uick Check List for Installation

Decide if you need to recess the unit into the floor for best wheel chair access and if so,cut out the flooring.Mark where the perimeter of the new unit will be, then mark and cut 1 inch beyond that.Check framing pocket for size, plumb (use a plumb bob) and level and adjust by cutting orshimming as needed. Our (optional) Flange Trim Kit can help here.Add studs or blocks to the side wall corner studs for attaching the vertical back wall flanges.Not needed on these models : 4LES5430B17T, 3EWS6030, 5LDS6030B17T,5LES6048B1B and 5LES7248B1B.Add studs or blocks to the side wall front for anchoring the flanges.Prepare the drain hole in the floor and the drain fitting.Prepare and cut holes for the plumbing.For Barrier Free units with Low Profile bottom, see"Installation Instructions for Showers with Low Profile Bottoms".Install the Pan with the epoxy anchor and fasten to the studs.

.Install the Backwall and attach at the top.

.Dry-fit the side walls and eliminate any corner gap.See "Instructions to eliminate the gap between a bowed backwall and the side walls"

.Complete installation and caulk all joints.

.Install (optional ) Flange Trim Kit and other accessories.Following are more detailed instructions.

INSTALLATION1. Mark and cut out the drywall to fit the shower as follows:1-1/2" above the level where the highest point of the shower will beSee Figure 1A

Mark and cut out the drywall in front to fit the shower as follows:1-1/2" past where the farthest point of the shower will beSee Figure 1B

2. Install the studs that will provide support for thefront nailing flanges and the drywall as follows:

Slip two studs in the space in front of the most forward stud SIDEWAYS and screw it to this stud.See Figure 2 A and B.Now screw the drywall to this stud

If you need to keep the curb as low as possible formaximum accessibilty and want to install the pan onthe floor joists, proceed as follows:

If the joists run perpendicular to the shower curb, run2x4 between and flush with the top of the joists.This is to provide support for the back of the pan andallows shimming. See Figure 3C.

If the joists run parallel to the shower curb and thereis no joist for the curb or rear of the pan to rest on,install blocks against the joists, then install plywoodflush with the joists. See Figure 3D.

6. If you need to install a new diverter mixing valveon the back wall, pre-plan the lay-out with the valve,glide bar and grab bar positions in mind.Shut off the water supply and cut the hot and cold

lines between 2" and 4" above the bottom plate.Route these lines through the studs (except for2 ea. 45 degree elbows in front of the corner studs)toward the new valve location on the back wall.See Figure 6.

If the plumbing is kept at the original plumbing wall, just reposition the valve (be sure to plug the port tothe tub spout that is now unnecessary) and theshower outlet.If you are installing the valve on the back wall,run the pipes about 8" above the bottom plate,but do not commit to a final position of the valveand fittings until you can line these up with the holesin the wall panels.

7. Set the pan in the opening, carefully slipping thedrain fitting over the drain pipe. (No Figure 7)

8. Level the pan in all directions. See Figure 8.

11. Drill the holes for the plumbing, based on thepre-planning discussed in Step 6. See Figure 11.

. Hang a plumb bob FLUSH with the back side ofhe drywall from temporary screws. See Figure 9.

10. If the studs are leaning in, shim between the pan andhe framing and check that the pan is still level before screwingt to the studs.

f the studs are leaning out, you can either:A. Cut into the studs orB. Shim out.The optional Flange Trim Kit is a good way to helpransistion to the drywall.

Keep the screws in the pan flanges close to the edge of thelange so the wall panel will not hang up on these screws.

See Figure 10 A and 10 B.

12. Screw the flanges to the studs, anglingslightlydow ward to help snug the walls to the pan.Shim as needed.See Figure 12 .

13. Shim behind all wall panels as needed and screwthe flange to the studs at 8" intervals.See Figure 13.

14.-Caulk all joints by cutting a small, angled hole in the tipof the tube of silicone and forcing it into the joint.

-Install any grab bar, seat, glide bar or other options inthe plywood backing that is integral in the shower walls.See specific installation instructions .

-Install drywall over the nailing falnges or as a fasteroption use our Flange Trim Kit FTK-R-25-3.

-Dirty scuffmarks can be wiped off with paint thinner oracetone and deeper scratches can be sanded out with400-, then 600 wet and dry, followed by a hand buff with

automotive buffing compound.
