Handing over to the operator

a
Danger!
Risk of being scalded by hot water!
Above a water temperature of 43 °C, there is
a risk of scalding. When setting the output
regulator to level II, temperatures can reach
up to 60 °C.
> Inform the operator that there is a risk of
scalding above a water temperature of
43 °C.
> Recommend to the operator that, in normal
operating mode, the output selector is set
to level I to avoid scalding.
You must inform the operator of the unit about the han-
dling and function of their VED.
> Provide the operator with all relevant instructions and
unit documentation for safe-keeping.
> Go through the instructions for use with the operator.
> Answer any questions the operator may have.
> Draw special attention to the safety information
which the operator must follow.
> Inform the operator of the necessity to ensure that the
system is regularly inspected/maintained by a compe-
tent person (inspection and maintenance contract).
> Make the operator aware that the instructions should
be kept near the VED.

Replacement parts and accessories

The original components of the unit were also certified
as part of the CE declaration of conformity. If you do not
use certified Vaillant genuine spare parts, this voids the
CE conformity of the unit. We therefore strongly recom-
mend that you fit Vaillant genuine spare parts.
You can find information about available Vaillant genu-
ine spare parts from the contact address provided on
the reverse of this document.
> If you require spare parts for servicing or repair work,
use only Vaillant genuine spare parts.
