Operating Instructions and Installation Instructions
ENGLISH
7. Safety
7.1 General safety instructions
All required steps to complete commissioning must be carried
out by a heating contractor. During this process, these installation
instructions must be observed.
We guarantee trouble-free function and operational reliability
only if the original accessories and spare parts intended for the
appliance are used.
7.2 Instructions, standards and regulations
!
Material damage
Observe the type plate. The stated voltage must match
the mains voltage.
WARNING Risk of electrocution
All electrical connection and installation work must
be conducted in accordance with VDE regulations
(DINVDE0100) [or local regulations], the rules of your
local power supply utility and relevant national and local
regulations.
WARNING Risk of electrocution
Connection to the power supply is only possible as
a fixed connection. The appliance must be able to be
separated from the mains power supply by an isolator
that disconnects all poles with at least 3 mm contact
separation.
Note
Observe all national and local instructions and regulations
relating to water connection.
- The protection IP 25 (hoseproof) can only be ensured with a
correctly fitted cable grommet.
- The specific electrical resistant of the water used must not
fall below that stated on the type plate. In a linked water
network, observe the lowest electrical water resistance
(see chapter "Application areas"). Your water supply utility
will advise you of the specific electrical water resistance or
conductivity.
7.3 Water installation
7.3.1 Cold water line
Permissible materials: Galvanised steel pipe, stainless steel pipe,
copper pipe or plastic pipe.
7.3.2 DHW line
Permissible materials: Stainless steel pipe, copper pipe or plastic
pipe.
!
Material damage
If plastic pipework is used, observe the most extreme
operating and fault conditions that can occur in the
appliance.
Note
Observe the plastic pipe manufacturer's instructions.
- A safety valve in the hot water pipe is not permissible.
- Never operate with valves intended for open vented
appliances.
7.4 Risk of frost
The installation of the appliance must be carried out in a room
free from the risk of frost.
Store the dismantled appliance in a room free from the risk
of frost, as water residues remaining inside the appliance can
freeze and cause damage.
