2. Install the Module

- Remove the packaging from the front of the module.
- Install K-9459 Sonata Accessory Kit according the the instructions packed in the kit.
- Install the drain to the shower module according to the drain manufacturer's instructions.
- Use a drop cloth or similar material to protect the bottom surface of the module.
- Lay out and mark the location of the mixing valve, shower, and bath spout holes as required on the back
(unfinished) surface of the module wall. Drill 1/4" (6mm) pilot holes at the marked locations.
- From inside the module (finished surface), use a hole saw of the correct diameter to carefully drill the fitting
holes. Refer to the fitting manufacturer's instructions to determine the correct hole sizes.
- Clean the module to reduce the risk of surface damage.
- With help, carefully move the module into the recess.
- Be sure the bottom of the module is firmly supported against the floor. You may need to adjust some of the
framing. Use shims as necessary. However, no additional support is required. The module must be plumb and
level to ensure proper shower door installation.
- Use #6 large-head galvanized nails to fasten the nailing-in flanges to the studs. Use the pre-drilled holes in the
nailing-in flanges. Be careful to avoid damaging the module surface - shim between the nailing-in flange and the
studs to fill any gaps.
