Caution!
Is it important to read the instructions carefully before installing the Danfoss GX
Snow Melting System.
For outdoor installation only;
l
Never cut the black heating cable;
l
Extreme care must be used to ensure the GX cables are not damaged when using sharp
l
tools, wheelbarrows, heavy machinery and paving equipment, shovels, rakes, or other
implements. Avoid walking on the cables or mats during installation;
It is not recommended to install the Danfoss GX heating mats with a controller that
l
does not contain an integrated temperature limiter;
The GX mat or GX cable must be embedded in mortar or mortar mixture, concrete, sand
l
or similar material;
The power lead/heating cable connection and at least 1' (30 cm) of the power lead
l
must be embedded in the paved surface;
l
Remaining power lead should be run through the conduit
The power lead may be extended if required;
l
Do not install the Danfoss GX cables in such a manner that two black heating
l
cables touch, cross or overlap;
Remember to always measure, verify and record the actual resistance throughout the
installation process:
1. Out of the box
2. After installation
3. Before pouring the sand/concrete/asphalt
4. After surface material application
Record these values in the table on page 20 and on the warranty card, failure to do so
will void the warranty;
Measure the resistance between two live conductors as well as the resistance between
l
each conductor and the ground wire.
l
Danfoss recommends using a megaohmmeter to test the insulation resistance.
Remember to check that the supply voltage matches the voltage required for your
l
particular Danfoss GX product;
Remember to place the labels as instructed in this manual;
l
l
Metal structures or materials used for the support of or on which the Danfoss GX is
installed must be grounded in accordance with CSA Standard C22.1, Section 10 and the
