2. Important Safety Information
Please read and understand all safety instructions before installing or operating the FrostGuard heating cable. Failure to follow these instructions may result in electric shock, fire, or property damage.
- Ground-Fault Protection: A 30-mA equipment or 5-mA personnel ground-fault protection device (GFPD) must be used on each FrostGuard heating cable branch circuit. This is a critical safety requirement.
- Electrical Supply: Ensure the electrical supply matches the cable's voltage (120V).
- Insulation: Always cover the installed heating cable with appropriate pipe insulation to ensure efficient operation and safety.
- Avoid Overlapping: While the cable is self-regulating and designed to prevent overheating, avoid excessive overlapping or tight coiling during installation to optimize performance and longevity.
- Damaged Cable: Do not use if the heating cable or plug is damaged. Contact a qualified electrician for inspection or replacement.
- Intended Use: This product is designed for pipe freeze protection and roof/gutter de-icing. Do not use for purposes other than those specified.
- Qualified Personnel: Installation should be performed by qualified personnel in accordance with local electrical codes.

5. Setup and Installation
Proper installation is crucial for the safe and effective operation of your FrostGuard heating cable. Follow these steps carefully:
- Inspect the Cable: Before installation, visually inspect the heating cable for any signs of damage. Do not install a damaged cable.
- Prepare the Pipe: Ensure the pipe surface is clean and dry. The cable can be installed on metal or plastic pipes.
- Attach the Cable:
- For metal pipes, run the cable straight along the bottom of the pipe. Secure it every 12 inches with electrical tape or cable ties designed for heating cables.
- For plastic pipes, run the cable straight along the bottom of the pipe, then wrap the pipe with aluminum foil tape before securing the cable. This helps distribute heat evenly.
- For valves, spigots, or other irregular shapes, coil the cable around the component to ensure adequate heat coverage. Ensure the cable does not cross over itself excessively.
- Insulate the Pipe: After securing the heating cable, cover the entire pipe and cable assembly with at least 1/2 inch of approved pipe insulation. This is essential for energy efficiency and to prevent heat loss.
- Connect to Power: Plug the preassembled lighted plug into a 120V electrical outlet that is protected by a 30-mA equipment or 5-mA personnel ground-fault protection device (GFPD). The lighted plug will illuminate when power is supplied.

6. Operating Instructions
The nVent RAYCHEM FrostGuard heating cable is designed for automatic operation:
- Once plugged into a GFPD-protected 120V outlet, the cable will automatically sense the ambient temperature.
- The self-regulating technology will adjust the heat output to maintain the pipe temperature above freezing.
- The lighted plug serves as a visual indicator that the cable is receiving power. If the light is off, check the power supply and GFPD.
- For optimal energy efficiency, ensure the cable remains plugged in during freezing conditions.
7. Maintenance
The nVent RAYCHEM FrostGuard heating cable is designed to be maintenance-free due to its robust construction and self-regulating properties. No moving parts require lubrication or adjustment.
However, it is recommended to perform an annual visual inspection before the onset of cold weather:
- Check the cable and plug for any visible damage, cuts, or abrasions.
- Ensure the pipe insulation is intact and securely covering the cable. Repair or replace any damaged insulation.
- Verify that the GFPD is functioning correctly by pressing its "Test" button.
8. Troubleshooting
If your FrostGuard heating cable is not functioning as expected, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cable not heating / Lighted plug is off | No power to the outlet, GFPD tripped, or damaged cable/plug. |
|
| Pipes still freezing despite cable being on | Insufficient insulation, cable not properly installed, or extreme cold. |
|
| GFPD trips frequently | Moisture ingress, damaged cable, or faulty GFPD. |
