The electrical circuit must be installed by a certified
electrician and approved by a local building or
electrical inspector.
BASIC INFORMATION
WATER CARE
IMPORTANT: Caring for your water by ensuring
proper chemical usage is the single most important
thing you can do to keep your swim spa in good
condition.
WARNING: Improper chemical usage and maintenance
will quickly lead to severe issues with your spa and can
affect the spa equipment, jets, pumps, and all other
components in contact with the spa water.
All spas and swim spas are susceptible to
damage from unbalanced spa water.
Always maintain your water chemistry within the following
parameters.
pH
7.2 - 7.8
Chlorine
1.0 - 3.0 ppm
Bromine
2.0 - 5.0 ppm
Total Alkalinity
100 - 120 ppm
Calcium Hardness
150 - 250 ppm
ELECTRICAL
All self-contained spas use 120VAC or 240VAC electrical spa packs.
120VAC: Requires an isolated 15 Amp circuit breaker,
an isolated circuit with no other appliances or lights on
the circuit at any time. Extension cords are not to be
used in conjunction with the operations of the swim spa.
Low voltage damage could result, and this is not covered
under warranty. IMPORTANT: Spas with 110V means
that the jets and heaters will not work at the same
time.
NOTE: All components must be 120V. No 240V
components allowable.
240VAC: Depending on the model of the spa, it
will require either a 40, 50, or 60 Amp dedicated
circuit breaker with the proper wire size (gauge)
based on the length of the run.
SURFACE
Your new portable swim spa must be placed on a firm, flat and level surface, so that the weight is supported uniformly.
We recommend no less than a 3” (93 mm) thick concrete slab. Wood decking or balconies must be constructed to
support 150 pounds per square foot (730 kg/m2). Refer to the local and current building codes in your area. Should
your new swim spa need to go through the gate or space –restricted area, ensure you’ve communicated those
limitations with your dealer to avoid delivery complications.
NOTE: Damage caused by alternate decking methods may void the spa warranty. Contact your dealer if you
have any questions regarding spa location and placement.
TRANSPORT
Your new swim spa has left the factory cleaned and polished and ready to begin operation after passing our many
quality and operational tests. However, depending on your location in the world, your swim spa may have spent days or
even weeks in transit before arriving at your home. Please ensure that before filling or operating your spa that you check
all electrical and plumbing connections are securely connected in the equipment area as they might have loosened
during shipping. If any dirt has accumulated, you will want to remove it with a clean cloth or sponge using warm water.
! PLEASE READ YOUR ENTIRE OWNER’S MANUAL BEFORE SPA OPERATION !

IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
DANGER: Risk of Injury. The suction fittings in this swim 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 the spa
if the suction fittings are broken or missing. Never replace a
suction fitting with one rated less than the flow rate marked on
the original suction fitting.
DANGER: Risk of Accidental Drowning. Do not allow children to
be in or around the swim spa without adult supervision. Keep the
swim spa cover on and locked when not in use. See instructions
enclosed with the cover for locking procedures.
DANGER: Risk of Electrical Shock. The electrical supply for this
product must include a suitably rated switch or circuit breaker to
open all ungrounded supply conductors to comply with section
422-20 of the National Electrical Code, ANSI/NFPA 70. The
disconnect must be readily accessible and visible to the spa
occupant but installed at least 5 feet (1.5 m) from the swim spa
water.
READ,FOLLOW ANDSAVETHESEINSTRUCTIONS
a) A green colored terminal or a terminal marked G, Gr,
Ground, Grounding, or the symbol * is located inside the
supply terminal box or compartment. To reduce the risk of
electric shock, this terminal must be connected to the
grounding means provided in the electric supply service panel
with a continuous copper wire equivalent in size to the circuit
conductors that supply this equipment.
b) At least two lugs marked “Bonding Lugs” are provided on
the external surface or on the inside of the supply terminal box
compartment. To reduce the risk of electric shock, connect the
local common bonding grid around the spa to these terminals
with an insulated or bare copper conductor no smaller than
No. 6 AWG.
c) All field-installed metal components such as rails, ladders,
drains or other similar hardware within 5 feet (1.5 m) of the spa
shall be bonded to the equipment grounding bus with copper
conductors no smaller than No. 6 AWG.
