BurlingtonTM • DenaliTM • TacomaTM
6530-680, Rev. B

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 Burlington 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:
Always maintain your spa lter as outlined below to ensure healthy spa
water. Refer to page 29 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 the lter cartridge every month. See
page 25 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
page 29 for additional information.
pH 7.2 - 7.4
Free Chlorine 3-5 ppm
Free Bromine 4-6 ppm
Total Alkalinity 100-120 ppm

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,
because heat retentive materials are utilized to insulate the spa for effi-
cient operation, an uncovered spa surface directly exposed to sunlight
and high temperatures for an extended period is subject to permanent
damage. Damage caused by exposing the spa to this abuse is not
covered by 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).
Sundance constantly strives to offer the finest spas available,
therefore modifications and enhancements may be made which
affect the specifications, illustrations and/or instructions contained
herein.

least 5 feet (1.5m) from the spa water.
8. WARNING: To Reduce the Risk of Injury:
9. The water in a spa should never exceed 104°F (40°C). Water
temperatures between 100°F (38°C) and 104°F (40°C) are consid-
ered safe for a healthy adult. Lower water temperatures are recom-
mended for young children and when spa use exceeds 10 minutes.
10. 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
using a spa.
11. 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).
12. The use of alcohol, drugs, or medication before or during spa use
may lead to unconsciousness with the possibility of drowning.
13. Persons suffering from obesity or a medical history of heart disease,
low or high blood pressure, circulatory system problems, diabetes,
infectious diseases or immune deficiency syndromes should consult
a physician before using a spa. If you experience breathing dif-
ficulties in association with using or operating your spa, discontinue
use and consult your physician.
14. 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.
15. 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, dis-
continue use and seek medical attention.

physician before using a spa.
WARNING: Water temperature in excess of 38°C (104°F) may be
injurious 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 light, telephone,
radio, television, etc.) within 5 feet (1.5m) of this spa unless factory
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 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, and
an increase in the internal temperature of the body. The effects of hyper-
thermia 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.

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 drown-
ing.
4. Do not use the spa under the influence of alcohol, narcotics, or
other drugs. Use of the spa under these conditions may lead to seri-
ous consequences.
5. Always test the spa water temperature before entering the spa.
Enter 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” equip-
ment system. It contains the most advanced safety and self-protective
equipment in the industry. Nonetheless, this spa must be installed prop-
erly 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 13) to permit connection of a bonding wire between

Page 7
this point and any ground metal equipment, metal water pipe or conduit
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 assur-
ance 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 included 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 insufficient 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, flat, 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, reinforced 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 the spa. Placing the spa in a depression without provisions for
proper drainage could allow rain, overflow and other casual water
to flood the equipment and create a wet condition in which it would
sit. For spas which will be recessed into a floor 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 the cabinet side panels and access to the jets
components, especially on the side with the equipment bay doors.

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, be certain to make provisions for proper
ventilation. When the spa is in use, considerable amounts of moisture
will escape. This can damage certain surfaces over time. If you have
any questions regarding the placement or installation of your spa,
consult your authorized Sundance dealer.
WARNING: In addition to maintenance of filters and water
chemistry, proper ventilation is recommended to reduce the
risk of exposure to viruses and bacteria that could be present
in the air or water. Consult a licensed architect or building
contractor to determine your specific needs if installing your
spa indoors.

7.0 Spa Fill Up Procedure
FOR BEST RESULTS, READ EACH STEP IN ITS ENTIRETY
BEFORE PROCEEDING WITH THAT STEP.
1. Prepare The Spa For Filling
• Clear all debris from the spa. (Although the spa shell has been
polished at the factory, you may want to treat it with a specially
formulated spa cleaner. Consult your authorized Sundance
dealer for additional information prior to filling spa.
• Remove filter/skimmer lid (page 20), then remove filter cartridge
as outlined in section 11.1 (page 25).
2. Fill Spa
• Place the end of your garden hose into the empty filter bucket.
CAUTION: Never fill with water from a water softener. If your
water is extremely “hard”, it is preferable to fill half-way with
hard water and the rest of the way with softened water. Or,
you may fill entirely with hard water if you use a special water
additive available from your authorized Sundance dealer.
• Fill spa with clean tap water from garden hose until water covers
all jets (DO NOT OVERFILL!)
IMPORTANT: Always fill your spa through the filter bucket
after draining. Failure to do so may cause air to be trapped
in either pump, preventing the pump from circulating water.
Remove the hose and replace the filter cartridge. Note: DO
NOT overtighten filter cartridge, finger tight only!
3. Turn On Power
Turn on power to spa at the home’s circuit breaker. The heater
and filter pump will automatically activate. If the control panel LCD
flashes water temperature and “COOL” or “ICE”, refer to page 31 for
additional information.
4. Activate Jets Pump 1
Depress the JETS 1 button on the control panel once
to activate jets pump #1. On Burlington models, press
JETS 2 button to activate jets pump #2.

