional information.
Installation, commissioning, inspection,
maintenance and repairs must only be
carried out by a competent person (heat-
ing engineer/installation contractor).
Before working on the equipment/heat-
ing system, isolate the power supply
(e.g. by removing a separate mains fuse
or by means of a main isolator) and safe-
guard against unauthorised reconnec-
tion.
Repairing components that fulfil a safety
function can compromise the safe oper-
ation of your heating system.
For replacements, use only original
spare parts supplied or approved by
Viessmann.
