cut or shorten the heating wire at any time.
DON’T

DON’T
bend the heating cable under a 25mm radius.
The heating must be separated from other heat sources such as luminaires and chimneys.
WARNING
During the course of the installation care must be taken to ensure that no damage is caused by, for
example, falling objects, sharp objects, walking on the heating element. Once the heating wire has been
installed avoid all traffic over the wire until the floor has been tiled and the adhesive has set. Do not install
the heating wire until the floor is ready to be tiled. If the floor is not being tiled immediately, all heating
wires must be protected with two layers of cardboard or hardboard to prevent damage. Immediately prior
to tiling, test the heating wires as specified on page 14 to check it has not been damaged. If you are in
any doubt call the Warmup
®
Undertile Heating helpline on
