GLOSSARY OF SPA TERMINOLOGY
1. DRAINING YOUR SPA. The drain is located behind the front
panel on the far right side. You can access the drain by
unscrewing the corner screws and removing the corner
panel. Grasp the drain cap, and pull the assembly out all
the way. Unscrew the cap, and push the assembly back in
half way to start the flow of water. Attach a garden hose,
if desired. Draining times may vary by model using the
external hose bib. A sump pump may also be used to
drain the spa quickly. NOTE: When pushing or pulling the
assembly in or out, water will drip from the drain during
the transition. This is normal.
2. JETS 1 PUMP. This pump produces water flow through the main jets in the
spa. This pump may be operated on two speeds. The low speed will produce
efficient water circulation and gentle jet action. High speed should be used
for maximum jet action. In spas not equipped with a 24 hour circulation
pump, this pump also moves water for the heat and filtration cycles.
3. JETS 2 PUMP. (If so equipped) This produces water flow through the
designated jets and has only one speed.
4. JETS 3 PUMP. (If so equipped) This produces water flow though the
designated jets and has one speed.
5. CIRCULATION PUMP. (If so equipped) This pump runs 24 hours a day and
moves water for heating and filtration. Spas equipped with this pump do not
have filtration cycles as they are not necessary in this configuration.
6. JET DIVERTER VALVE. 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.
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.
7. PUMP UNION. These are used by service personnel to easily service the
jet pump(s).
8. HEATER UNION. These are used by service personnel to easily service the
spa heater assembly.
9. OZONATOR. Your ozone generator will operate
in conjunction with your filtration system. It will
deactivate when any other control function is manually
activated and will reactivate after one hour.
Ozonator (optional)

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 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 (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 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 current fault 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
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.
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, 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
department 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 service 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.
14
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
15
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 the electrical
service can be hooked up to the spa system pack. The
panels can be taken off by first removing the three
black thumb screws located on each corner. On the
center panel there are four #2 Phillips screws that are
covered with a colored snap cap. Remove the caps to
access the screws for removal.
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 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 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 (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.
Pump Union
Airlock
6.) Adjust water chemistry according to the instructions provided in the
“Spa Water 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.
16
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 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 and 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.).
17
WATER CHEMISTRY TERMS YOU SHOULD KNOW
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 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 dissolving,
and pH neutral
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 components 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.

WATER QUALITY MAINTENANCE SCHEDULE
BEFORE EACH USE -
Check spa water with a test strip for proper sanitation
levels and adjust accordingly to the proper levels.
ONCE A WEEK -
Add 3 Tablespoons of a non-chlorine shock or
1 teaspoon of Dichlor to spa per 250 gallons.
3 TIMES A WEEK -
Test water using chemical test strips. Adjust sanitizer,
pH and Alkalinity accordingly.
ONCE A MONTH* -
Soak your filter element overnight in a bucket with
spa Filter Cleaner and then rinse with clean water
before re-inserting.
EVERY 180 DAYS -
Drain and refill your spa. Repeat start up procedure.
AFTER EACH USE -
Add 1 tablespoon of non-chlorine shock or 1/3
teaspoon of Dichlor to spa per 250 gallons.
AS NEEDED -
If water looks hazy, shock treat with 1 teaspoon of
Dichlor per 500 gallons.
* These are general recommendations for water quality maintenance that
may vary by usage and or bather load. Depending on bather load and
frequency of use, drain and refill times may vary as well as the frequency
of cleaning your filters.
* Foam Gone may be used when excessive foaming occurs. Be sure to use
only a drop or two at a time. Over use of Foam Gone will result in cloudy,
milky water.
NOTE:
As an alternative to non chlorine shock, Dichlor may be substituted.
1 tsp. Dichlor = 3 tablespoons of non chlorine shock
USE ONLY SPA CHEMICALS
(some pool chemicals are not suitable for spa use).
* when cleaning filters, be sure to never have the pump(s) running without
the filter in place. Failure to do so may result in debris in the pumps causing
unwarranted damage.

