Quick guide from the manual
This document provides essential instructions for the installation of Danfoss RA 15/6T and RA 15/6TB conversion valves. The guide focuses on the physical connection of the valve body to the radiator and the subsequent attachment of the thermostatic sensor head.
Installation procedure
The installation process involves two main steps for both the RA 15/6T and RA 15/6TB models:

- Valve Body Mounting: Secure the valve body onto the radiator connection. Ensure the thread size matches your specific radiator setup (available in 1/2 inch or 3/4 inch variants depending on the model code).
- Sensor Head Attachment: Once the valve body is securely installed, align the thermostatic sensor head with the valve body. Push the sensor head onto the valve until you hear a distinct click, indicating that it is locked in place.
