B.
C. D.
1.7 Manufacturer Qualifications & Services: 1. 5 years of experience ( minimum ) with electric radiant snow melting systems. 2. Snow melting mats/cables, controls, sensors, relays, and related items shall be provided by one manufacturer. 3. Must provide 24/7 technical installation support, and free design assistance. Installer Qualifications: 1. Must have verifiable experience successfully completing projects of similar size, and /or has been trained or certified by a manufacturer’s representative. 2. A licensed electrician shall complete all electrical rough-­‐in, and electrical connections required to complete the system installation. Regulatory Requirements and Approvals -­‐ Electric Snow Melting Systems. Provide an electric snow melting system that complies with the following requirements: 1. Snow melting cables/mats for installation in concrete, asphalt, or under pavers shall be Listed to UL 1673, UL 515, ANSI/IEEE 515.1 and CAN/CSA -­‐C22.2 No. 130. Pre-­‐Installation Meetings: 1. Coordinate work with other trade representatives ( general, electrical, paving, and other trade contractors ) to verify areas of responsibility ( scope of work ). 2. Review project timeline and construction deadlines to ensure project will comply with all manufacturer’s installation instructions and warranty requirements. DELIVERY, STORAGE AND HANDLING A.
B.
Deliver materials in manufacturer’s original, unopened, undamaged containers with identification labels intact. Store materials protected from exposure to harmful site conditions, and in an area protected from vandalism and theft. PART 2 PRODUCTS 2.1 MANUFACTURER A.

Substitution requests must be approved 15 days prior to bid due date. Alternative equipment manufacturer must provide all relevant product data sheets, warranty, installation instructions, shop drawings, samples, and electrical schematics. Alternative equipment must meet specified material standards. 2.2 ELECTRIC RADIANT SNOW MELTING MAT/CABLE A.
The WarmlyYours Heating Cable consists of a two-­‐conductor stranded copper alloy resistance wire covered by primary fluoropolymer insulation. A braided metal sheath surrounds the primary insulation, and serves as a ground, before a second ( final ) layer of PVC, EPR, or Zero Halogen Polyolefin jacketing, which serves as the outer shell. The heating cable is taped in a serpentine pattern to a flexible polypropylene mesh at 3” on center spacing ( for mats only ). The 20 Ft cold lead return wire is factory installed ( spliced ) at one end of the mat/cable. All hot section must be green in color. All cold lead section must be black in color, and include a UL label for identification. B.
The WarmlyYours Snow Melting Mat/Cable shall be 120 VAC or 240 VAC, producing 45 watts per square foot ( min ) and be UL Listed. Multiple mat systems must be wired in parallel by the installer. Each mat/cable heater must have a minimum 10 yr manufacturers warranty. 2.3 CONTROLS, SENSORS & ACCESSORIES A.
B. C. SCP-­‐120 automatic snow melt control shall be 120 VAC, UL Listed, have multiple sensor capability, have remote control/monitoring option, and include a manual override cycle push button for easy activation. Control shall be able to control electrically held relay panels for additional load switching to accommodate for larger systems. AIR-­‐SS aerial mounted snow sensor shall detect snow and ice, utilizing a heated moisture sensing grid, and an ambient air temperature sensor. Sensor shall be of solid state design, combined with rugged housing and epoxy potting. Sensor is a NEC Class 2 low voltage device for simple installation up to 2,000 ft away from the SCP-­‐120 control panel. OT-­‐SENSOR slab mounted over-­‐temp sensor shall be provided with the SCP-­‐120. This sensor shall be inserted into ¾” rigid metal conduit ( capped off ), and positioned between two of the snow melting cables/mats. Sensor must be replaceable. Sensor shall not be installed in asphalt slabs, until after the slab has cooled lower than 120 degrees F. PART 3 EXECUTION 3.1 MANUFACTURER’S INSTRUCTIONS A.
Comply with manufacturer’s product data, including product technical bulletins, installation instructions and design drawings. 3.2 EXAMINATION & PREPARATION A.
Installer shall verify field measurements are as shown on Shop Drawings(s). B.
Any revisions needed to Shop Drawings, or product provided, must be corrected prior to proceeding with the installation. C.
Prepare your base, as per the standard guidelines set forth by the American Society of Concrete Contractors. Remove any rip-­‐rap, glass, or other sharp objects, that may damage the heating mat. D.
Installer shall verify that the required power, is available, in proper location, and ready for use. 3.3 INSTALLATION A.
Complete installation must conform to appropriate manufacturer’s installation instructions, National Electrical Code, and appropriate local codes. 3.4 FIELD QUALITY CONTROL A.
