The actuator types FlowCon FNR.0.2,
FNR.0.2-EQ and FNR.0.3 are electrical ac-
tuators. FNR.0.2 and FNR.0.2-EQ are both 24V
modulating and FNR.0.3 is 2-position / 3-point
floating.
Fitting and Re-tting
Do not connect power to the actuator unless
the actuator is already fitted on the valve
and NEVER install the actuator in closed
position - this may damage the valve.
Actuator is supplied in open position to
ensure easy commissioning of the system.
Mount the actuator on the valve and finger
tighten the connection union. Do not use ad-
ditional tools. In case the actuator will have to
be removed, it is recommended to manually
open the actuator for easier removal. Hereaf-
ter finger loosen the connection union. Again,
no need for additional tools. Please make sure
that the actuator is manually opened, before re-
fitting it on the valve.
Orientation
Upside-down installation is allowed along with
the standard horizontal and vertical installation.

Start-up Sequence
When power to the actuator is turned on, the
actuator will automatically calibrate to deter-
mine closing point and stroke length of the in-
sert. Hereafter it will proceed to normal opera-
tion mode (according to control signal).
Manual Override
Before performing override, please turn off the
power supply. Lift the silicone cap on top of the
actuator to get access to manual override. Man-
ual override is performed with a 4 mm (~5/32”)
hex key. Counter-clockwise turning will open the
valve and clockwise turning will close the valve.
