Attention New Spa Owner!
Congratulations on the purchase of your new Sundance®680 Series
spa! The following is a list of automated functions and maintenance
recommendations for your new spa. Automated functions have been
listed below in an attempt to suppress any operational concerns you may
have during startup and the rst 24 hours of ownership! Maintenance
recommendations are listed in an attempt to stress their importance in
protecting your new spa.
Automated Operations
Approximately two minutes after power is applied to the spa, the rst
ltration/heating cycle turns on pump 1. In Hartford and Hawthorne models,
an automatic ve minute “blow-out” function also activates pump 2 for a
period of ve minutes to ush all lines. Then, after ve minutes, pump 2
turns off and pump 1 continues to operate for the duration of the cycle.
Note: this function only occurs during the rst ltration/heating cycle each
day.
Maintain Healthy Spa Water
Always maintain your spa’s water chemistry within the following parameters
as dened by the Association of Pool And Spa Professionals/USA:
pH 7.4-7.6
Free Chlorine 3.0-4.0 ppm
Free Bromine 2.0-4.0 ppm
Total Alkalinity 100-120 ppm
Calcium Hardness 150-250 ppm
Always maintain your spa lter as outlined below to ensure healthy spa
water. Refer to pages 34-35 for additional information.
Required Filter Maintenance
Your new spa is equipped with an advanced water ltration system that
provides unsurpassed water quality! To ensure maximum water quality at all
times, you should clean and reuse both lter cartridges every month or as
needed. See page 30 for detailed lter cleaning/replacement instructions.
Required Water Maintenance
You should replace the spa’s water every 3 months. The frequency
depends on a number of variables including frequency of use, number of
users, and attention paid to water quality maintenance. You will know it
is time for a change when you cannot control sudsing and/or you can no
longer get the normal feel or sparkle to the water, even though the key
water balance measurements are all within the proper parameters. See
pages 34-35 for additional information.

1.0 Important Spa Owner Information
Your Sundance®680 Series spa is constructed to the highest standards
and is capable of providing many years of trouble-free use. However, be-
cause heat retentive materials are utilized to insulate the spa for efcient
operation, an uncovered spa surface and wall ttings directly exposed
to sunlight and high temperatures for an extended period are subject
to permanent damage or discoloration. Damage caused by exposing
the spa to this abuse is not covered under warranty. We recommend
that you always keep the spa full of water when it is exposed to direct
sunlight and that you keep the Sundance premium insulating cover in
place at all times when the spa is not in use. Read and carefully follow
the requirements for your spa’s support base found in Section 4.0 titled,
“Choosing a Location” (page 7).

turer.
8. ELECTRICAL SUPPLY: The electrical supply for this product must
include a suitably rated switch or circuit breaker to open all un-
grounded supply conductors to comply with Section 422-20 of the
National Electrical Code/USA, ANSI/NFPA 70. The disconnect must
be readily accessible and visible to the spa occupant but installed at
least 5 feet (1.5m) from the spa water.
9. WARNING: To Reduce the Risk of Injury:
10. The water in a spa should never exceed 104°F (40°C). Water tem-
peratures between 100°F (38°C) and 104°F (40°C) are considered
safe for a healthy adult. Lower water temperatures are recommend-
ed for young children and when spa use exceeds 10 minutes.
11. Since excessive water temperatures have a high potential for caus-
ing fetal damage during the early months of pregnancy, pregnant
or possibly pregnant women should limit spa water temperatures to
100°F (38°C). If pregnant, please consult your physician before us-
ing a spa.
12. Before entering the spa, the user should measure the water tem-
perature with an accurate thermometer since the tolerance of water
temperature-regulating devices may vary as much as +/- 5°F (2°C).
13. The use of alcohol, drugs, or medication before or during spa use
may lead to unconsciousness with the possibility of drowning.
14. Persons suffering from obesity or a medical history of heart disease,
low or high blood pressure, circulatory system problems, diabetes,
infectious diseases or immune deciency syndromes should consult
a physician before using a spa. If you experience breathing difcul-
ties in association with using or operating your spa, discontinue use
and consult your physician.
15. Persons using medication should consult a physician before using
a spa since some medication may induce drowsiness, while other
medication may affect heart rate, blood pressure, and circulation.
16. Always shower before and after using your spa. To reduce the pos-
sibility of contracting a waterborne illness, always maintain water
chemistry within the parameters listed on the inside cover of this
manual. If you or other bathers experience such a condition, discon-
tinue use and seek medical attention.

