3 WALL BASE INSTALLATION
The floor structure beneath the unit must be able to
support a total weight of the unit and bather. Refer
to the table under total weight.
STEP 1
Provide an opening in the subfloor no less than 5" x 5"
square. This opening should be located on the center
lines of the shower base drain hole (See Product Chart).
The opening is to accommodate a 2" waste pipe. The
waste pipe should be 1/4" to 1/2" above the surface of
the subfloor.
STEP 3
If the subfloor is level, no other preparation is neces-
sary. You can proceed to install the shower base. If the
subfloor is not level, level shower base by spreading
floor leveling compound, mortar, plaster or minimal
expansion structural foam with a minimum density of 5
lbs./cubic feet EVENLY over ENTIRE area where base
will be installed. The compound used MUST make
contact with the entire bottom surface of the base. Both
sides of a joint or splice of subfloor should be level to
each other. Level and support waste pipe cutout area
greater than 5" x 5". The base is NOT to be supported
by the tile flange.
STEP 2
Remove the stainless steel strainer from the drain
assembly. Disassemble the locknut and two gaskets
from the back of the drain assembly. Apply a 1/4" bead
of caulking (silicone) to the drain hole and insert the drain
assembly. Replace the rubber washer, fiber washer,
and lock nut in that order. Hand tighten the locknut.
Remove excess sealant from finished side.
Apply a lubricant (common household liquid soap
works well) to the inside of the rubber seal of the drain
assembly.

CAUTION: A nonflammable protective barrier must
be placed between soldering work and base unit to
prevent damage to the base.
When connecting the supply lines, the toe plate can be
notched to accommodate the pipes.
The pipe under the base can be cut to length. To do so,
remove the pipe clamps under the base, cut the pipe and
