INSTALLATION REQUIREMENTS
20
Heater Installation (if installed). Heaters shall
be installed in accordance with the authority
having jurisdiction and in accordance with the
manufacturer’s specifications.
Backflow. No direct mechanical connection
shall be made between the potable water
supply and spa, sanitizing equipment or
the system of piping for the spa, unless it
is protected against backflow and back-
siphonage in a manner approved by the
authority having jurisdiction or through an
air gap, meeting the latest ANSI A112.1.2
(R1991) standard.
Water temperature. Where installed, the
heater manufacture shall provide instructions
stating that the temperature of the in-coming
make-up water shall not exceed 104°F (40°C)
as recommended in ANSI/UL 1563, Standard
for Electric Hot Tubs, Spas and Associated
Equipment.
Deck Depth Markers. Depth markers shall
be positioned on the deck within 18 inches
(45.72 cm) of the waterline and shall be
positioned to be read while standing on the
deck facing the water.
Depth markers in or on the deck surfaces
shall be slip-resisting.
Clock. All public facilities shall have a clock
which is visible from the spa.
The spa operator shall be provided with
an accurate thermometer ± 1˚F (±0.56 ˚C)
tolerance and shall periodically check to
ensure that the maximum temperature does
not exceed 104˚F (40˚C).
A means to determine the spa temperature
with a ± 1˚F (± 0.56 ˚C) tolerance shall be
provided to the user.
Flowmeter. An accurate flowmeter shall be
installed after the circulation, filtration, and
heating equipment, before the chemical feed
system (see “Return Plumbing” drawings).
Spa Use Sign. Install supplied warning safety
sign in a location clearly visible from spa.
Supplemental water sanitation and treatment.
The applicable requirements of NSF/ANSI 50
shall apply to any equipment installed for use
in treatment of spa water, including:
• Ozone systems, including NSF-50 Sections
11 and 12
• UV light systems, including NSF-50 Sections
11 and 13
• Copper and silver ion generators, including
NSF-50 Sections 11 and 16.
Entry/Exit Handrail. An entry/exit handrail shall
be provided to allow for safe entry and exit
of the spa. This handrail shall be designed
and installed in accordance with the local
authority having jurisdiction. When installing
and orienting the handrail, care must be
taken to assure that the handrail works in
conjunction with existing handrail(s) pre
installed on the shell from the factory.
The product is equipped with some handrails
that will serve the purpose below the level
of the spa. It is imperative that Entry/
Exit Handrails be considered with respect
to all local codes prior to the purchase of
the spa and construction of the project.
Requirements vary drastically from local to
local so a little research regarding handrails
prior to kicking off the project will go a
long way in getting permits, etc. approved
during the construction process. It should
be noted that the likelihood of designing,
and purchasing different, and even possibly
custom handrails to complete this project is
high, and can delay the project if not properly
considered during the design stage of the
project. Consult your local authority having
jurisdiction, Master Spas Customer Service,
and/or a handrail manufacturer for any
questions you may have.
Barrier. A listed ASTM F1346 lockable
safety cover shall be the minimum barrier
requirement. Check all local and state
codes provided by the local authority having
jurisdiction for additional or more restrictive
requirements. Should the code(s) have
a more restrictive requirement, the more
restrictive requirement shall be the minimum
installation requirement.
Lift Chair. An ADA compliant lift chair
shall be installed in accordance with the
manufacturers recommendations and
shall comply with all ADA regulations. See
“Overall Design Information” section for
recommendations.
