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 product 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
prevent unauthorized access by children. To avoid accidents, ensure that children
cannot 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
specific 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
suction 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
surfaces. 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 (8.4mm
2
) 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 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.

GLOSSARY OF SPA TERMINOLOGY
Your new Master Spa features a variety of jets. All jets, regardless of style return the water to the
spa. Air is mixed with the water by using the air controls (if equipped) creating a vigorous massage.
Water flow is adjusted by simply turning the outer face of most jets. Your Master Spa may have a
combination of pulsating, rotating, dual pulsating and directional adjustable jets.
1. THERAPY JETS
Located throughout the seats of the spa to offer a variety of therapy combinations.
2. NECK JETS (if equipped)
Located above the normal water level to provide massaging action to the back of the neck.
3. SHOULDER JETS (if equipped)
Located above the normal water level to provide massaging action to the shoulders.
4. MASTER BLASTER FOOT THERAPY JET (if equipped)
Large jet with several fixed nozzles located in the bottom of the spa near the floor to provide
excellent massage to the feet.
5. JET DIVERTER VALVE (if equipped)
Located on the top flange of the spa, this large valve physically diverts the flow of water from
one group of jets to another. 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.
6. WATER FEATURE VALVE (if equipped)
Located on the top flange of the spa, this smaller valve adjusts water flow to the waterfalls and/
or water features in your spa.
NOTE: When the spa is not in use, this valve should be turned mostly shut (not completely shut)
to prevent the water features from allowing water to hit the cover while it is closed. If
left mostly open, water may hit the cover and possibly run out of the spa causing water
loss.
7. 3-WAY DIVERTER JET (if equipped)
This large jet can be turned 180˚ to 3 different points and diverts
the flow of water from one group of jets to another. With the
pump turned off, twist the face of this jet 1/4 turn at a time
clockwise or counterclockwise to adjust.
15DO NOT DIVE.
GLOSSARY OF SPA TERMINOLOGY
8. AIR CONTROL VALVE
These smaller valves are located around the top of your spa. You may increase or decrease
the force of your jets by opening or closing the air control valves. Each air control valve will
typically function 1 to 2 groups or seats of jets in the spa. When not in use the air controls
should be kept in the closed position as the air being introduced in to the water can tend to
cool the water and increase the dissipation rate of sanitizer levels.
9. TOPSIDE CONTROL PANEL
You may safely control spa functions from inside or outside your spa using the Topside
Control Panel. This Panel is used to control the water temperature, pumps, the spa light,
automatic filtration cycles and other advanced functions. The digital display will give you a
constant temperature readout and will notify you in case of certain malfunctions. Several user
programmable functions are also available.
10. PERSONAL REMOTE CONTROL (if equipped)
Select spa models may have an additional remote which allows the user to control the jet
therapy while remaining in the seat (if applicable). By pressing the control one time, you will
activate the pump. Press again for high speed and again to turn it off.
11. EQUIPMENT ACCESS PANEL
This is the skirt panel located below the Topside Control Panel. This area houses the majority of components responsible for the spas operation. These components include the pumps,
heater, spa control system, ozonator (if equipped), and LED light system (if equipped). Pump
and equipment placement may vary by model.
12. ACCESS PANELS
These are the skirt panels located around all four sides of the spa. All of the skirt panels are
removable should service be required. Master Spas recommends at least 3 feet of access be
provided around the spa.
13. FILTER LID
This lid fits over the filter area and weir gate to cover the filters. Remove filter lid to access
filters for maintenance.
14. WEIR GATE
The weir gate is the horizontal door located in front of the filters that helps keep debris
trapped in the filter area
15. SPA CONTROL SYSTEM
This houses the wiring and electrical components necessary to operate the spa.
16DO NOT DIVE.
GLOSSARY OF SPA TERMINOLOGY
16. SPA HEATER
This is an electric heater housed in a stainless steel tube. It is thermostatically controlled and
equipped with high-limit temperature safety shut-off sensors.
17. SLICE VALVES
These valves are used by service personnel to shut off water
to the heating system (heater and pump plumbed to the
heater) so that the spa water does not need to be drained
if the spa requires service to the heating system (varies by
model).
NOTE: Slice valves must be completely open during normal
operations.
18. MAIN THERAPY PUMP
This produces water flow through the main jets in the spa. The first pump may be operated
on two speeds (varies by model). Low speed (if applicable) will produce efficient water circulation during filtration, heating of the spa water, and gentle jet action. High speed provides
maximum jet action. The main pump is controlled by the “Jets” or “Jets I” button on the
Topside Control Panel.
19. SECONDARY THERAPY PUMP (if equipped)
This produces water flow through 1 to 2 groups or seats of jets in the spa. The second pump
operates similar to the main pump and is controlled by the “Jets II” or “Aux” button on the
Topside Control Panel.
20. THIRD THERAPY PUMP (if equipped)
This produces water flow through 1 to 2 groups or seats of jets in the spa. This is controlled
by the Jets III button on the Topside Control Panel.
21. CIRCULATION PUMP (if equipped)
This produces water flow through the heater in the spa and provides the water flow
necessary to actuate the ozone injector. This energy efficient pump typically runs 24 hours
for efficient filtration and heating.
22. PUMP UNION
This connects the plumping and pump together. These are used to help relieve possible pump
air locks or for service personnel to easily service the pumps.
23. HEATER UNION
These are used by service personnel to easily service the heater.

