INSTALLATION NOTES
Unpack your unit carefully and inspect for freight damage. Lay out and identify all parts using the instruction sheets as a reference. Before discarding the carton, check for small hardware bags that tend
to fall to the bottom of the box. If any parts are damaged or missing, refer to the descriptions noted in
the instructions when contacting your dealer for replacements.
Handle glazed panels carefully and protect the edges. Safety tempered glass is very resistant to breakage, but the sharp corners of the panels can damage tile and floor coverings.
Please wear safety glasses whenever drilling or cutting. When drilling holes in ceramic tile or marble, use
a center punch and hammer to carefully break the surface glaze so the drill can start without skidding.
To install your A
LUMAX Bath Enclosure you will need the following: tape measure, level, #2 Phillips
screwdriver, flat screwdriver, drill, 1/8", 7/64" and 3/16" drill bits, hacksaw, pencil, and caulking (clear
silicone recommended). Optional tools include a miter box for cutting parts to length, files, center
punch, and masking tape.
NOTE: Before beginning installation, check the tub rim for level and both walls for plumb. If either are
off more than 1/4" to 3/8", you may want to contact your dealer for tapered fillers which can be used
to level the tub track or plumb the wall jambs.

1
Measure the wall-to-wall opening at the center
of the tub rim. Cut the tub track [A] 1/16” short of this
dimension. An inexpensive miter box (available at your
local hardware store) will help you get clean, square cuts.
If the vinyl silencer [R] is separate from the tub track [A],
slide the vinyl silencer into the slot in the tub track and
trim excess silencer material.
Position the tub track [A] in the center of the tub rim with
the tall leg to the exterior. It may be necessary to file a
radius on the ends of the tub track [A] and wall jambs
[B] to match the corners of the enclosure.
Press both wall jambs [B] into position over the tub track
[A]. Masking tape can be used to temporarily hold the
parts in place.
2
Use a level to plumb both wall jambs [B], then mark
the pre-drilled hole locations on the wall. Lightly mark
along both sides of the tub track [A] with a pencil, and
then remove all parts.
For tile or marble walls, drill six 3/16” diameter holes and
insert the plastic wall anchors [C]. Attachment to fiberglass
or acrylic units can be made in 2 ways. If reinforcement
is built into the unit, drill six 1/8” holes and install the
mounting screws directly into the reinforcement. If the
walls are not reinforced, drill six 3/16” holes and install
plastic wall anchors [C] or toggle bolts (toggle bolts not
supplied by Alumax).
CAUTION: The track [A] should never be screwed to
the tub. This will damage the tub and cause leaking.
3
Before replacing the tub track [A], force a small
downward bow into the extrusion. This will ensure the
tub track [A] fits tight to the tub. Run 2 beads of caulk
inside the penciled marks on the tub rim. Place the tub
track [A] in the exact position marked in step #2 and
seat it firmly in the caulking.
NOTE: Improper caulking will result in leaks.

Replace one wall jamb [B] and attach to the wall
with a #8 x 1 1/2” truss head screw [D] through the
middle hole. Place a #8 x 1 1/2” truss head screw [D]
through one of the top jamb bumpers [E] and attach
through the top hole.
For proper orientation of the bottom jamb bumper [F]
refer to the detail, and note that the one on the wall jamb
closest to the shower head, the lip is turned to the interior
of the enclosure, and that the other one is turned to the
exterior. Attach the bottom jamb bumper [F] with a #8
x 1 1/2” truss head screw [D].
NOTE: Do not over tighten the screws.
5
This Bath enclosure is equipped with safety teelock wall jambs. When properly installed, the header
is permanently locked to the wall jambs and cannot be
accidentally dislodged.
Measure the wall-to-wall opening at the top of the wall
jambs [B] and cut the header [G] 1/16” short of this
dimension. Check the header [G] for fit.
Slide the safety tee-lock of the un-mounted wall jamb [B]
into the end of the header [G]. The header is reversible
so that either face may be turned to the exterior of the
unit. Holding the header [G] at an angle, engage the
other end into the safety tee-lock of the mounted wall
jamb. Pivot the header [G] into place, slide the loose
wall jamb [B] to the wall and press into position over
the tub track [A]. Mount the wall jamb [B] to the wall
as described in step #4, taking note of the orientation
of the bottom jamb bumper [F].
6
NOTE: Obscure glass doors should be installed
with the rough surface of the glass to the exterior of the
unit. Deco or etched glass doors should be installed
with the patterned surface to the interior.
On doors with obscure or etched glass there is an interior
and exterior glazed door panel [H] as determined by the
position of the top bearing fin. Door panels with clear
glass are interchangeable.
Attach the 4 nylon roller bearings [I] to the door panels as
shown, using #8-32 x 3/8 hex head screws [J] centered
in the outside slots in the top bearing fins.

7
Lift the interior glazed panel (with the rough surface
closest to the fin) into position with the rollers engaging
the roller slot in the header [G].
Repeat for the exterior panel (rough surface away from
the fin).
If the door panels [H] are not parallel to the wall jams,
remove them and adjust the bearings up or down to
compensate.
8
Before finishing the installation it is necessary to
determine the proper closed position of the glazed door
panels [H]. For maximum water proofing, place the interior panel closest to the shower head as shown in the
detail.
9
On the interior panel, loosely install a towel bar
bracket [M] to the vertical rail that is to the middle of
the unit, in the closed position, using a special 1/4-20
x 1” phil FH screw [K]. Place a towel bar [L] into the
mounted towel bar bracket [M] and install the remaining
towel bar bracket onto the other side of the panel using
the 1 3/4” tapered pin [O]. Tighten both fasteners and
the set screws that hold the towel bar. Place a finger
pull [N] over the tapered pin [O], with the set screw on
the bottom and tighten the set screw. Install the o-rings
[S] onto the finger pull if they are not already in place.
Repeat for the exterior panel.

Locate the bottom guide [P] in the middle of the
tub track [A]. With a 7/64” bit, drill two holes into the
v-groove through the mounting holes in the guide. Install
the bottom guide with two #6 x 3/8” truss head screws
[Q] through the drilled holes as shown.
11
Caulk both ends of the tub track [A] where it
meets the wall jambs [B] and the interior edge of the
wall jambs as shown. Run a bead of caulking along the
interior of the tub track.
NOTE: We recommend that you let the caulk cure for 24
hours before you use your new enclosure.
