2. Important Safety Information
Read all instructions before using this product. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Electrical Safety: Ensure the deicer is connected to a properly grounded 120V AC outlet. Do not use with ungrounded outlets or adapters.
- Extension Cords: If an extension cord is necessary, use only a heavy-duty outdoor-rated cord (minimum 12-gauge) that is specifically designed for outdoor use and rated for the deicer's wattage (1500 watts). Ensure connections are dry and protected from moisture.
- Cord Protection: The deicer is equipped with an anti-chew cord protector. However, regularly inspect the cord for any signs of damage, fraying, or animal chewing. Discontinue use immediately if damage is observed.
- Placement: Always place the deicer at the bottom of the water tank. Do not allow it to float or be partially submerged.
- Water Level: Ensure the deicer is fully submerged in water before connecting to power. Never operate the deicer in an empty or partially filled tank.
- Plastic Tanks: The caged barrier design makes this deicer safe for use in plastic buckets and tanks without risk of warping or melting.
- Maintenance: Disconnect power before performing any maintenance, cleaning, or inspection.
- Supervision: While designed for safety, periodic observation of the deicer and animals is recommended.

6. Operating Instructions
The Farm Innovators Submergible Water Tank Deicer operates automatically:
- Automatic Operation: The deicer is equipped with a self-regulating thermostat. It will automatically activate when the water temperature approaches freezing and deactivate once the water is above freezing. This ensures efficient operation and prevents unnecessary power consumption.
- Continuous Water Supply: The deicer maintains a small area of open water, providing animals with access to liquid water even in sub-freezing temperatures.
- Monitoring: Periodically check the water tank to ensure the deicer is functioning correctly and that animals have access to unfrozen water.

- Inspect Cord and Unit: Regularly inspect the power cord for cuts, abrasions, or other damage. Check the deicer unit for cracks, corrosion, or loose components. If any damage is found, discontinue use and replace the unit.
- Storage: When not in use (e.g., during warmer months), clean the deicer thoroughly, allow it to dry completely, and store it in a dry, safe place away from direct sunlight and extreme temperatures.
8. Troubleshooting
If your deicer is not functioning as expected, refer to the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Deicer is not heating. | No power to the unit. Faulty deicer. Thermostat not activated (water not cold enough). | Check power outlet, circuit breaker, and extension cord.