SPA WATER MAINTENANCE - START-UP
1. Read the spa owners manual first.
2. Clean the surface with a spa general purpose cleaner or wipe down with a
clean wet towel.
3. Begin filling the spa with fresh water. If possible, do not use softened water.
4. When the spa has 2 to 4 inches of water on the bottom, add the recommended
amount of a sequestering chemical for that size spa. See the chemical bottle
for correct amounts.
5. When the spa is full, run the pump on high speed for 30 minutes without air
controls open. This will give the sequestering chemical time to mix well with
the water. Allow sequestering chemical 12-24 hours to properly filter in the
water before proceeding with any further steps.
6. Using test strips or a test kit, test for total alkalinity, and adjust if necessary
to between 80 to 150 ppm using the pH / alkalinity increaser or decreaser 1oz.
at a time. Wait 15 minutes, retest, and adjust if necessary. The pump should
be running on high speed during this time.
7. Using test strips or a test kit, test for pH, and adjust if necessary to within the
7.2 and 7.8 range using the pH / alkalinity increaser or decreaser 1/2oz. at a
time. Wait 15 minutes, retest, and adjust if necessary. The pump should be
running on high speed during this time, without air controls open.
8. Add the sanitizer of choice, following label directions. If chlorine is used,
broadcast the recommended amount across the surface of the water, with the
pump running on high speed. Wait 15 minutes, retest, and adjust if necessary
to a total chlorine reading of 1 to 3 ppm. If bromine is used, add bromine
tablets to the bromine feeder following label directions. With the pump
running on high speed, add 2oz. of sodium bromide, and shock the spa with
2oz. of non chlorine shock. It may take several days adjusting the bromine
feeder to obtain a total bromine reading of 3 to 5 ppm. A bromine reading
may not be obtained on the first day.
9. If any foam develops, add a defoamer at the base of the problem area. Use
only enough defoamer to get rid of the foam. This is usually one or two
drops. Do not pour large amounts of defoamer into water.
10. Wait two days, and begin a three day a week maintenance program.
20
SPA WATER MAINTENANCE - START-UP
DAY ONE
1. Test and adjust total alkalinity if necessary to between 80 to 150 ppm using
the pH / alkalinity increaser or decreaser 1oz. at a time. Wait 15 minutes,
retest and adjust if necessary. The pump should be running on high speed
during this time with the air controls closed.
2. Test and adjust pH, if necessary, to within the range of 7.2 to 7.8 using the
pH / alkalinity increaser or decreaser, 1/2oz. at a time. Wait 15 minutes,
retest and adjust if necessary. The pump should be running on high speed
during this time with the air controls closed.
3. Test and adjust sanitizer level. Add chlorine following label directions to
maintain a free chlorine level of 1 to 3 ppm. If using bromine, adjust feeder
to maintain a total bromine level of 3 to 5 ppm. Add bromine tablets to the
dispenser if necessary, following label directions.
4. Add a water clarifier following label directions. If the spa is equipped with
an ozone unit, we recommend adding an enzyme product in place of the
clarifier, following the label directions.
5. Use a small amount of defoamer only if necessary.
DAY TWO SKIP
DAY THREE
1. Test and adjust total alkalinity, if necessary, to between 80 and 150 ppm using
the pH / alkalinity increaser or decreaser, 1oz at a time. Wait 15 minutes,
retest and adjust if necessary. The pump should be running on high speed
during this time with the air controls closed.
2. Test and adjust the pH, if necessary, to within the range of 7.2 to 7.8 using
the pH / alkalinity increaser or decreaser, 1/2oz at a time. Wait 15 minutes,
retest and adjust if necessary. The pump should be running on high speed
during this time with the air controls closed.
3. Test and adjust sanitizer level. Add chlorine following label directions to
maintain a free chlorine level of 1 to 3 ppm. If using bromine, adjust feeder
to maintain a total bromine level of 3 to 5 ppm. Add bromine tablets to the

3. Test and adjust sanitizer level. Add chlorine following label directions to
maintain a free chlorine level of 1 to 3 ppm. If using bromine, adjust feeder
to maintain a total bromine level of 3 to 5 ppm. Add bromine tablets to the
dispenser if necessary, following label directions.
4. Shock with 2oz. of non chlorine shock, or superchlorinate following label
directions. A spa should be shocked at least once a week even if it is not
used. If using chlorine as the sanitizer, the spa should be shocked whenever a
free chlorine reading of 1 to 3 ppm cannot be obtained without raising the
total chlorine level above 5 ppm. Always shock a spa after any heavy bather
load.
5. Check filter cartridge and clean if necessary. Clean with cartridge filter
cleaner, following label directions. It is best to have a spare cartridge on
hand, to prevent long spa down times while the cartridge is being cleaned.
Never operate your spa without the filters in place.
6. Use a defoamer only if necessary.
DAY SIX AND SEVEN SKIP
With a spa, you are working with a small volume of hot water, which causes
chemicals to have a shorter life span, and bacteria, along with other things, to
grow faster. A spa is less forgiving than a pool, and requires that whatever is
put into it have a pH as close to neutral as possible. That is why only chemicals
made for spas should be used.

