3. Appliance description

The self-limiting SLH ribbon heater is an energy efficient way of keeping pipework free from frost, particularly outdoors. It consists of 2 supply conductors routed in parallel, that are separated from each other by a special semiconductor matrix.

At low temperatures the electrical resistance of the ribbon heater drops, causing the output to increase. At high temperatures the resistance rises and the output drops.

The ribbon heater can be trimmed individually. The end of the ribbon heater can be appropriately resealed with the terminators provided.

Note

The use of higher ranking control units is advisable as these can save energy, keep process temperatures constant and protect the ribbon heaters.

» If in doubt, consult our service department.

4. Installation

4.1 Protective measures

WARNING Electrocution

We strongly recommend the use of an RCD (30 mA).

» If you are using the ribbon heater on metal, make sure you protect the ribbon heater against indirect contact to DIN VDE 100, part 410 prior to commissioning.

» Protect the ribbon heater against mechanical and chemical damage.

4.2 Preparations

» Before fitting the cable, ensure that the area around the pipe is freely accessible.

» If you want to fit the ribbon heater to a plastic pipe, first wrap the plastic pipe in aluminium foil to ensure optimal heat distribution.

4.3 Installing the heating circuit

Material damage

Keep the ribbon heater away from any sharp edges or easily flammable materials to prevent damage to the ribbon heater and surrounding areas.

Note

There is no danger of overheating if ribbon heaters overlap or touch.

» Remove sharp burrs or any other roughness from the surface you will be heating. » Clean and degrease the surface you will be heating.

Power supply

WARNING Electrocution

Carry out all electrical connection and installation work in accordance with relevant regulations.

Material damage

Observe the type plate. The specified voltage must match the mains voltage.

» To prevent condensate from the pipe entering the standard socket, form a "drip loop" with the power cable.

Positioning the thermostat

The thermostat measures the temperature of the pipe and switches the ribbon heater on and off as required.

Pure electrical circuit lines without any symbols

» Secure the thermostat with a close fit against the pipe at the coldest end of the pipe. Use suitable fixing materials for this purpose, such as fabric tape, aluminium adhesive tape or temperature-resistant cable ties.

Installing the ribbon heater

Note

Secure the ribbon heater to the underside of the pipe.

» Hold the ribbon heater against the pipe parallel to the pipe run, and secure it with aluminium adhesive tape or temperature-resistant cable ties every 20 - 30 cm.
» Cover the ribbon heater with aluminium foil along its entire length to prevent thermal insulation material penetrating between the ribbon heater and the surface that you want to heat.
» If you are using thermal insulation with a sheet metal jacket, use an insulation grommet to protect the ribbon heater from mechanical damage.

Material damage

Make certain that the ribbon heater's supply conductors do not touch each other as this will cause a short circuit.

» Ensure the ribbon heater is appropriately supported in the area next to the electrical connection to prevent any pulling, pushing or twisting forces being applied to the connection.

4.4 Trimming the ribbon heater and terminator

Note

Use a tool that is appropriate for the cross-section of the cable.

» Trim the ribbon heater to the required length.

D0000032838

» Strip the end of the ribbon heater to a length of 15 mm.
» Pull back the protective braiding.

» Apply silicone adhesive to the supply conductors in a wave pattern.
» Check the end cap for integrity.

D0000032842

» Drip silicone adhesive into the end cap until the cap is around 40 % full of adhesive.

D0000032848

» Slide the end cap fully onto the end of the ribbon heater.
» Carry out a visual inspection to check that the end cap is correctly positioned on the end of the ribbon heater and is not loose.

4.5 Checks

Once you have finished with the heating circuit, carry out the following checks before fitting the thermal insulation:

» Visually inspect the ribbon heater for any mechanical damage.
» Repair any damage. If the heating circuit is only short, replace the ribbon heater. If the heating circuit is long, cut out the damaged section and use a new section of ribbon.

Note

The insulation resistance must not be below 20 MOhm.

» Measure and log the insulation resistance of the heating circuit between each individual supply conductor and the protective braiding. The test voltage is 1000 V.
» Check the function of the heating circuit.
» Repeat the checks once the thermal insulation has been fitted.
» Identify electrically heated systems with warning labels (e.g. SLHZ stickers) positioned every 5 m.

5. Operation

Note

» Observe local safety regulations.
» Ensure compliance with the permissible operating conditions outlined in the specification table.

6. Maintenance

Self-limiting ribbon heaters are generally maintenance-free. We recommend you arrange for a contractor to carry out a visual inspection and check the insulation resistance on a regular basis.

» When carrying out repairs to heated system parts, protect the ribbon heater from damage.

WARNING Electrocution

Controllers, terminal boxes and female connections may only be opened while the system is isolated from the power supply.

» Recheck the heating circuit once the repair work is complete.
» Damaged heating circuits must be taken out of use.
» Arrange for a contractor to check the thermostats and controls on an annual basis.
