f Flush the pipes thoroughly. f
The max. permissible pressure must not be exceeded (see chapter
"Specification / Data table").
ff Install a type-tested safety valve in the cold water supply
line. Please note that, depending on the static pressure, you
may also need a pressure reducing valve.
f Fit the DHW outlet pipe and the cold water inlet pipe. Con- f
nect the hydraulic connections with flat gaskets.

f Connect the cold water supply directly to the cylinder or with f
the connecting pipe routed between the cylinder feet.
f During fitting, counterhold the fitting with an open-ended f
spanner (size 36).
f Check the rigidity of the connecting pipe and secure it further f
if required.
ff Size the drain so that water can drain off unimpeded when
the safety valve is fully opened.

as a permanent connection in conjunction with the re-
movable cable entry. Ensure that the appliance can be
separated from the power supply by an isolator that dis-

!
Observe the type plate. The specified voltage must match
the mains voltage.
f Pull off the temperature selector. f
f Undo the screws at the bottom of the control panel cover and f
remove the cover.
f Prepare the power cable and feed it through the cable grom- f
met into the control panel. Select a cable with a cross-section
suited to the load of the appliance.
Note
If you connect the appliance for 3 kW output, two heating
elements are connected in series and the surface load is
reduced. This can significantly prolong the service life of
the electric heating elements, particularly in areas with
a water hardness level of 14 °dH or higher.
f Connect the required load in accordance with the connection f
examples (see chapter "Specification / Wiring diagrams and
connections").
f Fit the control panel cover. f
f Push on the temperature selector. f
f If the power supply utility does not permit rapid heating, f
cover the pushbutton with the plastic cap provided.
f Use a ballpoint pen to mark the selected connected load and f
voltage on the type plate.
