Question:

The Chill Cube 18k. I do not see where the installer has to install a freese sense? How does it work?

Hey Donny,

The Furrion Chill Cube # FR99TD doesn’t use a separate freeze sensor like the older RV AC units you might be used to installing. There’s no probe to mount, no extra wiring, and nothing missing from the installation steps. Everything is handled internally with built-in sensors and the variable-speed compressor that adjusts automatically to prevent the coil from freezing.
