18. Install drive belt # 10 and clamp the two open ends equally in the lower belt bracket # 3, cutting
is required for desired length. C/P doors need clamping in upper belt bracket # 25, as well,
see Fig. 4. Move the doors from closed to open position and adjust the belt brackets so that belts
are parallel to each other looking from top.
19. Tension the drive belt with the tension block # 5 so that the upper and lower sides can be
Squeezed, together using moderate pressure. (A loose belt can jump teeth. An overly tightened
belt is noisy.)
20. Install the motor operator unit assembly # 20. It is extremely important that the motor axle is,
parallel to the drive pulley axle. Rubber pads are supplied to shim between, header
Angles, and drive unit box assembly. This will reduce noise and vibration.
21. Lower the motor mounting plate to its bottom position. Install the motor belt # 19
over the motor pulley and slide the motor control box into the correct position. Hand-tighten the
clamping bars. Correct the pulley alignment with a straight edge. This is the most critical part of
the installation to reduce belt wear, noise and vibration.
22. Tension the motor belt # 19 by means of adjusting the wing nuts on the motor mounting plate
equally. Do not over tighten the motor belt.
23. Secure the motor control box by tightening the clamps and doweling. Move the doors by hand to
verify proper operation.
24. Start the electrical set up.
