Do not use heavy equipment, such as a hammer, to install the SeVG Plus
actuator as it may damage the actuator housing and lead to failure of the
actuator.
Do not apply force to the motor rod. Hold the motor rod end by the ats and
use a proper key during tightening of the valve pin holder to the motor rod
end thread. Permanent damage to the anti rotation mechanism will occur if
