5.6.5 Spring Tube Assembly Replacement

For an exploded view of the spring tube assembly, refer to section 6.1.7.
1. Elevate the elevating base to the upper limit of travel.
2. Elevate the canopy to the service position, about halfway up so that the black oxide shipping screw is
centered in the horizontal slot, which is about midway up on the outside of the dovetail rail.
3. Turn off the unit and unplug it from the wall.
4. Slide up the decorative strip in the dovetail rail slot to expose lower end cap screw. (A piece of adhesive
tape on the decorative strip can help to move it.)
5. Remove the lower end cap.
6. Remove the hole plug from the back of East lift rail. (Refer to "Figure 5-24 Disconnecting Heater Door
Cable".)
7. Rotate the spring tube assembly until the setscrew hole and lower securing hole are visible from the access
hole in the back of the inner rail. Insert a 2 mm hex wrench through the small hole in the back of the inner
rail through the spring tube and back into the rail to temporarily secure the spring tube assembly to the
inner rail.
8. Unscrew the setscrew in the door cable conical cap until it is possible to separate the door cable cap from
the spring tube. Do not remove the setscrew.
9. Secure a length of string to the cross-hole in the spring tube. The string should be long enough to allow the
spring tube to be removed from the bottom of the rail assembly. Firmly secure the other end of the string.
This string will be used to lift the new spring tube assembly into place.
10. Remove the wrench from the cross hole in the spring tube and lower the tube to the bottom of travel with
the string.
11. Remove the lower M5 nut from the spring tube assembly at the bottom of the rail.
