INSTALLATION
The ED STD3 is inserted from the lift shaft into the door frame so that the piston rod points
through a hole in the frame to the door and hits the closing lift door.
The landing door damper is screwed to the frame at three points:
2 fixing borings in the front plate
1 fixing boring in the rear flap of the casing.
IMPORTANT: Never tighten the screws of the front plate too much. This might distort the front
plate and thus block the piston rod.
It is imperative to fix the included counter plate (1) to the door – also when replacing the damp-
er. When the door is closing, the piston rod should hit the center of the counter plate.
For Thyssen/Stahl doors is used the rectangular counter plate made of hardened spring steel,
for Otis doors the round counter plate of tempered CrMoV steel.
Putting into operation
To achieve optimal damping close the door (pushing in the piston rod) several times to expel
any air left in the damping cylinder prior to installation.
Adjusting
With the piston rod fully extended grasp ONLY the knurled part (2) with a pair of pliers and turn
it. Important: Please make sure that you do not damage the polished surface of the piston rod!
With a damaged piston rod the damper will no longer work properly.
Turning clockwise: less damping
Turning anti-clockwise: stronger damping
Maintenance
The ED STD 3 damper does not require maintenance. In case of being soiled it is enough to
carefully clean the piston rod. By removing the cap (3) you can check the oil filling. If necessary,
refill oil.
