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. With two pump 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:
with CLEARRAY® without CLEARRAY®
pH 7.4-7.6 7.4-7.6
Free chlorine no less than 1.0 ppm 3.0-4.0 ppm
Free Bromine no less than 2.0 ppm 2.0-4.0 ppm
Total Alkalinity 100-120 ppm 100-120 ppm
Calcium Hardness 150-250 ppm 150-250 ppm
IMPORTANT: CLEARRAY® Water Purication System is factory installed. If the
CLEARRAY® system is altered or is not operating efciently then follow the “without
CLEARRAY®” water chemistry parameters as dened by the Association of Pool
and Spa Professionals. CLEARRAY® requires an annual bulb replacement to
properly sanitize your water.
!TO DECREASE RISK OF INFECTION OR DISEASE! Always maintain
your spa lter as outlined below to ensure healthy spa water. Refer to page 34 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
34 for detailed lter cleaning/replacement instructions.
Required Water Maintenance
!TO DECREASE RISK OF INFECTION OR DISEASE! 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 39-40 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,
because 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 9).
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.

3.0 Important Safety Instructions for all Spa Owners
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY!
This spa was manufactured to meet the standards and specications
outlined in the “Virginia Graeme Baker Pool and Spa Safety Act” (VGB
Safety Act). When installing and using this spa, basic safety precautions
should always be followed, including:
1. !DANGER: RISK OF SEVERE INJURY OR DROWNING!
• Extreme caution must be exercised to prevent unauthorized access
by children.
• To avoid accidents, ensure that children do not use this spa unless
supervised at all times. Adult supervision is a critical safety factor in
preventing children from drowning.
• Use the straps and clip tie downs to secure the spa cover when not
in use. This will help discourage unsupervised children from entering
the spa. 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.
2. !DANGER: RISK OF SEVERE INJURY OR DROWNING!
• Keep hair, loose articles of clothing or hanging jewelry away from suction
ttings, rotating jets or other moving components to avoid entrapment
that could lead to drowning or severe injury.
• Never use the spa unless all suction guards, lter, lter lid, or skimmer
assembly are installed to prevent body and/or hair entrapment.
• Never operate or use the spa if the lter, lter lid, or skimmer assembly
are broken or any part of the skimmer assembly is missing. Please
contact your dealer or nearest service center for service.
• The suction ttings and suction covers in this spa are sized to match the
specic water ow created by the pump(s). If it is necessary to replace
the suction ttings, suction covers or pump(s), be sure that the ow rates
are compatible and are in compliance with the VGB Safety Act.
• Never replace a suction tting or suction cover with one rated less
than the ow rate marked on the original suction tting. Using improper
suction ttings or suction covers can create a body or hair suction
entrapment hazard that may lead to drowning or severe injury.
3. !DANGER: RISK OF SEVERE INJURY FROM ELECTRIC
SHOCK OR DEATH FROM ELECTROCUTION!
• Install the spa at least 5 feet (1.5m), from all metal surfaces. As an
alternative, a spa may be installed within 5 feet of metal surfaces
if each metal surface is permanently connected (bonded) by a
minimum No. 8 AWG (8.4 mm²) solid copper conductor attached
to the wire connector on the grounding lug, inside the equipment
compartment on the equipment box.

into the spa or slipping and falling, which could result in
unconsciousness, drowning, or serious injury. Remember that wet
surfaces can be very slippery.
• Never stand, walk or sit on the top railing of the spa.
5. !WARNING: RISK OF HYPERTHERMIA (OVER-HEATING)
CAUSING SEVERE INJURY, BURNS, WELTS OR DEATH!
• Water temperature in excess of 104°F (40°C) may be injurious to
your health.
• Refer to Section 3.2 Hyperthermia for specic causes and symptoms
of this condition.
• The water in the spa should never exceed 104°F (40°C). Water
temperatures between 100°F (38°C) and 104°F (40°C) are
considered safe for a healthy adult.
• Lower water temperatures are recommended for young children
(children are especially sensitive to hot water) and when spa use
may exceed 10 minutes.
• The Consumer Products Safety Commission/USA has stated that the
water temperature in a spa should not exceed 104°F (40°C).
• Always test the spa water temperature before entering the spa.
The user should measure the water temperature with an accurate
thermometer since the tolerance of water temperature-regulating
devices may vary as much as +/- 5°F (2°C).

3.1 Entrapment Risk
The Consumer Products Safety Commission/USA has reported that
users of pools and spas have become entrapped (stuck) to drain and/or
suction ttings causing death, drowning, or serious injury (see diagram
below). This spa was manufactured to meet the standards and specica-
tions outlined in the “Virginia Graeme Baker Pool and Spa Safety Act”
(VGB Safety Act). Entrapment risk can be minimized if proper precau-
tions are taken.
DANGER: RISK OF PERSONAL INJURY OR DEATH!
Never operate the spa if a suction tting, suction cover, lter,
lter lid or skimmer assembly are broken, damaged or missing.
!
NOTE: Suction covers must be replaced every ve years.
1. !DANGER: RISK OF SEVERE INJURY OR DROWNING!

covers, lter, lter lid or skimmer assembly.
3.2 Hyperthermia
Prolonged immersion in hot water may induce hyperthermia (over-
heating). The use of alcohol or drugs can greatly increase the risk of
fatal 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 spa;
• Physical inability to exit spa;
• Fetal damage in pregnant women; and
• Unconsciousness and danger of drowning.

A Warning Sign is provided in your warranty packet. Please install at
a location near your spa, where it is visible to users of the spa. For
additional or replacement Warning Signs please contact your local
Sundance spas dealer and reference item number #6530-082.
3.3 Important CSA Safety Instructions (Canada only)
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 Publication 417, Symbol 5019).
3. At least two lugs marked “Bonding Lugs” are provided on the
external surface or on the inside of the supply terminal box/
compartment. To reduce the risk of electric shock, connect the local
common bonding grid in the area of the spa to these terminals with
an insulated or bare copper conductor not smaller than No. 6 AWG
(10 mm²).
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 (10 mm²).
5. SAVE THESE INSTRUCTIONS.
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
equipment 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 16) to permit connection of a bonding wire between
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

Page 9
680 SERIES
within 5 feet (1.5m) of the spa. Bonding wire must be at least No. 8 AWG
(8.4 mm²) 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
included 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,
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 experience in this type of application.
!
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

Page 10
680 SERIES
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.
CAUTION: If the spa 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 spa 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 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.
• 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 spa for servicing, it is highly recommended
that you plan your outdoor installation to provide full access to the
entire spa. Please take this into consideration when placing the spa
in a deck or enclosed by a surrounding.
• Consider locating your spa away from any reective surface or glass
to prevent any damage to the synthetic skirt.
• Do not shim the spa. To ensure proper support the spa must sit at
on the intended foundation.

4.2 Indoor Location
For indoor installations many factors need to be considered before
installing a spa 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,
bacteria 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 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 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 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
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
authorities is not covered under the spas warranty. Please consult
your local state or city building ordinances.
• DO NOT SHIM THE SPA: To ensure proper support the spa must sit
at on the intended foundation.