WHY CHEMICALS ARE IMPORTANT IN A SPA
1. Evaporation: As water evaporates, only pure water evaporates, leaving the
salts, minerals, metals, and any unused chemicals behind. Adding water adds
more salts, minerals, and metals. In time, the water can become saturated
with these dissolved solids and can cause stains or scale to form on the walls
of the spa or a scale build up inside the equipment. Colored or cloudy water,
and possible corrosion of plumbing and fittings may also occur.
2. Heat: Heat causes evaporation to happen faster. Heat also causes certain
minerals and metals to precipitate out of solution.
3. Air: Dust and airborne dirt particles are introduced into the spa.
4. Environment: The environment surrounding the spa is also a consideration.
Watch for pollen, grass, sand, dirt, lawn fertilizer, dust storms, insects,
dogs, cats, etc.
5. Consider the human next: In a heated spa, the average adult sweats 3 pints
per hour. This person also brings in the spa surface dirt, soap, body oils,
deodorant, hair spray, hand and body lotion, perfume and cologne, make up,
lipstick, and suntan lotion. To this you can add spit, urine, bacteria and virus
germs from open sores or certain body parts. To this let’s add spilled drinks,
cigarette ash, and various play things. Now multiply this times 4 or 6 people
in an average 375 gallon spa and then try to use the water for a few months!
REMEMBER:
The maintenance routines set forth in this manual may need to be adjusted
depending on how much the spa is being used.
24
MAINTENANCE RECOMMENDATIONS
Your spa requires periodic draining and cleaning to ensure a safe, healthy
environment. It is recommended that you clean your spa at least every 180 days.
Heavy bather load will require cleaning it more often.
TO DRAIN YOUR SPA
• See page 11.
TO CLEAN YOUR SPA SURFACE
• With a soft cloth, wipe down the spa surface with a non-abrasive spa surface
cleaner that may be purchased through your local spa dealer. Do not use paper
towels. Be sure to rinse residue from spa surface.
• If your spa has developed an oily or chalky residue at the waterline it may
require special treatment. Consult your dealer.
TO REFILL YOUR SPA
• Be sure to close the drain valve.
• Fill the spa with water. Be sure water level is above skimmer opening to the
minimum safe water level label.
• Refer to your spas corresponding start-up section with any questions.
TO CLEAN YOUR FILTER ELEMENT (also reference page 36)
The filter in your spa is one of the most important components of your spa.
It not only is essential for clean water, but also for extending the life of the spa
equipment. Your filter element must be cleaned regularly (once a month on
average) with normal spa use. With heavy use, they will need to be cleaned
more often.
• Turn spa off. Never have the spa running when removing your filter as debris
can be pulled through into the equipment causing unwarranted damage.
• Remove filter element.
• With a garden hose, spray the element under pressure. Periodically, the
element needs to be soaked in a filter cleaner compound. Check with your
dealer for details on cleaning and/or filter replacement recommendations.
• Replace filter element.
• Be sure water level is adequate.
• Turn spa on.
CARE OF YOUR SPA PILLOWS
• Your spa pillows need to be rinsed periodically to remove any chemical residue.
This should help to eliminate pillows becoming stiff and discolored.
• If spa is not to be used for a period of time, pillows should be removed.
Pillow life will be extended.
25
WINTERIZING YOUR SPA
Many people find they enjoy using their spa more in the winter than any other
time. Your spa is designed to be used year round in any type of climate.
*However, if you decide you don’t want to use your spa in the winter, you must
drain it and follow the winterizing steps listed below:
1.) Drain your spa completely using the drain valve (see "To Drain Your Spa")
or use an inexpensive submersible pump that you can buy from your dealer
or your local hardware store.
2.) Use a shop vac to get all standing water out of your unit.
3.) Remove access panels from equipment area.
4.) Loosen all pump unions
5.) Remove winterizing plug from the face of the pump(s).
6.) Using your shop vac in a blowing mode, insert the hose into the nozzle
of each jet and blow the trapped water from the lines into the interior
of the spa.
7.) After this is completed, use the shop vac to remove any standing water
in the spa and in the equipment area.
8.) Clean the spa with a soft cloth and a non-abrasive spa surface cleaner.
9.) Replace access panels.
10.) Cover spa to prevent water from entering the spa.
* Disclaimer: Master Spas does not recommend winterizing your spa.
If you choose to do so, any damage that may result is not covered
under the spa warranty.

