lethargy, drowsiness, and fainting. The eects
of hyperthermia include:
a. Failure to perceive heat
b. Failure to recognize the need to exit spa
or hot tub
c. Unawareness of impending hazard
d. Fetal damage in pregnant women
e. Physical inability to exit the spa or hot
tub, and
f. Unconsciousness resulting in the danger
of drowning.
WARNING  The use of alcohol, drugs,
or medication can greatly increase the
risk of fatal hyperthermia.

6 VITA SPA DUET
SPA INSTALLATION
Danger: Electrical shock risk. Install at
least 1.5m from all metal surfaces.
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 ANSI/NFPA70-
2008. The disconnecting means must be
readily accessible but installed at least 6 feet
(1.8 meters) from the spa water. All electrical
connections should comply with article 680-IV
of the NEC.
Site and Positioning
Locate the spa on solid, level foundation or
ooring, keeping in mind the weight of the
lled spa [in excess of
4,000 bls. (1.800 kg.) on
some models]. If you have any doubts about
the load bearing ability of your chosen site,
contact an architect or a building contractor.
The entire perimeter of the spa cabinet and
the spa bottom must be evenly supported.
If your spa is installed outdoors, we
recommend that you provide a concrete pad
for the spa to rest on 8ft x 8ft x 4in (2,5m x
2,5m x 10cm level pad). Failure to provide
a at level surface could structurally
damage your spa and void the warranty.
The spa must be installed to allow access for
service and maintenance on all four sides;
therefore, below grade level installation is
not recommended.
Outdoor Installation
The following considerations apply when
installing your spa outdoors:
1. Local codes pertaining to fencing.
2. Local electrical and plumbing codes.
3. View from your house.
4. Wind direction.
5. Exposure to sunlight.
6. Location relationship to trees (twigs,
leaves and shade).
7. Dressing and bathroom location.
8. Storage area for maintenance equipment
and chemicals.
9. Location to facilitate adult supervision.
10. Landscaping and nighttime lighting.
11. Accessibility to equipment.
12. Power supply location and foot trac.
Indoor Installation
The following considerations apply when
installing your spa indoors:
1. Indoor spas promote high humidity. Using
either ventilation fans or commercial
grade de-humidiers will help to reduce
the humidity. Consult your dealer for
details.
2. Floor drains must be provided near the
spa to drain o water that may cause
falls and /or water damage.
3. Floor area should be at with a non-skid
nish. Carpeting is not recommended.
4. Walls, ceilings, woodwork should be made
of materials capable of withstanding high
humidity (redwood, cedar).
5. Be sure oor load bearing capacities are
adequate to support the concentrated
spa weight.
6. Spas should be double checked for leaks
before installing to avoid possible water
damage. Dealer installation may include
this service.

7 VITA SPA DUET
7. Indoor sun rooms are capable of
maintaining high ambient temperatures
which may eect the spa water
temperature. It is NOT recommended
that you operate your lter cycles for

