Step 1. Check the door
After the door is installed, adjust the torsion spring, ensure manually opening or
closing the door is flexible without stagnation, observe the rotation direction of the
rope sheave which should be consistent with the opening and closing direction of the
industrial door operator.
Step 2. Determine the installation position
Consider the boundary dimension and installation direction of the door operator,
determine the position of the mounting bracket, mark the insert cavity position, drill the
screw hole and fix the mounting bracket. (The mounting bracket can be fixed inside or
outside the door operator, recommended to be installed inside for the convenience of
disassembly of the door operator).
