Right hand and left hand installation
You may install the rolling door operator to left or right side. Operator is normally delivered right hand. (View
from inside the opening), If you need to change it to the left processed as follows: undo the four screws on
the housing, then turn the upper housing 180° and ensure the chain hangs vertically, finally tighten the
screws. Make sure there is no clearance between upper housing and lower housing. If the operator has
pawl (see Table 3), turn the pawl 180° at the same time.
Install the rolling door operator to right side.
Right side sprocket bracket
Install the sprocket bracket on the wall or wall bracket horizontally; if the distance is not sufficient the bracket
angle may need to be adjusted (The installation angle can be adjusted to between 0° and 44°, ensure the
chain hangs vertically.)
