1. Raise the canopy to the intermediate lock position, then lock it in place by loosening the rail locking
screws on the outside of both uprights so that their heads engage the holes in the uprights. Shut off the
device and disconnect the power cord.
2. Using a small straight blade screwdriver, remove the 6 arrow clips that secure the soffit beneath the
rear of the canopy 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 bracket and remove the cover.
4. Disconnect the 2 electrical connections to the heater housing.
5. Remove the right inside cover. Using a 2 mm hex key and a 5.5 mm wrench, remove the 2 screws and
nuts that secure the right inside cover.
6. Remove the steel tube that routes the door cable into the extrusion. Use a 3 mm hex key to remove the
screw in the front cable clip. Use a 2.5 mm hex key and 7 mm wrench to remove the screw and nut in
the back cable clip.
7. Disconnect the heater door cable. The cable end is accessed through the two holes on the back of the
lift rail. First pry off the hole plug, then rotate the plastic tube so the hex head screw securing the
conical cap faces the rear. Push a small hex key or screwdriver through the small lower hole in the rail,
through the lower hole in the plastic tube inside the extrusion, and back through the rail on the other
side of the tube to hold the tube in place. Insert a 2 mm hex key through the larger hole to loosen the
screw that fastens the conical cap to the plastic tube. Pull the cap out of the rail.
8. Using a 10 mm wrench remove the 4 nuts on the housing bracket that secure the entire assembly to
the uprights. Grasp the canopy with both hands and raise it about ½” until the keyhole disengages.
Remove the canopy/heater assembly.
To reinstall the canopy reverse steps. Take care not to pinch the electrical cables.
