1.0 Important Hot tub Owner Information
Your hot tub is constructed to the highest standards and is capable of
providing many years of trouble-free use. However, because heat reten-
tivematerialsareutilizedtoinsulatethehottubforefcientoperation,an
uncoveredhottubsurfaceandwallttingsdirectlyexposedtosunlightand
high temperatures for an extended period are subject to permanent dam-
age or discoloration. Damage caused by exposing the hot tub to this abuse
is not covered under warranty. We recommend that you always keep the
hot tub full of water when it is exposed to direct sunlight and that you keep
the insulating cover in place at all times when the hot tub is not in use.
Read and carefully follow the requirements for your hot tub’s support base
found in the Section 4.0 titled, “Choosing a Location” (page 9).
2.0 FCC Notice
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for
a Class B Digital Device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will
not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
1. Rearrange or relocate the receiving antenna;
2. Increase the separation between the equipment and receiver;
3. Connect the equipment into an outlet on a circuit different from the
circuit connected;
4. Consult the dealer or an experienced radio/TV technician for help.
(Changesormodicationsnotexpresslyapprovedbytheparty
responsible for FCC compliance could void the user’s authority to

3.0 IMPORTANT SAFETY INSTRUCTIONS
FOR ALL HOT TUB OWNERS

CAREFULLY!
Thishottub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 hot tub, 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 hot tub
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 hot tub cover when
not in use. This will help discourage unsupervised children from
entering the hot tub. Keep the hot tub cover secure in high-wind
conditions.
• There is no representation that the cover, clip tie-downs, or actual
locks will prevent access to the hot tub.
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hottubunlessallsuctionguards,lter,lterlid,
or skimmer assembly are installed to prevent body and/or hair
entrapment.
• Neveroperateorusethehottubifthelter,lterlid,orskimmer
assembly are broken or any part of the skimmer assembly is missing.

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 hot tub at least 5 feet (1.5m), from all metal surfaces.
As an alternative, a hot tub 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 on the grounding lug, inside the equipment
compartment on the equipment box.
• A grounding wire connector is provided on this unit to connect a
minimum No. 8 AWG (8.4 mm²) solid copper conductor between
this unit and any metal equipment, metal enclosures of electrical
equipment, metal water pipe, or conduit within 5 feet (1.5m) of the unit.
• Never permit any electrical appliance, such as a light, telephone,
radio, television, etc. within 5 feet (1.5m) of a hot tub unless such
appliances are built-in by the manufacturer.
• Never bring any electrical appliances into or near the hot tub.
• Never operate any electrical appliances from inside the hot tub or
when you are wet.
• 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/USA,
ANSI/NFPA 70. The disconnecting means must be readily accessible
and visible to the hot tub occupant but installed at least 5 feet (1.5m),
from the hot tub.
• The electrical circuit supplied for the hot tub must include a suitable
ground fault circuit interrupter (GFCI) as required by NEC Article 680-42.
4. !WARNING:RISK OF SEVERE INJURY OR DEATH!

5. !WARNING:RISK OF HYPERTHERMIA (OVER-HEAT-
ING) CAUSING SEVERE INJURY, BURNS, WELTS OR DEATH!
• Water temperature in excess of 104°F (40°C) may be injurious to

• RefertoSection3.2Hyperthermiaforspeciccausesandsymptoms
of this condition.
• The water in the hot tub should never exceed 104°F (40°C).
Water temperatures 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
(children are especially sensitive to hot water) and when hot tub use
may exceed 10 minutes.
• The Consumer Products Safety Commission/USA has stated that the
water temperature in a hot tub should not exceed 104°F (40°C).
• Always test the hot tub water temperature before entering the
hot tub. 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).

6. !WARNING:RISK OF SEVERE INJURY OR DEATH!
• Since excessive water temperatures have a high potential for causing
fetal damage during the early months of pregnancy, if pregnant or
possibly pregnant, consult your physician before using a hot tub.
• Pregnant or possibly pregnant women should limit hot tub water
temperatures to 100°F (38°C).

may lead to unconsciousness with the possibility of drowning.
7. !WARNING:RISK OF SEVERE INJURY OR DEATH!
• Prolonged immersion in a hot tub may be injurious to your health.
• Observe a reasonable time limit when using the hot tub. 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 hot tub immediately following strenuous exercise. Enter
and exit the hot tub 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 hot tub to avoid
water contamination, which could result in spreading infections to
others.
• Always shower before and after using your hot tub. Maintain water
chemistry in accordance with manufacturer’s instructions. Failure to
do so may result in contracting a waterborne illness (e.g. an infection,
bacteria or virus).