WATER CHEMISTRY TERMS YOU SHOULD KNOW
Before jumping into 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.
3. Total Alkalinity: Measures substances in your water such as hydroxides, carbonates and
bicarbonates. When at the proper levels, these elements keep your water from clouding and
growing bacteria, as well as prevent the inner workings of your hot tub from deteriorating
or forming scale. TA also helps to stabilize pH. The higher the TA level (as long as it is within
the recommended range), the less likely the pH is to change. You are looking for a range
between 80 - 120 ppm. With low alkalinity, the pH will fluctuate and be harder to control.
With high alkalinity, it becomes extremely difficult to change the pH.
4. pH or potential hydrogen: This indicates the acidity or basicity of the water. The goal is to
have a neutral, stable pH to prevent spa damage and unhealthy conditions. Low pH levels can
corrode metals, etch or stain fiberglass or acrylic, cause unsanitary conditions that irritate the
eyes or skin and destruct the total alkalinity of the water. High pH can cause cloudy water,
eye or skin irritation, scale formation and poor chlorine or bromine efficiency. Note that the
chemicals you are using to sanitize and clean your hot tub can also lower or raise the pH level
in the water. You want this range to fall between 7.2 - 7.6 on the scale. Unfortunately, there
are lots of variables to preventing high pH in your hot tub. You can use the chart to the right
to help you balance it.
5. Shocking: By shocking the water in your hot tub, you remove organic compounds from the
water, kill bacteria, remove bromamines or chloramines and reactivate the bromides in the
spa for cleaner water. You should shock your water once a week, after heavy bather use or
any time free chlorine levels test lower than total chlorine levels. To do this, either add oxidizer/non-chlorine shock to burn off the chloramines or add extra chlorine to raise the chlorine level above 8 ppm. Oxidizer/non-chlorine shock acts by releasing oxygen in the water,
which serves a similar function as chlorine. An advantage to using this type of shock is that
the water is safe to enter after 15 minutes of the application and excessive sanitizer (chlorine)
levels do not occur. However, an oxidizer/non-chlorine shock doesn’t disinfect the water for
bacteria. If you use chlorine to shock, you must wait until the total chlorine reading is below
5 ppm.
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). If the minerals and metals in water are not sequestered, they can cause a reaction, turning the water
brown, red, orange or green depending on the minerals and metals present in your water. It
is important to add a sequestering agent when adding water to your hot tub and even on a
regular basis (if bottle instructions recommend doing so). Common names for sequestering
chemicals are; minquest, stain and scale control, metal-x, spa defender, spa metal gone, (etc.).
7. Filtration: Filters are necessary to remove particles of dust, dirt, algae, etc. that are continu-
ously 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 water capacity, pump and filter size and, of course, bather load. Spare filter
cartridges 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. See “Filter Cleaning” in the Regular Maintenance section.

8. Sanitizers: Germs and bacteria enter the water from the environment and the human body; a
sanitizer keeps the water balanced and safe to use. Either chlorine or bromine can be used as
a sanitizer to create a healthy water environment.
A. Chlorine:
1. Only one type is approved for spa use. Sodium dichlor which is granular, fast dissolving and pH neutral chlorine.
2. Chlorine is an immediate sanitizer and will be added as needed to maintain free chlorine levels between 2.0 to 4.0 ppm.
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. Bromine levels should be maintained between 2.0 to 4.0
ppm.
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: A chemical used to temporarily reduce foaming. Causes of foaming include body
oils, cosmetics, lotions, surface cleaners, high pH or algae, as well as other organic materials.
Low levels of calcium or sanitizer can also cause increased foaming. Note that you may need
to physically remove the foam and/or drain all or part your water to remove or dilute the
causes of the foam.
12. Calcium hardness: This measurement tells you how much magnesium and calcium are in your
water. However, calcium hardness can react with all of the chemicals, bacteria, dirt and other
substances that your water dissolves and get thrown out of balance. Just like the other elements, calcium levels must remain balanced and need to be monitored or you run the risk
of metal deterioration, water foaming or clouding and scale formation at the surface of your
water. The calcium hardness of your water should fall between 150 - 250 ppm.
NOTE: Always leave spa cover open for 15 minutes after adding chemicals to prevent the off
gas from damaging your spa cover, spa pillows, stainless steel hardware and other critical
parts.
WATER CHEMISTRY TERMS YOU SHOULD KNOW
19DO NOT DIVE.
WHY ARE CHEMICALS 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 much quicker evaporation and also will cause minerals and metals to precipitate
out of solution.
3. Air:
Dust and other airborne contaminants are introduced into the spa.
4. Environment:
The environment surrounding the spa can also impact the water quality. Items such as pollen, grass, sand, dirt, lawn fertilizer, airborne dust, insects, leaves, and pets can all affect the
water quality of the spa.
5. Bathers:
As the spa is used, bathers introduce contaminants to the water. Increased bather load,
length of use and frequency will increase the amounts of contaminants added in to the
water.
Remember:
The maintenance routines set forth in this manual may need to be adjusted depending on bather
load and how much the spa is being used.
20DO NOT DIVE.
Step 1: Your spa should be filled using a Pre-filter, which can be obtained from your local
dealer. This Pre-filter will help remove many of the minerals existing in the water,
which will make adjusting the water balance easier after a new fill. Never use more
then 50% softened water when filling the spa.
Step 2: During the initial filling of the spa, add a sequestering agent to combat suspended
minerals in the water. The agents are sold under many different names such as Mineral
Clear or Metal Protect. Allow water to circulate and filter for at least 30 minutes
(or per bottle recommendations) before adding any other chemicals.
Step 3: Test water for pH, total Alkalinity, and Calcium hardness. The pH should be 7.4 - 7.6
and the total Alkalinity 100 - 120 ppm. Calcium hardness levels should be maintained
between 150 and 250 ppm (part per million).
Step 4: Adjust pH and total Alkalinity (TA) utilizing the directions on the chemical bottles.
Wait 15 minutes, test and adjust if necessary.
Step 5: It may be necessary to retest and add additional chemicals to get to the proper levels
in Step 3.
Step 6: Add concentrated chlorinating granules* (sodium Dichlor-s-triazinetreone) to reach a
Free Chlorine level of 5 to 8 ppm on initial start up to begin sanitizing the spa water.
Bathers should not enter the spa until the chlorine levels drop below 5.0 ppm. Always
refer to the chemical manufacturers dosage recommendations listed on the container.
It is important not to add the chlorinating granules until the pH, alkalinity and calcium
hardness have been adjusted to their proper levels.
*SPECIAL NOTE:
We recommend a minimum level of 2.0 ppm residual free chlorine be maintained in spa water. Always refer to
the chemical manufacturer’s dosage recommendations listed on the container.
When adding chlorine or non-chlorine shock/oxidizer always spread it across the water while the pumps are running.
The quantities of sanitizer and oxidizer shown in this manual are for 500 gallon spas and may have to be adjusted depending on the actual amount of water that your spa holds. See the specifications section of this manual
for the correct gallons of your spa.
The concentration of active ingredients in spa chemicals varies by manufacturer. The amounts of sanitizer suggested in this manual are based on spa chemicals that have the active ingredient percentages listed below:
Chlorine Non-Chlorine Shock/ Oxidizer

