Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS.
WARNING:
To reduce the risk of injury, do not permit children to
use this product unless they are closely supervised
at all times.
DANGER -- Risk of accidental drowning:
Do not allow children to be in or around a spa unless
a responsible adult supervises them. Keep the spa
cover on and locked when not in use. See instructions
enclosed with your cover for locking procedures.
DANGER -- Risk of injury:
The suction  ttings in this spa are sized to match
the speci c water fl ow created by the pump. Should
the need arise to replace the suction  ttings, or the
pump, be sure the fl ow rates are compatible.
Never operate the spa if the suction  tting or  lter
baskets are broken or missing. Never replace a
suction  tting with one that is rated less than the fl ow
rate marked on the original suction  tting.
DANGER -- Risk of electric shock:
Install the spa at least 5 feet (1.5 meters) from all
metal surfaces. As an alternative, a spa may be
installed within 5 feet of metal surfaces if each metal
surface is permanently bonded by a minimum #8
AWG solid copper conductor to the outside of the
spa’s control box.
DANGER -- Risk of electric shock:
Do not permit any external electrical appliances,
such as lights, telephones, radios, televisions, and
etc., within  ve feet (1.5 meters) of the spa. Never
attempt to operate any electrical device from inside
the spa.
HYPERTHERMIA DANGER:
Prolonged exposure to hot air or water can induce
hyperthermia. Hyperthermia occurs when the internal
temperature of the body reaches a level 3˚F to 6˚F
above the normal body temperature of 98.6˚F (or
2˚C to 4˚C above 37˚C). While hyperthermia has
many health bene ts, it is important not to allow
your body’s core temperature to rise above 103˚F
(39.5˚C).
Symptoms of excessive hyperthermia include
dizziness, lethargy, drowsiness and fainting. The
effects of excessive hyperthermia may include:
Failure to perceive heat•
Failure to recognize the need to exit spa or hot•
tub
Unawareness of impending hazard•
Fetal damage in pregnant women•
Physical inability to exit the spa•
Unconsciousness•
WARNING: The use of alcohol, drugs, or medication
can greatly increase the risk of fatal hyperthermia.
WARNING -- To reduce the risk of injury:
The spa water 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 and when spa use exceeds 10
minutes.
High water temperatures have a high potential for
causing fetal damage during pregnancy. Women who
are pregnant, or who think they are pregnant, should
always check with their physician prior to spa usage.
The use of alcohol, drugs or medication before or
during spa use may lead to unconsciousness, with
the possibility of drowning.
Persons suffering from obesity, a medical history of
heart disease, low or high blood pressure, circulatory
system problems or diabetes should consult a
physician before using the spa.
Persons using medications should consult a physician
before using the spa since some medications may
induce drowsiness while others may affect heart rate,
blood pressure and circulation.

Most cities and counties require permits for exterior construction and electrical circuits. In addition, some
communities have codes requiring residential barriers such as fencing and/or self-closing gates on property to
prevent unsupervised access to the property by children. Your dealer can provide information on which permits
may be required and how to obtain them prior to the delivery of your spa.
Before Delivery
Plan your delivery route
Choose a suitable location for the spa
Lay a 5 - 8 cm concrete slab
Install dedicated electrical supply
After Delivery
Place spa on slab
Connect electrical components
Preparing for Your New Portable Spa
Planning the Best Location
Safety First
Do not place your spa within 10 feet (3 m) of
overhead power lines.
Consider How You Will Use Your Spa
How you intend to use your spa will help you
determine where you should position it. For example,
will you use your spa for recreational or therapeutic
purposes? If your spa is mainly used for family
recreation, be sure to leave plenty of room around
it for activity. If you will use it for relaxation and
therapy, you will probably want to create a speci c
mood around it.
Plan for Your Environment
If you live in a region where it snows in the winter or
rains frequently, place the spa near a house entry. By
doing this, you will have a place to change clothes
and not be uncomfortable.
Consider Your Privacy
In a cold-weather climate, bare trees won’t provide
much privacy. Think of your spa’s surroundings during
all seasons to determine your best privacy options.
Consider the view of your neighbors as well when
you plan the location of your spa.
Provide a View with Your Spa
Think about the direction you will be facing when
sitting in your spa. Do you have a special landscaped
area in your yard that you  nd enjoyable? Perhaps
there is an area that catches a soothing breeze during
the day or a lovely sunset in the evening.
Keep Your Spa Clean
In planning your spa’s location, consider a location
where the path to and from the house can be kept
clean and free of debris.
Prevent dirt and contaminants from being tracked
into your spa by placing a foot mat at the spa’s
entrance where the bathers can clean their feet
before entering your spa.
Allow for Service Access
Make sure the spa is positioned so that access to the
equipment compartment and all side panels will not
be blocked.
Many people choose to install a decorative structure
around their spa. If you are installing your spa with
any type of structure on the outside, such as a
gazebo, remember to allow access for service. It is
always best to design special installations so that the
spa can still be moved, or lifted off the ground.

