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 rst 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 rst ltration/
heating cycle turns on pump 1. 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:
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 maintain
your spas lter as outlined below to ensure healthy spa water. Refer page 39
“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 both lter cartridges every month, or earlier as necessary. See page
33 for detailed lter cartridge cleaning/replacement instructions.
Required Water Replacement
!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 page 39 for additional information.

1.0 Important Spa Owner Information
Your Jacuzzi J-300 Collection 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
efcient operation, an uncovered spa surface and wall ttings directly
exposed to sunlight and high temperatures for an extended period are
subject to permanent damage. 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 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 9).
Jacuzzi constantly strives to offer the nest spas available,
therefore modications and enhancements may be made which
affect the specications, illustrations and/or instructions contained
herein.

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. !DANGER: RISK OF SEVERE INJURY FROM ELECTRIC
SHOCK OR DEATH FROM ELECTROCUTION!
• Install the spa 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

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

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.
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 dependable 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 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
insure installation conforms to local building codes.

J-300
4.0 Choosing A Location
WARNING: For spas that are to rest on balconies, roofs
or other platforms not specically tied into main struc-
tural 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 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 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.
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 deck-
ing is also acceptable provided it is constructed so that it meets the
requirements outlined above.
!

J-300
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.
• 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.
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, bac-
teria or virus) and/or respiratory ailments that could be pres-
ent 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 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 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 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 which can damage certain surfaces and/
or surroundings.
• Sufcient 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 to local codes or authorities is
not covered under the spas warranty. Please consult your local state
or city building ordinances.
5.0 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 equipment 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 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 this spa, check with the local building department to
insure installation conforms to local building codes.

120/240 Volt 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 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.
6.0 Power Requirements
Jacuzzi spas are designed to provide optimum
performance and exibility of use when connected to the
maximum electrical service listed below. Minor circuit
board modications can be performed to allow your new
