1.0 Read and Follow These Important Instructions
When using the electrical equipment, basic safety precautions should always be followed. A
green colored 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 con-
tinuous copper wire equivalent in size to the circuit conductors supplying this equipment. At least
two lugs marked “BONDING LUGS” are provided on the external service or on the inside of
the supply terminal box or compartment. To reduce the risk of electric shock, connect the local
common bonding grid in the area of the spa or spa to these terminals with an insulated or bare
copper conductor not smaller than No. 6 AWG. All eld-installed metal components such as rails,
ladders, drains, or other similar hardware within three meters of the spa or spa shall be bonded
to the equipment grounding bus with copper conductors not smaller than No. 6 AWG.
2.0 Important Hot tub Owner Information
Your hot tub 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 hot tub
for efcient operation, an uncovered hot tub 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 hot tub to this abuse is not covered under warranty. We recom-
mend that you always keep the hot tub full of water when it is exposed to direct sunlight and that
you keep the insulating cover in place at all times when the hot tub is not in use. Read and care-
fully follow the requirements for your hot tub’s support base found in the Section titled, “Choosing
a Location” (page 8).
3.0 FCC Notice

4.0 Important Safety Instructions for all Hot tub Owners
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY!
This hot tub 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 hot
tub, 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 hot tub 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 hot tub cover when not in use. This will help
discourage unsupervised children from entering the hot tub. Keep the hot tub cover secure in
high-wind conditions.
• There is no representation that the cover, clip tie-downs, or actual locks will prevent access to
the hot tub.
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 hot tub unless all suction guards, lter, lter lid, or skimmer assembly are
installed to prevent body and/or hair entrapment.
• Never operate or use the hot tub 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 hot tub 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 hot tub at least 5 feet, from all metal surfaces. As an alternative, a hot tub may

4.1 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 seri-
ous 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). Entrap-
ment risk can be minimized if proper precautions are taken.
DANGER: RISK OF PERSONAL INJURY OR DEATH!
Never operate the hot tub if a suction tting, suction cover, lter, lter lid or skimmer
assembly are broken, damaged or missing.

Executive Series
5.0 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. Wood decking is also
acceptable provided it is constructed so that it meets the requirements outlined above.
Note: This spa is not intended nor designed to be used in a commercial or public application.
Use of this spa in public or commercial application will VOID the warranty. The spa buyer shall
determine whether there are any code restrictions on the use or installation of this spa since local
code requirements vary from one locality to another.
Site preparation, alterations to home owner’s property and permits (if any) are the sole responsi-
bility of the owner. ThermoSpas spas are not intended for commercial applications.
WARNING: For spas that are to rest on balconies, roofs or other platforms not spe-
cically tied into main structural support, consult a professional Structural Engineer with
experience in this type of application.
WARNING: Proper drainage is required. The installation must not allow the spa
equipment bay to become ooded or wetted (by external water). It is your responsibility,
and the responsibility of any installation contractor you hire, to make sure that all ap-
plicable codes and/or local construction requirements are met. If in doubt, refer to the
building authority responsible for approving the proposed installation site.
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, leaks from spa
plumbing, and other casual water to ood the equipment and create a wet condition in which it
would sit in. For spas which will be installed below grade or 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 spa is indoors or located in an enclosed area, proper ventilation should
be discussed with an Engineer or authority competent enough to understand the nec-
essary 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.
5.1 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).