WATER MAINTENANCE – START-UP
21DO NOT DIVE.
BEFORE EACH USE
Check spa water with a test strip for proper sanitation levels and adjust accordingly to the proper
levels. Free chlorine level should be 2.0 - 4.0 ppm. Appropriate levels should be present before use
of the spa. Bathers should not enter the spa if total chlorine levels are above 5.0 ppm or if free
chlorine levels are below 2.0 ppm.
ONCE A WEEK
Add non-chlorine shock/oxidizer* or chlorine* to spa to help maintain the water quality.
3 TIMES A WEEK
Test water using chemical test strips. Adjust sanitizer, pH and Alkalinity accordingly. The total alkalinity should be between 100 - 120 ppm and the PH should be between 7.4 - 7.6. If free chlorine
level measures less than total chlorine level, additional non-chlorine shock/oxidizer* treatment is
necessary.
ONCE A MONTH
Soak your regular filter elements overnight in a container with spa Filter Cleaner and then rinse
with clean water. For best results, allow the filter to dry before re-inserting. When cleaning filters,
be sure to never have the pumps (including the circulation pump) running without the filters in
place. Failure to do so may result in debris being drawn into the pumps causing unwarranted
damage.
See the “clean your filter elements” in the maintenance section of this manual for more
information.
EVERY 180 DAYS
Drain and refill your spa with fresh water, install a new filter element, clean the regular filter, and
repeat start up procedure. The regular filter should be replaced at least once every year.
AFTER EACH USE
Add non-chlorine shock/oxidizer* or chlorine* to the spa water.

WATER MAINTENANCE – SCHEDULE
AS NEEDED
If water looks hazy, check PH and Total Alkilinity, and treat with chlorine*. Always refer to the
chemical manufactures dosage recommendations listed on the container. Free chlorine levels
should be maintained between 2.0 - 4.0 ppm.
These are general recommendations for water maintenance that may vary by usage and 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.
A defoamer may be used when excessive foaming occurs. Over use of a defoamer will result
in cloudy, milky water.
USE ONLY SPA CHEMICALS
Do not use chemicals designed for use in swimming pools.
With a spa you are working with a small volume of hot water compared to a large volume of
relatively cool water in a swimming pool. Because of this, chemicals will have a shorted life span
and bacteria can grow more quickly than in a swimming pool. A spa is less forgiving then 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. Always refer to the chemical manufactures dosage recommendations listed on the container.
*SPECIAL NOTE:
We recommend a minimum level of 2.0 ppm residual free chlorine be maintained in spa water. Always refer to
the chemical manufacturer’s dosage recommendations listed on the container.

