In case the actuator will have to be removed, it is recommended to
electrically open the valve for easier removal. Thereafter reverse the
procedure (3) and turn the snap ring clockwise until the actuator is
loosened and (4) lift the actuator up. No additional tools are needed.

NB! Do not remove the cover from actuator. Opening the cover will
void warranty.
Upside down installation is allowed (although not recommended) along
with the standard horizontal and vertical installation.
When the power is turned on, the actuator will automatically calibrate
to determine closing point of the valve. At first start-up, please enter the
programming menu to set actuator settings.
Start-up sequence
When the power is turned on, the actuator will automatically calibrate
to determine the closing point of the valve. Calibration can take up to 10
minutes depending on the valve's position at the start up. During the
calibration, the actuator display will show "
CAL
". Thereafter it will
proceed to normal operation mode (according to control signal).
If no control signal is detected, flush is started if enabled in the
programming menu (enabled by default), opening the valve to 5/6 of
fully open. Actuator display will show "
FLUSH
" until the control signal is
detected.
At first start up please enter the programming menu to set actuator
settings. See Settings sections for more information.
