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 alleviate any operational concerns 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
Approximately two minutes after power is applied to the spa, the first filtration/
heating cycle turns on pump 1. An automatic five minute “blow-out” function
also activates pump 2 for a period of five minutes to flush all lines. Then, after five
minutes, pump 2 turns off and pump 1 continues to operate for the duration of the
cycle. Note: This function only occurs during the first filtration/heating cycle each
day.
Maintain Healthy Spa Water
Always maintain your spa’s water chemistry within the following parameters as
defined by the Association of Pool And Spa Professionals/USA:
pH 7.4-7.6
Free Chlorine 3.0-4.0 ppm
Free Bromine 2.0-4.0 ppm
Total Alkalinity 100-120 ppm
Calcium Hardness 150-250 ppm
Always maintain your spas filter as outlined below to ensure healthy spa water. Refer
page 32 “Water Quality Maintenance” for additional information.
Required Filter Maintenance
Your new spa is equipped with an advanced water filtration system that provides
unsurpassed water quality! To ensure maximum water quality at all times, you
should clean both filter cartridges every month, or earlier as necessary. See page 26
for detailed filter 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 param-
eters. See page 32 for additional information.

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:
1. Unawareness of impending hazard;
2. Failure to perceive heat;
3. Failure to recognize the need to exit spa;
4. Physical inability to exit spa;
5. Fetal damage in pregnant women; and
6. Unconsciousness and DANGER of drowning.
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 addi-
tional or replacement signs please contact your local Jacuzzi spas dealer
and reference item number #6530-082.
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.
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.
5

J-300 Series
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 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 entering the spa and
keep the spa cover secure in high-wind conditions. There is no representa-
tion that the cover, clip tie-downs, or actual locks will prevent access to the
spa.
3.4 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 equipment in the
industry. Nonetheless, this spa must be installed properly to ensure depend-
able usage. Please contact your local Jacuzzi 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 13) 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 impor-
tant safety assurance feature.
Before installing your spa, check with your local building department to insure
installation conforms to local building codes.
6

J-300 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,
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
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 constructed so that it meets the requirements outlined above.
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, overflow and other casual water to flood the equipment and create
a wet condition in which it would sit in. 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 all side cabinet side panels and access to the jet components,
especially on the side with the equipment bay.
4.1 Outdoor Location
In selecting the ideal outdoor location for your spa, we suggest that you take
into consideration:
• The proximity to changing area and shelter (especially in colder 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.
7

J-300 Series
4.2 Indoor Location
For indoor installations many factors need to be considered before installing a
spa indoors:
1. 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.
2. 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 the entire contents
of the spa. Be sure to make provisions for ceilings and 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 struc-
tures should be able to withstand or resist water and moisture.
3. Proper Ventilation: Proper ventilation should be discussed with an
Engineer or authority competent enough to understand the necessary provi-
sions 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 which can
damage certain surfaces and/or surroundings.
4. 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.
5. Warranty: Damage caused by not following these guidelines or any
improper installation not in accordance to local codes or authorities is not
covered under the spas warranty. Please consult your local state or city
building ordinances.
WARNING: In addition to maintenance of filters and water chemis-
try, proper ventilation is recommended to reduce the risk of expo-
sure 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.

8.0 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 formulated spa cleaner.
Consult your authorized Jacuzzi dealer for additional information prior to
filling spa.
Remove filter cover, then remove filter cartridge as outlined in section 12.1
(page 26).
2. Fill Spa
Place the end of your garden hose into the empty filter bucket.

J-300 Series
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 additive 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
draining. Failure to do so may cause air to be trapped in either
pump, preventing the pump from circulating water. Remove
garden hose and replace filter cartridge. DO NOT OVERTIGHTEN!
FINGER TIGHT ONLY!
3. Turn On Power
Turn on power to spa at the home’s circuit breaker to start boot up sequence
(sec. 10.0, page 21). The heater and filter pump will automatically activate after
several seconds. If the control panel LED flashes water temperature and “COL”
or “ICE” this is normal, refer to page 33 for additional information.
4. Activate Jets Pumps
Turn on jets pump(s) to ensure proper mixing when adding
start-up chemicals in step 5.
5. Add Start-Up Chemicals
Add the spa water chemicals as recommended by your authorized Jacuzzi dealer.
See section 13.0 “Water Quality Maintenance” (page 32) for general guidance.
6. Establish A Stable Sanitizer Reading
Establish a stable sanitizer reading between 3.0-4.0 ppm chlorine or 2.0-4.0
ppm bromine. To ensure healthy water conditions, always maintain a constant
sanitizer 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 decontamination procedure steps 9-16
on page 16-18. Note: the “decontamination procedure” steps 9-16 should also
be used after the spa has been “Winterized” (section 12.7 page 31) 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:
•
15

J-300 Series
The LED display on the control panel displays the actual temperature 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, 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 thermo-
stat setting is achieved.
Important Heater Details:
The maximum water temperature setting for your spa is 104°F (40°C) and
the minimum setting is 65°F (18°C).
For North American spas connected to a 40 amp service, jets pump #1
must be set to low speed and jets pump #2 must be turned off to operate
the heater.
For Export spas connected to a 20 amp service, jets pump #1 must be set
to low speed and jets pump #2 must be turned off to operate the heater.
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 tempera-
ture”, 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 operating costs.
The time required for initial heat-up will vary depending on the starting
water temperature.
DANGER: Risk of injury, always check water temperature carefully
before entering spa!
Decontamination Procedure (Steps 9-16)
Steps 9-16 below are only required when sanitizer levels are unstable after
performing steps 1-6 above. Disregard steps 9-16 below if sanitizer levels
remain stable at 3.0-4.0 ppm chlorine or 2.0-4.0 ppm bromine after performing
steps 1-6.
9. Add 2.5 ounces of sodium dichlor for every 100 gallons of water. Refer to
the table below for approximate water fill volume by model.
CAUTION: Never add chlorine tablets (trichlor) to your spa for any
reason! This chemical may damage your spa and void the manufac-
turer warranty.