Regular Maintenance Procedures
NOTE: These maintenance procedures are the responsibility of the spa owner to perform. These
procedures are not covered by the spa warranty.
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 or as necessary. Heavy bather load
will require cleaning it more often.
DRAINING YOUR SPA
The spas are equipped with a drain assembly which can be located on the front side of the spa
behind the skirt (same side as the topside control panel or where most of the spa equipment is
located). The drain will be located in the equipment area behind the front skirt panel (Figure 1).
Figure 1 Figure 1.1
Step 1: Remove the front skirt panel by removing its panel screws. The drain will be located inside
the equipment bay (see Figure 1 & Figure 1.1).
Step 2: To start the flow of water with this drain assembly; remove the cap, twist the face
counterclockwise and pull out slightly on the face. A garden hose can be attached to the
end of the drain assembly, if so desired.
NOTE:
• With the cap removed from the drain; water may drip or weep from the drain. This is normal. Be
sure that the steps are followed in reverse order when draining is finished. Make sure that the
drain cap is reattached and the valve is put back to the fully closed position so that there is no
water leaking from the drain assembly.
• Draining times will vary by model using the drain assembly. A sump pump may also be used to
expedite the draining of the spa.
25DO NOT DIVE.
REGULAR MAINTENANCE PROCEDURES
SPA SURFACE CARE
• Clean the spa shell, jets and other controls with a soft cloth and spa shell cleaner to help remove
residue and buildup on the shell surface. For mineral based buildup, white vinegar or mild scale
remover product may be necessary to use with a soft cloth for removal. Consult with your local
Master Spas dealer for proper spa cleaning products.
• Rinse the cleaned surfaces with fresh water from your garden hose and wipe with soft cloth as
doing so to help remove residual cleaning agents as some may cause foaming to occur in the
water once refilled.
• Always use an approved insulating spa cover by Master Spas to cover your spa when not in
use, especially in outdoor installations where the spa is exposed to weather conditions and sun.
Constant, prolonged exposure and use of unapproved or non-insulating spa cover can result in
damage to spa surface which would not be warranted.
CLEAN YOUR FILTER ELEMENTS
The filter elements are one of the most important components of your spa. Not only are they
essential for clean water, but they also extend the life of the spa equipment. Your filter elements
should be cleaned on a regular basis, at least once a month on average with normal usage. With
heavy use, poor water quality and/or high dissolved solid content in water; the filters may need to
be cleaned more often.
• Turn off the spa before servicing filters. Never leave to the spa running when removing the
filters. Debris can be pulled into the plumbing system and cause unwarranted damage.
• Remove filter element(s).
• With a garden hose, spray each element under pressure. Monthly, the standard filter elements
should be soaked in a filter cleaner. Check with your Master Spas dealer for details on cleaning
and/or filter replacement recommendations.
• The standard filter should be cleaned regularly and will typically last approximately 1 year. Bather
load, usage and water quality will effect the longevity of the filters and require more frequent
cleaning or replacement.
NOTE: These maintenance procedures are the responsibility of the spa owner to perform. These
procedures are not covered by the spa warranty.

REGULAR MAINTENANCE PROCEDURES
NOTE: To prevent premature failure of your spa cover and the possibility of water running out of
the spa off the bottom of the cover, always turn Laminar Flow Jets down so that they do not hit
the cover when the cover is closed. You do not want to completely turn jets off. Doing so may
cause a build up of stagnant water in the water line if not used often.
CARE OF YOUR OZONE SYSTEM
The ozone hose and check valve connecting between the ozone generator and ozone injector
should be inspected and/or replaced, if necessary, every 12 months. Depending on conditions
of the air which is being brought in to the ozone generator, the ozone hose and check valve
can wear more rapidly. This regular maintenance is not covered under the spa warranty. We
recommend that your Master Spas Dealer or Service Center be contacted to perform this type of
maintenance.
CARE OF LAMINAR FLOW JETS:
In order to keep your Laminar Flow Jets operating properly, follow these instructions in sequence:
- Turn off Laminar Flow Jets
- Remove outer ring by turning face counter clockwise
- Remove internal Jet insert with a pair of needle nose pliers
- Clean plastic filter at the back of the Jet insert so all holes are free of debris
- Reinstall Jet insert and outer ring
NOTE: These maintenance procedures are the responsibility of the spa owner to perform. These
procedures are not covered by the spa warranty.
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.
The jets in your spa can be removed for cleaning by unscrewing them
(counter clockwise) and then pulling out the jet.
TO CLEAN JETS: Place the jet(s) in a container, fully immerse in white vinegar. Let the jet(s) soak
overnight and then rinse with water. Reinstall the jet(s). It may be necessary to clean grit and
deposits from the white jet body (mounted in the spa shell) by using a small bristled brush.
28DO NOT DIVE.
REGULAR MAINTENANCE PROCEDURES
CLEANING DIVERTER VALVES
Mineral deposits, grit and sand may get into the internal parts of the diverter valves over time. The
diverter valves may become difficult to turn or not turn at all.
Remove the handle from the top of diverter valve by gently prying up on both sides of the handle
assembly at the same time.
Turn the cap piece counter clockwise. It may be necessary to put a clean towel over the cap and
turn it with a wrench.
Once loose, the cap, internal rotor assembly and handle can be pulled up out of the white
plumbing fitting.
Wipe down the internal rotor assembly that attaches to the cap and handle.
Soak the internal rotor assembly in white vinegar.
The inner wall of the white plumbing fitting should also be wiped down. If the surface of the
white plumbing has become too abrasive, you can take wet, fine sandpaper and smooth it out.
Rinse the diverter internals and reassemble.
In the future, it is helpful to turn the diverter valve only when the pump is not on. Cleaning
your diverter valve should occur every time you drain your spa. Refer to Draining Your Spa in the
Regular Maintenance Procedures section.
CARE OF YOUR SPA COVER
Always cover your spa when not in use with an approved insulating spa cover by Master Spas. 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 the cover after each use.
• 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. See cover manual
instructions for detailed instructions on proper cover care.
• 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 not part of the limited warranty provided with the spa. It is provided
through the cover manufacturer and may not be through Master Spas. Check the tags
and labeling on your cover to verify manufacturer and refer to the manufacturer’s care,
maintenance and warranty information. Your dealer can help provide you with these details.
NOTE: Always turn water feature valve down so that the water features do not hit the cover when
the cover is closed.
CARE OF YOUR SPA CABINET
The spa cabinet is made from a UV resistant material. The cabinet requires only periodic cleaning with
a stream of water from a garden hose.
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.
29DO NOT DIVE.
Regular Maintenance Procedures
NOTE: These maintenance procedures are the responsibility of the spa owner to perform. These
procedures are not covered by the spa warranty.
CARE OF YOUR SPA PILLOWS
• Your spa pillows should be rinsed periodically to remove chemical residue. This helps improve
pillow lifespan and slows down deterioration of the pillows (i.e. discoloring, becoming stiff and
flaking of the material).
• If the spa will not be used for a period of time, the pillows could be removed and rinsed to prolong their life.
NOTE: Do not cover the spa for 15 minutes after adding chemicals as the off gas can cause damage.
CARE OF STAINLESS STEEL
Master Spas uses stainless steel in a number of our spas. Its lasting beauty and resistance to
corrosion make it an excellent material for handrails and jets faces.
With the proper care it will keep its luster for many years. All stainless steel can corrode given the
right circumstances so we have provided a guide to help you keep the stainless components in
your spa looking nice.
Stainless steel derives its ability to resist corrosion by forming a very thin transparent coating on the
surface when exposed to oxygen. This coating can be damaged by abrasive materials such as steel
wool, sand paper, and other cleaning materials that are abrasive. Chlorine salts, sulfides, or other
rusting metals can also erode this thin coating exposing the metal to corrosion.
The best defense to combat corrosion on stainless steel components in your spa is make sure that
it is kept clean and free of any chemical build up.
Always:
• Clean frequently with fresh, clean water.
• Remove any rust spots as soon as they appear with vinegar or a brass, silver, or chrome cleaner.
• Use a good car cleaning wax for extra protection.
• Leave cover removed for at least 15 minutes after adding chemicals to the spa water.
Never:
• Clean with mineral acids or bleaches.
• Clean with steel wool or any other abrasive material.
• Leave in contact with iron, steel any other metals.
• Close the cover immediately after adding chemicals to the water.
NOTE: Failure to take proper care of the stainless steel could result with them rusting. Rusting is not
covered by the warranty.
NOTE: Do not cover the spa for 15 minutes after adding chemicals as the off gas can cause
unwarranted damage. Larger dosages can require longer lengths of time to off gas. It is
recommended to check spa water more frequently to allow small dosages be added as
necessary versus large dosages being added less often.

