Notes
Measure your actual product for roughing-in
details.
Install this product according to the installation
guide. Ensure that the bath, user interface,
amplifier, and transducers are functional before
completing the installation.
Control amplifier fits 16" (406 mm) center studs.
25' (7.6 m) cables are included.
Locate the bath within 24" (610 mm) of a
GFCI-protected 120 V, 15 A grounded electrical
outlet. A second grounded outlet within the wall
framing must be within 24" (610 mm) of the
planned control amplifier. One electrical service
may be used for the entire bath and related
electrical components.
Hot water supply should be 70% of capacity or
greater. Installations will vary.
