2 Safety instructions
Heating cables must always be installed according to
local building regulations and wiring rules as well as the
guidelines in this installation manual.
• De-energize all power circuits and do not connect the
plug to an outlet until installation is completed.
• Residual current device (RCD) protection is required.
RCD trip rating is max. 30 mA.
• Maximum fuse size is 10 A.
• In case of plug cutting the screen from each heating
cable must be connected to earthing terminal or
plug must be connected to outlet, securing a reliable
grounding of the screen in accordance with local
electricity regulations.
• In case of plug cutting heating cables must be
connected via a switch providing all pole disconnection.
• The heating cable must be equipped with a correctly sized
fuse or circuit breaker according to local regulations.
• Never exceed the maximum heat density (W/m or W/m²)
for the actual application. Refer to Application Guide.
• Heating cable must be used together with an
appropriate thermostat to secure against overheating
and reduce energy consumption.
• The cold lead is not allowed to be replaced by the user. If
cold lead is damaged, it must be replaced by service agent
or similarly qualified persons in order to avoid a hazard.
• This appliance can be used by children aged from 8 years
and above and persons with reduced physical, sensory or
mental capabilities or lack of experience and knowledge
if they have been given supervision or instruction
concerning use of the appliance in a safe way and
understand the hazards involved. Children shall not play
with the appliance. Cleaning and user maintenance shall
not be made by children without supervision.
CAUTION: If the cable is installed inside a drinking water
pipe, it is a precondition for the certification for in drinking
water application, to secure that the water does not reach
a temperature of 23 °C or above.It is a must to secure the
installation by a thermostat with a set-point of +5 °C.
The presence of a heating cable must
• be made evident by affixing caution signs in the fuse
box and in the distribution board or markings at the
power connection fittings and/or frequently along the
circuit line where clearly visible (tracing).
• be stated in any electrical documentation following the
installation.
3 Installation guidelines
• It is not recommended to install heating cables at
temperatures below -5°C.
• Heating cable bending diameter must be minimum
50 mm (to the inside of the cable).
• Do not bend and pull connections.
• Ensure that the cable is sufficiently fixed and mounted
according to the installation guide.
• The heating cables must be temperature controlled.
See safety instructions.
• Ensure controllers and sensors are connected
according to the applicable installation guide and/or
application guide.
• Measure, verify and record insulation resistance during
installation.
• Persons involved in the installation and testing of electrical
trace heating systems shall be suitably trained in all special
techniques required. Installations are intended to be
carried out under the supervision of a qualified person.
4 Application/Product overview
Pipe frost protection Tank frost protection
ECpipeheat 10 V3  
ECpipeheat 10 V3 is designed for preventing frozen water
pipes. ECpipeheat 10 V3 can be used on the outside of the
water pipe and will heat through the pipe and prevent it
from freezing. ECpipeheat 10 V3 can also be installed inside
water pipe, by using the dedicated fitting. It is certified
to be suitable for drinking and common water pipes and
is designed to be installed on pipe in all countries and
inside pipe in certified countries (DK, FI, SE, NO, RU), on the
condition that water temperature is always kept below 23 °C.

Specific heating cable length can be chosen from product range and used for different suitable projects. For more details
contact your local Danfoss sales company.
Note: In case of cold lead extension it is the full responsibility of the installer/designer to use proper cold lead
dimensioned for the purpose and assembly sets that establish sufficient mechanical strength, flammability resistance
and water proofing - and to design the heating unit with correct output for the specific application to avoid
overheating of the cable or building materials.
Regarding other types of applications please contact your local Danfoss sales company.

5 Thermostats/controllers
Pipe frost protection Tank frost protection
ECtemp 330  
ECtemp 610 
The ECtemp thermostat/controller must be commissioned as prescribed in the installation instruction for the actual
controller and adjusted where local conditions vary in relation to factory settings. Before every heating season or at least
once per year, check for faults in the switchboard, thermostat and sensors.
Each heating cable screen must be earthed in accordance with local electric regulations and connected to a residual
current device (RCD).
The heating cables must be temperature controlled and not operate at ambient temperature higher than 5 °C.
More information about thermostats and controllers can be found at www.danfoss.com.
Sensors:
• Sensors can be live (230 V) components and must be treated according to specific Installation Guide and local standards.
• Sensors can be extended using cable with the same cable construction and cross sections (up to 50 m).
• See section 7 for specific installations.

Fig. 3
1. Fit a T-shaped pipe of a generous size over the
pipe (3/4" and 1").
2. Fit the clean wadding (without side thread or
sharp edges) inside the T-shaped pipe with small
hole in the center.
3. Keep the cable clean and push the cable through
the wadding to facilitate the installation.
The connection between heating cable and
connecting cable must be outside the wadding.
Mount the wadding in the following sequence:
• use only clean tools before installation
as heating cable could be in contact with
drinking water;
• first you put the nut on facing the connection;
• mount the washer on the cable;
• mount the threaded part with the threaded
part facing the end of the cable;
• insert almost whole length of the cable inside
of the pipe, leave approx. 0,5 m of cable to
install rubber seal afterwards;
• the heating cable must extended straight
through the T-shaped pipe;
• install rubber seal on the cable. The conic
rubber seal has slice for heating cable.
4. Turn the nut until it fits tightly (max. torque for
pipe fitting is 30 N·m).
5. Insulate the pipe with at least 30 mm insulation or
thicker if required based on heat loss calculation.

1. Check the pipe system to be heated
and make sure that the pipes are dry,
smooth and tight. Check and prepare
the switch board.
2. Draw a plan positioning cable(s),
sensors and thermostat, cable
connections, cold tail, connection
box, cable paths and switch board.
3. Check the insulation resistance of
the heating cables. The measured
value shall be no less than 50 MΩ.
4. Straight lines and sensor must
be fitted as shown at Fig.2. Twisted
lines are attached as shown for every
approx.1 m pipe with aluminum tape.
5. Apply aluminum tape below
(mandatory for plastic pipes) and on
top on the whole length of the cable.
Make sure that the cables do not cross
sharp edges.
6. For in pipe installation use 3/4" + 1"
Pipe fitting to fit cable inside of pipe.
Max. water pressure – 10 Bar at max.
water temperature 23 °C. Max. torque
for pipe fitting is 30 N·m.
7. Attach and cover the sensor on
top of the pipe with aluminum tape.
Extend cold tails/leads and keep
connections dry. Mount connection
box on the pipe or close to it and
install the thermostat on the pipe or
near it (depends on thermostat).
8. Re-check the insulation resistance.
Connect cables to connection boxes
and to the switch board.
9. After insulation, place safety
marking tape on the insulation jacket
or pipe trenches for every 5 m. In
subsurface installations, a cover
ribbon with a warning sign must be
laid 10 cm above the cables.