Choosing a Location

9
Executive Series
• 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.
• Floor load capacity must be a minimum of 100 lbs. per square foot and must meet your local
building codes. Swim spas and spas over 39" in depth require higher load capacity. Reference
page 68 for information.
• Spa can not be installed on asphalt, laid in dead sand or on stone dust.
• Spa can not be placed directly on a gravel or lawn surface.
• Delivery crew is not equipped to level and/or repair spa sites.
• Most spa servicing is performed on the spa equipment that is located behind the side cabinet
panels of the spa. It is important to install the spa to allow easy access to the spa equipment.
We recommend an 18" minimum clearance around all sides of the spa to avoid additional
service charges. Providing service access is the responsibility of the owner.
• !WARNING: Do not rest your spa directly on top of a power line. Electrical shock or
power failure may result. The power line to the spa should be routed through the side wall by
drilling a hole.
5.2 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 venti-
lation 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 spa 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.
• Spas installed indoors must be placed on a non-porous surface with a drain.
• Do not put the spa on a carpet or hardwood oors due to possible splash out from the tub.
Water will accumulate around the spa, so ooring materials must provide a good grip when
wet. Water damage to the home owner’s property from splashing or leaks are at the home
owner’s risk. This is not covered under any ThermoSpas warranty.
• Adequate ventilation must be provided in order to allow for chemical fumes to escape. Take
into consideration that these fumes could enter other indoor areas.
• When the spa is installed indoors or outdoors, adequate room must be provided to allow the
cover and lifter to operate and function properly. Depending of the lifter used, up to 50% of
the cover is exposed. There should be sufcient room accounted for the spa height plus cover
lifter measurement, Figure 1.
• Consult your local state or city building ordinances to ensure installation is in accordance
with local codes. Any damage caused if you do not follow these guidelines voids the spa’s
warranty.
• Most spa servicing is performed on the spa equipment that is located behind the side cabinet
panels of the spa. It is important to install the spa to allow easy access to the spa equipment.
We recommend an 18" minimum clearance around all sides of the spa to avoid additional
service charges. Providing service access is the responsibility of the owner.

6.0 Electrical Set Up
Before beginning the wiring process turn off the circuit breaker so that no
power is connected to the controller. ThermoSpas recommends all spa wiring to
be done by a licensed electrician. Improper wiring may void your warranty. Incorrect
or incomplete wiring will very likely create a dangerous hazard. Performing a conver-
sion or any other modication to the original hardware or installation conguration
mandates that the owner assumes full responsibility for assuring that the resulting
system complies with all applicable national, state, and local wiring codes and ordi-
nances for the location of the unit. Be aware that there are major differences in wiring
codes if this unit is to be installed at any location other than a private residence.
The Safe Electrical Hook-up of Your Spa
• The electrical installation of your spa must be done by a qualied electrician in accordance
with the National Electrical Code (NEC), and all local codes effective at the time of installation.
• Your spa must be installed on a dedicated electrical circuit. No other appliances or electrical
equipment may be used on this circuit.
!WARNING: If your spa is not installed in accordance with the NEC, it may create a dan-
gerous safety hazard. Improper electrical installation may also damage the inner workings of a
spa and void your warranty.
!WARNING: If your electrician is not absolutely sure how to correctly connect your system,
call the ThermoSpas Technical Service Department at 800.876.0158, option 2. Mistakes may
be costly and will void your equipment warranty. Before beginning the wiring process turn off the
circuit breaker so that no power is connected to the controller. ThermoSpas recommends all spa
wiring to be done by a licensed electrician. Improper wiring may void your warranty.
Electrical Service Requirements
Before wiring for a spa, one of the rst considerations is whether or not your main service or
sub-panel feeding your spa has the capacity to provide sufcient power to your spa. A licensed
electrician will be able to perform a load calculation to determine this.
Select the inlet you want to use, drill a hole large enough for the wires on the skirt panel and
then feed the power cable through to the control box. To allow access you will have to trim/cut
the ThermoFoil blanket under the skirt. For access from underneath the spa, please contact the
Service Department for help (800.876.0158).
Note: You can use any of the four side of the spa to drill a hole for the power cable. The panels
are not predrilled.
The electrical requirements for your spa are found on the Electrical Guide Sheet contained in the
Welcome Kit for your specic model. It is very important to review your electrical requirements
before starting installation.
Removing the cabinet panels
A. Standard Cabinet:
1. Remove screws from the trim pieces and front center panel. Place
the panels in a safe location to prevent from damaging it.

