King Electric TCM - Manual (Page 2)

It is recommended to install the TC heating cables/mat with a controller that contains an integrated temperature limiter.
Remember to check that the supply voltage matches the voltage required for your particular TC product.
Extreme care must be used to ensure the TC cables are not damaged when using sharp tools, wheelbarrows, heavy machinery, shovels, rakes,
or other implements. Avoid walking on the cables or mats during installation.
READ THESE INSTRUCTIONS BEFORE BEGINNING THE CONSTRUCTION OF THE FOUNDATION
Never cut the heating cable.
Do not install the TC cables in such a manner that two heating cables touch, cross or overlap.
Measure, verify and record the actual resistance throughout the installation process:
1. Out of the box
2. During installation
3. After laying the sand bed (for sand bed installation)
4. After the concrete slab is poured (but not set)
5. After connecting thermostat and/or contactors
Record these values in the TC Cable / TCM Mat Testing Log . Failure to do so will void the warranty.
The TC thermal storage heating system is most effective in single story buildings, with tiled or stone or concrete floors. If carpet, wood or other
flooring materials are to be used, please consult with King.
The TC mat or TC cable must be embedded in mortar or mortar mixture, concrete, sand or similar material. Ensure no air pockets exist in the
concrete or sand. This can damage to the cable.
The perimeter of the heated area should be insulated to 4 feet below grade with a minimum of 2 inches of rigid, closed cell foam insulation
(styrofoam) or equivalent suitable for in-ground installation. Foamed urethane or polystyrene are not acceptable moisture reduced its insulation
properties.
Ensure that all sharp stones and debris are removed from the area where the heating cables are going to be installed.
Make sure the cable is not subjected to excessive tension or strain, especially at the heating cable to power lead slice. It should not cross an
expansion joint when installed in concrete. For two or more slabs, use separate cables in each slab.
At low temperatures, the heating cable stiffens and may be difficult to work with. To overcome this, connect the cable to the mains for a brief
period of time. Ensure the cable is fully rolled out when this is done.
A minimum of 12 inches (30 cm) should exist between the cables and the perimeter of the foundation, and obstructions such as drains,
conduits, and structural members.
There should be a minimum of 2 inches (5 cm) of concrete or sand above and below the heating cables.
Allow the concrete to set for at least 30 days before the heating cables are turned on.
There should be no moving groundwater in the building area. Natural moisture in the soil is acceptable. If in doubt, contact King.
Please consult the King for any other questions, concerns or advice.
