Attention New Spa Owner!
Congratulations on the purchase of your new Jacuzzi® spa! The following is a list
of automated functions performed by your spa. These functions are listed below
in an attempt to suppress any operational concerns you may have during the rst
24-hours of ownership! Also listed below are important maintenance recommen-
dations you should observe on a regular basis to protect your new investment.
Automated Operations
Approximately two minutes after power is applied to the spa, the rst skimming/
heating cycle turns on pump 1. In J-335 and J-345 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 spas lter as outlined below to ensure healthy spa water.
Refer to page 33 “Water Quality Maintenance” 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 the lter cartridge every three months, or earlier as necessary. See
page 27-29 for detailed lter cartridge cleaning/replacement instructions.
Required Water Replacement
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 33 for additional information.
pH 7.2 - 7.4
Free Chlorine 3-5 ppm
Free Bromine 4-6 ppm
Total Alkalinity 100-120 ppm

3. DANGER: Risk of Accidental Drowning. Extreme caution must be
exercised to prevent unauthorized access by children. To avoid
accidents, ensure that children cannot use this spa unless they are
supervised at all times.
4. DANGER: Risk of Injury. The suction fittings in this spa are sized to
match the specific water flow created by the pump. Should the need
arise to replace the suction fittings or the pump, be sure that the
flow rates are compatible. Never operate the spa if the suction fit-
tings are broken or missing. Never replace a suction fitting with one
rated less than the flow rate marked on the original suction fitting.
5. DANGER: Risk of Electric Shock. Install 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 con-
nected (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.
6. DANGER: Risk of Electric Shock. Do not permit any electrical appli-
ance, such as a light, telephone, radio, television, etc. within 5 feet

turer.
7. ELECTRICAL SUPPLY: The electrical supply for this product
must include a suitably rated switch or circuit breaker to open all
ungrounded supply conductors to comply with section 422-20 of the

Page 3
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.
8. WARNING: To Reduce the Risk of Injury:
9. 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 consid-
ered safe for a healthy adult. Lower water temperatures are recom-
mended for young children and when spa use may exceed 10 min-
utes.
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
temperature 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.

A warning sign is provided in your warranty packet. Please
install it at a location near your spa, where it is visible to the
user of the spa. For additional or replacement signs please con-
tact your local Jacuzzi dealer and reference item number #6530-
082.
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.

Page 7
3.0 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 the manufacturers 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 servic-
ing. 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.
3.1 Outdoor Location
In selecting the ideal outdoor location for your spa, we suggest that you
take into consideration:
1. The proximity to changing area and shelter (especially in colder
weather).
2. 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).
3. The closeness to trees and shrubbery (remember that leaves and
birds could create extra work in keeping the spa clean).
4. A sheltered environment (less wind and weather exposure can
result in lowered operation and maintenance costs).
5. 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.

Page 8
3.2 Indoor Location
For indoor installations, be certain to make provisions for proper ven-
tilation. 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 Jacuzzi 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.
4.0 General Electrical Safety Instructions
Your new Jacuzzi® 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
insure dependable usage. Please contact your dealer or local building
department should you have any questions regarding your installation.
Proper grounding is extremely important. Jacuzzi 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 12) 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 with-
in 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 this spa, check with the local building depart-
ment to insure installation conforms to local building codes.
120/240 Volt J-315 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 equip-
ment 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.

Page 9
5.0 Power Requirements
Jacuzzi® spas are designed to provide optimum performance and flex-
ibility of use when connected to the maximum electrical service listed in
the tables below. If you prefer, your dealer can perform a minor circuit

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 for-
mulated spa cleaner. Consult your authorized Jacuzzi dealer for
additional information prior to filling spa.
• Remove filter lid then remove filter cartridges from filter bucket.
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 addi-
tive available from your authorized Jacuzzi dealer.

• Fill spa until water covers all jets but does not touch the bottom of
the lowest headrest. DO NOT OVERFILL.
IMPORTANT: Always fill your spa through the filter bucket after drain-
ing. Failure to do so may cause air to be trapped in either pump, pre-
venting the pump from circulating water. Remove the hose and replace
both filter cartridges.
3. Turn On Power
Turn on power to spa at the home’s circuit breaker. The heater and
filter/circulation pump will automatically activate. If the control panel
LCD flashes water temperature and “COL” or “ICE”, refer to page
36 for additional information.
4. Activate Jets Pump 1
Depress the JETS 1 button on the control panel once to
activate jets pump #1.
5. Add Start-Up Chemicals
Add the spa water chemicals as recommended by your authorized
Jacuzzi dealer. See section 12.0 “Water Quality Maintenance” (page
33) for general guidance.
6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading between 3 ppm and 5 ppm. To
ensure healthy water conditions, always maintain a constant sani-
tizer reading within the levels recommended by the Association of
Pool And Spa Professionals/USA printed on the inside cover of this
manual. If sanitizer levels cannot be stabilized, perform the decon-
tamination procedure steps 9-15 on page 15-17. Note: the “decon-
tamination procedure” steps 9-15 should also be used after the spa
has been “Winterized” (section 11.7, page 32 ) 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 tempera-
ture of the spa water. Press either the COOLER (-) or WARMER (+)
button once to display the “set” temperature for 5 seconds. If you
want the water to heat to a different temperature,

Page 15
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).
• 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 operat-
ing costs.
• The time required for initial heat-up will vary depending on the start-
ing water temperature.
DANGER: Risk of injury, always check water temperature care-
fully 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 sani-
tizer levels remain stable at 3 ppm to 5 ppm after performing steps 1-6.
9. Add 2.5 ounces of sodium dichlor for every 100 gallons of water.
Refer to the table on page 16 for approximate water ll volume by
model.
CAUTION: Never add chlorine tablets (trichlor) to your spa for
any reason! This chemical may damage your spa and void the
manufacturer warranty.

10. Leave spa cover open during this step to allow excessive chemical
vapors to exit spa, protecting pillows and plastic knobs from chemical
attack. If spa is indoors, open doors and windows for proper ventila-
tion. Turn on all spa jets pumps for one hour, open all air controls,
and place all massage selector knob(s) 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.
CAUTION: never leave your spa unattended for any reason
while the cover is open and accessible to small children and
animals!
11. Turn off power to the spa at the circuit breaker, then drain tub as
outlined in section 11.2 “Draining And Relling” (page 29-30).
12. Fill spa until water covers all jets but does not touch the bottom of
the lowest headrest. DO NOT OVERFILL.
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 addi-
tive available from your authorized Jacuzzi dealer.
13. Consult your authorized Jacuzzi dealer for chemical recommenda-
tions, then add chemicals to spa water to achieve a constant sani-
tizer reading within the levels recommended by the Association of
Pool And Spa Professionals/USA printed on the inside cover of this
manual.
14. Turn on all jet(s) pumps when adding chemicals to ensure proper
mixing and leave your spa cover open until the sanitizer level falls
below 5 ppm to protect pillows and plastic knobs from chemical at-
tack.