SPA TROUBLE SHOOTING GUIDE
Note: For wiring outside of U.S. and Canada, GFCI may be referred to as a RCD (residual current
device). Be sure all local electrical codes are followed.
NOTHING ON THE SPA OPERATES
1. Check the control panel display for any messages. If there is a message, refer to the diagnostic
section on that model spa. There you will find the meaning of the message and what action is
to be taken.
2. If there is no message on the control panel and the control panel is completely dark (off), try to
reset the GFCI 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, or the GFCI breaker continues to trip, contact your local Master Spas
dealer or 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. Check that all the slice valves are open.
B. Pump may need to be primed.
C. Check that the air controls are open.
Refer to Installation Instructions section. 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 on sticker located near
filter.)
3. Make sure the jets are open and the air controls are open. Refer to Glossary of Spa Technology
section.

SPA TROUBLE SHOOTING GUIDE
Note: For wiring outside of U.S. and Canada, GFCI may be referred to as a RCD (residual current
device). Be sure all local electrical codes are followed.
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 water set temperature at control panel to make sure it is set to desired temperature,
above the current water temperature.
2. Check the “heat mode” that the spa is set in. The spa should be set in the standard mode or
ready mode depending on the model.
3. Check the control panel for heat indicator. If heat indication is on, wait a reasonable amount of
time (at least 1 hour) to see if the water temperature is rising.
4. If heat indicator does not remain on, the system should be displaying a message indicating why
it can’t heat. Check the control panel for diagnostic messages. Refer to Spa Control Section
titled System Related Messages. Follow steps to alleviate message.
5. Check the control panel for light indicator. Wait a reasonable amount of time (at least 1 hour)
to see if the water temperature is rising.
6. Reset power to the spa at GFCI breaker.
7. If spa is still not heating, contact your local Master Spas dealer for service.
GFCI IS TRIPPING
A ground fault circuit interrupter (GFCI) is required by the National Electrical Code for your
protection. The tripping of the GFCI may be caused by a component on the spa or by an electrical
problem. Electrical problems include but are not limited to, a faulty GFCI breaker, spa component,
power fluctuations, and/or improper wiring. If this is a new electrical service and GFCI installation,
an instantly tripping GFCI may likely be caused by improper wiring of the load neutral from the
GFCI to the spa. It may be necessary to contact an electrician if your Master Spas dealer recommends doing so.

Winterizing & Storing Your Spa
WINTERIZING YOUR SPA
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.*
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.
1.
Due to the physical size of the spa, we recommend draining your spa with
a submersible
sump pump. Draining your spa with a conventional spa drain
is not a reasonable option.
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 face of the pump(s) where applicable.
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. A non-toxic, RV water line type
antifreeze can be used and added to jets in each seat around your spa to help prevent freeze
damage from occurring. Be sure to thoroughly flush the system before startup.
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 the spa to prevent water from entering it and check the spa periodically to be sure no
water is entering and accumulating. Spa covers are great insulator but will allow some precipitation to enter the spa. For this reason, it is highly advised to also cover the spa with a water
tight tarp while winterized. It is beneficial to keep the spa cover slightly gapped off the acrylic
shell while winterized to allow air flow in to the shell area to reduce mildew/mold buildup
caused by trapped moisture.
* If you decide to winterize your spa, we recommend that you periodically check the spa through-
out the winter to assure water is not entering the spa through or around the spa cover.
STORING YOUR SPA
The spa shell should never be left unprotected and uninsulated while being stored. Clear plastic
wrap or similar material should never be used to cover/protect the spa.
Prolonged, direct sun heat can damage the surfaces of the spa along with any components on the
spas surface. Always keep the spa covered and protected with an insulating spa cover. Resulting
damage such as cracking in the shell surface or warped or discolored components on the spa
would not be warranted.
An empty spa should never be exposed to temperatures below 0°F (-18°C) after delivery as
extreme cold can cause shell damage. This includes storage and draining (winterizing). If your spa
will be exposed to these temperatures, keep the unit filled and running. If you do not plan to use
your spa, you can set the spa to the lowest temperature setting allowed by the control system.
Failure to adhere to these guidelines may result in unwarranted damage caused to the spa.