WARNING: To Reduce the Risk of Injury: 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.
Since excessive water temperatures have a high potential for
causing fetal damage during the early months of pregnancy,
pregnant or possibly pregnant women should limit spa water
temperatures to 100 °F (38 °C). If pregnant, please consult your
physician before using a spa. Before entering the spa, the user
should measure the water temperature with an accurate
thermometer since the tolerance of water temperature regulating
devices may vary as much as +/- 5 °F (2 °C). Persons suffering
from obesity or a medical history of heart disease, low or high
blood pressure, circulatory system problems or diabetes should
consult a physician before using the spa.
CAUTION: Risk of Hyperthermia: Hyperthermia occurs when the
internal temperature of the body reaches a level several degrees
above the normal body temperature of 98.6 °F (37 °C). The
symptoms of hyperthermia include drowsiness, lethargy, and an
increase in the internal temperature of the body. Prolonged
immersion in hot water may induce hyperthermia. A description
of the causes, symptoms, and effects of hyperthermia are as
follows:
• Unawareness of impending hazard;
• Failure to perceive heat;
• Failure to recognize the need to exit spa;
• Physical inability to exit spa;
• Fetal damage in pregnant women; and
• Unconsciousness and danger of drowning.
WARNING: Children should not use the spa without adult
supervision.
WARNING: Do not use the spa unless all suction guards are
installed to prevent body and hair entrapment.
WARNING: People with infectious diseases should not use a
spa.
WARNING: To avoid injury, exercise care when entering or
exiting the spa.
WARNING: Do not use drugs or alcohol before or during the
use of a spa to avoid unconsciousness and possible drowning.
The use of alcohol or drugs can greatly increase the risk of fatal
hyperthermia in spas.
WARNING: Pregnant or possibly pregnant women should
consult a physician before using a spa.

WARNING: Water temperature more than 38 °C (100 °F) may be
injurious to your health. Before entering the spa, measure the
water temperature with an accurate thermometer.
WARNING: Do not use the spa immediately following strenuous
exercise.
WARNING: Prolonged immersion in a spa may be injurious to
your health.
WARNING: Do not permit electric appliances (such as lights,
telephone, radio, television, etc.) within 5 feet (1.5m) of the swim
spa unless such appliances are built-in by the manufacturer.
WARNING: People using medication and/or having an adverse
medical history should consult a physician before using a swim
spa.
WARNING: Maintain water chemistry in accordance with the
manufacturer’s instructions.
WARNING: The equipment and controls shall be located no
less than 1.5 meters horizontally from the swim spa.
CAUTION: Observe a reasonable time limit when using the swim
spa. Long exposures at higher temperatures can cause high
body temperature. Symptoms may include dizziness, nausea,
fainting, drowsiness, and reduced awareness. These effects
could possibly result in drowning.
CAUTION: Enter and exit the swim spa slowly. Wet surfaces can
be very slippery.
CAUTION: Proper chemical maintenance of swim spa water is
necessary to maintain safe water and prevent possible damage
to swim spa components. Maintain water chemistry in
accordance with manufacturer’s instructions.
CAUTION: Use the straps and clip tie downs to secure the cover
when not in use. This will help to discourage unsupervised
children from entering the swim spa and keep the swim spa
cover secure in high-wind conditions. There is no representation
that the cover, clip tie-downs, or actual locks will prevent access
to the swim spa.
CAUTION: For exercise, the water should not exceed 90 °F (32 °
C).
GLOSSARY OF TERMS
AIR CONTROL: Mounted generally on the lip of the
swim spa, it induces warm air from the equipment
enclosure into the jet stream through venturi action.
