IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should
be observed including the following:
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.
A wire conductor is provided on this unit to connect a minimum 6 AWG
(13.302mm2) 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
(For cord-connected/convertible units)
DANGER – Risk of injury.
a) Replace damaged cord immediately.
b) Do not bury cord.
c) Connect to a grounded, grounding type receptacle only.
(For units intended for indoor use only)
WARNING – For indoor use only. This unit is not intended for outdoor use.
(For units intended for outdoor use only)
WARNING – For outdoor use only. This unit is not intended for indoor use.
SAFETY INSTRUCTIONS

5DO NOT DIVE.
IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
(For units with GFCI)
WARNING – This product is provided with a ground-fault circuit interrupter
located on the front panel of selected swim spas and on the power cord of
120 volt convertible spas. The GFCI must be tested before each use. With the
product operating, open the service door. When the product stops operating,
this merely indicates that the door is equipped with an electrical interlock.
Next, push the test button on the GFCI and close the service door. The prod-
uct should not operate. Now open the service door, push the reset button
on the GFCI and close the service door. The product should now operate
normally. When the product fails to operate in this manner, there is a ground
current flowing indicating the possibility of an electric shock. Disconnect the
power until the fault has been identified and corrected.
DANGER – Risk of Accidental Drowning. Extreme caution must be exercised to pre-
vent unauthorized access by children. To avoid accidents, ensure that children can-
not use this spa unless they are supervised at all times.
DANGER – Risk of Injury. The suction fittings in this spa are sized to match the spe-
cific 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 spa if the suction fittings are broken or missing. Never replace a suc-
tion fitting with one rated less than the flow rate marked on the original suction
fitting.
DANGER – Risk of Electric Shock. Install at least 5 feet (1.5m) from all metal sur-
faces. As an alternative, a spa may be installed within 5 feet of metal surfaces if
each metal surface is permanently connected by a minimum 8AWG (8.4mm2) solid
copper conductor to the wire connector on the terminal box that is provided for
this purpose.
DANGER – 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.
WARNING – To reduce the risk of injury:
a) The water in a spa should never exceed 40˚C (104˚F). Water temperatures
between 38˚C (100˚F) and 40˚C are considered safe for a healthy adult.
Lower water temperatures are recommended for young children and when
spa use exceeds 10 minutes.
SAFETY INSTRUCTIONS

6DO NOT DIVE.
IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
b) Since excessive water temperatures have a high potential for causing fetal
damage during the early months of pregnancy, pregnant or possibly preg-
nant women should limit spa water temperatures to 38˚C (100˚F).
c) Before entering a spa, the user should measure the water temperature
since the tolerance of water temperature- regulating devices varies.
d) The use of alcohol, drugs, or medication before or during spa use may lead
to unconsciousness with the possibility of drowning.
e) 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.
f) Persons using medication should consult a physician before using a spa
since some medication may induce drowsiness while other medication may
affect heart rate, blood pressure, and circulation.
(For spas with a gas heater)
WARNING – Risk of Suffocation. This spa is equipped with a gas heater and
is intended for outdoor use only unless proper ventilation can be provided for
an indoor installation.

IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
DANGER – To reduce the risk of injury to persons, do not remove the suction grate.
Suction through drains and skimmers is powerful when the jets in the spa are in
use. Damaged covers can be hazardous to small children and adults with long hair.
Should any part of the body be drawn into these fittings, turn off the spa immedi-
ately. As a precaution, long hair should not be allowed to float in the spa.
WARNING – Install the spa so that water can be easily drained out of the compart-
ment containing electrical components so as not to damage equipment. When
installing the spa make sure to allow for an adequate drainage system to deal with
any overflow water. Please allow for at least 2 feet of clearance around the perim-
eter of the spa to provide enough room to access for servicing. Contact your local
dealer for their specific requirements.
WARNING – The spa should be covered with an approved locking cover when not
in use, to prevent unauthorized entry and injuries.
WARNING – People with infections, sores or the like should not use the spa. Warm
and hot water temperatures may allow the growth of infectious bacteria if not
properly disinfected.
CAUTION – Safe temperatures for swimming or aquatic exercise is around 80˚F.
CAUTION – Risk of Electrical Shock. Do not leave audio compartment open.
Audio controls are not to be operated while inside the spa.
CAUTION – Replace components only with identical components.
WARNING – Risk of Electric Shock. Do not connect any auxiliary components (for
example, additional speakers, headphones, additional audio/ video components
etc.)
to the system. These units are not provided with an outdoor antenna.
Do not service this product yourself as opening or removing covers may expose
you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
If the power supply cord(s) are damaged, water is entering the speaker, audio
compartment, or any other component in the electrical equipment compartment
area, the protective shield is showing signs of deterioration, or there are signs of
other
potentially hazardous damage to the unit, turn off the circuit breaker from the wall
and refer servicing to qualified personnel.
SAFETY INSTRUCTIONS

IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
The unit should be subjected to periodic routine maintenance once every quarter
to make sure that the it is operating properly.
DANGER – Risk of Electric Shock. A green colored terminal or a terminal marked G,
GR, Ground, Grounding or the symbol shown in Figure 14.1 of UL 1563 is located
inside the supply terminal box or compartment. To reduce the risk of electric shock,
this terminal must be connected to the grounding means provided in the electric
supply service panel with a continuous copper wire equivalent in size to the circuit
conductors supplying this equipment.
At least two lugs marked “Bonding Lugs” are provided on the external surface
or on the inside of the supply terminal box or compartment. To reduce the risk
of electric shock, connect the local common bonding grid in the area of the spa
to these terminals with an insulated or bare copper conductor not smaller than
8AWG.
All field installed metal components such as rails, ladders, drains, or other similar
hardware within 3m of the spa shall be bonded to the equipment grounding bus
with copper conductors not smaller than 8AWG.

GLOSSARY OF SPA TERMINOLOGY
1. DRAINING YOUR SPA. The drain is located behind the front panel on the
far right side, grasp the hose bib cap and turn it counter clockwise. Attach
a garden hose, if desired. Turn the black knob on the side of the valve a
quarter turn. Draining times may vary by model using the external hose
bib. A sump pump may also be used to drain the spa quickly.
2. MAIN PUMP. This produces water flow through the main jets in the spa.
The first pump may be operated on two speeds. Low speed will produce
efficient water circulation during filtration and gentle jet action. High speed
should be used for maximum jet action. The main pump is controlled by the “Jets” or “Jets I” but-
ton on the Topside Control Panel.
3. SECONDARY PUMP. This produces water flow through the other jet system in the spa (if applica-
ble). The second pump operates similar to the main pump and is controlled by the “Aux” button
on the Topside Control Panel.
4. PUMP UNION. These are used by service personnel to easily service the pump(s).
5. HEATER UNION. These are used by service personnel to easily service the heater.
6. OZONATOR. Your optional ozonator will operate in conjunction with your filtration system.

ELECTRICAL INSTALLATION REQUIREMENTS
HAVE YOUR ELECTRICIAN READ THE FOLLOWING INFORMATION BEFORE
INSTALLATION BEGINS
Electrical connections made improperly, or the use of wire gauge sizes for incurring
power which are too small, may continually blow fuses in the electrical equipment box,
may damage the internal electrical controls and components, may be unsafe and in any
case will void your warranty.
It is the responsibility of the spa owner to ensure that electrical connections are made
by a qualified electrician in accordance with the National Electrical Code and any local
and state electrical codes in force at the time of installation.
These connections must be made in accordance with the wiring diagrams found inside
the control box. This equipment has been designed to operate on 60Hz. alternating
current only, 240 volts are required. Make sure that power is not applied while per-
forming any electrical installation. A copper bonding lug has been provided on the
electrical equipment pack to allow connection to local ground points. The ground
wire must be at least 8 AWG copper wire (unless local or state codes require a heavier
gauge wire) and must be connected securely to a grounded metal structure such as
a cold water pipe. All Master Spas equipment packs are wired for 240 VAC only. The
only electrical supply for your spa must include a 50 AMP switch or circuit breaker
to open all non-grounded supply conductors to comply with section 422-20 of the
National Electrical Code. The disconnect must be readily accessible to the spa occu-
pants, but installed at least five feet from the spa. A Ground-Fault Circuit Interrupter
(GFCI) must be used to comply with section 680-42 of the National Electrical Code.
A ground fault is a current leak from any one of the supply conductors to ground.
A GFCI is designed to automatically shut off power to a piece of equipment when a
ground fault is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground (6 AWG copper) 8 AWG
copper ground.
Route the cable into the equipment area for final hook-up to terminals inside the con-
trol panel. The spa must be hooked up to a “dedicated” 240 volt, 50 amp breaker and
GFCI. The term “dedicated” means the electrical circuit for the spa is not being used
for any other electrical items (patio lights, appliances, garage circuits, etc.). If the spa
is connected to a non-dedicated circuit, overloading will result in “nuisance tripping”
which requires resetting of the breaker switch at the house electrical panel.

