The Inspection. The spa owner or builder shall
notify the authority having jurisdiction at
specific, predetermined stages of construction
and at the time of completion of the spa to
permit inspections as may be required.
Installation. The spa and its equipment
shall be supported to prevent damage from
misalignment, settling, etc., and located in
such a manner to allow access for inspection,
servicing, removal and repair of component
parts.
Direct sunlight. The spa shall be shall be
covered as a means to protect the spa when
not in use from direct sunlight exposure. All
exposed plumbing should be painted with a
UV stable formulation to prevent UV damage
to exposed plumbing. Usually black paint will
satisfy this requirement.
Circulation system piping. Circulation system
piping, other than that integrally included in
the manufacture of the spa, shall be subject
to an induced static hydraulic pressure test
(sealed system) at 25 pounds per square inch
(1.7577035 kg/sq. cm) for 30 minutes. This
test shall be performed before the deck is
poured, and the pressure shall be maintained
throughout the deck pour.
Valves installed in or under any deck(s)
shall provide a minimum of 9 inches (22.86
cm) diameter access cover and valve pit to
facilitate servicing.
Hose bibb. A hose bibb with a vacuum
breaker shall be provided for washing down
the entire deck area.
Circulation system components. Components
which require servicing shall be accessible for
inspection and repair, and shall be installed
in accordance with the manufacturer’s
specifications.
Spa equipment shall be properly supported
to prevent damage from misalignment,
settlement, operational movement, etc.
The equipment shall be mounted so as to
minimize the potential for the accumulation
of debris and moisture, following
manufacturer’s specifications.
Equipment shall be designed and fabricated
to drain the spa water from the equipment,
together with the exposed face piping, by
removal of drain plugs and by manipulating
valves or by other methods.
In addition to programmed filtration times
(if installed), recirculation equipment shall
be in operation during the hours the spa is
accessible for use.
All filter elements, media and other
components which require servicing shall be
accessible for inspection, removal and repair,
and shall be installed in accordance with the
filter manufacturer’s instructions.
Pumps shall be accessible for inspection,
service and maintenance.
Spas shall have a circulation, filtration, and
treatment system consisting of equipment
such as pumps, piping, fittings, return
inlets, suction outlets, filters, skimmers and
other necessary components that promote
circulation of water throughout the spa. The
circulation system shall be capable of:
• Producing a circulation turnover rate of
the total water volume of the spa through
the filtration system within 30 minutes or
more quickly as determined by the local
regulatory authority having jurisdiction.
• Not having a standby mode to reduce
circulation and filtration rate below
the minimum required by public health
authority having jurisdiction.
Grounding and bonding. Grounding and
bonding required in a public spa shall comply
with the requirements of the National
Electrical Code (NEC) ®, ANSI/UL 1563
Standard for Electric Hot Tubs, Spas and
Associated Equipment and the authority
having jurisdiction.
See “Typical Work Involved for Installation
of Master Spas Spa”, “Electrical Contractor
Installation” section for specific requirements.
IMPORTANT NOTE. Requirements for
grounding and bonding are particularly
important and shall be adhered to.
Maintenance Disconnect Means. Disconnecting
means shall be accessible, located within
sight of the electrical equipment and shall be
located at least 5 feet (1.524 m) horizontally
from the inside walls of the spa.
Emergency Shut-off Switch. A clearly labeled
emergency shutoff or control switch for the
purpose of stopping the motor(s) that provide
power to the re-circulation system and jet
system shall be installed readily accessible to
the users and at least 5 feet (1.524 m) away,
adjacent to and within sight of the spa.