WATER DIVERTER: The large diverter is used to
divert water to various seats in the swim spa.
FILTER AIR RELIEF VALVE: Located on top of
filter housing. Used to release air from the filter.
SKIMMER BLEEDER VALVE: Located inside the
skimmer area or on the spa wall, needs to be
loosened while filling the spa. This will help
eliminate air from being trapped in the spa
equipment.
OZONATOR: Available as an option. The ozonator
produces natural ozone through the Corona
Discharge process. Continuous use of an ozonator
can dramatically reduce sanitizer consumption.
CONTROL BOX (PACK): Basically the “heart” of
the spa. Power is distributed to any/all functions of
the spa: pumps, ozonator, LED lighting, heater
element, etc.
CONTROL PANEL: Mounted on the top lip of
the spa and controls the functions of the spa.
EQUIPMENT ENCLOSURE: An enclosure that
houses the control box, pump(s) and other electrical
components.
FILTER: The filter cleans the spa by passing water
through a filter cartridge where debris and impurities
are removed. Top load filter means the filter
cartridge is accessible through the top of the spa.
Front access skimmer means cartridge is accessed
through door of skimmer.
DISCLAIMER: The pictures displayed above are for reference purpose only. Some parts may be different depending upon
the spa model.

FLOOR DRAIN: The floor drain is covered by a grate-
type cover and is utilized when draining the spa. It also
acts as the return for the ozonator. You will see bubbles
emitted from this drain, which is the result of water
mixing with the ozone output.
GATE VALVES: Red with a grey handle is located at
the inlet and outlet of the pumping system. Used while
servicing spa equipment, the valves open or close the
water flow to the equipment. To remain open for normal
use, turn fully counterclockwise.
KNIFE VALVES: A white “T”-handled valve, same
functions as Gate valve (see above), except to open
them you pull up on handle.
HEATER: The electronically controlled heater raises
the temperature of the spa to the desired setting.
LEDs: LEDs and their special lenses can be used to
achieve the desired mood lighting in the spa and spa
jets.
SKIMMER: This is the rectangular outlet at the water
level. The skimmer removes surface debris from the
filter. The water level in the spa should be kept ½ to ¾
up on the skimmer for optimum operation.
SUCTION: During operation of the equipment, the
suction works in conjunction with the skimmer to draw
water from the bottom of the spa through the filter,
keeping the spa sparkling clean.
NECK JET: Direction-controllable jet for soothing neck
massage.
ADJUSTABLE CLUSTER JET: Our adjustable, high-
intensity hydrotherapy jet.
DIRECTIONAL JET: Provides a straight flow for a
therapeutic massage.
ROTATIONAL JET: Provides a Unidirectional
circular therapeutic massage.
MASSAGE JET: Delivers massage in staccato
bursts over a narrow, focused area.
VOLCANO/WHIRLPOOL JET: high-output jet
designed for foot and leg massage.
LAMINAR FLOW: A thin stream of water that arcs
from the spa lip.
PREPARATION, SET-UP, AND LOCATION
FOR YOUR NEW SPA
• You want to keep in mind how you intend to use the spa
and plan the location accordingly.
• How close is the spa from the exit or entrance to your
house? (Consider the cold weather)
• Is the path to your spa clean of debris, sand, grass? (So as
not to track into the spa).
• Is there protection from wind, inclement weather?
• Can neighbors or passersby see the spa?
NOTE: Allow for service access: Many swim spa owners
enjoy placing their spa in a decorative enclosure or a deck.
Keep in mind that you need to have access to equipment for
maintenance and the swim spa should be able to be moved or
lifted without destroying the special enclosure or its
surroundings. You should discuss this with your dealer when
designing the location. Extension cords are not to be used in
conjunction with the operations of the spa. Low voltage
damage could result, and this is not covered by warranty.
DISCLAIMER: The pictures displayed above are for reference purpose only. Some parts may be different depending upon
the spa model.