Preparing a Good Foundation
Your spa needs a solid and level foundation. The
area that it sits on must be able to support the weight
of the spa, with water and the occupants who use it.
If the foundation is inadequate, it may shift or settle
after the spa is in place, causing stress that could
DAMAGE YOUR SPA SHELL AND FINISH.
Damage caused by inadequate or improper
foundation support is not covered by the
warranty. It is the responsibility of the spa
owner to provide a proper foundation for
the spa.
Place the spa on an elevated 3 to 4” / 30 cm concrete
slab. Pavers, gravel, brick, sand, timbers or dirt
foundations are not adequate to support the spa.
We strongly recommend that a quali ed, licensed
contractor prepare the foundation for your spa.
If you are installing the spa indoors, pay close
attention to the fl ooring beneath it. Choose fl ooring
that will not be damaged or stained.
If you are installing your spa on an elevated wood
deck or other structure, it is highly recommended
that you consult a structural engineer or contractor
to ensure the structure will support the weight of 150
pounds per square foot (732 kg / m2).
To properly identify the weight of your new spa when
full, remember water weighs 8.33 lbs. per gallon, or 1
kg per liter. For example, an average 8’ spa spa holds
approximately 500 gallons, or 1892 liters, of water.
Using this formula, you will fi nd that the weight of the
water alone is 4,165 lbs, or 1892 kg. Combined with
the dry weight of the spa you will note that this spa
will weigh approximately 5,000 lbs, or 2267 kg, when
full of water.

All 240V spas must be permanently connected
(hardwired) to the power supply. See the wiring
diagram on page 7.
These instructions describe the only acceptable
electrical wiring procedure. Spas wired in any
other way will void your warranty and may
result in serious injury.
When installed in the United States, the electrical
wiring of this spa must meet the requirements of
NEC 70 and any applicable local, state, and federal
codes.
The electrical circuit must be installed by an
electrical contractor and approved by a local
building or electrical inspector.
Failure to comply with state and local codes
may result in  re or personal injury and will be
the sole responsibility of the spa owner.
The power supplied to the spa must be on a dedicated
GFCI protected circuit as required by NEC 70 with no
other appliances or lights sharing the power.
Use copper wire with THHN insulation. Do not use
aluminum wire.
Use the table below to determine your GFCI and
wiring requirements.
Wire runs over 85 feet must increase wire gauge
to the next lower number. For example: A normal
50 amp GFCI with four #8 AWG copper wires run
over 85 feet would require you to go to four #6 AWG
copper wires.
240 Volt Electrical Installation
240V GFCI and Wiring Requirements
All VS500 control systems are set at the factory to run on the low power setting for low amperage operation.
This is the default setting. Spa owners can have their installer change this setting so the spa will run on high
power for 50 or 60 amp operation.
Warning: Never set a spa to run on high power without installing a properly rated GFCI.

