TRACK ASSEMBLY

1.Assemble both tracks by installing the track spacers (Figure 2).

2.Install the idler assemblies onto the wall end of the tracks. One idler assembly is set up with a coupling sprocket on each end, and the other idler is set up with only one coupling sprocket.

3.Slide the slider assembly into both tracks from the open end. Be sure that the take-upbolt is facing the open end of the track.

4.Install the idler roller assemblies onto the open end of the tracks.

5.Install the chain, use the take-upbolt to adjust the chain tension to allow about 3" sag in the center (remove links if necessary).

6.Determine which side of the door the operator will be mounted on and install the track with the double idler on that side at the center of the opening.

7.Install the track assembly with the single idler on the other side of the center of the opening. Brace the tracks appropriately.

CONNECT TRACKS

1.Determine the length of the shaft needed to couple the two tracks together and cut the shaft provided to that length. Slide two bearing assemblies on the end of the shaft.

2.Install a 48B14 sprocket on each end of the shaft using the

(2) 1/4" x 1-1/2"roll pin provided (Figure 1).

3.Use a tape measure to set the slider assemblies the same distance from the wall.

4.Couple the shaft between the two idler assemblies by butting the 14 tooth sprockets together and connect with a #40 chain and master link (Figure 2).

INSTALL OPERATOR

1.Install the operator using the appropriate manual.

2.Determine the length of shaft needed to connect the operator to the double idler assembly and cut the shaft provided to that length.

3.Install the last 48B14 sprocket to one end of the extension shaft with the 1/4" x 1-1/2"roll pin provided (Figure 3).

4.Slide the last two bearing assemblies onto the end of the shaft. Place one of the bearings in the center of the shaft. The other bearing should be placed as close to where the operator driven sprocket will be.

5.Remove the 50B12 sprocket from the operator and replace it with the 50B35 sprocket provided. Install the 50B12 sprocket on the extension shaft just installed.
