Wall mounting
There are two ways in which the continuous-flow heater can
be mounted on the wall:
– Using the mounting bolt. Unevenness in the wall up to a
depth of 25 mm can be compensated for.
– Making use of the holes that were drilled for the old heater:
Use the mounting template to establish whether the exist-
ing holes line up properly.
The following describes the installation procedure using the
mounting bolt.
Marking the point for mounting the heater and selecting
the opening for the connecting cable (Fig. A)
Important!
Make sure that the connecting cable is isolated
from the mains electricity supply!
en
Do not use a steam cleaner.
The appliance is only to be descaled by a
suitably qualified specialist.
Place hole 3 in the mounting template over the cold-water
inlet.
Select the most suitable hole through which the connect-
ing cable is be fed. The connecting cable must pass through
one of the six holes marked 14... Terminal BZ 45Z20 can
be used if the cable is fed into the continuous-flow heater
through one of the bottom holes marked 14a.
Mark the point 12 at which the mounting bolt is to be
inserted.
Fitting the mounting bolt and attaching the pipe
connecting pieces (Fig. B)
Open up the heater (Fig. C)
Punching out the holes at the rear of the heater for the
mounting bolt and the connecting cable
Important: When mounting the appliance, only the holes
actually required should be punched out. Any other holes
that are not going to be used must be sealed watertight.
Inserting the connecting cable (Fig. D)
Push the grommet 11 over the end of the connecting cable.
Note: Do not use the grommet for a cable with a cross-sec-
tion of 16 mm
. The appliance must then be installed flush
2
with the wall.
Attention: Without a grommet, the DH12103 is splashproof
only (IP 24).
Place the heater over the connecting cable.
Press the grommet into the hole in the rear wall of the
heater through which the cable should be fed. Ensure that
the edges of the grommet are flush with the hole all the
way round.
Fit the heater onto the threaded bushing 8 and secure it
in place with the nut 9.

Water connection
Using the locking screw 15, the water connection can be
aligned by ± 10 mm vertically.
Adapt the bend in the "hot" pipe so that it lines up with
the hot-water outlet. In doing so, make sure that the
"cold" elbow connection is not bent.
Attention: Ensure that a distance of at least 6 mm is main-
tained to live parts of the heater.
Connect the water outlet and inlet and tighten the secur-
ing nut on the mounting bolt.
Checking for leaks and flushing the heater:
Turn on the hot-water tap.
Check that all pipe joints are properly sealed.
