> Put hemp on the two double nipples (2 and 6) and
use the connections to screw the double nipples to
the wall (1 and 7).
> Insert the seals (3) in the cap nuts of the cold (4) and
hot water connections (5).
> Screw the cold water connection piece (4) to the cold
water connection double nipple (2) in the wall (1).
> Screw the hot water connection piece (5) to the hot
water connection double nipple (6) in the wall (7).
> Insert a seal in the cap nut of the unit-side hot water
connection.
b
Caution.
Risk of damage due to pipes being blocked
by foreign bodies in the water.
A water filter that stops foreign bodies enter-
ing the unit must be fitted to the cold water
flow. The unit must not be used without a
water filter. A water filter has been fitted
inside the pipe at the factory.
> During installation, check that the water
filter is present.
> Check that the cold water filter fitted at the factory is
in the correct position in the unit-side cold water con-
nection. The cold water filter is an additional seal on
the cold water side.

Connecting the unit to the electricity supply

e
Danger!
Risk of death from electric shock from live
lines and connections!
> Isolate all supplies from the power supply
before carrying out electrical work.
> Check that there is no voltage in the supply
lines and connections.
> Ensure that the power cannot be restored
inadvertently to any of the supply lines and
connections while you are working on the
unit.
> When connecting the electricity supply, also observe
the local regulations from the electricity supply com-
pany as well as the specifications on the identification
plate.
> Also note the following conditions:
– The unit must be installed using a permanent con-
nection.
– The permanent connection must be equipped with
a customer-supplied partition that has a contact
separation of at least 3 mm on all lines. A line pro-
tection switch, for example, is suitable for this
purpose.
– The unit must be connected to the protective
earth.
– The unit is delivered pre-assembled. When connect-
ing the electricity supply, only the electricity line
needs to be fed in to the unit and connected. This
happens using one of the two anti-spray-water
sleeves that prevent water penetrating the unit;
see fig. 4.7, Cutting the anti-spray-water sleeve for
the cable routing. The connection is fixed to the
upper section of the unit at the factory. If required,
it can be connected to the lower section of the unit
but the electricity line must be fed through the
lower anti-spray-water sleeve.
4.6.1

Electrical connection from above

The electricity line is fed through the upper anti-spray-
water sleeve (see (2) in fig. 4.12). Figure 4.7 explains how
the anti-spray-water sleeve must be prepared.
> Connect the individual conductors to L1, L2 and L3,
and the protective earth to the mains connection ter-
minal (1 in fig. 4.12).
