Safety instructions
Please note
Repairing components that fulfil a
safety function can compromise
the safe operation of your sys-
tem.
Replace faulty components only
with original Viessmann spare
parts.
Please note
Spare and wearing parts that
have not been tested together
with the system can compromise
its function. Installing non-author-
ised components and making
non-approved modifications or
conversions can compromise
safety and may invalidate our
warranty.
For replacements, use only orig-
inal spare parts supplied or
approved by Viessmann.
Please note
The blow-down and T.D.S. water
from boiler systems can reach
temperatures of 100 °C and
higher.
Set up the system so that this
water is cooled down to < 35 °C
prior to it entering the sewer sys-
tem. Where necessary, refer to
the local water authority.
