Installation - for contractors

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 sur-

face that you want to heat.

» If you are using thermal insulation with a sheet metal

jacket, use an insulation grommet to protect the rib-

bon heater from mechanical damage.

Material damage

Make certain that the ribbon heater's supply con-

ductors 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 pre-

vent 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.

D0000032840

Material damage

To prevent short circuiting, trim one of the two sup-

ply conductors to approx. 10 mm.

applying adhesive.

» 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.

» 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 con-

ductor 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
