The electric antifreeze kit allows you to protect your Truma AquaGo Comfort or Truma AquaGo Comfort Plus from freezing without the use of LPG. Maintains AquaGo comfort or comfort plus frost down to -4°F (-4°C). Works on electricity only (12V DC): It will work without LPG even in standby mode when the burner is off or while driving when the LPG cylinders are closed. Draining the water is not necessary. Plug and Play: Easily adapts in just a few minutes. The electric antifreeze kit is inserted into the "easy drain lever" and connected to the wiring harness. The Truma AquaGo Antifreeze Kit is not an alternative to propane for heating water. It is intended solely to prevent the Truma AquaGo from freezing when traveling or when the system is not powered by propane. The Truma AquaGo Antifreeze Kit heats the water inside the AquaGo while activating the circulation pump to continually move warm water throughout the system.
