10. Preparing for installation

10.1 Preparing to install the appliance

The wall mounting brackets attached to the appliance have hook-
in slots, which in most cases enable installation on the bolts that
are already in place from previous appliances.
f Otherwise, transfer the dimensions for the holes to be drilled f
on the wall (see chapter "Specification / Dimensions and
connections").
f Drill the holes, if required, and secure the wall mounting f
brackets with screws and rawl plugs. Select fixing materials
in accordance with the wall construction/condition.
f Hook the appliance with wall mounting brackets on to the f
screws or bolts. Observe the weight of the appliance when
empty (see chapter "Specification / Data table") and, if neces-
sary, ask another person to help.
f Align the appliance vertically or horizontally. f

cordance with regulations.
Cold water line
Steel or copper pipes or plastic pipework are approved materials.
DHW line
Copper or plastic pipework are approved materials.
Material damage
!
When using plastic pipework, observe chapter "Specifica-
tion / Fault conditions".
Note
If the water pressure is higher than 0.6 MPa, install a
pressure reducer in the "cold water inlet".
Operate the appliance only with pressure-tested taps.
f Thoroughly flush out the cold water line before connecting f
the appliance, so that no foreign matter gets into the water
heater or safety valve.
f Connect the hydraulic connections with flat gaskets. f
f Route the safety valve drain line to a drain free from the risk f
of frost, with a continuous downward slope to ensure the un-
restricted flow of the water to the drain. The discharge aper-
ture of the safety valve must remain open to the atmosphere.
