Pre-setting
Danfoss pre-settable valve bodies incorporate easy
setting adjustment rings with clearly engraved setting
markers scaled from

and

. Setting values can
be set quickly and precisely, without the need for
tools, as follows:
- Remove protective cap or sensor element
- Lift setting ring
- Turn anti-clockwise to the desired engraved setting
value
- Allow setting ring to spring back into position
The preset level can be selected in 0.5 increments
between 1 and 7 (see chart on page 3 for flow rates).
At setting

the valve is fully open (flushing option).
