Framing and SupportThe drain/overflow of the bath extends below the bottom of the bath. Note that this requires a cutout in the floor.The floor structure beneath the bath must be able to support a total weight of bath, water, and bather.Refer to the table under total weight for your model. The unit must be supported from the bottom of the bath andnot from the bath rim or tile flange. If the subfloor is level, no other preparation is necessary. You can proceed toinstall the bath. If the subfloor is not level, you MUST level the entire surface prior to installing the bath. The use ofmaterials that shim or provide a level installation are allowed provided the method used will insure a level bath thatis supported from the bottom. Materials that may be used are a floor leveling compound, mortar, plaster or minimalexpansion structural foam having a density of a minimum of 5 lbs./cubic ft.; however the bath must remain level inorder for it to drain properly and the foam feet must make full contact with the leveling material. Both sides of a jointor splice of subfloor should be level to each other. When attaching baths with flanges to stud wall, use shims tofill any gaps between the bath flange and studs.The rim of the bath is not designed to support weight. If finish material is to overlap or contact the bath, the addedweight must be fully self-supporting.The protective film liner inside the bath is used to prevent damage to the finish from shoes, tools, etc.during installation. Before installation, remove liner to inspect for any defects, reapply and do not removeuntil final cleanup.Important: If a skirt is to be used, it must be installed at the time of unit installation – refer to skirtinstallation instructions. Install optional trim parts when all installation has been completed.FLUSH TO WALL SEMI-SUNKEN OPTIONAL TILE FLANGE KITTILE1" X 4" (NOT FOR SUPPORT)MORTAR OR ADHESIVEFLASHINGSEALANTSUB-FLOORFINISHINGMATERIALBATH RIMNAILORSCREWCEMENTBOARDSTUDWALLSILICONESEALANTPLASTERFILLERFLANGEFLASHINGSEALANTMORTAR OR ADHESIVE TILEMORTARTYPICAL INSTALLATIONS1" X 4" (NOT FOR SUPPORT) 1" X 4" (NOTFOR SUPPORT)TYPICAL FLANGE MOUNTING DETAILSTUDTILEADHESIVETILECEMENTBOARDFLANGE1/8" GAPSTUDFLANGESHIM IFNECESSARYTO FILL GAPSBETWEENSTUDAND FLANGECAULKINGATTACH WITHSCREWSPROVIDEDINSTALLATION5Jacuzzi Whirlpool Bath© U961000F 12/04
