1. Introduction
Thank you for choosing the Farm Innovators H-429 Sub Tank Deicer. This device is designed to prevent water from freezing in livestock watering tanks, ensuring a continuous supply of unfrozen water for your animals during cold weather. Please read this manual thoroughly before installation and operation to ensure safe and efficient use.
2. Important Safety Information
WARNING: Failure to follow these safety instructions may result in fire, electric shock, injury, or property damage.
- Always ensure the deicer is fully submerged in water before connecting it to a power source.
- Use only with a properly grounded 120V AC outlet. Do not use with ungrounded outlets or adapters.
- Do not operate the deicer if the power cord is damaged or frayed. Inspect the cord regularly.
- Keep the power cord out of reach of animals to prevent chewing or damage. The unit features an anti-chew cord protector, but additional measures may be necessary.
- Ensure the deicer is placed at the bottom of the tank and is stable. The caged barrier helps protect the heating element.
- Disconnect the deicer from the power source before performing any maintenance, cleaning, or when removing it from the tank.
- This product is designed for use in North American electrical systems (120V AC). Using it in regions with different voltage standards (e.g., 220-240V AC in Europe) without a proper voltage converter will render it useless and potentially dangerous.
- Do not use the deicer in tanks smaller than recommended or in plastic containers that are not rated for use with heating elements, as this may cause warping or melting.

5. Setup and Installation
- Inspect the Unit: Before installation, carefully inspect the deicer and its power cord for any signs of damage. Do not use if damaged.
- Placement in Tank: Place the deicer at the bottom of the watering tank. Ensure it is fully submerged in water. The caged design allows it to rest securely.
- Water Level: Maintain an adequate water level in the tank. The deicer must always be fully submerged when operating.
- Cord Management: Route the heavy-duty power cord away from animals to prevent them from chewing on it. Secure the cord along the side of the tank or fence if necessary, ensuring it does not create a tripping hazard.
- Electrical Connection: Plug the deicer into a grounded 120V AC outdoor-rated electrical outlet. It is recommended to use a Ground Fault Circuit Interrupter (GFCI) protected outlet for added safety.

6. Operation
The Farm Innovators H-429 Deicer operates automatically:
- Once plugged in and fully submerged, the deicer's internal thermostat will monitor the water temperature.
- The heating element will activate automatically when the water temperature drops to near freezing (approximately 35°F / 1.7°C).
- It will continue to heat the water until it reaches a safe temperature above freezing, then automatically shut off.
- This cycle repeats as needed to prevent ice formation.
- Regularly check the water level to ensure the deicer remains fully submerged during operation.

7. Maintenance
- Regular Cleaning: Periodically remove the deicer from the tank and clean any mineral deposits or algae buildup from the heating element and cage. Descaling agents designed for water heaters can be used, following product instructions. Ensure the unit is unplugged and cool before cleaning.
- Cord Inspection: Regularly inspect the power cord for any signs of wear, cuts, or damage. Replace the unit if the cord is compromised.
- Storage: When not in use, especially during warmer months, clean the deicer thoroughly, dry it, and store it in a dry, safe place away from direct sunlight and extreme temperatures.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Deicer not heating | No power to outlet Thermostat not activated (water not cold enough) Faulty unit | Check power outlet and circuit breaker. Verify water temperature is near freezing. If power is present and water is cold, unit may be faulty; contact support. |
| Circuit breaker trips | Overload on circuit Short circuit in deicer or cord | Ensure deicer is on a dedicated circuit or one not overloaded by other appliances. Inspect cord and unit for damage. Discontinue use if damage is found. |
| Water still freezes | Deicer not fully submerged Extreme cold exceeding unit capacity Faulty thermostat | Ensure deicer is always fully submerged. In extremely low temperatures, some surface ice may form, but the deicer should keep a hole open. Consider additional insulation for the tank. If the unit is not activating in freezing temperatures, contact support. |
