Start-up
Danfoss RA
The Danfoss valve bodies have elongated notches (1)
around their circumference, which also ensure that the
adapter is properly seated when it snaps on.
During installation, make sure that the pins inside
the adapter (2) are lined up with the notches (1) on
the valve. Make sure that a suitable adapter for
the valve is properly clipped on.
After clipping the adapter onto the valve body, fix it using
the provided screw and nut.
