recognize the need to exit the bath, (3) unawareness of
impendinghazard,(4) fetaldamageinpregnantwomen,
(5) physical inability to exit the bath, and (6)
unconsciousness resulting in the danger of drowning.

base.
Slip the top of an apron up into the channel groove. Tilt
the apron inward. Align the bottom of the apron with the
pan base. The apron should align with both the bath rim
and the edges of the apron columns, and with the

Begin at one end, and peel back a few inches of the
paper backing from the kick strip.
Align the end of the kick strip to the finish wall and the
bottom of the whirlpool base. Lightly press the kick strip
to the whirlpool base.
Peeling back a few inches of paper backing at a time,
continue aligning and pressing the kick strip to the
whirlpool base.
After the kick strip is completely applied, go over the
entire length with firm pressure to secure the kick strip
to whirlpool base.

16. CLEAN-UP AFTER INSTALLATION
When cleaning up after installation, do not use
abrasive cleansers as they may scratch and dull the
bath surface. Use warm water and a liquid detergent to
clean the surface.
Stubborn stains, paint, or tar can be removed with
turpentine or paint thinner. Do not allow cleaners
containing petroleum distillates to remain in
contact with whirlpool surfaces for long periods of
time. Plaster can be removed by scraping with a wood
edge. Do not use metal scrapers, wire brushes, or other
metal tools. A powder-type detergent may be used on a
