– Priority circuit
in combination with
other electrical units, such as electric stor-
age heaters, the load-shedding relay is to be
used:
a Load-shedding relay (see "2.15 Special
Accessories").
b Control line to the switching contactor of
the second unit (e.g. electric storage
heater).
c Control contact, open when the DEL
electronic is switched on.
Load-shedding takes place when the DEL
electronic unit is in operation.
The load-shedding relay may only be
connected to the middle phase of the
unit terminal strip.
• Connection in the lower unit area
In the delivery state, the unit is prepared for
the electrical connection to be in the lower
part of the unit.
– Set the unit up as shown in the illustration.
– To provide a seal against water penetration,
the cable grommet (33) provided must be
used.
– Connect the connection lead to the termi-
nal block.
• Connection in the upper part of the unit
Preparing the unit for electrical connection at
the top:
– Knock out the infeed aperture marked out
in the rear wall (a) of the unit.
– Shorten the cable grommet (b) for the seal,
wet with a rinsing agent on the inside to
provide a better fit (sliding capacity), and
install in the rear wall (c).
– Release the plastic profile strip (d).
– Release the terminal block (e).
– Fit the terminal block in the upper part of
the unit (f). Care must be taken to ensure
that the switch lead wires do not project
over the rear wall of the unit.
– Fit the plastic profile strip (g).
Carrying out the electrical connection
To provide protection against water pen-
etration, the cable grommet provided (c)
and the plastic profile strip (g) must be fitted
and the dimensions properly respected.
– Connect the connection lead to the termi-
nal strip.
2.12 Completing installation O
1. Open the three-way isolating valve (a)
2. Fix the lower part of the rear wall (b)
3. Fit the lower securing screw (c).
4. For surface screw connection only
Knock out the passage apertures (a) in the
cover in an appropriately clean manner, or
use a file. The guide pieces (b) provided
with the unit must be engaged in the
apertures.
5. For under-sink installation only
Shift the snap nut (a) from the bottom to
the top. Remove the control panel (b)
from the cover, unscrewing the screws in
the cover for this purpose. Rotate the
cover, lay in the control panel and secure
with the screws.
6. If required, activate the temperature miter
G
(see "2.9 Temperature Limitation").

adding cold water via a bypass line, that the
output temperature of 60 °C will not be
exceeded.
Service monitor
Order No. 16 77 41
Diagnostic unit for fault recognition in the
DEL electronic .
Universal installation frame
Order No. 07 37 90
With rear wall and electrical wiring.
This module creates a hollow space be-
tween the rear wall of the unit and the
installation wall. This allows for a concealed
electrical connection to be fitted at any
desired point behind the unit. The depth of
the unit is increased by 30 mm. The protec-
tion mode will be changed by the addition
of the module, to IP 24 (spray water pro-
tected).
