Asphalt Installation

When installing heating cables the following should be observed:
Begin installation as close as possible to electrical supply source. The heating cable
must not be cut or shortened or exposed to strain in the areas of the cold tail/heating
cable coupling.
Install cables in a direction perpendicular to the direction that the paving rollers will
pass to prevent straining or damaging the cable.
Insulation can be installed to improve efficiency of the heating system.
When placing the sensors please see page 7.
Special care should be taken not to damage the heating cables with tools and
machinery during the installation and application of the surface material.
Ensure that all sharp stones and debris are removed from the area where the heating
cables are going to be installed.
Should the cable become damaged during the installation process it is helpful to know
the location of the cold tail/heating cable connection. Take a picture or sketch to show
where the connection/end cap is in case a fault needs to be found.
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 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
thecable is fully rolled out when this is done.
