drinking water cable
devi ex

DTIV is a twin conductor
heating cable with polyethylene outer
sheath, designed for installation in
drinking water pipes.
devi ex
™
DTIV can be installed in
existing as well as new pipes.
When devi ex
™
DTIV is installed
in pipes, a reliable and troublefree
supply of water is ensured at all times
without freezing over.

Generel installation instructions
The following instructions must be
observed when installing devi ex
™
DTIV heating cables:
The heating cable should be
properly connected to the main
electrical source.
Connection of the heating cable
must be made by an authorized
electrician.
The maximum effect for the
different installations and operating
effects must be observed.
The heating cable must not be
pulled through valves and must
be protected against excess strain
and tension.
The heating cable’s bending
diameter must not be less than 6 x
the cables own diameter.
The heating cable’s screen must
be earthed in accordance with the
local electricity laws.
The heating cable must not be cut
or exposed to strain in the areas
of the cold cable coupling or end
coupling.

The whole heating cable, except
the connection box and cold cable
must be placed inside the water
pipe.
When turning on the heating cable
ensure that the pipe is containing
water.
The heating cable’s resistance
value should be measured after
the installation. The heating cable’s
resistance value should be as
stated on the coupling label: -5
- +10%.
Heating cables installed in water
pipes must be connected via a
RCD.
It must be possible to turn the
heating cable off. We recommend
a devireg
™
thermostat (see later).
A piece of non conductive tape
must be placed between the
sensor and the pipe
The cable must be installed accor-
ding to local installation regulation.

The optimal control of devi ex
™
heating cables is achieved by using
devireg
™
electronic thermostat.
devireg
™
thermostats give a quick
and effective regulation and take
into consideration both comfort and
economy.
There are a wide variety of devireg
™
thermostats which can be chosen
according to the demands of the indi-
vidual installation.
The sensor cable can be exten-
ded with up to 50 m with a 0.75
mm².cable.
