LED Series Owner’s Manual

Attention New Spa Owner!
Congratulations on the purchase of your new Jacuzzi Premium spa!
Listed below are important maintenance recommendations you
should observe on a regular basis to protect your new investment.
Filter Maintenance
Your new spa is equipped with an advanced 2-stage water filtration
system that provides unsurpassed water quality! To ensure maxi-
mum water quality at all times, you should clean and reuse the
skimmer bag and both filter cartridges every month. See page 30-
31 for detailed filter cleaning/replacement 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 mainte-
nance, 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 measure-
ments are all within the proper parameters. See page 35 for addi-
tional 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).

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 provided on the
surface of the control box, located outside the equipment door (Figure B, Page
11) 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 installation conforms to local building
codes.
Page 5

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
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
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.
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 require-
ments, damage to the skirt and/or the spa shell may result. Damage
caused by improper support is not covered under warranty. It is the respon-
sibility of the spa owner to assure the integrity of the support over time.
We recommend a poured, reinforced concrete slab with a minimum thick-
ness 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 equip-
ment, 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).
Page 6

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.

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 half way 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 sec-
tion 11.1 (Page 30) “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.
7.3Turn on Power
Turn on power to spa at the home’s circuit breaker. The heater and low speed
pump 1 automatically activate and the control panel LED display flashes water
temperature and “COL” or “ICE” (page 38).
7.4Initiate Water Circulation
Depress the JETS 1 sensor pad on the control panel twice to activate
pump 1 in high speed and initiate maximum water flow to certain jets.
7.5 Add Start-Up Chemicals
Add the spa water chemicals as recommended by your Jacuzzi Premium
dealer. Refer to section 12.2 (page 36) 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 (based on 240V operation); large
spas heat at about 4 to 6 degrees per hour.
WARNING: RISK OF INJURY. Always check water temperature
carefully before entering spa.