JETS, AIR CONTROLS & VALVES
Jets
All spa jets are individually engineered
to provide a unique hydro-massage.
Depending on the model, your spa will have
a combination of the following jets:
Directional Therapeutic
(200, 300, and 400 Series Wave Style):
Positioned to focus on large muscle groups,
these jets deliver a concentrated, high
volume stream of water for a deep massage.
Each jet is fully adjustable, allowing users to
set the water ow to the most comfortable
setting. The nozzle can be rotated to target
sore muscle areas.
Rotational or Spinning Jets
(200, 300, and 400 Series Wave Style):
Positioned to focus on muscle tension
zones, these jets deliver a spinning water
stream for a gentle, pulsating massage.
Each jet is fully adjustable, allowing users to
set the water ow to the most comfortable
setting.
Swim Jet( non-adjustable):
Positioned to create overall water
circulation, this multi-purpose, high volume
jet provides whirlpool action throughout
the entire spa.
Euro Jets:
Positioned in the foot well or shoulder areas
of the spa, these jets deliver a penetrating
massage to dissolve tension. This jet may be
the entry point for ozone produced during
the automatic ltration cycles, and, as such,
is not adjustable.
Note: Ozone production is activated when
the low speed pump is activated.
Many full sized jets are adjustable from a fully
open to closed position. It is very important
that you NEVER SHUT ALL FULL SIZED JETS
OFF AT ONE TIME! WHEN EXITING THE SPA,
OPEN ALL CLOSED JETS.
Cleaning or Replacing Jets
Hard water can cause calcium/mineral
buildup that can restrict or bind the jets. A jet
consists of a face plate and a nozzle. Rotate
these parts weekly and remove/clean monthly
to ensure free movement.
NOTE: It is not necessary to drain the spa to
clean or remove the jets.
Rotating the jet face plate and nozzle
• Rotate the jet face left and right
(open and closed).
• Return the face plate to the full open
position.
• Turn the jets on to high speed.
• Twist the nozzle left and right.
• Rotate the nozzle in the socket.
NOTE: If the jet insert disengages from the
spa housing, see steps to reinstall below.
Cleaning the jets
To remove the jet insert, use the palm of your
hand to exert pressure on the face of the jet.
Turn counterclockwise until the jet ‘clicks’.
Gently pull the jet assembly from the housing.

11 VITA SPA DUET
To clean the jet insert and housing, use a
pressurized hose and spray the inside of
the jet housing. Soak the jet in a diluted spa
cleaning solution, rinse. Wipe the inside of the
housing to remove any debris.
To reinstall the jet, line up the tab on the
backside of the barrel with the groove in the
body. Use the palm of your hand to gently tap
the jet until it snaps into position.
Air Control
The intensity of the jet action can be
controlled by altering the amount of air
injected with water through the jets. Your
spa has 1 air control located on the lip of
the spa. Each control activates air to specic
jets in the spa allowing you to create various
combinations and levels of jet action to
suit individual preferences. Turn the control
counter- clockwise to turn the air o and
clockwise to turn air on.
NOTE: Air controls should be closed
during heating cycles for maximum
energy eciency.
Diverter Valve: Diverts water from one set
of jets to another. The diverter valve should
be tested weekly to clean the lines and to
help prevent debris from building up.
NOTE: The diverter valve should be cleaned
regurally. Remove the handle by pulling
upward and rocking it back and forth,
unscrew the cap and pull the valve stem out.
To clean the valve stem and housing, use a
pressurized hose and spray the inside of the
valve housing. Soak the valve stem in a diluted
spa cleaning solution, rinse. Wipe the inside of
the housing to remove any debris.

This equipment is designed to operate on
60Hz alternating current only, at 120 volts.
NOTE: All unions must be hand-tight and
all slice valves must be locked in the OPEN
position before lling or relling spa!
A clip is provided to help keep the slice
valve open. Run spa and check for union
water leaks before reinstalling exterior
panel.
Ground-Fault Circuit Interrupter
A qualied licensed electrician shall connect
the spa to a circuit protected by a GFCI. This
is a requirement by the National Electric
Code, article 680-42 and 680-43, and is also in
compliance with Underwriter’s Laboratories,
Inc.
Installation Options
A hole will need to be drilled in the pedestal
or base to bring the electrical conduit into
the spa cabinet.
Refer to the manufactures’s nameplate
located on the kick plate to determine your
spa’s ampere requirements.
The Model Duet comes factory set for 120
volt service.

120 Volt Installation
• 120 volt, 60 Hz, single phase, 15 amp.,
3-wire service (line 1, neutral, and
ground)
The heater can only be activated with the
pump on low speed. Only the spa light
can be operating at the same time without
disabling the heater.
Caution: Risk of electrical shock.
Read and follow all instructions.