SPA TROUBLE-SHOOTING GUIDE
NOTHING ON THE SPA OPERATES1.) Check the control panel display for any messages. If there is a message,
refer to the diagnostic section. There you will find the meaning of the
message and what action is to be taken.
2.) If there is no message on your control panel, check and reset the GFCI and
house breaker.
*The GFCI should be located in a weather proof box
close to the spa, but no closer than 5 ft.
If the spa does not respond, contact your local service company.
PUMP(S) DO NOT OPERATE 1.) Press the “Jets” button on your control panel.
If you hear the pumps trying to operate:
A. Pump may need to be primed. See page 16.
If you do not hear anything from the pump, contact your local service
company.
POOR JET PERFORMANCE
1.) Make sure pump is operating
2.) Check that the water level is adequate (up to minimum safe water level side)
3.) Make sure the jets are open.
4.) Check for dirty filter. Clean if necessary.
38
SPA TROUBLE-SHOOTING GUIDE
SPA NOT HEATING
* If the spas heater has failed, the majority of the time it will trip the
GFCI breaker. If the spa is not heating and has not tripped the breaker,
please follow these steps:
1.) Check the control panel for diagnostic messages. Refer to spa diagnostic
message area in previous sections.
Follow steps to alleviate message.
2.) Check water set temperature at control panel.
3.) Check for dirty filter. Clean if necessary.
4.) Check “heat mode” the spa is set in. Spa should be in standard mode.
5.) Check the control panel for heater light indicator. If the light is on, the spa
should be heating. Wait a reasonable amount of time (approximately 1 hour)
to see if the water temperature is changing.
6.) Check to make sure that the pump is primed.
7.) Reset power to the spa at GFCI breaker.
8.) If spa is still not heating, contact your dealer for service.
GFCI IS TRIPPING
The Ground Fault Circuit Interrupter (GFCI) is required,
by NEC code (National Electrician Code), for your
protection. The tripping of the GFCI may be caused
by a component on the spa or by an electrical problem.
Such electrical problems include, but are not limited to,
a faulty GFCI breaker, power fluctuations, or a miswire.
It may be necessary to contact an electrician if your
local dealer recommends doing so.

REGULAR MAINTENANCE PROCEDURES
Note: These are areas that will require the spa owner to perform routine
maintenance. These are not areas covered under the warranty of the spa.
CLEANING JETS
The majority of jets in your spa can individually be
turned on/off. If any of these jets become hard to
turn, it will be necessary to remove the jet to clean
it as grit/sand and mineral deposit may be present.
Jets are removed by turning the collar and then
pulling out the jet. Some jets may not be removable
depending on model.
TO CLEAN JETS
Place the jet(s) in a bucket, fully immerse in white vinegar. Let the jet(s) soak
overnight and then rinse with water. Reinstall the jet(s). It may also be necessary
to clean the grit/deposit from the white jet body using an old toothbrush.
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.
40
REGULAR MAINTENANCE PROCEDURES
CARE OF YOUR SPA COVER
Always cover your spa when not in use. This will greatly reduce energy
consumption and will cause spa water to heat more rapidly. Water loss
and chemical usage will also be reduced.
• Be sure to lock down all straps on cover after each use to prevent
wind damage.
• Do not allow spa to sit uncovered in direct sunlight. This may cause damage
to exposed surfaces of spa and possible discoloration of spa fittings.
• Periodically hose off both sides of spa cover for maximum life of cover. Once a
month use a vinyl cleaner and conditioner on the vinyl portion of your cover.
Rinse residue off.
• Keep cover open for 15 min. after adding chemicals to prevent off gas damage.
NOTE: IF YOUR SPA IS GOING TO BE LEFT EMPTY FOR PROLONGED PERIODS,
DO NOT REPLACE COVER DIRECTLY ON SURFACE OF SPA. PLACE 2"-3" BLOCKS
BETWEEN COVER AND SPA. THIS ALLOWS FOR ADEQUATE
VENTILATION OF COVER AND SPA.
NOTE: The cover warranty is provided through the cover manufacturer and not through
Master Spas. You will need to mail the cover warranty back to the cover manufacturer.
CARE OF YOUR SPA CABINET
Your quality Polymer Skirt simply needs to be hosed off periodically.
No other maintenance is required.
FILTER CLEANING
NOTE: Never operate the spa without filter in place.
If done, damage will result to pumps and other components.
We recommend having an extra filter to install when cleaning
the filter.
1.) Turn power off to the spa.
2.) Remove any large or floating debris from the filter area.
3.) Remove the filter. Filter should be periodically rinsed and soaked in a
cartridge cleaner. Follow cartridge cleaner instructions.