1300 PLUNGE - SAFE HANDLING / UNLOADING INSTRUCTIONS
CAUTION!
•Use 6" wide straps that are at least 30 feet in length to support the base of the swim spa
during lifting.
•Ensure the straps are in good working condition prior to unloading the swim spa (ie. No
rips, wear, or tear).
•Ensure the straps are evenly spaced at 30" from each end (see diagram below). Spacing
the straps may require slight adjustments to ensure the load is balanced.
•The chains attached to the crane must be a minimum of 18 feet in length from the point of
lifting. Using chains smaller than 18 feet will add stress to the outer lip of the swim spa and
may result in damage.
•Using the appropriately weighted straps and chains is important to ensure the safe
handling of the 1300 PLUNGE Swim Spa. Please consult your crane operator for
more information.
Note: Damage during transportation or from mishandling or improper lifting is not covered by the CSMI Warranty.
Note: Never lift or handle the spa with swim plumbing or equipment.

SPACARE GUIDE
Your Authorized Dealer carries a wide variety of care and
maintenance products. For more information, please contact your
Dealer.
REQUIRED FILTERMAINTENANCE
Your new swim spa is equipped with a filter cartridge. To always
ensure maximum water quality, you should replace the filter
cartridge every six months, or earlier as necessary. The filter
cartridge is designed to be thrown away! Attempts to reuse the
filter cartridge may result in the re-release of unwanted particles
back into the spa.
PLEATCODUALCOREFILTERS
Your spa comes with a premium filter. Most come equipped with a
Pleatco DualCore Filter, which does a better job of cleaning your
spa water than any other filter cartridge. The DualCore filter has
two layers of filtration media, the outer layer, and the inner layer.
Both are engineered to remove different particles from your water.
The outer core is like a traditional filter which traps larger debris,
while the inner core filters the water for particles down to 3 microns
in size. The inner core is easily removed and both filter media can
be cleaned.
Keeping your spa water clean and refreshing is extremely
important for your enjoyment of your swim spa. Our spas come
with only the best filters available to ensure your satisfaction.
REQUIRED WATER REPLACEMENT
You should replace the spas water every 3-6 months. The
frequency will depend on several variables including frequency of
use, number of bathers and attention paid to the water quality
maintenance. You will know it is time for a change when you can
no longer get the normal feel or sparkle to the water, even though
the key water balance measurements are all within the
recommended ranges.
HEADREST /PILLOW CARE
The pillows can be removed for easy cleaning and
maintenance. All pillows have plugs within the pillow itself. To
remove the pillow, grab the bottom edge firmly and pull
outward. This will allow the pillows to pop out from the
receptacle in the spa shell. To reinstall the pillow, you will align
the pillow plug with the receptacle. Press/hit the front side of
the pillow firmly, which will insert the plug back into the
receptacle.
•Proper water chemistry must be maintained. Your swim
spa pillows are easily and quickly damaged when
exposed to unbalanced spa water. If you suspect that
your chemicals may be unbalanced, remove your pillows
immediately until the water has been restored to the
suggested condition.
•Do not sit on the pillows.
•Do not pull on the pillows.
•Pillows should be cleaned using a soft cloth and mild
soap, then wiped with a conditioner. We recommend that
pillows be washed each time you drain your spa.
This Limited Warranty is void if failure is caused by accident,
acts of nature, acts of God, or other causes beyond the control
of CSMI. Neglect, misuse, and abuse include any installation,
operation, or maintenance of the spa other than in accordance
with the instructions contained in the owner’s manual provided
with the spa, including, but not limited to damage caused by
operation outside the range of 34 °F and 116 °F or 1 °C and 47
°C.
Please be advised that the Spa Warranty will become void if
Coast Spas or any of its selling or servicing agents determines
that the spa has been exposed to Hydrogen Peroxide, TriChlor
or any substance using it as an ingredient proven to be
dangerous to the Spa. Any condition arising from the use of
Hydrogen Peroxide or TriChlor on the Spa is not a warrantable
defect.
