place the torsion bar on the floor and position the lifting parts
in order. place the spring anchor bracket onto the torsion bar,
positioning it approximately half way along.The cut off comer
should face the floor if mounted on the lintel, or if mounted on
the ceiling should face rearward, away from the lintel to allow
the panels to clear as the door operates, see Figure 37.
with single spring doors, slide a shaft collar against the spring
anchor bracket. The bearing flange in the spring anchor bracket
must face the spring. It may need to be reversed depending on
whether a left or right hand spring is supplied, see Figure 38.
The shaft collar is tightened against the bearing flange. Slide the
spring onto the torsion bar and over the shaft collar. A left hand
spring has a red winding plug, and should be fitted to the left
hand side of the spring anchor bracket. A right hand spring has
a black winding plug. The winding plugs should face away from
the spring anchor bracket, see Figure 39.
NOTE:
It is important to use 2 of the 4 1¼ inch square necked
bolts to secure each side bearing plates in position.
Refer to page 28 when adding spring tension.