SITE PREPARATION / GENERAL GUIDELINES
Portable spa installation is simple when properly planned. To that end, it is important that you read
the following information carefully and consult with your Master Spas dealer.
1) Access - The actual dimensions of your new spa will determine the amount of space that is
needed in moving the spa from curbside to its final installation area. Be sure to measure side yard
dimensions, gates or doors and vertical obstructions such as roof overhangs and overhead cables.
Any other space limiting obstacles such as trees or shrubs must be evaluated.
2) If the spa is being installed indoors, dimension limitations such as stairs, ceilings and walls must
be taken into consideration. Please have your Master Spas dealer or delivery service review site
or installation plans prior to delivery.
NOTE: If you are installing your spa indoors, always be aware that if you splash water into the
speaker compartments of the spa, water will run down through the speaker drain at the floor level
toe kick, which drains below the spa in the corner where the speakers are located. Please be aware
of this as any damage is not covered by the warranty. This could cause unwarranted damage.
3) Surface/Pad Requirements - When your new spa is filled with water and bathers, it may weigh
as much as several tons. It is imperative that the base beneath the spa can support the entire
weight. The spa must be on a uniformly firm, continuous, and level surface. The recommended
foundation is a concrete pad with a minimum thickness of four (4) inches with steel reinforce-
ment bars crossed throughout the pad.
IMPORTANT
When installing your spa indoors, on a wood deck, or balcony, the same load requirements must
be met. Total load may be as much as 90 pounds per square foot. You should speak with a quali-
fied contractor or your local building department to confirm that your surface is adequate for sup-
porting a spa. Be sure to locate your spa so that equipment remains above grade and is not subject
to flooding.
The equipment side(s) of the spa must be accessible in the event that future service is needed.
Periodical maintenance checks require entry into the equipment bay. When possible, it is wise plan-
ning for the future to leave 2 feet of access to all sides of the spa in the event your spas plumbing
requires maintenance. Your spa warranty does not cover the cost of providing access for service.

INSTALLATION INSTRUCTIONS
1.) Put spa in final position that allows for access to equipment and spa components.
2.) Remove front side panel (This is the side where the main topside
control panel is located) so electrical can be hooked up to the spa
system pack. Panels are removed by unscrewing the screws in the
corner sections and side panels (using #2 square bit). Using a Phillips
screwdriver may result in stripping of the screw.
3.) Fill spa at least 1” above the filters. We recommend filling the spa
through the filter area.
4.) Turn the power on to the spa. Spa will go through its priming
mode. This lasts approximately 5 minutes.
5.) It may be necessary to bleed air from the pump(s) on your spa if, after start up, your spa pumps
do not operate.
Due to the nature of water flow and hydro-therapy pumps, please be advised that air locking of
pumps may occur. Master Spas has taken measures to reduce the possibility of this, but it still may
occur, especially after refilling a spa. This is not a service covered under warranty.
To relieve an airlock situation, loosen the union (see picture) on the discharge of the pump (see
arrow on picture of pump below). Water should leak out. Tighten the union and test the pump for
proper jet flow. If needed repeat process.
Pump Union
Airlock
6.) Adjust water chemistry according to the instructions provided in the
“Water Quality Maintenance Section” (page 20).
7.) Your spa water will heat approximately 4° - 7° per hour, for all 240V spas.
This varies depending on the size of the spa. Step into the soothing waters
of your new Master Spa!
RELAX AND ENJOY.

