CONTENTS PAGE 1.0 PRODUCT SPECIFICATIONS 1.0 Product Specifications .............................................................................. 1 WarmlyYours Heating Cable is designed for new concrete slab floors. It is well suited for large areas like basements, garages and additions. 2.0 Selection of the Heating System................................................................. 2 The Heating Cable is comprised of a dual, multistrand heating element with a primary insulation of Fluoropolymer.
10 2.0 SELECTION OF THE HEATING SYSTEM over cable. Duct tape the ends of shovels. Do NOT saw expansion joints, without having lines marked off clearly with spray paint, where installer has verified that Heating Cables will not be cut. Do NOT damage Cables with heavy equipment, machinery or vehicles. Selection of your Heating System will depend on the application. The following can be taken as a general guide: 6.
Cold Lead 4.0 INSTALLATION FOR INDOOR SLAB HEATING WARNING 4.1 TEMPERATURE CONTROLLER & SENSOR In case the GFCI in our thermostat trips during normal operation, and cannot be reset, there is likely a fault in the Cable. No attempt should be made to re-energize the system. The GFCI must not be bypassed under any circumstances. Consult a qualified electrician. We recommend a standard Programmable Thermostat with a temperature sensor specially designed for control of the Heating System.
4.3 PRE-INSTALLATION PREPARATIONS 1. Review the custom installation plan for the area requiring the Heating System and verify dimensions listed against your actual field dimensions to ensure they match. 2. Confirm the location of the power supply box/Thermostat and sensor against the plan. 120 the VACprocured SUPPLY 3. Select Heating Cable(s) and ensure that Cable is correct according to 8. H eating Cable should be laid so that the Cables are equally spaced.
4a. For Two-Pour Installations: The concrete installer pours the first 2” to 3” (51mm to 76mm) of concrete. While this first pour is still wet, rebar or wire-mesh should be placed on top of the first pour. The cables should be attached to the rebar / mesh with plastic zip ties, using 3” to 5” (76mm to 127mm) spacing for freeform type cable. At this time, the electrician must route the cold lead(s) thru rigid metal conduit(s) to get back to an accessible junction box(es).
4.7 INSTALLATION OF SLAB HEATING MAT Use scissors to cut the Mat. NEVER cut the Heating Cable For 180 Degree Turn Turn the Mat Maintain 3” gap between all cable and mat passes Flip / Turn the Mat suitably 3” 180˚ For 90 Degree Turn Maintain 3” gap between all cable and mat passes For other shapes, detach Cable from Mat to required length and lay only Cable. Means of attachment may vary project to project.
5.0 TESTING THE MATS AND CABLE In case of defective material, WarmlyYours obligation will be limited to the repair or supply of new material, free of charge to the customer. 5.1 TEST ONE: TOTAL CABLE RESISTANCE (MULTI-METER REQUIRED) The warranty does not cover installations made by unqualified persons or faults caused by incorrect design by others / misuse / damage caused by others / damage in transit / incorrect installation and any other subsequent damage that may occur.

Slab Heat Troubleshooting Guide SYSTEM NOT WARMING NO POWER TO HEATING PRODUCT 1. Do an amp draw test on the cables to verify proper operation. 1. T est ohms of heating cables/rolls 2. Thermostat/control set at too low of a temperature. Adjust to higher temperature. Because of the nature of slab heat, any changes in slab temperature will take time to accomplish. Slab heat has a much slower reaction time that floor surface heating. a. V erify proper ohms per roll/cable b. Verify no shorts c.
