This is how you install a Firgelli AutoTV LIFT (www.Firgelliauto.com) mechanism into a cabinet. 1st from the box assemble the tv lift using the instruction in the box, these lifts are the simplest tv lift mechanisms we have found so far and the prices are really good. once assembled it should look like this.
The Software I used for this is Google Sketchup, its free and the best easiest 3D drawing software I've ever ued
Step 1: TV Lift Step 2
now add the bas of the cabinet and the back wall, the TV lift will screw onto the back wall in 4 places, make sure the back wall is good solid thick wood
Step 2: TV LIFT Cabinet Next Step
Now add the sides of the cabinet and the tv. NOTE adjust the position of the tv on the LIFT mechanism using the different screw holes on the TV LIFT bracket. You need to position the TV so that ideally the top of the TV sits just below the roller on the top of the TV Mechanism. This is so that when the TV is lifting its the Rollers that push the Lid open and not the TV.
Now you need to make the drawers shorter which is simple enough but allow at least 1" between the tv face and the back of the drawer to be safe
add the top of the cabinet but with a pocket cut-out for the tv to raise out of, allow at least 1" possibly 2" around the edges so the tv clears the top when its raises up and down
Step 5: TV LIFT Add the Lid
Now add the lid, this can be the piece you already cut out or a new piece if you want it to fit tightly, hinge it at the back. Note that the rollers on the top of the TV LIFT mechanism are what will lift the lid up and down as the tv raises up and down, the rollers are positioned so that when the tv is raised the lid is at about 88degs which allows gravity to close the lid when the tv drops
Step 6: TV LIFT MECHANISM COMPLETE
Now the cabinet is done, this is what it will look like when finished, note on the Vector motions TV LIFT you can program the lift to stop where you want it so that just as the bottom of the tv clears the top of the cabinet you can stop the tv there. Once programmed the TV will always stop in that position every time you press the M button on the remote control. To buy a TV lift go to www.Vectormotion.com