Filling and Powering Up Your Portable Spa
Inspect the spa equipment.1.
Fill the spa.3.
Neverllyourspawithsoftwater.
Soft water makes it impossible to maintain
the proper water chemistry and may cause
the water to foam, which will ultimately
harm the  nish of the spa and void your
warranty.
Remove the cartridge from  lter canister.2.
Place a garden hose in the fi lter canister and fi ll your spa
with regular tap water about six inches from the top.
If the water level is too low or too high, your spa will not
operate properly.
Always fi ll the spa through the fi lter canister! Failure
to do so may cause air to be trapped in the fi ltration
system and prevent the pumps from operating
properly.
Unscrew the cartridge and remove it.
After you remove the fi lter, remove the plastic wrapper
and soak it in water for 30 minutes before you replace
it. A dry fi lter can allow air into the fi ltration system
which can cause the pump to fail to prime.
After the spa has been placed on an approved surface and
has been correctly wired by a licensed electrician, inspect
all plumbing connections in the equipment area of your spa.
Ensure that these connections are secure and that they did
not loosen during shipment.
If your spa has gate valves, make sure they are all in the
UP or OPEN position.
Never run the spa with the gate valves closed or without
water circulating for long periods of time. Be careful not to
over-tighten the plumbing  ttings.

Let the spa heat up.7.
When the spa has  nished priming, the heater will activate.
Put the cover on and let the spa run for two hours.
Adjust water chemistry.8.
After the spa has run for two hours, test and adjust the water chemistry. See the section on page 18 for
instructions on water clarity.
When the spa is  lled to the correct level, turn on the
power at the GFCI breaker. (Ensure that the 120V spas are
connected to the proper electrical outlet.)
If spa fails to prime, there could be an air pocket at the suction side of the pump. Follow the priming instructions
on page 10 using the bleeder valve.

Priming the Pump
New spa owners often have dif culty the  rst time they
start their spa and the pump fails to prime. This can be
frustrating, but these simple instructions can help you.
Sometimes air can become trapped in the pump while  lling the spa. You will know this has happened when
after you have  lled and started the spa, the pump does not seem to function. You will hear the pump
operating, but no water will be moving.
There are two methods of priming the pump.
Using the bleeder valve:
Using the control panel:
Turn the spa on and wait for PR (Priming Mode)1.
to appear on the topside display.
Press the JETS button to turn on the pump and2.

Low and High Power Operation
Two and three pump systems can be confi gured to
operate on low or high power. The factory default
is low power. This section describes how the
spa operates when it is confi gured for low power
operation.
See page 5 for GFCI and wiring requirements for
both low and high power operation.
Spas con gured for low power operation require
approximately 20% less power to operate. With low
power con guration, the spa will never use more
than 30 amps while in operation and will alternate
between 110V and 220V, while spas con gured for
high power will operate continuously at 220V.
When only one pump is running, the heater will
operate at 220V. When two or three pumps are
running, the heater will automatically switch to op-
erate at 110V.
The heater light will tell you when it is operating
and what voltage it is using. See the “Heater Light”
section above.
For spas con gured for high power operation, the
heater will turn on when (1) the water temperature
drops or (2) the jets are in use.

Freeze Protection
If the temperature sensors detect a drop to 44°F
within the heater, the pump automatically activates
to provide freeze protection. The equipment stays
on until four minutes after the sensors detect that
the spa temperature has risen to 45°F or higher.
In colder climates, an optional additional freeze
sensor may be added to protect against freeze
conditions that may not be sensed by the standard
sensors. Auxiliary freeze sensor protection acts
similarly except with the temperature thresholds
determined by the switch and without a four-
minute delay in turnoff.
Setting Filtration Cycles
Your spa is programmed to  lter twice a day. The
 rst cycle will begin 6 minutes after the spa is turned
on and the second cycle 12 hours later. The factory
has programmed the cycle to last for 2 hours but
this can be switched to your preference.
To set time the  ltration cycle begins, turn off the
power to the spa at the time of day you would
like one of the  ltration cycles to begin then turn
back on after 30 seconds. When power has been
restored, press the Temp UP or the Temp DOWN
button, followed by the Jets button. Press Temp
UP or Temp DOWN again to change the  ltering
cycle duration.
The  ltration cycles and their displays are as

