General Installation instructions
The following guidelines must be
observed when installing the heating
cable:
The heating cable must be
1.
installed with a xed connection
(not a plug socket).
An authorized electrician must con-
2.
nect the heating cable to the thermostat.
The speci ed maximum output for
3.
various installation and operating
conditions must be respected.
The heating cable must be
4.
protected against mechanical
stress at all times and must never
be stretched.
Clean the surface and remove any
5.
sharp objects.
The ex diameter of the cable
6.
must not be less than 6 x the cable
diameter.
Ensure that the cable do not touch
7.
or cross one another.
Do not lay the connection box and
8.
the end of the heating cable in wet
areas such as showers or under bathtubs, etc.
9.
Do not lay the heating cable under
built-in baths, cupboards, walls, etc.
10.
Connect the earth wire of the
heating cable in accordance with
regulations.
11.
Do not shorten the heating cable
as this will increase the output per
metre cable.
12.
Check the insulation resistance and
the resistance of the heating cable
once it has been installed, both
before and after the concrete is
poured. The resistance of the cable
must be as speci ed on the label: -5
– +10%.
13.
It should still be possible to move
the heating cable after attaching any
type of xing strips.
14.
The heating cable must be equipped
with a circuit breaker. In addition, we
recommend the use of a Devireg™
thermostat.
15.
The cable is marked every
one-meter but please note that
smaller deviations compared to the
cable’s actual length might occur.
The meter marking is only meant as
a help when laying out the cable.
Fig. 1
The heating cable should not be installed at temperatures below –7°C. If you have
to lay the cable at low temperatures, try connecting the cable for a short while as this
will make it easier to install. Please note that the cable must, in this case, be rolled out
to keep the cable temperature from getting too high.
Installing the cable in thin oor constructions
Thin oor constructions are particularly
relevant in connection with house renovations and in places where construction
height and drying times, etc. must be
taken into account.
Please note that, in case of thin oor
constructions, it is important to choose
the right cable for the oor in question.
The C-C distance must not exceed 12 cm.
DEVI o ers the complete heating solution.

with ceramic tiles
Fig. 2
Any instructions relating to the concrete
mixture must be closely observed, and
the supplier of the oor covering must
be informed that under oor heating has
been installed in order to ensure that the
most suitable product is chosen.
When installing a wood/laminate oor,
we recommend the use of a combination thermostat that limits the oor
temperature, such as the Devireg™ 132,
522, 535.

Installing the heating cable in cement oors
Lay the heating cable evenly across
the oor, avoiding any obstacles. The
surface must be clean and free from
sharp objects. For quick and simple
installation, we recommend the use of
Devifast
™
xing strips.
A Devireg™ thermostat should be used
at all times. If a oor sensor is used, it
should be installed in a pipe. The pipe
should be placed in the concrete between the cable loops and the end of the
pipe must be sealed. We recommend
that you draw a simple sketch showing
the cable’s position.
A decision must be made as to
whether or not the oor should be
insulated. This depends on the existing
oor construction, the location of the
oor, the construction height, etc. The
under oor heating must not be used
until the concrete has hardened, i.e. after
approximately 6–8 weeks or as speci ed.