4. Remove screws from the controller to expose the wiring
terminal.
5. To reinstall the panel just follow the steps above in reverse
order.
Electrical Service Considerations
The Electrical Service determines how many pumps can run in conjunction with the heater. If the
dedicated GFCI circuit was installed with a smaller breaker than the recommended size (typically
60 amps), your heater will automatically shut off to avoid tripping your circuit breaker if too many
pumps are activated (including the blower). Heating will automatically turn back on after pumps
have been shut off. The heater will also automatically shut off on larger spas when 3 or more
pumps (including the blower) are turned on. All of this may occur even though the circulation
pump continues to run – when the heater is on, progressing bars will be indicated from the bot-
tom to the top of the heater icon.
!WARNING: Wiring to your spa must be COPPER ONLY! Note that the wiring from a main
panel to a sub-panel for the spa must be copper and the sub-panel is rated for copper (CU).
The length of the wiring from the panel or feed to your spa also has to be determined. If the total
run exceeds 75 feet, the wire size must be increased by one wire size to adjust for the corre-
sponding voltage drop. To make future service work easier we recommend leaving at least 6'
of slack in the main electrical wire which may be coiled inside the cabinet. Ground Fault Circuit
Interrupt (GFCI) Requirements: All spa electrical circuits must be GFCI protected on a dedicated
circuit.
It is common practice for electrical service for a spa to be supplied by a regular two-pole breaker
at the rated amperage at the main panel, and the disconnecting means (NEC Article 100) is usu-
ally a 125-amp sub-panel with the required GFCI breaker(s) mounted inside. The GFCI breaker
becomes the required disconnecting means. These sub-panels sometimes will not have a ground
bar included and it must be purchased separately. The ground bar is a small metal bar with holes
provided for ground wires and screws to secure the wires to the ground bar. This ground bar is
NOT to be bonded or connected to the neutral bar, and the neutral bar must be isolated from any
grounding source. The GFCI pigtail in this instance is connected into the neutral bar—not the
ground bar.

7.0 Spa Start Up
Please read through all steps before beginning. This section explains the necessary procedures
required to start up your spa. Familiarize yourself with this procedure prior to beginning the pro-
cess. Use this procedure as a guideline.
• Make sure you have any instructions along with the Welcome Kit and Chemical Starter Kit
prior to lling your spa.
• If your water is acidic, hard, or has a high mineral content it is recommended to contact one of
our trained Customer Care Representatives prior to lling your spa.
• Failure to follow these start-up instructions for your spa and observe the recommended
maintenance time periods may result in pump damage or require draining and relling the spa.
Chemical balancing may take 3-7 days to settle in, based on the following variables.:
1. Incoming water temperature and water pressure (ll rate)
2. Size and type of spa
3. Water characteristics (hardness, mineral content)
4. Desired nal water temperature
5. Ambient conditions
Inspect and Filling you spa
Once your spa is in its nal location it is time to inspect it to ensure it is ready to be lled. Gently
remove all packing and crating materials from the spa.
Step 1: Remove the panels/insulation of the spa so you can see the interior.
Step 2: Remove filters, the accessory bag and the spa chemical starter kit located inside the
spa shell.
Step 3: Wipe spa clean with a soft damp sponge. Be careful not to scratch the surface with any
particles that may have fallen into the tub.
Step 4: Make sure the “T” valves on each water pump are open by pulling them up as far as
they will go and locking them in the open position, page 53.
Step 5: Make sure all water pump and heater unions are tight, page 53.
Step 6: Make sure the drain valve is closed, page 53.
Step 7: Install the filter(s).
Step 8: In certain situations, if your water is extremely “hard,” it is preferable to ll half-way with
hard water and the rest of the way with softened water. Water that is too soft can be
corrosive to metal components.
Step 9: Let the water run out of your garden hose for several minutes before filling the spa. This
will flush out stagnant water in the line that may cause bacteria.
Note: We suggest putting a sock over the end of your hose to act as a strainer and protect the
spa shell acrylic from the hose.
Spa Start Up

