Making The Worktop Recess; Gluing In The Hob - Bauknecht CTDI K 940C NE Instructions De Montage

2.7 Making the worktop recess

The cut-out is produced in two work steps.
1. Making the opening for the base trough.
2. Making the recess for the support of the glass ceramic
hob.
(For this recess at least one recessing machine with
guide strip is required.)
The outside dimension of the recess should always be
about 6 mm longer than the outside dimension of the glass
ceramic hob so that a seal can be provided (see: Gluing in
the hob).
Alternatively, instead of carrying out the second stage, the
support of the glass ceramic hob can be cut out completely
and then glued in again with the height adjusted.
It is also possible to install strips of wood or stone as well
as steel angles.
1. Make the opening for the hob.
2. Fix the strip of wood or stone or the supporting angle
onto the worktop.
Please note
In order to ensure that it is exactly fl ush with the stone
worktop, the recess may have to be modifi ed accordingly.

2.8 Gluing in the hob

Notes
• In order to avoid damage to the worktop and the hob,
it is necessary to glue the system worktop/hob with a
permanent seal so that it is water-proof.
• The parts to be glued together must be dry and free
from grease.
• To glue the hob, you require the water-proof wash
primer and the heat and moisture-resistant silicone
adhesive (150°C).
• It is absolutely necessary to observe the remarks con-
cerning these two products.
There you will also fi nd a calculation formula for the
hardening of the silicone adhesive. Do not operate the
cooking zone before the hardening process is over as
otherwise the silicone adhesive can be damaged.
Instructions for assembly
• Only glue the hob on its outer edges!
• Never place the hob with the glass ceramic surface un-
protected on the worktop or the fl oor. Dirt (metal chips,
small pieces of stone etc.) can cause scratches in the
surface of the glass ceramic hob. Please always place
it on cardboard or a wool rug.
Procedure
1. Glue the sealing tape
ting edge of the worktop so that no silicone adhesive
Important: Only use the sealing tape that is supplied
with the hob! Should you use any other sealing there
is no guarantee that the hob will not sink down after
installation.
2. Insert the hob without adhesive into the worktop
opening and check the height If necessary, place the
shims provided on the support edge for the hob at
equal distances to adjust the height.
3. Remove the hob again.
4. Use the wash primer to pre-treat the outer edges of
the hob and the side cut surfaces of the worktop where
they have been glued.
Apply a thick coat of the primer with a brush on highly
absorbent surfaces (e.g. chipboard). With less absor-
bent surfaces (e.g. marble or granite) it is suffi cient to
apply the primer with a felt cloth.
Important: After application, the primer must be left for
about 30 minutes.
5. Now insert the hob and align.
6. Finally, fi ll the gap between the hob and the worktop
with silicone adhesive
7. Smooth the joint with a spatula and water containing a
little washing-up liquid.
Attention: Use sealing tape
not get under the support surface. If this occurs it will not
be possible to remove the hob again at a later stage. No
liability will be assumed in the case of failure to observe
these instructions.
