INSTALLATION AND FRAMING INSTRUCTIONS
The variety of installations possible for this whirlpool may require framing procedures other than those shown. Locate studs as needed. Ensure
roughing-in dimensions are proper, plumb and square. Provisions must be made in all installations for an access opening for servicing the pump
and controls. It is strongly recommended that an additional opening be provided for access to the drain components. The apron should not be used
as the primary access opening.

TYPICAL INSTALLATION
FIGURE 1
This bath must be supported along its entire bottom. Use mortar as bedding
material (do not use sand or foam). Apply enough mortar to support the complete
bottom of the bath. After the mortar has been poured, and before it sets, position
whirlpool or bath within recess until the rim is leveled against the leveling stringers (see
"Typical Recess Installation") shown below.
The rim of the bath must not support weight. Allow the mortar material to completely
harden before applying weight to the rim or bottom of the bath. Any finish material such
as tile or wall board must be self-supporting if it contacts the deck of the bath.
Replace whirlpool and re-shim the integral support feet, shimming the entire length of
the support feet. Secure the shims using construction adhesive, silicone, mortar or
equivalent materials. While not a necessity, the use of a foundation base consisting of
cement, mortar, or grout will help provide a solid and secure installation.
3. Install drain components to the whirlpool following the drain installation instructions. Before
replacing your whirlpool for final installation, be certain that an opening has been provided in
the sub-floor for the drain. See the roughing-in drawing and Table 1 for suggested opening
size (shadowed) and location dimensions. The 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 Table 1 under total weight for your model.
For Models: 2425L/V-LHO and 2425L/V-RHO;
For Models: 2645L/V, 2771L/V, 6060L/V, 7236L/V, 2422L/V and 2422LA/VA;
. Remove the whirlpool and attach a 1 x  stringer to the studs, with the top of the stringer touching the traced line.
The rim of the bath must not support weight.
1. Position the whirlpool into the installation opening and level the deck in both directions, shimming the integral support feet IF necessary.
Mark the final position of the underside of the deck by tracing a line on to the studs (see Figure 1).
