1 - Heating cable; 2 - Aluminum tape; 3 - Wire sensor; 4 - Insulation; 5 - Warning label/tape
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 heat-
ing cables The measured value shall be no less
than 50 MΩ
4 Make connection and end terminations
using only authorized accessories
5 Straight lines and sensor must be fitted
as shown at Fig2 Twisted lines are attached
as shown for every approx1 m pipe with
aluminum tape
6 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
7 Attach and cover the sensor and the tip 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
