grounding type receptacle only.
** For units with GFCI: Warning – This product is provided with a ground-
fault circuit interrupter located in the main panel. The GFCI must be tested
before each spa use.
DANGERS
RISK OF ACCIDENTAL DROWNING: Extreme caution must be
exercised to prevent unauthorized access by children. To avoid
accidents, ensure that children cannot use this spa unless they are
supervised at all times. Always cover the hot tub and use safety
locks when it is not in use.
RISK OF INJURY: The suction fittings in this spa are sized to match
the specific water flow created by the pump. Should the need arise
to replace the suction fittings or the pump, be sure that the flow rates
are compatible. Never operate the spa if the suction fittings are
broken or missing. Never replace a suction fitting with one rated less
than the flow rate marked on the original suction fitting.
RISK OF ELECTRIC SHOCK: Install at least 5 feet (1.5 m) 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 by a minimum 8 AWG (8.4 mm2) solid copper conductor
to the wire connector on the terminal box that is provided for this
purpose.
RISK OF ELECTRIC SHOCK: Do not permit any electric appliance,
such as a light, telephone, radio or television, within 5 feet (1.5 m) of
a spa. Do not operate such an appliance from either inside the hot
tub or when you are wet, unless such appliances are built-in by the
manufacturer.

WARNINGS
TO REDUCE THE RISK OF INJURY:
The water in a spa should never exceed 40˚C (104˚F).
Water temperatures between 38˚C (100˚F) and 40˚C
(104˚F) are considered safe for a healthy adult. Lower
water temperatures are recommended for young children
and when spa use exceeds 10 minutes.
Since excessive water temperatures have a high potential
for causing fetal damage during the early months of
pregnancy, pregnant or possible pregnant women should
limit spa water temperatures to 38˚C (100˚F).
Before entering a spa/hot tub, the user should measure the
water temperature since the tolerance of water temperature
regulating devices varies.
The use of alcohol, drugs or medication before or during
spa/hot tub use may lead to unconsciousness with the
possibility of drowning.
Obese persons and persons with a history of heart disease,
low or high blood pressure, circulatory system problems, or
diabetes should consult a physician before using a spa.
Persons using medication should consult a physician before
using a spa/hot tub since some medication may include
drowsiness while other medication may affect heart rate,
blood pressure and circulation.
Do not connect auxiliary components (such as headphones, cables,
and additional speakers) to the stereo (if equipped).
Do not use a hot tub immediately following strenuous exercise.
Do not use your hot tub alone.
Lock the cover on your hot tub when not in use.
Persons with infectious diseases should not use a hot tub.
Replace audio components only with identical components.
Do not leave the CD access door open on the stereo (if equipped).
Some types of hair dye can react with the sanitizers in your hot tub
water causing your hair to change color. Use at your own risk.
Water normally splashes out of a hot tub during typical use. Install
an adequate perimeter that provides sound footing.
Do not turn your hot tub on/off from a wall switch, ground fault circuit
interrupter, circuit breaker, fuse, or by plugging/unplugging it.
Remove all jewelry, metal, and watches from your person before
entering your hot tub.
Keep all breakables away from the hot tub area.
Maintain water balance in accordance with instructions.

WARNING SIGN
Warning Sign Must Be Posted – The red
WARNING sign like the one shown is packed
with your new hot tub. This sign must be posted
in a prominent place in close proximity to the hot
tub installation site immediately upon completion
of hot tub installation.
Important: It is extremely important that this sign be permanently placed in clear
view of persons using the hot tub. Occasional hot tub users may not be aware of
some of the dangers hot water poses to pregnant women, small children,
seniors, and people under the influence of alcohol. If you did not receive a
warning sign or your sign has become damaged, please call your local dealer for
a replacement.
HYPERTHERMIA
To reduce the risk of injury, the water temperature in a 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, senior citizens, persons with sensitivities, and
when hot tub use exceeds 10 minutes.
WATER TEMPERATURE IN EXCESS OF 100˚F (38˚C) MAY BE INJURIOUS
TO YOUR HEALTH.
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:
Unawareness of impending hazard
Failure to perceive heat
Failure to recognize the need to exit hot tub
Physical inability to exit hot tub
Fetal damage in pregnant women
Unconsciousness and danger of drowning
If you sense any of the symptoms of hyperthermia, safely exit the hot tub
immediately.

Location and Installation
Proper planning is an important consideration when installing your new
hot tub. Site selection is a critical step and requires serious thought.
Planning ahead makes the installation process easier. The following
information is provided to assist you in site preparations.
1) Always comply with local building codes and obtain any necessary
permits. You may also need to consult with an engineer to address
your specific design needs.
2) Contact an electrician to assess your electrical needs, install wiring,
and assure a safe operation.
3) Position your hot tub with proper access to water, drainage, and
electricity.
4) Place your hot tub on a uniform solid, flat surface designed to
properly support its weight. For external installations, a 4-inch (10
cm) thick cement pad suffices. See page 8 for conduit entry locations
for your model hot tub.
5) For internal installations, check the load carrying capabilities of the
floor on which the hot tub will reside. Most homes meet the
requirement of 80 pounds per square foot.
6) Assure that your hot tub will fit into the space you have chosen and
the delivery route will accommodate its large size.
7) Provide adequate ventilation for the humidity created by your hot tub.
In most cases, a Hot Tub Hard Cover is sufficient.
8) Protect the pump and all equipment from the weather by ensuring
the cabinet panels are secure at all times.
9) Allow 36 inches (1 meter) of unobstructed access to all sides of your
hot tub for normal servicing. Your hot tub is not designed to be
recessed in the ground or in a deck.

10) Consider positioning your hot tub out of or adequately protecting it
from the wind. Just as people can get cold on cool/windy days so
can your hot tub. Windy environments can significantly increase
operating costs.
11) Consider using an insulating pad. In cold climates, the ground can
rob heat from the hot tub and increase your operating costs. Consider
using a suitable, outdoor insulating pad in such environments.

WARNING: Disconnect the electrical power before servicing. Before
obtaining access to terminals, all supply circuits must be
disconnected.
Caution: Test the GFCI (or RCD) before each use.
Our hot tubs are certified by Intertek Testing, SNAa Ltd.
Ontario, Canada to CSA-C22.2 No. 218.1-M89 and
ANSI/UL 1563 standards.
Parts with extra low voltage not exceeding 12v must be inaccessible to a
person in the hot tub. Earthed appliances must be permanently
connected to fixed wiring. Parts incorporating electrical components,
except remote control devices, must be located or fixed so that they
cannot fall into the hot tub.
Means for disconnection must be used in fixed wiring in accordance with
wiring rules.
Important – To allow the 240V GFCI to function properly, connect the
white Neutral wire from the hot tub to the Neutral terminal on the GFCI
breaker, not the Neutral bus in the GFCI breaker box. An improperly
connected Neutral causes the GFCI breaker to trip.
