Installation of the drive unit onto the rail 

 

Step 1:

 Take the box with the drive unit close to the upper end of the rail. Open the box so 

that the rails and trolleys are on the top of the box. Take out the drive unit and place it on 
the floor so that it is standing upright 
 

 

 

Step 2:

 Take off the wooden plates on each side. Put the drive unit on the floor (use 

protection under it so not to scratch it). Then 2 people should lift the drive unit on the rails 
and attach the installation rails to the top of the installed rail on the staircase. Then slide 
the drive unit down until it reaches the top of the installed rail. Use the handwheel to drive 
the unit onto the installed rail so that the lower rail passes entirely through the lower trolley.
