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.
