IMPORTANT:The electrical resistance of the cable must be checked before you begin and monitored
throughout the installation process to ensure there has been no damage causing shorts or breaks.
WarmlyYours recommends at least three readings be taken:
1. Before starting installation
2. After securing the cable in place on the suboor
3. After installing the ooring surface on top of the cable
