Page 3: Step ® Snowmelt System
® STEP Snowmelt heating elements are powered by a 24V low voltage AC Power Supply or DC Controller. The heating elements, which can be cut to size on site are available in different widths and protected by a chemically, inherently inert and dielectric insulation. -

Polyethylene Film Slots Increase Flexibility The STEP ® Snowmelt heating elements MEP-30-70W and MEP-23-80W are designed to prevent ice and snow on walkways and driveways. The element is constructed of two parallel bus braids embedded in semi-conductive PTC polymer. A polymeric dielectric liner is applied at the time of manufacturing so that the liner is thermally fused to the heating element. -

Page 10: Installation
When deciding on a snowmelt system it is essential to decide on the purpose of the system and how effective the system should be. Should the ground be completely dry or is it acceptable with some snow slush on the ground shortly after a snowfall. -

Page 12: Make The Connections
Strip the wire end, and join the ® wire with the bus braid in the STEP tinned copper crimp connector. Crimp the joint using the required crimp tool. Using components not recommended by the manufacturer will void the warranty. -
