SmartJack V4.0 Installation
Step 4 Hang the motor/gearbox assembly on the chain as pictured (figure 3) Position the unit so the operator is level and plumb and the chain is aligned properly before securing the unit to wall (figures 4-6). Important! When positioning the operator for final mounting to the wall, the chain should be snug and plumb (figure 4). Use the gearbox housing as your reference to ensure the unit is mounted level and plumb. (figures 5-6) DO NOT use the stainless base plate for reference.

When initially fastening unit to wall, place the fasteners/lags in the center of the vertical slotted hole. This will allow you to make adjustments to the chain tension. (figure 8) Once the operator is positioned properly, relocate or add the fasteners/ lags to the bottom of the slotted holes to prevent the unit from moving up from continual operation. (figure 9)
Lag
Manual Disconnect Installation The manual disconnect chain is attached to the brake lever located on the front of the motor/fan assembly. (figure 9) After installing the motor/gearbox, remove the packaging and allow the chain to drop. Then, mount the chainkeeper bracket on the wall with lags as shown. Make sure the bracket will hold the disconnect chain in place while holding the brake lever in the manual (down) position. When the disconnect is disengaged, the door should operate manually.

A bearing plate should be installed to support the torsion shaft once the operator has been installed (figure 7). This prevents the shaft from deflecting causing chain issues.
