hyperthermia in spas. A description of the causes, symptoms, and effects
of hyperthermia are as follows:
Hyperthermia occurs when the internal temperature of the body reaches
a level several degrees above the normal body temperature of 98.6°F
(37°C). The symptoms of hyperthermia include drowsiness, lethargy
(fatigue), and an increase in the internal temperature of the body (feeling
of being too hot). The effects of hyperthermia include:
• Unawareness of impending hazard;
• Failure to perceive heat;
• Failure to recognize the need to exit hot tub;
• Physical inability to exit hot tub;
• Fetal damage in pregnant women; and
• Unconsciousness and danger of drowning.

4.0 Choosing a Location
IMPORTANT: Because of the combined weight of the hot tub,
water and users, it is extremely important that the base upon which
thehottubrestsbesmooth,at,levelandcapableofuniformly
supporting this weight, without shifting or settling, for the entire time
the hot tub is in place. If the hot tub is placed on a surface, which
does not meet these requirements, damage to the skirt and/or the
hot tub shell may result. Damage caused by improper support is
not covered under warranty. It is the responsibility of the hot tub
owner to assure the integrity of the support at all times. We recom-
mend a poured, reinforced concrete slab with a minimum thickness
of 4 inches (10 cm). Wood decking is also acceptable provided it is
constructed so that it meets the requirements outlined above.
WARNING:For spas that are to rest on balconies, roofs
orotherplatformsnotspecicallytiedintomainstructural
support, consult a professional Structural Engineer with expe-
rience in this type of application.
!
The hot tub must be installed in such a manner as to provide drainage
away from it. Placing the hot tub in a depression without provisions
forproperdrainagecouldallowrain,overowandothercasualwater
tooodtheequipmentandcreateawetconditioninwhichitwould
sitin.Forspaswhichwillberecessedintoaoorordeck,installso
as to permit access to the equipment, either from above or below, for
servicing. Make certain that there are no obstructions, which would
prevent removal of all side cabinet side panels and access to the jet
components, especially on the side with the equipment bay.
CAUTION: If the hot tub is indoors or located in an enclosed area,
proper ventilation should be discussed with an Engineer or authority
competent enough to understand the necessary provisions needed
to vent moist or heated air and air associated with chemical odors
outdoors. When the hot tub is in use considerable amounts of
moisture will escape potentially causing mold and mildew. This
can cause health risk. Over time, this can damage certain surfaces,
surroundings, and equipment.
4.1 Outdoor Location
In selecting the ideal outdoor location for your hot tub, we suggest that
you take into consideration:
• The proximity to changing area and shelter (especially in colder
weather).
• The pathway to and from your hot tub (this should be free of debris
so that dirt and leaves are not easily tracked into the hot tub).
• The closeness to trees and shrubbery (remember that leaves and
birds could create extra work in keeping the hot tub clean).
!

Page 10
BAY Collection
• A sheltered environment (less wind and weather exposure can result
in lowered operation and maintenance costs).
• The overall enhancement of your environment. It is preferable not
to place the hot tub under an unguttered roof overhang since run-off
water will shorten the life expectancy of the hot tub cover.
• For spas that are to rest on balconies, roofs or other platforms not
specicallytiedintomainstructuralsupport,consultaprofessional
Structural Engineer with experience in this type of application.
• In the unlikely event that you should ever need to access or
gain entry to any portion of the hot tub for servicing, it is highly
recommended that you plan your outdoor installation to provide full
access to the entire hot tub. Please take this into consideration when
placing the hot tub in a deck or enclosed by a surrounding.
• Considerlocatingyourhottubawayfromanyreectivesurfaceor
glass to prevent any damage to the synthetic skirt.
• Do not shim the hot tub. To ensure proper support the hot tub must
sitatontheintendedfoundation.
4.2 Indoor Location
For indoor installations many factors need to be considered before
installing a hot tub indoors.
WARNING: Inadditiontomaintenanceofltersandwater
chemistry, proper ventilation is recommended to reduce the
risk of contracting a waterborne illness (e.g. an infection, bac-
teria or virus) and/or respiratory ailments that could be present
in the air or water. Consult a licensed architect or building
contractortodetermineyourspecicneedsifinstallingyour
hot tub indoors.
!
• Proper Foundation: Consult a Structural Engineer when
considering a foundation that will adequately support the hot
tub the entire time it is in place. Proper support is critical especially
if the hot tub is to rest on a second story or higher. For spas that
aretorestonbalconies,roofsorotherplatformsnotspecicallytied
into the main structural support, you should consult a professional
Structural Engineer with experience in this type of application.
• Proper Drainage: It is extremely important to have in place
measures to sufciently handle excessive water spillage. Be
suretheooringinwhichthehottubrestsonhasadequatedrainage
and can handle the entire contents of the hot tub. Be sure to make
provisions for ceilings and other structures that may be below the
spas installation. Areas around your hot tub can become wet or
moistsoallooringandsubsequentfurniture,wallsandadjacent
structures should be able to withstand or resist water and moisture.

Page 11
BAY Collection
• Proper Ventilation: Proper ventilation should be discussed with
an Engineer or authority competent enough to understand the
necessary provisions needed to vent moist or heated air and
air associated with chemical odors outdoors. When the hot tub
is in use considerable amounts of moisture will escape, potentially
causing mold and mildew over time, which can damage certain
surfaces and/or surroundings.
• Sufcient Access: In the unlikely event that you should ever need
to access or gain entry to any portion of the hot tub for servicing, it is
highly recommended that you plan your indoor installation to provide
full access to the entire hot tub.
• Warranty: Damage caused by not following these guidelines or any
improper installation not in accordance to local codes or authorities is
not covered under the spas warranty. Please consult your local state
or city building ordinances.