Total bather capacity in spa. The number of bathers in spa should never exceed indicated seating capacity. Depending on
spa size, water level and bather displacement; full seating capacity may not be achievable. Do not allow additional bathers to enter if bather displacement results in water levels overflowing or reaching the spa controls (air controls, diverters,
spa topside control and etc.) as this will result in water leaking out of the spa shell and potentially in to the equipment
area.

SITE PREPARATION / GENERAL GUIDELINES
Portable spa installation is simple when properly planned. 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 consider and
measure side yard dimensions, gates, doors, overall room dimensions and vertical obstructions such as ceilings, roof overhangs, balconies and overhead cables. Any other space limiting
obstacles such as stairs, trees, and shrubs must also be evaluated. Please be sure to contact and
review these site and installation plans with your Master Spas dealer prior to delivery.
2) 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 reinforcement bars crossed throughout the pad.
IMPORTANT
When installing your spa indoors, on a wood deck, roof or balcony; load requirements need to be
evaluated before installation. You should speak with a qualified contractor or your local building
department to confirm that your surface is adequate for supporting a spa.
All sides of the spa must be accessible for regular maintenance or in the event that service is
needed. Periodical maintenance checks require entry into the equipment bay. When possible, it is
wise planning for the future to leave 3 feet of access to all sides of the spa in the event your spa
requires maintenance. Your spa warranty does not cover the cost of providing access for service.
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
• Appropriate materials and drainage around
the spa to handle water presence and runoff
GENERAL CONSIDERATIONS FOR INDOOR INSTALLATION
Installing your spa indoors creates an entirely different set of considerations.
• Work with your Master Spas dealer and
contractor to insure all local building, electrical and plumbing codes are met
• Plan for floor drains around your spa to drain
off excess water runoff that will occur during normal use and 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

SITE PREPARATION / GENERAL GUIDELINES
GUIDELINES FOR PARTIALLY OR FULLY RECESSED INSTALLATION
Spas manufactured by Master Spas are designed to be installed in a variety of settings. One of
which is installing below grade. Should a spa be installed below the level of the site drainage
system (below grade), a system for preventing water collecting and pooling must be designed
based on the requirements of the local authority having jurisdiction. The drainage system must
be designed based on things such as rainfall, water runoff, splashing, draining the spa, etc. that
could potentially feed the below grade area with water. When located in designated floodways,
additional attention to maximum water load entering the area below grade must be addressed to
prevent water from accumulating below grade at all times. It is generally recommended that the
spa be installed above grade because the spa is not designed to be submerged in water. When a
proper drainage system is designed and proper ventilation is planned based on the characteristics
of the site, installing the spa below grade is an accepted method of installation.
• The unit is self-supporting when placed on a surface designed to support the full load of the spa
(see Surface/Pad Requirements). Do not backfill with sand, gravel, or earth. Doing so will void
the warranty.
• Plan for complete drainage so that water accumulation drains away from the spa perimeter and
standing water never reaches the electrical equipment.
• Plan for appropriate ventilation to remove moisture accumulation and prevent equipment
overheat.
• Provide a minimum of 3 feet service area around the perimeter of the unit. Site access issues are
not covered by the product warranty.
• The unit is not designed to be submerged in water. Water entering the equipment area creates
many hazards and resulting damage will not be covered by the product warranty.
• Make sure that the surroundings do not create any additional hazards.
• Surfaces placed around the unit should also be evaluated for walking/slipping hazards from
standing water. Proper drainage is vital to the installation of a below grade installation.
• Check all building, electrical, and plumbing codes with the authority having jurisdiction to ensure
that your installation is in compliance with all local codes.
• Additional consideration needs to be made when installing unit in designed floodways.
• Verify that site specific drainage systems such as down spouts are not going to feed the area
below grade.
• Below grade drainage system needs to be evaluated based on area specific rainfall. One size
does not fit all so an analysis by a qualified, local engineer to ensure proper drainage of all sources of water is a must when installing below grade.

ELECTRICAL 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 codes regulated by the authority
having jurisdiction at the time of installation.
These connections must be made in accordance with the wiring diagrams found
inside the control box and in this manual. This equipment has been designed to
operate on and requires 230V, 50Hz service. Make sure that power is not applied
while performing any electrical installation. A bonding lug for bonding copper wire
has been provided on the electrical equipment pack to allow connection to local
ground points. The ground wire must be at least 8 AWG (8.36mm2 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. The supply wiring to the spa must utilize a symmetrically grounded system. The spa must not be
wired to electrical systems utilizing no ground (IT) or TN-C grounding. Be sure
to have a licensed electrician examine and ensure proper grounding is provided.
See chart on next page for wire size conversion. All Master Spas equipment packs
are wired for 230 VAC only. The only electrical supply for your spa must include
a switch or circuit breaker to open all non-grounded supply conductors to comply
with BS7671 (or other local jurisdiction code or law). The disconnect must be
readily accessible to the spa occupants, but installed at least five feet from the spa.
Residual Current Device (RCD) must be used to comply with this manual, BS
7671, or any local electrical code or law requirements. A residual current is a current leak from any one of the supply conductors to ground. An RCD is designed
to automatically shut off power to a piece of equipment when a ground fault is
detected.
Route the cable into the equipment area for final hook-up to terminals inside
the control pack or junction box. The spa must be hooked up to a “dedicated”
breaker(s) and RCD. 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.

