IMPORTANT ORDERING & INSTALLATION INFORMATION:
• Before ordering or installing, please consider future access to equipment.
• This tub comes with an integrated overflow with direct connect toe tap drain provided to
complete installation. Align tub drain with drain pipe rough-in.
• Add bedding compound to fully level and support bottom of tub. Tubs equipped with an
air bath or a pre-leveled foam base are designed to rest on the floor without bedding
compound, provided the floor is level. Overall tub height is increased by approx. 2-3" when
tub is equipped with any air bath package or when pre-leveled foam base or frame system is
ordered. Please measure tub on-site before building tub decking.
• Radiance placed on floor locations will affect placement of air jets.
• When ordering Microbubbles, system components will extend beyond the perimeter of tub.
• Suction and control locations may vary. If you are planning to use a glass enclosure, MTI must
be advised when ordering for possible relocation of controls.
• Measurements are +1/2” and are subject to change without notice. Specifications and
configurations are subject to change without notice. Measurements herein supersede all
others published prior to publication date shown below.
