We recommend that you always use a controller for controlling the self-limiting heating cables to avoid
waste of energy.
Inform the end user to check for and remove sharp
edges, leaves, and dirt from the heated roof and
gutter systems every autumn.

Finalizing the Installation
Connecting cables
• Connect all cold leads and the sensor to the
connection box.
• See the installation manual for the thermo-
stat.
Final check and documentation
• Make sure that the heat distributor (e.g.
roof, pipe) can withstand the heat from the
element. This is particularly important if the
element is connected to a thermostat that
does not allow configuration of maximum
temperature - see section 4.4.
• Document the following using text, drawings,
or photos:
• cable type, spacing, depth, layout,
circuit ID, sensors.
• location of connections between cold
lead and heating element.
• location of end caps (twin conductors
only).
• location of expansion joints, if any.
• Re-check and compare the insulation resis-
tance.