When using this electrical equipment, basic safety precautions should
always be followed, including the following:
1. READ AND FOLLOW ALL INSTRUCTIONS.
2. A green colored terminal or a terminal marked G, Gr, Ground,
Grounding or the symbol* is located inside the supply terminal box
or compartment. To reduce the risk of electric shock, this terminal
must be connected to the grounding means provided in the electric
supply service panel with a continuous copper wire equivalent in
size to the circuit conductors that supply this equipment (*IEC Publi-
cation 417, Symbol 5019).
3. At least two lugs marked “Bonding Lugs” are provided on the exter-
nal surface or on the inside of the supply terminal box/compartment.
To reduce the risk of electric shock, connect the local common bond-
ing grid in the area of the spa to these terminals with an insulated or
bare copper conductor not smaller than No. 6 AWG (10mm²).
4. All eld-installed metal components such as rails, ladders, drains or
other similar hardware within 10 feet (3m) of the spa shall be bonded
to the equipment grounding buss with copper conductors not smaller
than No. 6 AWG (10mm²).
5. SAVE THESE INSTRUCTIONS
WARNING: Children should not use spas without adult supervision.
WARNING: Do not use spas unless all suction guards are installed to
prevent body and hair entrapment.
WARNING: People with infectious diseases should not use a spa.
WARNING: To avoid injury, exercise care when entering or exiting the
spa.
WARNING: Do not use drugs or alcohol before or during the use of a
spa to avoid unconsciousness and possible drowning.
WARNING: Pregnant or possibly pregnant women should consult a
physician before using a spa.

Page 5
WARNING: Water temperature in excess of 38°C (104°F) may be injuri-
ous to your health.
WARNING: Before entering the spa, measure the water temperature
with an accurate thermometer.
WARNING: Do not use a spa immediately following strenuous exercise.
WARNING: Prolonged immersion in a spa may be injurious to your
health.
WARNING: Do not permit electric appliances (such as lights, radios,
telephones, televisions, etc.) within 5 feet (1.5m) of this spa unless fac-
tory installed.
CAUTION: Maintain water chemistry in accordance with manufacturer’s
instructions.
WARNING: The use of alcohol or drugs can greatly increase the risk of
fatal hyperthermia in spas.
3.2 Hyperthermia
Prolonged immersion in hot water may induce hyperthermia. A descrip-
tion of the causes, symptoms, and effects of hyperthermia are as fol-
lows:
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,
and an increase in the internal temperature of the body. The effects of
hyperthermia include:
A Unawareness of impending hazard;
B. Failure to perceive heat;
C. Failure to recognize the need to exit spa;
D. Physical inability to exit spa;
E. Fetal damage in pregnant women; and
F. Unconsciousness and danger of drowning.

Page 6
3.3 Cautions
1. Persons suffering from heart disease, diabetes, high or low blood
pressure, and any condition requiring medical treatment, pregnant
women, the elderly, or infants should consult with a physician before
using a spa.
2. The Consumer Products Safety Commission/USA has stated that
the water temperature in a spa should not exceed 104°F (40°C).
Immersion in water in excess of 104°F (40°C) can be hazardous to
your health.
3. Observe a reasonable time limit when using the spa. Long expo-
sures at higher temperatures can cause high body temperature.
Symptoms may include dizziness, nausea, fainting, drowsiness, and
reduced awareness. These effects could possibly result in drowning.
4. Do not use the spa under the inuence of alcohol, narcotics, or other
drugs. Use of the spa under these conditions may lead to serious
consequences.
5. Always test the spa water temperature before entering the spa. En-
ter and exit the spa slowly. Wet surfaces can be very slippery.
6. Never bring any electrical appliances into or near the spa. Never
operate any electrical appliances from inside the spa or when you
are wet unless such appliances are built-in by the manufacturer.
7. Proper chemical maintenance of spa water is necessary to maintain
safe water and prevent possible damage to spa components.
8. Use the straps and clip tie downs to secure the cover when not in
use. This will help to discourage unsupervised children from enter-
ing the spa and keep the spa cover secure in high-wind conditions.
There is no representation that the cover, clip tie-downs, or actual
locks will prevent access to the spa.
3.4 General Electrical Safety Instructions
Your new Sundance® spa is equipped with a “state-of-the-art” equipment
system. It contains the most advanced safety and self-protective equip-
ment in the industry. Nonetheless, this spa must be installed properly to
ensure dependable usage. Please contact your local Sundance dealer
or local building department should you have any questions regarding
your installation.
Proper grounding is extremely important. Sundance spas are equipped
with a current collector system. A pressure wire connector is provided
on the surface of the control box, located outside the equipment door
(Figure B, page 14) to permit connection of a bonding wire between
this point and any ground metal equipment, metal water pipe or conduit

