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
as dened 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
!TO DECREASE RISK OF INFECTION OR DISEASE! Always maintain
your spas lter as outlined below to ensure healthy spa water. Refer page 36
“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 30 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 36 for additional information.

1.0 Important Spa Owner Information
Your Jacuzzi® J-300 Series 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 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 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).

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 minimum No. 8
AWG (8.4 mm²) solid copper conductor attached to the wire connector

fetal damage during the early months of pregnancy, if pregnant or
possibly pregnant, consult your physician before using a spa.
Pregnant or possibly pregnant women should limit spa water •
temperatures to 100°F (38°C).
Persons suffering from obesity or a medical history of heart disease, •
low or high blood pressure, circulatory system problems, diabetes,
infectious diseases or immune deciency syndromes should consult a
physician before using a spa.
If you experience breathing difculties in association with using or •
operating your spa, discontinue use and consult your physician.
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.
Persons suffering from any condition requiring medical treatment, the •
elderly, or infants should consult with a physician before using a spa.
The use of alcohol, drugs, or medication before or during spa use may •
lead to unconsciousness with the possibility of drowning.
7. !WARNING: RISK OF SEVERE INJURY OR DEATH!
Prolonged immersion in a spa may be injurious to your health.•
Observe a reasonable time limit when using the spa. Exposures at •
higher temperatures can cause high body temperature (over-heating).
Symptoms may include dizziness, nausea, fainting, drowsiness, and
reduced awareness. These effects could possibly result in drowning or
serious injury.
Never use a spa immediately following strenuous exercise. Enter and •
exit the spa slowly. Wet surfaces can be slippery.
8. !WARNING: TO DECREASE RISK OF INFECTION OR
DISEASE!
To reduce the risk of• contracting a waterborne illness (e.g. an infection,
bacteria or virus) and/or respiratory ailments , maintain water chemistry
within the parameters listed on the inside cover of this manual and
consult with a licensed engineer regarding proper ventilation if installed
indoors or in an enclosed area.
People with infectious diseases should not use a spa to avoid water •
contamination, which could result in spreading infections to others.
Always shower before and after using your spa. Maintain water chem-•
istry in accordance with manufacturer’s instructions. Failure to do
so may result in contracting a waterborne illness (e.g. an infection,
bacteria or virus).