15
Executive Series
Step 10: Begin filling your spa up to 1” below the pillows. The actual water level may vary
depending on the bather load. When there are no bathers in the spa, the water must
be high enough to prevent pump surge and low enough that when the recommended
number of bathers are in the tub that the water is not overflowing out of the spa. The
recommended water level is half way up the filter area with no bathers. While spa is
filling periodically check underneath to be sure unions are tight and not leaking.
Note: Unions are located on both the spa’s water pump(s) and heater. It is imperative that they
are checked and tightened before filling the spa. Although every spa is thoroughly tested twice in
our factory during final inspection, some connections may loosen during transport from the
factory to your home.
Heat Water
Step 1: Set desired temperature by pressing the Warm ( ) or Cool ( ) button.
Step 2: Install insulated cover, close it over spa, and secure it with the lock down straps.
Step 3: Allow between 5 and 24 hours for the water to reach the desired temperature. A 240-volt
service will raise it approximately 4° to 8°F per hour.
DANGER: RISK OF PERSONAL INJURY.
Check water temperature carefully before entering hot tub! Excessive water tempera-
ture can cause burns, welts and body temperature to rise, hyperthermia (over-heating).
Prep Water: Maintaining Correct Water Chemistry and Safety
Improper use of spa chemicals may be dangerous and could damage your spa and its cover.
Since this damage is not covered by your warranty; it is extremely important to take precautions
when using these products. Only use chemicals and cleaning agents designed for spas. Damage
resulting from the use of non-recommended chemicals and/or cleaning agents is not covered
under the warranty. Following the procedures in this guide will make the maintenance and care of
your spa simple and economical.
Avoid using any biguanide or copper-based algaecide with your spa. Use of these products is not
recommended by ThermoSpas and may void your warranty.
CAUTION: RISK OF PERSONAL INJURY OR SPA DAMAGE!
Never add chlorine tablets (trichlor) or acid to your hot tub for any reason! These chem-
icals may damage components within your hot tub, burn or irritate your skin, create a
rash, and void the manufacturer warranty for your spa.

Proper Handling of Chemicals
1. Keep all chemicals out of reach of children.
2. Always keep lids on chemicals when not in use and store them in a cool, dry location away
from direct sunlight.
3. Do not store chemicals within the interior of the spa’s cabinet.
4. Do not interchange caps or measuring scoops for different types of chemicals.
5. Do not smoke around chemicals. Some can emit highly ammable fumes.
6. In case of contact or if a chemical is swallowed, call a doctor or local Poison Control Center.
If a doctor is required, bring the chemical container with you so the doctor can determine the
appropriate treatment.
7. Never mix chemicals or chemical solutions directly with each other.
8. Always add chemicals to water when mixing them. Never add water to chemicals.
9. When in doubt, call Customer Care at 800-876-0158.
WARNING: RISK OF POISONING OR DEATH.
Never leave chemicals opened and accessible to anyone. Use chemicals according to
the vendors instructions. Always store chemicals in a safe and/or locked location. Keep
away from and out of reach of children.
Proper Procedure for Adding Chemicals
Proper water chemistry is essential to the safety of the user as well to the life of the spa compo-
nents. Improper water chemistry may cause skin irritation or facilitate the transmittal of disease.
Proper water chemistry is the sole responsibility of the spa owner. The costs incurred from injury
or damage resulting from improper water chemistry are not covered under the ThermoSpas, Inc.
warranty.
1. Turn on jets pump(s) when adding chemicals to ensure proper mixing and leave your spa
cover open until the sanitizer level becomes stable to protect pillows and plastic knobs from
chemical attack.
2. Do not add chemicals through the skimmer.
3. Only add one chemical at a time. Unless otherwise specied always wait at least 10 minutes
after adding chemicals to your spa before adding more chemicals.
Note: Depending on the metals or mineral content of your tap water, one of the chemicals in
the treatment may react to cause a discoloration or formation of a precipitate. In this event you
should not have to drain your spa. There are treatments to solve this problem. If you have any
questions contact Customer Care.
WARNING: BECAUSE OF THE RISK OF INHALING CHEMICAL VAPORS.
• To decrease the risk of injury, drowning or entrapment, never leave your hot tub un-
attended for any reason while the cover is open and accessible, especially to small
children and animals!
• Precautions should be taken to minimize your exposure to chemical vapors (that
could cause lung, brain, or skin damage).