13 VITA SPA DUET
ELECTRICAL INFORMATION
REQUIREMENTS
The spa must be connected to a dedicated
120 volt, 15 amp, grounded circuit.
The term “dedicated” means the electrical
circuit is not being used or shared for any
other electrical items (patio lights, appliances,
garage circuits, etc.). If the spa is connected
to a non-dedicated circuit, overloading may
result in “nuisance tripping” at the main panel.
CORD CONNECT
The Vita Spa Duet Model comes with a power
cord which contains the GFCI breaker. All
electrical connections from the control pack
to the outlet should be done by a qualied
electrician.
For your safety, when the electrician is
installing the 15 amp single electrical outlet
and waterproof cover, the outlet should be no
closer than 6 feet (1.83 meters) and no farther
than 10 feet from the spa [reference N.E.C.
Article 680 and all local codes]
The Ground Fault Circuit Interrupter (GFCI) is
located on the power cord. This device is for
your protection. It is very important to protect
it along with the moisture resistant cover from
damage. Test once a month, with the plug
connected to the power supply.
NEVER CONNECT THE SPA TO AN
EXTENSION CORD!
A pressure wire connector is provided on
the exterior surface of the control box, inside
the spa. This is to permit the connection of a
ground bonding wire between this point and
any metal equipment, enclosures, reinforced
concrete pad, pipe, or conduit within 5 feet
of the spa (if needed to comply with local
building code requirements). The bonding
wire must be at least a #10 AWG solid copper
wire.
Bond the spa to all exposed metal equipment
or xtures, handrails, and concrete pad per
N.E.C. Article 680 and all local codes.
1. Push the “TEST” button on the GFCI breaker.
The spa should stop operating and the GFCI
power indicator will go out.
2. Wait 30 seconds, then push the “RESET”
button. Power will be restored to the spa and
the GFCI power indicator will turn on.
If the GFCI fails to operate in this manner, your
spa may have an electrical malfunction, and
you may be risking electrical shock. Turn o
all circuits and do not use the spa until the
problem has been corrected by an authorized
service agent.
WARNING: Removal of the GFCI from the
spa’s power cord will result in an unprotected
spa and will void the spa’s warranty.
IMPORTANT: Should you ever nd the
need to move or relocate your Vita Spa, it
is essential that you understand and apply
these installation requirements. Your Vita
Spa has been carefully engineered to provide
maximum safety against electric shock.
Caution: Risk of electrical shock.
Read and follow all instructions.

14 VITA SPA DUET
START UP PROCEDURES
Follow recommendations for site location
and electrical connection. The water line on
the weir door is the level at which the water
should be maintained.
1. Fill the spa through the lter hole to
1/8” below the top of the Weir door. with
tap water. Never use ‘softened’ water in
your spa. Softened water can impact the
chemical balance of the water and lead to
degradation of metal plumbing ttings.
2. Turn power on to unit at circuit breaker or
disconnect panel.
3. Open the air controls, located on the top
lip, and cycle the jets from high to low.
Water should come from the therapy jets.
If water ow is not established, turn o jets
and see Priming Your Spa (this page).
4. Add chemicals. Ask your dealer for
additional information.on start up or
getting the water balanced.
Follow Operating Instructions for your
particular model to set heat to the desired
temperature. Initially, you may nd that
the spa requires 12 to 14 hours on 120 Volt
installations to reach temperature. Keep your
thermal cover on the unit and close the air
control to help the heating process.
Priming Your Spa
When lling your spa for the rst time or,
after draining and relling the spa, you
may need to bleed air from the system.
Should you experience an air-lock on
Pump 1, remove the lter cover,
insert a garden hose through the center
hole that holds the lter as far as possible
without using force. Hold the hose in place
and turn on the water. Cycle pump 1 from
low to high several times, this forces water
into the pump and forces the air out. If
this does not work , remove the side panel
and locate the pump. Slowly loosen the
discharge (top) pump union until water
starts to trickle out. Once water is trickling
out, hand tighten the union (do not over
tighten as this could cause the union to
crack) and replace the side panel