A residual current device (RCD, or R.C.D. henceforth) is the generic term for a device that monitors
the current in the line conductor and the neutral conductor in an earthed system.
In a circuit that’s operating properly, the vector sum of the live and neutral current values added
together will be zero. Current flowing to earth, due to a line earth fault, will return via the earth
conductor, and regardless of load conditions, will be registered as a fault. This current flow will
give rise to a residual current that will be detected by the device. If the residual current exceeds the
rated sensitivity of the RCD, it will automatically activate a tripping of the faulty circuit.
Two Pole RCD Four Pole RCD
Typical specifications are as follows:

INitial Spa Setup
1. Put spa in final position that allows for access to equipment and spa components. Master
Spas recommends that at least 3 feet of space be provided around all sides of the spa for
access. This provides adequate space for regular maintenance and service.
2. Remove front skirt panel (this is the side where the topside control panel is located) so
electrical can be hooked up to the spa control system. This panel is removed by unscrewing
the screws securing the skirt corners and the front skirt panel.
3. With the front skirt panels removed allowing access to the equipment, 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. The slice valves may become closed during transportation of the
spa.
4. Fill spa at least 1” above the filters or to the minimum water level indication located near the
filter area. We recommend filling the spa through the filter area.
5. Turn the power on to the spa. Spa will initially display Priming Mode or “Pr”. This lasts
approximately 5-6 minutes. This time is provided to allow each of the pumps to be activated
and checked to ensure they are not air locked from the spa being filled.
6. Be sure the adjustable jets in your spa are open by turning the face of the jet. Most of the jets
in your spa are adjustable and removable by turning the face of the jet.

7. It may be necessary to bleed air from the pump(s) in your spa if, after start up, your spa
pumps are turning on and off but you do not have water flow from the jets in your spa.
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 and
service charges may apply.
To relieve an airlock situation, loosen the pump union on the discharge of the pump. This
pump union is indicated by an arrow in the picture below. Water should leak out of the
union once the air has been removed. Tighten the union and test the pump for proper operation. Repeat this process if needed.

8. Adjust water chemistry according to the instructions provided in the “Water Maintenance”
section.
9. Your spa water will heat approximately 3 to 4 degrees Fahrenheit per hour (1 to 2 degrees
Celsius) with the cover placed on the spa. This varies depending on the size of the spa and
ambient temperatures.

PROGRAMMING, ETC.
The Settings Screen is where all programming and other spa behaviors are controlled.
Each icon on the Settings screen takes you to a different screen, where one or more setting may be
viewed and/or edited.
DUAL TEMPERATURE RANGES (HIGH VS. LOW)
This system incorporates two temperature range settings with independent set temperatures. The
specific range can be selected on the Settings screen and is visible on the Main Screen in the upper
left corner of the display.
These ranges can be used for various reasons, with a common use being a “ready to use” setting
vs. a “vacation” setting. Each range maintains its own set temperature as programmed by the user.
This way, when a range is chosen, the spa will heat to the set temperature associated with that
range.
High Range can be set between 80˚F (27˚C) and 104˚F (40˚C).
Low Range can be set between 50˚F (10˚C) and 99˚F (37˚C).
Freeze Protection is active in either range.
The Heat Icon
takes you to a
screen where you control the Heat
Mode and the Temperature Range.

HEAT MODE – READY VS. REST
In order for the spa to heat, a pump needs to circulate water through the heater. The pump that
performs this function is known as the “heater pump.”
The heater pump can be either a 2-speed pump (Pump 1) or a circulation pump.
If the heater pump is a 2-speed Pump 1, Ready Mode will circulate water every 1/2 hour, using
Pump 1 Low, in order to maintain a constant water temperature, heat as needed, and refresh the
temperature display. This is known as “polling”.
Rest Mode will only allow heating during programmed filter cycles. Since polling does not occur, the
temperature display may not show a current temperature until the heater pump has been running
for a minute or two.
When the heater pump has come on automatically (for example for heating) you can switch between low speed and high speed but you cannot turn the heater pump off.
Circulation Mode (See information within "Pumps" in the Spa Controls - Spa Behavior section, for
further information on circulation modes)
If the spa is configured for 24hr circulation, the heater pump generally runs continuously. Since the
heater pump is always running, the spa will maintain set temperature and heat as needed in Ready
Mode, without polling.
In Rest Mode, the spa will only heat to set temperature during programmed filter times, even
though the water is being filtered constantly when in 24hr circulation mode.
READY-IN-REST MODE
Ready in Rest Mode appears in the display if the spa is in Rest Mode and the Jets 1 Button is
pressed. When the heater pump has come on automatically (for example for heating) you can
switch between low speed and high speed but you cannot turn the heater pump off. After 1 hour,
the System will revert to Rest Mode. This mode can also be reset by selecting the Heat Mode.
57DO NOT DIVE.
PRIMING THE PUMPS
As soon as the Priming Mode screen appears on the
panel, select the “Jets 1” button once to start Pump 1
in low-speed and then again to switch to high-speed.
Also, select the other pumps, to turn them on. The
pumps should be running in high-speed to facilitate
priming. If the pumps have not primed after 2 minutes,
and water is not flowing from the jets in the spa, do
not allow the pumps to continue to run. Turn off the
pumps and repeat the process. Note: Turning the
power off and back on again will initiate a new pump
priming session. Sometimes momentarily turning the pump off and on will help it to prime. Do not
do this more than 5 times. If the pump(s) will not prime, shut off the power to the spa and call for
service.
Important: A pump should not be allowed to run without priming for more than 2 minutes. Under
NO circumstances should a pump be allowed to run without priming beyond the end of the 4-5
minute priming mode. Doing so may cause damage to the pump and cause the system to energize
the heater and go into an overheat condition.
Spa Controls
Fill it up!
PREPARATION AND FILLING
Fill the spa to its correct operating level. Be sure to open all valves and jets in the plumbing system
before filling to allow as much air as possible to escape from the plumbing and the control system
during the filling process. After turning the power on at the main power panel, the top-side panel
will display a splash screen or startup screen.
PRIMING MODE – M019*
After the initial start-up sequence, the control will enter Priming Mode and display a Priming Mode
screen. Only pump icons appear on the priming mode screen. During the priming mode, the heater
is disabled to allow the priming process to be completed without the possibility of energizing the
heater under low-flow or no-flow conditions. Nothing comes on automatically, but the pump(s) can
be energized by selecting the “Jet” buttons. If the spa has a Circulation Pump, it can be turned on
and off by pressing the “Circ” button during Priming Mode.
EXITING PRIMING MODE
The system will automatically enter the normal heating and filtering at the end of the priming
mode, which lasts 4-5 minutes. You can manually exit Priming Mode by pressing the “Back” button
on the Priming Mode Screen. Note that if you do not manually exit the priming mode as described
above, the priming mode will be automatically terminated after 4-5 minutes. Be sure that the
pump(s) have been primed by this time. Once the system has exited Priming Mode, the top-side
panel will display the Main Screen, but the display will not show the water temperature yet, as
shown below. This is because the system requires approximately 1 minute of water flowing through
the heater to determine the water temperature and display it.

