II. 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 existing 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)
CAUTION:
Important!
Make sure that the connecting cable is isolated from the mains electricity
supply!
• Place hole 3 in the mounting template over the cold-water inlet.
• Select the most suitable hole through which the connecting cable is
be fed. The connecting cable must pass through one of the six holes
marked 14.. . Terminal BZ45Z20M can be used if the cable is fed into the
continuous-flow heater through one of the bottom holes marked 14a .

Attention:
Without a grommet, the TR1000 12 B 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 .

III. 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.
CAUTION:
Attention:
Ensure that a distance of at least 6 mm is maintained to live parts
of the heater.
• Connect the water outlet and inlet and tighten the securing 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.
IV. Electrical connection
• As a matter of principle, the water connections must be completed
first of all before the heater is connected to the electricity supply.
The appliance should be wired up according to the circuit diagram
on the inside of the cover.
