Attention New Spa Owner!
Congratulations on the purchase of your new Jacuzzi Premium 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 con-
cerns you may have during the first 24-hours of ownership! Also listed
below are important maintenance recommendations you should observe
on a regular basis to protect your new investment.
Automated Operations
Your new spa is equipped with an automated “blow-out” cycle that clears
all plumbing lines daily to promote maximum water sanitation. Each day
at 12:00 PM (noon), pump 2 (and J-380 pump 3) will automatically turn
on for a period of one minute, then go off. Then pump 1 will turn on
and run for one minute to complete the cycle. Be aware, the factory
programmed blow-out cycle cannot be canceled or altered! However, If
you set one of four programmable skimming/heating cycles to overlap or
start at 12:00 (noon), pump 1 will turn on as programmed and operate
for the duration of the programmed cycle, overriding the factory “blow-
out” cycle. See page 30 for detailed skimming/heating cycle program-
ming instructions.
Filter Maintenance
Your new spa is equipped with an advanced 2-stage water filtration
system that provides unsurpassed water quality! To ensure maximum
water quality at all times, you should clean and reuse the skimmer bag
and both filter cartridges once a month. See page 33-34 for detailed
cleaning instructions.
Water Maintenance
You will want to replace the spa’s water every 3 to 6 months. The
frequency depends on a number of variables including the frequency of
use, number of users, attention paid to water quality maintenance, etc.
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 39 for additional information.

1.0 Important Spa Owner Information
Your Jacuzzi® Premium 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 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 sun-
light and that you keep the Jacuzzi 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 6).

3. WARNING: A grounding wire connector is provided on this unit to con-
nect a minimum No. 8 AWG (8.4mm2) solid copper conductor between
this unit and any metal equipment, metal enclosures of electrical equip-
ment, metal water pipe, or conduit within 5 feet (1.5m) of the unit.
4. DANGER: Risk of Accidental Drowning. Extreme caution must be exer-
cised to prevent unauthorized access by children. To avoid accidents,
ensure that children cannot use this spa unless they are supervised at all
times.
5. 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 fittings are broken or
missing. Never replace a suction fitting with one rated less than the flow
rate marked on the original suction fitting.
6. 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 connected (bonded) by a
minimum No. 8 AWG (8.4mm2) solid copper conductor attached to the
wire connector on the grounding lug, inside the equipment compartment
on the equipment box.
7. DANGER: Risk of Electric Shock. Do not permit any electrical appliance,
such as a light, telephone, radio, television, etc. within 5 feet (1.5m) of a
spa, unless such appliances are built-in by the manufacturer.
8. 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 National Electrical Code,
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.
9. WARNING: To Reduce the Risk of Injury:
A. The water in a spa should never exceed 104 °F (40 °C). Water tempera-
tures 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 and when spa use exceeds 10 minutes.
Page 2

B. Since excessive water temperatures have a high potential for causing fetal
damage during the early months of pregnancy, pregnant or possibly preg-
nant women should limit spa water temperatures to 100 °F (38 °C). If
pregnant, please consult your physician before using a spa.
C. 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).
D. The use of alcohol, drugs, or medication before or during spa use may
lead to unconsciousness with the possibility of drowning. 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.
E. Persons suffering from obesity or a medical history of heart disease, low
or high blood pressure, circulatory system problems, or diabetes should
consult a physician before using a spa.
3.1 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 compart-
ment. To reduce the risk of electric shock, this terminal must be con-
nected 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 (10mm2).
4. All field-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 (10mm2).
5. Save These Instructions:
A. WARNING: Children should not use spas without adult supervision.
B. WARNING: Do not use spas unless all suction guards are installed to

K. WARNING: Do not permit electric appliances (such as light, telephone,
radio, television, etc.) within 5 feet (1.5m) of this spa unless factory
installed.
L. CAUTION: Maintain water chemistry in accordance with manufacturer’s
instructions.
M. 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 hyperthermia include:
AUnawareness 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 pres-
sure, and any condition requiring medical treatment, pregnant women,
the elderly, or infants should consult with a physician before using a spa.
Page 4

2. The Consumer Products Safety Commission 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 exposures at
higher temperatures can cause high body temperature. Symptoms may
include dizziness, nausea, fainting, drowsiness, and reduced awareness.
These effects could possibly result in drowning.
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 serious conse-
quences.
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 entering the spa
and keep the spa cover secure in high-wind conditions. There is no rep-
resentation that the cover, clip tie-downs, or actual locks will prevent
access to the spa.
3.4 GENERAL ELECTRICAL SAFETY INSTRUCTIONS
Your new Jacuzzi Premium spa is equipped with a "state-of-the-art" equip-
ment 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 Premium spas are
equipped with a current collector system. A pressure wire connector is pro-
vided on the surface of the control box, located outside the equipment door
(Figure B, Page 10) 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 (8.4mm2)
solid copper wire. This is a most important safety assurance feature. Before
installing this spa, check with the local building department to insure instal-
lation conforms to local building codes.
Page 5

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, dam-
age to the skirt and/or the spa shell may result. Damage caused by improp-
er support is not covered under warranty. It is the responsibility of the spa
owner to assure the integrity of the support at all times.
We recommend a poured, reinforced concrete slab with a minimum thickness
of 4 inches (10cm). Wood decking is also acceptable provided it is con-
structed 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.
4.1 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.
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 Jacuzzi
Premium dealer.

7.0 Start-Up Instructions
Congratulations! You are now all set to get your new spa ready to use. Simply
follow this step-by-step procedure and, before long, you will be enjoying your
first glorious experience in your Jacuzzi Premium spa. For best results, read
each step in its entirety before proceeding with that step.
7.1 Filling the Spa
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
and wax available from your dealer prior to filling the first time.
Remove the filter cover, then remove and clean the strainer bag and both
filter cartridges as outlined in section 12.1 (Page 33-35). Place the end of
your garden hose into the exposed pump #1 filter wall fitting without a
mesh grill. Fill the spa half way, then place end of your garden hose into
the circulation pump filter wall fitting with the mesh grill. Continue filling
spa until the water level is 1 inch below the lowest pillow and and above all
jets. Do not over fill. 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
Jacuzzi Premium dealer. Always refill spa through both filter wall fittings
to purge trapped air from pump intakes. Failure to do so may cause air to
be trapped in either pump #1 or the circulation pump’s intake (air lock),
preventing either pump from circulating water. After filling, make sure
both filters are installed properly before applying power to the spa. Refer
to section 12.1 (Page 33-35) “Cleaning the Filters” for specific cleaning
and installation instructions.
7.2 Safety Check
Open the wood cabinet access panel and check all pump unions to make sure
they are hand tight. Loosening can occur during shipping and handling.
7.3 Turn on Power
Turn on power to spa at the home’s circuit breaker. The heater and circulation
pump will automatically activate. If the control panel LCD flashes water tem-
perature and “COOL” or “ICE”, the pump 1 will also activate in low speed. If
this occurs, refer to page 41-42 for additional information.

Page 11

7.5 Add Start-Up Chemicals
Add the spa water chemicals as recommended by your Jacuzzi Premium
Dealer. Refer to section 13.0 (Page 39) for general guidance.
7.6 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 and the capacity of your spa. Smaller spas heat at a rate of
approximately 8 to 10 degrees per hour; larger spas heat at about 4 to 6
degrees per hour.
WARNING: RISK OF INJURY. Always check water temperature
carefully before entering spa.
