ENG 1.3 Remember to measure resistance I WARNING: Shock and fire hazard! The resistance should be measured between the two conductors, white and black. Compare this resistance reading to the resistance specified in table below. The value should be within -10% to +10%. If you get a different reading, contact to the distributor. Also, measure the resistance between the white, black and shielding/ground wire. Both should read infinity. If you get a different reading, contact to the distributor.
ENG 3 DESIGNING FLOOR HEATING AND CHOOSING THE PRODUCT Figure 1.: Embedded in concrete 3.1 Design the Installation 1 2 ENG 2.2 BVF WFD typical installations and applications Step 1: Measure the heated area Determine the heated area of the floor where there are no permanent fixtures or furniture such as showers, toilets, vanities, or cabinets. Measure the heated area of the floor. For example, in Figure 3.1, the area of the bathroom is 8.75 m2.
3.2 Confirm Your Product Selection Confirm that your BVF WFD length is not larger than the heated area. Following the example from Figure 2, if the heated area is 6.45 m2, select the optimal cable length and cable spacing based on the figures below.
ENG 3. Install floor sensor i Important: Tools and materials required If using a floor temperature sensing thermostat, install the sensor now, preferably in conduit tube, or directly to the subfloor. It is recommended that the sensor be installed in conduit tube. This will allow the sensor to be easily replaced in the unlikely event of failure. The sensor and/or tube needs to be installed between the thermostat wall box and the sensor position.
ENG I ENG 6. Begin laying the BVF WFD heating cable 9. Embed the heating cable WARNING: NEVER CUT OR SHORTEN THE HEATING CABLE Start by placing the heating cable such that the connection point and the temperature sensor are in their intended positions and bring the power cable to the thermostat or connection box. Avoid walking on the heating cable. If this is not possible, use shoes with soft soles. Use BVF fixing strips or mesh for fixing the cable on the floor.
ENG 5.2 Heating cable resistance test Please refer to Step 5. This test measures the resistance of the BVF WFD heating cableand is used to determine circuit integrity. 14. Record information 1. Set your multi meter to the 200 or 2000 ohm range. 2. Connect the multi meter leads to the black and white cold lead wires. 3. Compare this resistance reading to the resistance specified in the Product Selection. The value should be within -10% to +10%. If you get a different reading, contact to the distributor.
