Attention New Spa Owner!
Congratulations on the purchase of your new Sundance®780 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 (Section 9.0, page 25). For 2 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 hot tub’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 main-
tain your spa lter as outlined below to ensure healthy spa water. Refer to pages
34-35 for additional information.
Required Filter Maintenance
Your new hot tub is equipped with an advanced 2-stage MICROCLEAN® water
ltration system that provides unsurpassed water quality! To ensure maximum
water quality at all times, you should clean and reuse the larger pleated lter
cartridge every month and replace (throw away) the smaller MICROCLEAN lter
cartridge every 3 months, or earlier as necessary. The smaller MICROCLEAN
lter cartridge is designed to be thrown away! Attempts to reuse this lter
cartridge may result in the re-release of unwanted particles back into the spa.
See pages 34-35 for detailed lter cartridge 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 41-42 for additional information.

1.0 Important Spa Owner Information
Your new Sundance®780 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 efficient operation, an uncovered acrylic spa surface and
wall fittings 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 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 10).
We constantly strive to offer the finest spas available, therefore

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.

3.2 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 Additional 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.

780 SERIES
3.4 General Electrical Safety Instructions
Your new Sundance®780 Series 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 17) 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
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
ensure installation conforms to local building codes.
120/240 Volt Dover Convertible Model
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 feet (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.

Page 10
780 SERIES
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
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 doors.
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).
!

Page 11
780 SERIES
• 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 specifically 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 sufficiently handle excessive water spillage. Be
sure the flooring 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 flooring 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.
5.0 Power Requirements
Sundance®spas are designed to provide optimum
performance and exibility of use when connected to the
maximum electrical service listed on pages 13-14. If you
prefer, your qualified technician can perform a minor circuit
board modication to allow your spa to accept an electrical service other
than the factory setting.
Note: Refer to pages 50-53 for circuit board conguration details or
contact your authorized Sundance dealer.
