10. Remove the Display head assembly by following the steps in “Display Head Removal” on page 7-17.
11. Remove the screws that secure the connection panel (2.5 mm hex key) at the bottom of the electrical
enclosure. Remove the two screws (2.5 mm or 3 mm hex key) that secure the canopy motor/gear box to
its mounting plate and remove the motor/gear box.
12. While holding on to the lift rail with one hand, use a 4 mm hex key to tighten (CW) the intermediate stop
set screw until the screw bottoms out and the inner rail is free, then carefully let the lift rail extend to its
full height, releasing spring tension. It may be necessary to pull gently on the canopy to free the
standoffs from the rail.
13. Hold on to the upright, and using a 4 mm hex key, remove the 2 screws in the holes in the lower side of
the upright. Remove the entire upright assembly.
You can disconnect the electrical connector and ground to completely remove the upright or, if you wish,
there is enough slack in the wiring to allow you to work on the upright on a table or bench close to the
device without disconnecting the electrical or ground connection. Refer to section 7.4.3 for right rail internal
repairs and section 7.4.4 for reassembling the right upright.
7.4.2 Removing the Left Upright
Refer to “Figure 7-1 Heater Housing Cover and Soffit” and “Figure 7-23 Rail Decorative Strips, End Caps, and
Wire Cover”.
1. Lock the rails in the intermediate position by raising the canopy then slowly lowering it until the rail
locking screws align with the horizontal oblong holes in the rails. Lock both rails by turning the screws
CCW (4 mm hex key) until they lock the rails in place. Power down the device and unplug it from the
power outlet.
2. Using a small straight blade screwdriver, remove the 6 arrow clips that secure the soffit beneath the
rear of the canopy (refer to Figure 7-1) and remove the soffit.
3. Using a 2.5 mm hex key, remove the 4 screws and washers that secure the heater housing cover to the
heater door bracket and remove the cover.
4. Remove the left inside cover by removing the 2 screws and nuts (2 mm hex key, 5.5 mm wrench) that
secure it around the electrical cables.
5. Remove the two flat head screws (3 mm hex key) that hold the canopy bracket to the lift rail.
