SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions
should be observed including the following:
Important Safety Instructions
1. WARNING. To reduce the risk of injury, do not permit children to use this
product unless they are closely supervised at all times.
2. DANGER - RISK OF CHILD DROWNING. Extreme caution must be
exercised to prevent unauthorized access by children.To avoid accidents, insure
that children cannot use a spa or hot tub unless they are closely supervised at
all times.
3. A pressure wire connector is provided on the surface of the control box inside
the spa to permit connection of a minimum No. 8 AWG solid copper bonding
wire between this point and any metal equipment, metal enclosures of electrical
equipment, metal water pipe or conduit within 5 feet (1.5M) of the unit.
4. DANGER - RISK OF ELECTRIC SHOCK. Install spa at least five (5) feet
(1.5M) from all metal surfaces. A spa may be installed within five (5) feet
(1.5M) of metal surfaces if, in accordance with the National Electrical Code,
each metal surface is permanently connected by a No. 6 AWG (8.4mm) solid
copper conductor attached to the wire connector on the terminal box.A
grounding plug is provided for this purpose.
5. DANGER - 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 fitting or the pump be sure that the flow rates are compatible.
*NOTE: 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.
6. DANGER - To reduce the risk of injury to persons, do not remove 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
immediately. As a precaution, long hair should not be allowed to float in the spa.
7. Install spa so that water can be easily drained out of the compartment containing
electrical components so as not to damage equipment. Also, when installing spa,
allow enough room to access for servicing. Contact your local dealer for their
requirements.

5. JET DIVERTERVALVE - Located on the topside of the spa, this valve
physically diverts the flow of water from one jet zone of the spa to another
jet zone (featured on the LSI, LSX and select Down East models)
Be sure that no sand or particles are brought into the spa as they will cause the
diverter to seize up. It is best to turn the diverter valve only when the pump is
turned off.
Your new Master Spa features a variety of jet
styles. All jets, regardless of style return the
water to the spa. Air is mixed with the water
by using the air controls creating a gentle to
most vigorous massage. Water flow is adjusted
by simply turning the outer face of the jet.
Your Master Spa will have a combination of
pulsating, rotating, dual pulsating and direc-
tional adjustable jets. The LS, LSI Series and

ELECTRICAL INSTALLATION REQUIREMENTS
HAVE YOUR ELECTRICIAN READTHE 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 Electric 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 60 HZ alternating current only, 240 volts are required.
Make sure that power is not applied while performing 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 6 AWG copper 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 240VAC 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 occupants, 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 fault current is detected.
Power hook-up to the spa must be 240 volt 3 wire plus ground
(6 AWG copper). Route the cable into the equipment area for final hook-up to
terminals inside the control 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 impor-
tant 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.
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 actual 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
reinforcement bars crossed throughout the pad.
IMPORTANT
When installing your spa indoors or 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 qualified contractor or your local building depart-
ment to confirm that your surface is adequate for supporting 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 serv-
ice is needed. Periodical maintenance checks require entry into the equipment
bay.When possible, it is wise planning for the future to leave 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.

SITE PREPARATION / GENERAL GUIDELINES
GENERAL CONSIDERATIONS FOR OUTDOOR INSTALLATION
Again, proper planning will increase your total enjoyment factor with your new
spa. Listed below are some additional items to consider when planning your
installation.
• How spa will complement landscaping and vice versa
• View from inside spa and view of spa from inside of home
• Exposure to sunlight and shading from trees
•Privacy
• Getting to spa from house and return
• Proximity to dressing rooms and bathrooms
• Storage for spa chemicals
• Local building codes (if applicable)
• Power cable
GENERAL CONSIDERATIONS FOR INDOOR INSTALLATION
Installing your spa indoors creates an entirely different set of considerations.
Here again, with proper planning, no matter what room your spa goes in, it will
be your favorite room.
• Work with your Master Spas dealer and contractor to insure all local
building, electrical and plumbing codes are met
• Plan for a floor drain to drain off excess water or for draining and cleaning
your spa
• A ventilation fan may be necessary due to high humidity created by your spa
• Finished material in your spa room should also be capable of withstanding
increased humidity

INSTALLATION INSTRUCTIONS
1.) Put spa in final position that allows for access to equipment of 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
then lifting up the panels out of the retaining tracks.
4.) Be sure all pump and heater unions are secure. Each pump has 2 unions and
the heater has 2 unions. A newly delivered spa may have loose unions caused
in transporting the spa. Check that all slice valves are open, in the up
position. Again, the slice valves may become closed during transportation
of the spa.
Be sure outside drain fitting is fully closed.
5.) Fill spa to the "minimum safe water level" sticker.We recommend filling the
spa through the filter area.
6.) Turn the power on to the spa. Spa will go through its priming mode.
This lasts approximately 5 minutes.
7.) Be sure the jets in your spa are opened.
On all Master Spas / Down East: The jets open by turning the jet
collar clockwise.
On all Freedom Spas: The jets open by turning the jet collar counter
clockwise.The smaller jets in the Freedom line cannot be opened
or closed.
Note:The Master Blasters are only turned on/off through the use of the
“Jets 3” button or the divertor valve.

INSTALLATION INSTRUCTIONS
8.) It may be necessary to bleed air from the motor(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 possiblilty 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 (the end of the pump that water is being pushed through). Water
should leak out. Tighten the union and test the pump for proper jet flow.
If needed repeat process.
9.) Adjust water chemistry according to the instructions provided in the
"SpaWater Maintenance Section" (page 20) for Master Spas and Down
East Spas. Freedom Spa models should follow the " Spa Water
Maintenance-Initial Start-Up Section" (page 24).
10.) Your spa water will heat approximately 5° - 8° 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 Maintence, 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 concentration 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, poor chlorine or bromine
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 monopersulfate) 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.).

WATER CHEMISTRY TERMS YOU SHOULD KNOW
Before jumping into the Spa Water Maintence, 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 with out 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 deteriorate. 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 good for spa use
a. Sodium dichlor which is a granule, fast disolving,
and pH neutral
2. Chlorine is an immediate sanitizer.
B. Bromine (Note: Bromine use is not recommended with Eco Pur filters.)
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 components and on spa surface. Water that is too low
(below 180 ppm) may also shorten the life of metal components on the spa.
