Begin by fastening the heating mat to the mesh reinforcement using tie-wraps or cable strapping.
Do not fix the heating cable of the mat in such a way that it is compressed or strained - it must be
able to move. Unroll the mat up to the point at which it is to be flipped and turned. Use the figure on
page 5 to alter the mat.
Cut the tape using scissors and rotate the mat so that it can be unrolled to cover the area next to the
already unrolled mat. Do not cut the cable! The cable can be carefully detached from the tape
and then placed as free cable. This feature can be very useful for curves and around drains or other
obstructions.

The GX cable must be laid out with even spacing over the entire area to be heated. To ensure an
accurate and easy method of installing the GX cable it is recommended to use Danfoss cable
strapping. Attach the cable strapping to the rebar or other supporting structure using tie-wraps.
The strapping should be laid perpendicular to the direction the cable will be unrolled. Space the
strapping 3' (75cm) apart. Secure the heating cable to the cable strapping at the correct center-to-
center distance. Do not secure the cable too tightly as this may damage the cable. If not using the
cable strapping, affix the heating cable to the rebar or wire mesh using tie wraps.

The C-C distance is the distance between the GX cables (GX mats have a preset C-C distance).
Standard spacing for 50W/sq.ft. (540W/m ) is 3" (7.5 cm). In a typical application the C-C distance
should not exceed 4" and be less than 3" if the cables are installed as part of a total heating system.
If the C-C distance is higher, cold spots may form on the surface and incomplete melting may occur.
