Installation Manual

The ElectroMelt EM2-XR heating cable is a high-powered, self-regulating heat-
ing cable for concrete snow-melting and anti-icing applications. The uniquely
blended polymer core of the heating cable adjusts its power output at every
point along its length to eliminate hot spots and burnouts that can be experi-
enced with constant-wattage heating cables. A heavy-duty, modified polyolefin
outer jacket resists abrasion, puncture, and damage caused by rough handlling.
