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.

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.

Application/Product overview

DEVIpipeheat™ 10 V3 is designed for preventing frozen water pipes. DEVIpipeheat™ 10 V3 can be used on the outside of the water pipe and will heat through the pipe and prevent it from freezing. DEVIpipeheat™ 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, EE, FI, LT, LV, 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 DEVI 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 DEVI sales company. More information about applications (maximum linear output, specific output, heating circuit length, voltage etc.) can be found at www.devi.com

Thermostats/controllers

The DEVIreg™ 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.devi.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.

Typical installations

Typical pipe tracing installation

On water pipe installation

1. Heating cable

2. Aluminum tape

3. Wire sensor

4. Insulation

5. Warning label/tap

6. Apply aluminum tape below (mandatory for plastic pipes) and on top on the whole length of the cable.

7. Insulate the pipe with at least 30 mm insula- tion or thicker if required based on heat loss calculation.

In water pipe installation

1. – Heating cable;

2. Aluminum tape;

3. Wire sensor;

4. Insulation;

5. Warning label/tape;

6. 3/4″ + 1″ Pipe fitting

7. Fit a T-shaped pipe of a generous size over the pipe
   (3/4″ and 1″).

8. Fit the clean wadding (without side thread or sharp
   edges) inside the T-shaped pipe with small hole in
   the center.

9. Keep the cable clean and push the cable through the wadding to facilitate the installation. The con- nection 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.

10. Turn the nut until it fits tightly (max. torque for pipe fitting is 30 N·m).

11. 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 switchboard.
2. Draw a plan positioning cable(s), sensors and thermostat, cable connections, cold tail, connection box, cable paths and switchboard.
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 for DEVIpipeheat™ 10 V3 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 the connection box on the pipe or close to it and install the thermostat on the pipe or near it (depending on the thermostat).
8. Re-check the insulation resistance. Connect cables to connection boxes and to the switchboard.
9. After insulation, place safety marking tape on the insulation jacket or pipe trenches every 5 m. In subsurface installations, a cover ribbon with a warning sign must be laid 10 cm above the cables.
