To install the nVent RAYCHEM E507S-LS Line Sensing Thermostat, follow these steps:
1. Verify that the thermostat is suitable for the area where it is to be installed.
2. Check the line voltage and the heat-tracing load to ensure that the thermostat ratings are not exceeded.
3. Mount the unit using unistrut or the RAYCHEM universal mounting bracket (UMB-263757) in a position that prevents condensation from draining into the enclosure from the connecting conduit.
4. Position the sensor bulb in the lower quadrant of the pipe, at least three feet from pipe supports, valves, or other heat sinks. Protect the capillary from kinks or bends less than 1⁄2 inch in radius.
5. Tape the bulb firmly to the pipe with AT-180 aluminum tape, ensuring there is no air space between the bulb and pipe. Do not overlap the bulb and heating cable with the same piece of AT-180 tape.
6. For metal-tank-wall sensing, use the BCK-35 bulb clamp (purchased separately) and install it per the provided instructions. Ensure there is no air space between the tank wall and the bulb. For installation on plastic tanks, contact nVent for further assistance.
7. Set the thermostat dial to the desired temperature, then finish wiring.
8. Complete insulating. Do not turn the system on until the bulb is covered with thermal insulation.
9. Fill the piping or tank. Once the thermostat has begun to cycle, check the fluid temperature with an immersed thermostat or an accurate temperature indicator. Adjust the dial setting if necessary.
Please refer to the nVent RAYCHEM E507S-LS Line Sensing Thermostat Instruction Manual for more detailed instructions and diagrams.