WATER CHEMISTRY TERMS YOU SHOULD KNOW
Before jumping into the Spa Water Maintenance, here are some terms to help you.
1. Parts per million, or ppm: This is a form of measurement used in most pool or spa chemical
readings. Best described as any one million like items of equal size and make up, next to one
unlike item , but of equal size. This would be one part per million.
2. Average size spa: What is it? The national spa and pool institute (NSPI)
states; 350 to 400 U.S. gallons is average. As a general rule, chemical dosages are the same for
any spa between 100 and 500 U.S. gallons. Spas over 500 U.S. gallons the dosage would be
double. Under 100 U.S. gallons would be on a case by case basis.
3. Total Alkalinity: This is a measurement of the ability of the water to resist changes in pH. Put
another way, it is the water’s ability to maintain proper pH. Total alkalinity is measured in parts
per million from 0 to 400 plus, with 80 to 150 ppm being the best range for spas. With low
alkalinity, the pH will flip, or change back and forth, and be hard to control. With high alkalinity
it becomes extremely difficult to change the pH.
4. pH or potential hydrogen: This is a measurement of the active acidity in the water, or it is the
measurement of the concentration of active hydrogen ions in the water. The greater the concen-
tration of active hydrogen ions, the lower the pH. pH is not measured in parts per million, but
on a scale from 0 to 14, with 7 being the neutral. In spas when ever possible, a measurement
between 7.2 and 7.8 is best. Whenever possible, it should be between 7.4 and 7.6. With low
pH, the results can be corroded metals, etched and stained plaster, stained fiberglass or acrylic,
eye / skin irritation, rapid chlorine or bromine loss, and total alkalinity destruction. With high pH,
the results can be cloudy water, eye / skin irritation, scale formation and poor chlorine or bro-
mine efficiency.
5. Shocking: This is when you add either extra chlorine (superchlorinate) by raising the chlorine level
above 8 ppm, or add a non-chlorine shock (potassium monoperoxysulfate or potassium monop-
ersulfate) to burn off the chloramines or bromamines. A non-chlorine shock acts by releasing
oxygen in the water, which serves the same function as chlorine. The advantage to using non-
chlorine shock, is you can enter the water within 15 minutes after shocking. Using chlorine,
you must wait until the total chlorine reading is below 5 ppm. One thing to remember, a non-
chlorine shock will not kill bacteria or disinfect.
6. Sequestering: This can be defined as the ability to form a chemical complex which remains in
solution, despite the presence of a precipitating agent (i.e. calcium and metals). Common names
for sequestering chemicals are; minquest, stain and scale control, metal-x, spa defender, spa
metal gone, (etc.).

18DO NOT DIVE.
Before jumping into the Spa Water Maintenance, here are some terms to help you.
7. Filtration: Filters are necessary to remove particles of dust, dirt, algae, etc. that are continuously
entering the water. If the spa is not operated long enough each day for the filter to do a proper
job, this puts a burden on the chemicals, causing extra expense. Filtration time will depend on
the spa size, pump and filter size, and of course, bather load. A spare cartridge should be
kept on hand to make it easy to frequently clean the cartridge without the need for a long
shut down. This will also allow the cartridge to dry out between usages, which will increase the
cartridge life span as much as twice. Replace the cartridge when the pleats begin to deterio-
rate. Cartridge cleaning should be done a minimum of once a month. More often with a heavy
bather load.
8. Sanitizers: This is what kills the germs and bacteria that enter the water from the environment
and the human body.
A. Chlorine
1. Only one type is approved for spa use
a. Sodium dichlor which is granular, fast dissolving and pH neutral
chlorine.
2. Chlorine is an immediate sanitizer.
B. Bromine
1. Two types of tablets.
a. Hydrotech
b. Lonza
2. Bromine is a slow dissolve chemical and may take a few days to develop a reserve or
reading in the water.
9. Total dissolved solids (TDS): Materials that have been dissolved by the water. i.e. Like what
happens when you put sugar in coffee or tea.
10. Useful life of water (in days): Water should be drained at least once every 180 days. Useful life
may vary by usage and bather load.
11. Defoamer: Foaming may be caused by body oils, cosmetics, lotions, surface cleaners, high pH
or algeacides as well as other organic materials. Low levels of calcium or sanitizer can also
cause foaming. Also, double rinse your bathing suits as they will hold residual soap after being
washed.
12. Calcium hardness: Water that is too hard (over 250 ppm) can promote scale formation in com-
ponents and on spa surface. Water that is too low (below 180 ppm) may also shorten the life
of metal components on the spa.
NOTE: Always leave the spa cover open for 15 min. after adding chemicals to prevent off
gas from damaging your spa cover, spa pillows, and other critical parts.