Spa Behavior
PUMPS
On the Spa Screen, select a “Jets” button once to turn the pump on or off, and to shift between
low- and high-speeds if equipped. If left running, the pump will turn off after a time-out period.
Non-Circulation Systems
The low-speed of pump 1 runs when the blower or any other pump is on. If the spa is in
Ready Mode, Pump 1 low may also activate for at least 1 minute every 30 minutes to detect
the spa temperature (polling) and then to heat to the set temperature if needed. When the
low-speed turns on automatically, it cannot be deactivated from the panel, however the
high speed may be started.
Circulation Pump Modes
If the system is equipped with a circulation pump, it will be configured to work in one of two different
ways depending on the control system software. The circulation pump mode cannot be changed.
1. The circulation pump operates continuously (24 hours) with the exception of turning off for 30
minutes at a time when the water temperature reaches 3°F (1.5°C) above the set temperature
(most likely to happen in warm climates or if set temperature is lowered/set below the current
water temperature). This is the typical mode for most spas with a dedicated circulation pump.
2. A programmable circulation pump will come on when the system is checking temperature (poll-
ing), during filter cycles, during freeze conditions, or when another pump is on.
FILTRATION AND OZONE
On non-circulation systems, Pump 1 low and the ozone generator will run during filtration.
On circulation systems, the ozone will generally run with the circulation pump.
The system is factory-programmed with one filter cycle that will run in the evening (assuming the
time-of-day is properly set) when energy rates are often lower. The filter time and duration are
programmable. A second filter cycle can be enabled as needed.
At the start of each filter cycle, the pumps will run briefly to purge the plumbing to maintain good
water quality.

Spa Behavior
FREEZE PROTECTION
If the temperature sensors within the heater detect a low enough temperature, then the water
devices automatically activate to provide freeze protection. The water devices will run either
continuously or periodically depending on conditions.
CLEAN-UP CYCLE (OPTIONAL)
When a pump is turned on by a button press, a clean-up cycle begins 30 minutes after the pump
is turned off or times out. The heat/filter pump and the ozone generator will run for 30 minutes or
more, depending on the system. If the spa has a 24hr circulation pump which performs as the heat
and filter pump, the cleanup cycle will not apply as the 24hr circulation pump provides constant
filtration. On some systems, you can change this setting. See the Cleanup Cycle section in
Additional Settings.

Adjusting Filtration
PURGE CYCLES
In order to maintain sanitary conditions, as well as protect against freezing, all pumps will purge
water from their respective plumbing by running briefly at the beginning of each filter cycle.
If the Filter Cycle 1 duration is set for 24 hours, enabling Filter Cycle 2 will initiate a purge when
Filter Cycle 2 is programmed to begin.
THE MEANING OF FILTER CYCLES
1. The heating pump always runs during the filter cycle*
2. In Rest Mode, heating only occurs during the filter cycle
3. Purges happen at the start of each filter cycle
* For example, if your spa is set up for 24/hour circulation except for shutting off when the
water temperature is 3˚F/1.3˚C above the set temperature, that shutoff does not occur during
filter cycles.

The installer can use the GFCI Trip Test to confirm proper function of the GFCI.
The GFCI should trip within several seconds and the spa should shut down. If it does not, shut
down the power and manually verify that a GFCI breaker is installed and that the circuit and spa are
wired correctly. Verify the function of the GFCI with its own test button. Restore power to the spa
and repeat the GFCI Trip Test.
Once the GFCI is tripped by the test (causing the spa to be shut off from power being removed),
reset the GFCI breaker to turn spa back on. You can verify a successful test by navigating to the
above screen. “Passed” should appear after the Reset line is selected on the GFCI screen.
CE Product:
CE registered systems do not have an RCD Test Feature due to the nature of the electrical service.