Page 7
within 5 feet (1.5m) of the spa, or copper clad grounding rod buried
within 5 feet (1.5m) of the spa. Bonding wire must be at least No. 8 AWG
(8.4mm²) solid copper wire. This is a most important safety assurance
feature.
Before installing your spa, check with your local building department to
insure installation conforms to local building codes.
120/240 Volt Denali And Tacoma Convertible Models
A spa connected to a 120 VAC electrical service must be located close
enough to a grounded, grounding-type electrical outlet so that the in-
cluded 10 foot (3m) power cord can be plugged directly into it. DO NOT
USE AN EXTENSION CORD as this could cause damage to the spa’s
equipment due to insufcient voltage. The power supplied to this spa
must be a dedicated circuit with no other appliances or lights sharing the
power provided by the circuit.
4.0 Choosing A Location
IMPORTANT: Because of the combined weight of the spa, water
and users, it is extremely important that the base upon which the
spa rests be smooth, at, level and capable of uniformly supporting
this weight, without shifting or settling, for the entire time the spa
is in place. If the spa is placed on a surface which does not meet
these requirements, damage to the skirt and/or the spa shell may
result. Damage caused by improper support is not covered under
warranty. It is the responsibility of the spa owner to assure the
integrity of the support over time. We recommend a poured, rein-
forced concrete slab with a minimum thickness of 4 inches (10cm).
Wood decking is also acceptable provided it is constructed so that
it meets the requirements outlined above.
The spa must be installed in such a manner as to provide drainage away
from it. Placing the spa 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 panels and access to the jets components, especially on the
side with the equipment bay.

Page 8
4.1 Outdoor Location
In selecting the ideal outdoor location for your spa, we suggest that you
take into consideration the following:
• The proximity to changing area and shelter (especially in regions
subject to cold weather).
• The pathway to and from your spa (this should be free of debris so
that dirt and leaves are not easily tracked into the spa).
• The closeness to trees and shrubbery (remember that leaves and
birds could create extra work in keeping the spa clean).
• 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 spa under an unguttered roof overhang since run-off water
will shorten the life expectancy of the spa cover.
4.2 Indoor Location
For indoor installations many factors need to be considered before
installing a spa indoors:
• PROPERFOUNDATION: Consult a Structural Engineer when con-
sidering a foundation that will adequately support the spa the entire
time it is in place. Proper support is critical especially if the spa is to
rest on a second story or higher. For spas that are to rest on balco-
nies, roofs or other platforms not specically tied into the main struc-
tural 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 spa rests on has adequate drainage and
can handle draining of the entire contents of the spa. Be sure to
make provisions for ceilings or any other structures that may be
below the spas installation. Areas around your spa 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.
• 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 spa is in use
considerable amounts of moisture will escape potentially causing

Page 9
mold and mildew, over time this can damage certain surfaces and or
surroundings.
• SUFFICIENTACCESS. In the unlikely event that you should ever
need to access or gain entry to any portion of the spa for servicing,
it is highly recommended that you plan your indoor installation to
provide full access to the entire spa.
• WARRANTY. Damage caused by not following these guidelines or
any improper installation not in accordance with local codes or au-
thorities is not covered under the spas warranty. Please consult your
local state or city building ordinances.
WARNING: In addition to maintenance of lters and water
chemistry, proper ventilation is recommended to reduce the
risk of exposure to viruses and bacteria that could be pres-
ent in the air or water. Consult a licensed architect or building
contractor to determine your specic needs if installing your
spa indoors.

5.0 Power Requirements
Sundance® spas are designed to provide optimum performance and ex-
ibility of use when connected to the maximum electrical service listed on
pages 10-12. If you prefer, your dealer can perform a minor circuit board
modication to allow your spa to accept an electrical service other than
the factory setting (turn page for details). Note: Refer to pages 40-45 for
circuit board conguration details or contact your authorized Sundance
dealer.
