overtighten to the point that causes ange breakage.
18. Before installing the walls, conrm the ledges
where the walls sit are level. Check with a long
level as shown in Figure 16. If there is an out of level
condition, remove screws and adjust as required.
19. Before the adhesive cures, conrm the oor slope to
the drain has been maintained. To do this, use a 2 foot level
at various points around the drain to the adjacent wall to
check for draft. Make sure there is a downward slope to
the drain in all directions around the drain. Visually inspect
the oor to be sure there are no humps or dips that could
cause improper drainage.
See Figure 17A and 17B.
20. The next step will be to place the wall panels on the
pan. The back wall will be installed rst. If the water control
valve is in the back wall, carefully measure and mark the
location on the surface of the wall panel. If installing in a
shower with a two piece back wall, the valve probably will
be installed through the lower wall panel. Make certain the
valve does not conict with
the mounting ange or seam. Read the installation
instructions provided by the valve manufacturer. Before the
Trial t, carefully drill the valve hole (s) in the panel. When
drilled,dry Trial t the back wall panel (s) on the shower
pan to test the t.
Conrm the gap where the wall seats to the pan is 1/8” or
less. Make sure the seam for the two piece wall is also 1/8”
or less. Adjust the valve hole size and location if required.
Lift the wall panel with the valve hole away. Complete
the valve installation and connection to hot and cold
water supply at this time. Also complete shower supply
connection. Strap pipes to framing if required. This is the
last access to the plumbing before the wall is permanently
installed.
21. If all ts are good, proceed with the installation of the
the back wall. The installation procedures described in this
step apply for installation of one or two piece back walls.
Wipe clean the ledges on top of the pan. Apply a
continuous bead of 100% RTV silicone caulking along the
back ledge of the pan where the back wall will sit. The
bead should beplaced at the middle of the ledge, and be
3/8” wide. The bead should go completely around each
alignment pin.
There are slots on the underside of the wall. There are
alignment pins in the pan that will insert into the slots on
the bottom of the wall. See the detail in Figure 19.
The lower section of the back wall is the panel with a
single, molded soap dish. Lift this panel up and carefully
lower it onto the back ledge on the pan.
Push the wall panel down to seat it in the caulking.
Check the t for level and plumb.
Note to installer: There is a difference having the bubble
between the lines and a plumb wall. The wall must be
VERY plumb or a gap larger than 1/8” will be present
where the side walls mate the back wall. Use wood shims
or furring strips to ll any space between the back wall
ange and the studs.
Align the wall section where it meets the shower pan
so it is centered on the pan, and install wood shims or
furring strips if necessary.
Pre-drill the mounting anges. Attach the wall with screws
through the back wall ange into the framing. Be sure the
wall panel remain level and plumb. (For the 4836 4 piece,
this step will apply for the entire back wall as one piece).
22. For ve piece units, the next step is to place the top
section of the back wall. Clean the back ledge and apply
a continuous bead of 100% RTV silicone caulking along
the ledge of the back wall where the top part of the wall
will sit. The bead should be 3/8 wide and placed at the
middle of the ledge. It should go completely around each
alignment pin.
Lift the top back wall panel and set it on top of the lower
wall. Press the panel down to seat in the caulking. The top
and bottom wall panels must be level and plumb. Shim
if necessary. The seam between the panels should be no
more than 1/8”. Pre-drill holes and attach with screws
along the top back ange into the framing studs. Make
sure the two wall panels are in alignment and are level
and plumb. Place level or straight edge on both vertical
ange where the wall will mate to the back wall and
check to assure there are no gaps. (For the 4836 four
piece which has a single piece back wall panel, skip this
step).
23. Side wall installation. The side wall panels are slotted
on the bottom. The alignment pins in the pan will index
