 Connection of the heating cable must be carried out by an authorized electrician.
 Note the maximum output allowed for your installation. Do not exceed it. Contact
your local Danfoss GX dealer for questions/concerns.
 Make sure the cable is not subjected to excess tension or strain. It should not cross an
expansion joint.
 The heating cable braid must be grounded in accordance with local electrical codes.
 Make sure when the cable is laid, that it is not pushed into the insulating material.
 Ensure no air pockets exist in the surface material as this can result in damage to the
cable and limit the heat transfer.
 An upstream disconnect must be installed to ensure a means of de-energizing the
cable or mat.
 At low temperatures, the heating cable stiffens and may be difficult to work with.
To overcome this, connect the cable to the mains for a brief period of time. Ensure the
cable is fully rolled out when this is done.
Special care must be taken not to damage the heating cables when they are installed
under bricks or tiles.
The area must be completely level and free of stones or other sharp objects.
The heating cable must be installed close to the bricks or tiles, typically in a layer of sand
(at least 1" (2.5 cm) under the brick).
