TapeMat ® Installation Manual Series D12, C12 & C15 Assembled in the USA Includes Custom TapeMat® and ShowerMat™ Please be aware local codes may require this product and/or the thermostatic control to be installed or connected by an electrician. Please leave this manual with the end user.
Read this Manual BEFORE using this equipment. Failure to read and follow all safety and use information can result in death, serious personal injury, property damage, or damage to the equipment. Keep this Manual for future reference. Floor heating mats are a simple way to heat an indoor space. This instruction manual is provided as a guide to installing TapeMats, including design considerations, installation steps, limitations, precautions, and floor covering guidelines.
Expected floor temperature Heating performance is never guaranteed. The floor temperature attainable is dependent on how well the floor is insulated, the temperature of the floor before start up, and the overall thermal drain of the floor mass. Insulation is required for best performance. Refer to Phase 4 for important design considerations. These are the three most common installations: 1.
Table 1 As with any electrical product, care should be taken to guard against the potential risk of fire, electric shock, and injury to persons. The following cautions must be observed: Local building or electrical codes may require modifications to the information provided. You are required to consult the local building and electrical codes prior to installation. If this information is not consistent with local building or electrical codes, the local codes should be followed.
ALWAYS make sure all electrical work is done by qualified persons in accordance with local building and electrical codes, Section 62 of the Canadian Electrical Code (CEC) Part I, and the National Electrical Code (NEC), especially Article 424. ALWAYS use copper only as supply conductors to the thermostat. Do not use aluminum. ALWAYS seek help if a problem arises.

STEP 1.2 Record the product information in Table 4. Give this information to the homeowner to keep in a safe place. The Mat model number, serial number, voltage, and resistance range are shown on a nameplate label attached to the power leads. White or Blue Lead Ground Lead Black Lead Black wire to COM Red wire to Ω Do not remove this nameplate label. The electrical inspector will need to see this. STEP 1.

Phase 2 - Electrical Rough-in To prevent the risk of personal injury and/or death, make sure power is not applied to the product until it is fully installed and ready for final testing. All work must be done with power turned off to the circuit being worked on. STEP 2.1: Circuit Breaker (Overcurrent Protection) TapeMat(s) must be protected against overload by a circuit breaker.
STEP 2.3: Bottom Plate Work Drill or chisel holes at the bottom plate as indicated. One hole is for routing the power lead conduit and the other is for the thermostat sensor. These holes should be directly below the electrical box(es). Power lead conduit Wire Clip Sensor wire If going in to an existing wall, cut out dry wall and chisel out bottom plate to route wires to control. Power lead Sensor wire STEP 2.
Phase 3 - Mat Installation STEP 3.1: Floor Cleaning The floor must be completely swept of all debris including all nails, dirt, wood, and other construction debris. Make absolutely sure there are no objects on the floor which might damage the TapeMat wire. Wet mop the floor at least twice to ensure there is no dirt or dust. This will allow proper bonding of the mortar. STEP 3.2: Position the Power Leads Carefully cut the tie binding the power lead coil. Do not nick the braid covering the power lead.
STEP 3.4 Test Fit the Mat Roll out the mat, flipping it as needed to cover the intended area. This is very important to ensure proper fit before proceeding. If there is too much mat for the area it cannot be cut shorter and heating wire cannot be routed into a wall, under baseboards, or other similar areas. All heating wire must be embedded in the floor mortar. STEP 3.
Cu t ma t Use hot glue to attach wire to the floor. M remat m ov esh ed Roll over Roll-over Turn. Fill-in Technique. Installing in front of cabinets and toilets: Install mat right up to the face of the cabinet as shown above. Mat can be installed under tile to within 6" from the wax ring, and can slightly underlay the foot of the toilet if need be (approximately 20" from wall).
STEP 3.6 Secure the Mat to the Floor Lay the mat down flat. Ensure it fits well and has no folds or large ripples. Securing the mat as flat as possible will help make a smooth surface for spreading mortar. Chisel a path for the power lead and factory splice. If the mat comes with double-sided tape already attached, remove the liner along one edge and press the tape down. Remove the liner along the other edge and press the tape down, pulling lightly on the mat to keep it flat.

STEP 3.9 Feed the sensor wire to the SunStat thermostat electrical box leaving at least 6"-8" of free lead length in the box. Weave the sensor at least 1' into the mat area, halfway between the heating wires, and secure it using hot glue. Do not cross the heating wires.
STEP 3.10: Shower Application Acceptance of this application must be verified by the local inspector or authority having jurisdiction (AHJ). Locate power lead and factory connection to heating wire at least 1’ outside the shower area. Shower Curb Tile Avoid sharp bends in heating wire Thin-set Mortar Factory Splice Heating Wire 1. 2. 3. 4. Refer to diagrams in the Appendix, especially pages 26 & 27. Never install TapeMat or ShowerMat in shower walls (or any other wall).
Take photographs of the mat installation. This can be very useful later during remodel work to help avoid possible wire damage. Keep the photos with this installation manual and provide to end user upon completion. Phase 4 - Floor Coverings It is recommended to consult with professional flooring installers to make sure proper materials are used and proper installation techniques are followed.
Type of Construction Mortar Applications: Thin-set and thick-set (self-leveling) mortar applications are illustrated below and to the right. a. If a backer board or plywood sheeting is used to strengthen the floor, or if the mat will be placed directly onto the slab, install TapeMat in the thin-set mortar bond coat above these materials. b.

Connecting Multiple Mats To prevent the risk of personal injury and/or death, do not perform any electrical work unless qualified to do so. Work should be done with great care and with power turned off to the circuit being worked on. Follow all local building and electrical codes.
Troubleshooting Guide If problems arise with the TapeMat or its related electrical components, please consult this troubleshooting guide. If not qualified to perform electrical work, it is highly recommended that a qualified, licensed electrician be hired. Any electrical troubleshooting work should be performed with the power removed from the circuit, unless otherwise noted.