5. Add Start-Up Chemicals
Add the spa water chemicals as recommended by your autho-
rized Sundance dealer. See section titled “WATER QUALITY
MAINTENANCE” (page 29) for general guidance.
6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading between 3 ppm and 5 ppm
chlorine or 4 ppm and 6 ppm bromine. To ensure healthy water
conditions, always maintain a constant sanitizer reading within the
levels recommended by the Association of Pool And Spa Profession-
als/USA printed on the inside cover of this manual. If sanitizer levels
cannot be stabilized, perform the decontamination procedure steps
9-15 on the following page. Note: the “decontamination procedure”
steps 9-15 should also be used after the spa has been “Winterized”
(sec. 11.7) or has been sitting without power for an extended period.
7. Set Spa To Heat
To warm spa water to a comfortable temperature, follow these
steps:
• The LCD display on the control panel displays the actual
temperature of the spa water. Press either the COOLER
(Down) or WARMER (Up) button once to display the “set”
temperature for 5 seconds. If you want the water to
heat to a different temperature, simply press COOLER
or WARMER within 5 seconds. The set temperature
increases or decreases by one degree each time one of these
buttons is pressed.
• The heater will turn off when the temperature corresponding to the
thermostat setting is achieved.
Important Heater Details:
• The maximum temperature for which the spa can be set is 104°F
(40°C) and the minimum is 80°F (27°C).
• For 2-pump Burlington modes powered by a 40 amp service, jets
pump #1 must be set to low speed and jets pump #2 must be
turned off to operate the heater.
• Setting the thermostat at maximum will not accelerate the heating
process. This will only result in a higher ultimate temperature.
• The heater operates until the water reaches the programmed “set
temperature”, then turns off. The heater will reactivate after the
water cools to approximately 1.5° below the “set temperature.”

8. Place Cover On Spa
• Keeping the insulating cover in place anytime the spa is not in use
will reduce the time required for heating, thereby minimizing
operating costs.
• The time required for initial heat-up will vary depending on the
starting water temperature.
DANGER: Risk of injury, always check water temperature
carefully before entering spa!
Decontamination Procedure (Steps 9-15)
Steps 9-15 below are only required when sanitizer levels are unstable
after performing steps 1-6 above. Disregard steps 9-15 below if sanitizer
levels remain stable at 3 ppm to 5 ppm after performing steps 1-6 above.
9. Add 2.5 ounces of sodium dichlor for every 100 gallons of water.
Refer to the table below for approximate water ll volume by model.
CAUTION: Never add chlorine tablets (trichlor) to your
spa for any reason! This chemical may damage components
within your spa and void the manufacturer warranty.
Water Fill Volume by Model
Spa Model Approximate Fill Volume
Denali ........................................ 220 US Gallons (833 Liters)
Tacoma ...................................... 105 US Gallons (397 Liters)
Burlington .................................. 340 US Gallons (1,287 Liters)
10. Leave spa cover open during this step to allow excessive chemical
vapors to exit spa, protecting plastic knobs and pillows on Tacoma
and Burlington models from chemical attack. If spa is indoors, open
doors and windows for proper ventilation. Turn on all
spa jets pumps for one hour, open all air controls. On
Denali models, place the Divert-A-Jet in their center
“combo” position as shown (right). Note: You will need
to press the jets pump button(s) every 20 minutes since
these functions have an automatic 20 minute time-out
function that turns them off.