AM. Each cycle will run for the prescribed
number of hours.
Changing Filter Cycle Duration
The duration of a lter cycle can be set in one
hour increments of 1- 8. For example, a 2
hour cycle will complete once every 12 hours
for a total of 4 hours per day. The amount of
time needed to lter you spa will depend on
usage and ambient conditions.
You will need to program you lter cycles
based upon your personal use.
To change the duration of the lter cycles
touch the ‘TEMP’ pad and then touch the
‘JETS’ pad. Touch the ‘TEMP’ pad to adjust
the cycle duration to the desired setting. After
each press, the duration of the cycle will be
displayed in the LCD window as follows:
F1 1 Hours for each cycle, 2 hours per day
F2 2 Hours for each cycle, 4 hours per day
F3 3 Hours for each cycle, 6 hours per day
F4 4 hours for each cycle, 8 hours per day
F5 5 hours for each cycle, 10 hours per day
F6 6 Hours for each cycle, 12 hours per day
F7 7 Hours for each cycle, 14 hours per day
F8 8 Hours for each cycle, 16 hours per day
To exit the lter-set procedure, touch ‘JETS’.
The LCD window will display the current water

Setting the Time and Filtration Cycles
You can decide when your lter cycles start
and you also have choices on how long they
run.
Preset Filter Cycles. The spa control system
is designed with two lter cycles. The rst
lter cycle turns on 6 minutes after power is
supplied to the spa. The second lter cycle
turns on 12 hours later. Filter cycles are pre-set
for a two hour duration.
Note: To properly clean and maintain spa, a
total lter time of at least two hours per day
is recommended. If an ozonator is installed,
4 hours is recommended.
Changing Filter Cycle Start Time
The start/stop times of the lter cycle begin 6
minutes after the spa set time is established.
Set time is based on the time of day that
the spa is powered up. Set time may only be
changed by disconnecting power from the
spa and re-connecting it at the desired start
time. For example, if you want the lter cycle
to begin at 9:00 PM,turn o the spa breaker
and turn it back on at 8:54 PM (remember

MAINTENANCE
Water Chemistry
Water chemistry is critical in a spa system.
Chemicals are used to sanitize the water and
control the pH balance. The combination
of high water temperature and small water
volume means that the chemical balance must
be watched carefully. It is recommended that
you purchase a chemical start up kit, and
the additional chemicals needed to maintain
the proper/optimum chemical balance, from
your dealer.
Sanitizing
Sanitizing the water destroys harmful
organisms and keeps your spa healthy and
safe. Three commonly used spa sanitizer or
oxidizing agents are bromine, chlorine and
ozone. Chlorine or bromine are chemicals that
you add to the water. Ozone is a gas that is
produced by an ozonator and injected into
the water. It is important that a residual of
sanitizer remain in your water. High water
temperature, aeration and use will increase
the need for sanitizer.
In addition to maintaining a residual,
it is important to ‘shock’ your spa water
periodically and after heavy use. This addition
of substantial amounts of sanitizer super-
chlorinates the water and oxidizes non-
lterable organic residue. Allow the sanitizer
level to drop back to the residual amount
before using. Also use your Clean Up Cycle
after heavy use for additional ltration. Tests
should be done daily with your test kit to keep
a chlorine or bromine residual of 3.0 to 5.0
ppm.
pH Level
pH is the balance of acidity and alkalinity
in the water. Maintaining proper pH is
important for the eectiveness of your
sanitizer, for user comfort, and to prevent
corrosion of the spa equipment.
Caution: Never mix two chemicals together.
Caution: Never store chemicals in the
equipment compartment.
Caution: Do not use muriatic acid to balance
pH as it will damage your spa surface and
equipment.
Recommended Levels
pH: 7.2–7.6
(Ideal 7.4–7.6)
Sanitizer Residual: 3.5–5.0 ppm
Total Dissolved Solids: 100–200 ppm
Free Available Sanitizer: 3.0–5.0 ppm
Total Alkalinity: 80–100 ppm
ideal for dichlor,
trichlor, and
bromine
NOTE: Make sure you use fresh test kit
strips/chemicals. Test kits and test
chemicals should be stored in a cool,
dry location. Check the manufacturer’s
instructions to determine shelf life and
expiration date.
Ozone:
Equipping your spa with the Powerworks ™
Ozonator is a smart decision. The use of ozone
in conjunction with spa sanitizing and water
balancing chemicals helps to provide you with
a cleaner, healthier spa and reduces chemical
usage.