SWIM SPA INTERIOR
Your swim spa has a fiberglass reinforced acrylic shell.
Generally, dirt and stains will not adhere to the surface. To
properly clean the surface, we recommend wiping it with a soft
damp cloth (or sponge) using a low sudsing household soap or
liquid detergent and rinsing thoroughly with fresh water.

PLUNGE SPA
OWNER’S MANUAL
2023
13
OPEN
OPEN
Stubborn dirt or stains may be removed by using Spic & Span
adequately dissolved in water. Contact your dealer and inquire
about maintenance packages.
DO NOT use any cleaning products containing abrasives or
solvents, since these could damage the surface. Harsh
chemicals should never be used on acrylic surfaces. Damage to
the shell due to the use of harsh chemicals is not covered under
the warranty.
DO NOT leave your swim spa drained and in direct sunlight for
extended periods of time. Extreme heat could cause damage to
the acrylic surface and may induce an effect known as “crazing”.
Crazing is not covered under the spa limited warranty.
STAINLESS STEEL CONTROLS AND COMPONENTS
ABOVE THE WATER LINE
To preserve the stainless-steel finish of the controls and
components above the water line, we recommend they be wiped
with a dry soft cloth after each use of your swim spa. In
addition, off-gas your tub by removing the cover for
approximately 30 minutes multiple times per week (if not in use)
and after every shock treatment.
CABINET CARE
Never spray cabinets with a high-pressure garden hose or
pressure washer for any reason. This action may induce an
electrical short in the swim spa’s electrical equipment.
VINYLCABINET
Vinyl cabinets are made of a rigid polymer that combines the
durability of plastic with the beauty of real wood. This cabinet is
manufactured so that it won’t crack, peel, blister or delaminate
even after prolonged exposure to the elements. We recommend
wiping the cabinet with a soft damp cloth (or sponge) using
household soap or liquid detergent and rinsing with fresh water
thoroughly. DO NOT use abrasive cleansers or material as this
may damage the surface.
Vinyl cabinet door opening instructions
COVER CARE
A well cared for spa cover is a thing of beauty. Be sure to clean
and condition your cover at least once a month –more often if
needed.
Your cover needs to be cleaned and conditioned because vinyl
can be dry and become brittle, spoiling your spa’s appearance.
Dry, brittle vinyl can also tear at the seams and stress points.
Quality materials, internal sewn reinforcing and careful
workmanship can only go so far against the ravages of Mother
Nature. See the specific Warranty card enclosed with your cover
for further details.
•When you shock your spa, you need to remove the cover for
a minimum of 30 minutes to ensure that the chemical gas
off can escape from the spa.
•You are required to keep the spa covered at all times when
not in use to protect the shell from harmful UV rays.
•A covered spa will use less electricity when maintaining
the desired water temperature.
•See the manual that comes with the cover for proper
mounting of the cover locks.
•The cover should always remain locked to prevent
unauthorized entry into the spa and potential drowning.
•Do not Sit, Stand or Lie on your cover. Nor should you
place any heavy object on top of the cover as this may
damage the structure.
VERY IMPORTANT: We recommend a vinyl conditioner for your
spa cover. Your local dealer carries a wide variety of care and
maintenance products. Choose a pleasant day each month to
remove your cover from the spa and lay it on a flat
surface accessible by garden hose.
Douse the cover with a healthy amount of water from the hose or a
bucket to rinse away loose dirt or debris. Using a soft bristle brush
and a mild solution of dishwashing liquid (about one teaspoon of
detergent to two gallons of water), and with a gentle circular
motion, scrub the cover clean. Be careful not to let any areas of
the cover dry before they’re thoroughly rinsed. Now apply the vinyl
conditioner as directed on the container. Massage the conditioner
into the cover in a gentle but firm manner. Before replacing the
cover on your spa, wipe and rinse any dirt from the bottom of the
cover. When you are ready, put the cover on the spa. NOTE: To
remove tree sap, use lighter fluid (not charcoal lighter but the fluid
used in cigarette lighters). Use sparingly, then immediately apply
conditioner to that area.
