Indoor Spa Installation Guidelines
Spa placement must take into consideration national, state and local building, electrical
and plumbing codes, local geotechnical conditions affecting the structure of the building,
indoor environmental conditions, etc. The surrounding floor surface must have
sufficient traction to prevent slips and falls when wet. It is recommended that a floor
drain and/or catch basin is present to remove water that accumulates in the area with a
capacity up to the total volume of the spa model. Since ambient humidity will rise due to
the spa, ample ventilation is required to prevent mold, mildew, rot, fungus, bacteria and
other conditions related to high humidity. Materials and components in the surrounding
area must be able to withstand elevated humidity levels. Some chemicals for use in
sanitation of the spa may corrode metals, or degrade other materials in the surrounding
area. A ventilation design incorporating suction, fresh air intake, cross ventilation and/or
dehumidifiers may be required and should be determined by an appropriately licensed
professional. Ensure ample room is provided for any required servicing and that
equipment access panels are not blocked.
Strong foundational support is vital,
particularly if a second story site is selected. The adequacy of the structural
support for a spa placed on a floor above ground level or an elevated surface
must be determined by a licensed structural engineer, architect or contractor
depending on local and state requirements. Have the spa deck installed by a
knowledgeable contractor to ensure proper support.
Electrical Wiring
WARNING: The spa must be wired by a certified electrician in accordance with
local codes and regulations, as well as with these instructions. Failure to do so
will terminate all warranties and invalidate the independent certification
company’s mark.
1. The South Seas Spa requires a 240 VAC dedicated system. The spa must be
hard wired to the power supply, with no plug-in connections, extension cords, or
sharing of service. For stationary appliances not fitted with means for
disconnection from the electrical supply mains having a contact separation in all
poles that provide full disconnection under Overvoltage Category III, the
disconnection must be incorporated in the fixed wiring of all supply circuits in
accordance with the applicable wiring rules.
2. The spa requires 6 (10 mm²) or 8 (8.4 mm²) AWG copper wire is used,
depending on the GFCI size.
Do Not Use Aluminum Wire
.
3. The power supply must have a suitable Ground Fault Circuit Interrupter (GFCI),
according to Section 422-20 of the National Electrical Code, ANSI/NFPA 70-
7987 or other national installation requirement with a residual current device
(RCD) having a trip current of not more than 30 mA. This could be used as the
shut-off switch, which must be installed in plain view of the spa. This electrical
