Installation walk-through for 045981

Lutron document 045981 gives ten steps, in the document's order, after the tools and fixings it lists.

The clearance, the check and the warning under a step are the document's own.

Tools

  • Tape measure
  • Small flat-blade screwdriver
  • #1 Phillips screwdriver
  • #2 Phillips screwdriver
  • Power drill and drill bits
  • Level
  • Pliers
  • 3/32 in (2.4 mm) hex key, included
  • WIN-DREC-TOOL recessed drapery installation tool, recommended

Fixings

  • Ceiling-mount cam locks, included; quantity varies with width
  • #8 cam lock screws, not included, to suit the structure
  • Shims for an uneven ceiling (not included)
  • Recess-mount brackets and #8 x 1 1/2 in (38.1 mm) wood screws, included
  • Recess-mount wood screws suit wooden members only
  • 1/2 in (12.7 mm) track-mounting screw for a recessed mounting bracket, provided
  • Pocket mounting screws (not provided by Lutron)
  • 4-pin terminal block (provided)
  1. Check the parts

    Lay out the drapery track, the terminal block and the ALAC-EDU-D105-PT drive with its end motor bracket. Add the cam locks for a ceiling-mount, or the recess-mount brackets and wood screws.

    A dual system has an extra track and drive. The guide shows a single-track, right-draw system.

    Warning: Risk of falling objects: fix the system securely as the mounting steps describe

  2. Ceiling-mount: fasten the cam locks

    Hold the track against the ceiling, parallel to the window or wall. Pencil a mark at each end.

    Fit a cam lock within 8 in (200 mm) of each mark and the next 16 in (400 mm) further in. Space the rest 16 in to 24 in (406 mm to 610 mm) apart, 16 in (406 mm) where non-sheer panels stack back.

    Use #8 screws suited to the structure, with shims where the ceiling is uneven.

    Clearance: End cam lock within 8 in (200 mm); next 16 in (400 mm) in; others 16 in to 24 in (406 mm to 610 mm)

    Check: All cam locks lie in one straight, level line

  3. Ceiling-mount: lock the track in

    Turn every cam lock lever to unlocked and lift the track against them. Starting at the center and working outward, turn each lever to locked until its tab bears on the track.

    Check: Every tab is against the track before the drive goes in

  4. Recess-mount: prepare the track

    Skip to step 6 if the track is ceiling-mounted.

    The track comes pre-drilled at 16 in (406 mm) centers. Slide a recess-mount bracket into the upper channel and line up its center hole with a track hole.

    Drop a screw through both to hold them. Turn the bracket 90 degrees, tighten both set screws with the 3/32 in (2.4 mm) hex key, and remove the screw.

    Repeat at every hole along the track.

    Clearance: Holes at 16 in (406 mm)

    Check: A bracket is locked at each pre-drilled hole

    Warning: The structure must carry the track, drive and fabric together. The installer adds blocking where none exists.

  5. Recess-mount: fix the track

    Position the track and drive a 1 1/2 in (38.1 mm) wood screw through each track hole and bracket into a wooden member.

    Inside a Lutron recessed pocket, use the 1/2 in (12.7 mm) track-mounting screw through the track and the recessed mounting bracket instead. The WIN-DREC-TOOL spaces the track evenly and guides the drill.

    Clearance: Pocket at least 1 1/16 in (27 mm) deep and 2 1/4 in (57 mm) wide

    Check: Pocket depth does not touch the fabric

    Warning: The wood screws supplied suit wooden members only. Other structures need the installer's own fasteners.

  6. Install the drive

    Choose slim orientation, recommended for fold style drapery, or original orientation. Line the drive's mounting flange up with the rail box tabs and drive shafts.

    Push it in until the tabs seat fully. Rotate the drive in the flange until the securing holes line up, keeping the harness free.

    Fit the securing screw.

    Check: Securing screw fitted and tight before the drapery is run

    Warning: The securing screw is what holds the drive safely

  7. Wire the drive

    Lock the breaker off or pull the fuse. Strip 2 in (51 mm) of jacket from the wall cable and 1/4 in (6 mm) from each wire.

    Clamp the wires in the 4-pin block (Common, Power, Open, Close) with a small flat-blade screwdriver, leaving about 1/16 in (2 mm) bare. Plug the block into the drive and tie the cables clear of moving parts.

    A stand-alone keypad or a QSE-IO interface (document 040391) switches the drive.

    Clearance: Strip 2 in (51 mm) jacket, 1/4 in (6 mm) per wire, 1/16 in (2 mm) exposed

    Check: Cables secured where they cannot foul the drapery

    Warning: Shock hazard: breaker locked off or fuse removed before wiring the block

  8. Hang the drapery panel

    Size the panel so its top and the track bottom sit about 4 in (101 mm) above the window casing. Leave 1/2 in to 1 in (13 mm to 25 mm) above the floor.

    Clip a pendant to each male auxiliary snap and hang it in its auxiliary carrier. Fasten the remaining snaps to the drive and idler snap brackets and the master carriers.

    The snap layout follows the draw: one-way, or center draw with butt or overlap closure.

    Clearance: 4 in (101 mm) above the casing; 1/2 in to 1 in (13 mm to 25 mm) above the floor

    Check: Snap layout matches the chosen draw and closure

  9. Power up and test pull-to-start

    Connect the power supply. Tug the leading edge gently toward close and let go, and the drive takes the panel fully closed.

    Wait 5 seconds after it stops, then tug toward open and let go. The drive runs it fully open.

    Check: The drapery reaches both ends on its own after each tug

  10. Test the keypad and troubleshoot

    Tap Close, wait 5 seconds after the panel stops, then tap Open.

    No response means no power at the drive: confirm the line voltage and every connection. A drive past its maximum continuous run time needs a 20-minute wait.

    A drapery that answers a tug but not the keypad lacks keypad power, so check its Common. One running the wrong way has Open and Close reversed at the keypad or drive block.

    Check: Keypad Close and Open move the drapery the right way; if not, exchange the keypad Open and Close wires.
