1. Introduction
This manual provides essential information for the safe and efficient operation of your Truma AquaGo Electric Antifreeze Kit. Please read this manual thoroughly before installation and use, and retain it for future reference.
The Truma AquaGo Electric Antifreeze Kit is designed to protect your Truma AquaGo Comfort or Truma AquaGo Comfort Plus water heater from freezing. It operates on 12V DC electricity, eliminating the need for LPG to prevent frost damage. This kit maintains the AquaGo system frost-free down to -4°F (-20°C), ensuring functionality even in cold conditions. It is intended solely for freeze protection and is not an alternative to propane for heating water for consumption. The kit works by heating the water inside the AquaGo and activating the circulation pump to move warm water throughout the system, preventing ice formation.
2. Safety Information
WARNING:
- Always disconnect power before performing any installation, maintenance, or troubleshooting.
- Installation should be performed by a qualified technician to ensure proper function and safety.
- Ensure all electrical connections are secure and properly insulated to prevent short circuits or electrical hazards.
- This kit is for freeze protection only. It does not replace the primary heating function of the Truma AquaGo unit.
- Do not operate the Truma AquaGo with the flue plug inserted when using propane for water heating. The flue plug is only for use when the antifreeze kit is active and the propane burner is off, especially during travel in freezing conditions.
3. Package Contents
Verify that all components are present and undamaged before proceeding with installation.

4. Setup and Installation
The Truma AquaGo Electric Antifreeze Kit features a plug-and-play design for straightforward installation. However, professional installation is recommended.
4.1 Tools Required
- Basic hand tools (e.g., screwdriver, wire strippers/crimpers if modifying wiring)
- Multimeter (for verifying power connections)
4.2 Installation Steps
- Prepare the AquaGo Unit: Ensure the Truma AquaGo unit is powered off and cooled down. Close any LPG supply valves.
- Locate the Easy Drain Lever: Identify the "easy drain lever" on your Truma AquaGo Comfort or Comfort Plus unit.
- Insert Antifreeze Kit: The electric antifreeze kit is designed to be inserted into the existing "easy drain lever" mechanism. Carefully align and insert the heating element and its housing.
- Connect Wiring Harness: Connect the provided wiring harness to the antifreeze kit and then to the designated connection point on your Truma AquaGo unit. Refer to your AquaGo unit's main manual for specific wiring diagrams if needed. The kit operates on 12V DC.
- Secure Connections: Ensure all connections are firm and secure.
- Power On and Test: Restore 12V DC power to the Truma AquaGo system. The system may require a reboot of the control panel to recognize the newly installed antifreeze kit. Monitor the system for proper operation.

5. Operating Instructions
The Truma AquaGo Electric Antifreeze Kit is designed for automatic operation once installed and powered.
5.1 Activating Freeze Protection
- Ensure the Truma AquaGo unit has 12V DC power supplied.
- The kit will automatically activate when ambient temperatures approach freezing, circulating warm water within the AquaGo to prevent ice formation.
- This system allows for freeze protection without the need to drain the water system or use LPG, even when the main burner is off or during travel.
- If traveling in freezing conditions, it is recommended to insert the flue plug (if provided) into the AquaGo's exhaust flue to protect against wind chill, ensuring optimal performance of the antifreeze kit. Remember to remove the flue plug before operating the AquaGo with propane.
5.2 Important Considerations
- The antifreeze kit is a supplementary system for freeze protection, not a primary water heater.
- Continuous 12V DC power is required for the kit to function.
- The kit is effective down to approximately -4°F (-20°C). In extreme cold below this temperature, additional winterization measures may be necessary.
6. Maintenance
The Truma AquaGo Electric Antifreeze Kit requires minimal maintenance.
- Regular Inspection: Periodically inspect the heating element and wiring for any signs of wear, damage, or corrosion.
- Cleaning: If the heating element appears to have mineral deposits, it can be carefully removed and cleaned according to the Truma AquaGo main unit's descaling instructions. Ensure the unit is powered off and water drained before removal.
- Storage: If the RV or vehicle is stored for an extended period in freezing temperatures without power, it is still recommended to drain the entire water system, including the Truma AquaGo, to prevent damage.
7. Troubleshooting
If you encounter issues with your Truma AquaGo Electric Antifreeze Kit, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| Antifreeze kit not activating. | No 12V DC power. Control panel not recognizing kit. Ambient temperature not low enough. | Check 12V DC power supply to the AquaGo unit. Reboot the Truma control panel. Verify ambient temperature is below activation threshold. |
| Water still freezing despite kit operation. | Extreme cold beyond kit's capacity. Insufficient water circulation. Faulty heating element. | Consider additional winterization or draining the system in extreme conditions. Ensure AquaGo pump is functioning correctly. Contact Truma support for inspection/replacement. |
| Error message on Truma control panel. | Connection issue or component failure. | Refer to your Truma AquaGo main manual for specific error codes. Check wiring connections. |
If problems persist, contact Truma customer support.