Electrical Power Ef ciency
Your new spa comes equipped with an electric heater.
Following the directions listed below will ensure the
most ef cient operation:
NOTE: This method is only for spa usage under two
hours a week.
Keep the spa’s operating temperature 5˚F below •
the desired usage temperature when not in use.
One or two hours before use, set the temperature
to the desired temperature.
If the spa usage exceeds two hours a week, the•
set temperature should remain at the desired
usage temperature.
Allowing the water temperature to lower more than
10˚F below the desired usage temperature and
reheating it prior to usage will cause the heater to
operate longer than it normally would maintaining
the desired temperature. Doing this will increase your
operating cost and makes your heater work more
than necessary.
Light
Press the Light button to turn on the
light. Press it once again to turn the light
off. All optional lighting such as the control
panel light and cabinet perimeter lighting
is controlled by the Light button and will
turn on and off with the spa light.

Jets
Almost all of the jets in your spa are adjustable.
Rotating the face of an adjustable jet to the left
(counter-clockwise) will decrease the amount of
water fl ow through the jet. Rotating the face of an
adjustable jet to the right (clockwise) will increase
the amount of water fl ow through the jet. (See
example shown below.)
Neck jets adjust in the opposite directions (counter-
clockwise to increase, clockwise to decrease).
Diverter Knobs
Diverter knobs are 1” and 2” knobs located around
the top of your spa. They allow you to divert water
through jets from one side of the spa to the other,
or in most cases from fl oor jets to wall jets. This is
accomplished by rotating the diverter knob to the
left (counterclockwise), decreasing the amount of
water fl ow through a section of jets. To increase
the amount of water fl ow through the other section
of jets, rotate the handle to the right (clockwise).
Hydro Streamer Waterfall
Your spa includes six or eight streamer waterfalls. When the booster pump is on, turn the 1” diverter knob.
The waterfall jets will start immediately.
The waterfall jets are not adjustable. Do not turn the jet faces because you may accidentally remove them.
Always shut off water to the hydro streamer
jets before you place the cover on the
spa. Water from the hydro streamer
jets sprays in an arc that
is higher than the top
surface of the spa.
When water from the
hydro streamer sprays
the bottom of the cover,
it will collect and run to
the edge of the spa and
drip over the top.

Your Key
To Clear
Water
Clear Water Plan
This section is intended for new spa owners with
no experience with water chemistry. Everyone’s ex-
perience with maintaining water quality is different,
but there are some general concepts you need to
know.
Water maintenance is not dif cult, although it re-
quires regular attention. The most important thing
to understand about taking care of your spa water is
that preventive action is much easier than correcting
water quality issues.
Regularity
Clear water requires regular maintenance.
Establish a routine based on a regular
schedule for your spa water maintenance.
Maintaining your water quality helps the en-
joyment of your spa and extends your spa’s
life by preventing damage from neglect and
chemical abuse.
See page 24 for the sched-
ule of recommended main-
tenance.
Sanitation
Sanitizers kill bacteria and
viruses and keep the water
clean. A low sanitizer level
will allow microbes to grow
quickly in the spa water.
We recommend using either chlorine or
bromine as your sanitizer.
See page 20 for learn how to use sanitizer.
Filtration
Cleaning your fi lter regularly is the easiest
and most effective single thing you can do
to keep your water clear.
A clogged or dirty fi lter will cause the heater
and pump to work harder than they need
to, possibly causing them to fail.
The spa’s heating system will only function
with the proper amount
of water fl ow through the
system.
See page 22 for fi lter
cleaning instructions.
Chemical Balance
You will need to test and
adjust the chemical balance
of your spa water. Although
this is not diffi cult, it needs
to be done regularly.
Depending on your choice of sanitizer, you
need to test the level of calcium hardness,
total alkalinity, and pH.
See page 20 for learn how to balance your
spa water.