All waterfalls and laminar flow water features should be turned off
when the spa is not in use to avoid heat and water loss.

BASIC INSTALLATION AND CONFIGURATION
GUIDELINES
WARNING! Qualified Technician Required for Service and
Installation
ELECTRICAL REQUIREMENTS
All self-contained spas use 120VAC or 240VAC electrical spa packs.
These instructions describe the only acceptable electrical wiring
procedures. Spas wired in any other way will void your warranty and
may result in serious injury. All installations should be completed
by a certified electrician. Failure to comply with state and local
codes may result in fire or personal injury and will be the sole
responsibility of the spa owner.
120VAC: This requires an isolated 15 Amp circuit breaker. This
needs to be an isolated circuit with no other appliances or lights on
this circuit at any time. Extension cords are not to be used in
conjunction with the operations of the spa. Low voltage damage
could result, and this is not covered by warranty. NOTE: All
components must be 120V; No 240V components allowable.
240VAC: Depending on the model of spa, it will require either a 40
Amp, 50 Amp, or 60 Amp dedicated circuit breaker, GFCI, with
the proper wire size based on the length of the run. The
electrical circuit must be installed by a certified electrician and
approved by a local building or electrical inspector.
OPTIONAL AUXILIARY HEATER
Your spa (if opted) may be equipped with two heater assemblies
(main heater and auxiliary heater). The auxiliary heater requires a
separate 30 AMP breaker service.
DISCLAIMER: There are no user serviceable parts in the GFCI
compartment. All the services and repairs should be performed by
a certified electrician only.
Use minimum 6AWG copper conductors only. Torque field
connections between 21 and 23 in lbs. Readily accessible
disconnecting means to be provided at time of installation.
Permanently connected power supply
Connect only to a circuit protected by a Class A Ground Fault
Circuit Interrupter (GFCI) or Residual Current Device (RCD)
mounted at least 5’ (1.52M) from the inside walls of the spa and in
line of sight from the equipment compartment.
CSA ENCLOSURE: TYPE 2
Refer to Wiring Diagram inside the cover of the control enclosure.
Refer to Installation and Safety Instructions provided by the spa

SWIMSPAMAINTENANCEPROCEDURES
FILTER MAINTENANCE
The swim spa filter is one of the most important maintenance
items of a spa. The filter is there to remove debris from the
water and needs to be cleaned on a regular basis. Failure to do
so may result in poor performance, poor water clarity and could
prevent the spa from heating. Filtration starts as soon as flow is
steady through the filter. As the filter cartridge removes the
debris from the spa water, the accumulated debris causes flow
resistance.
CLEANING AND REPLACING FILTER CARTRIDGE
Your swim spa filter has been designed for quick and easy
maintenance. The filter cartridge should be rinsed by hose once
a week and cleaned with a cartridge cleaner once a month. A
second filter cartridge is recommended and will speed up this
process. This can be purchased from your local dealer.
TOPLOAD FILTERS
•Turn the power OFF at the breaker.
•Loosen air relief valve, then remove retainer ring.
•Pull filter lid straight up to remove.
•Do not twist or pull the filter lid up at an angle. This
could cause damage to the filter canister, especially
in freezing conditions.
•Remove filter cartridge and clean with a garden hose
and a high-pressure nozzle. Periodically you may need to
soak your filter in a “cartridge filter cleaner” to remove
excess minerals and/or oils.
•Rinse filter thoroughly before installing. Clean O-ring on
filter lid and apply a light film of silicone lubricant to the O-
ring. Do not use petroleum-based lubricant as it could
damage the O-ring. Consult your dealer to purchase
suitable lubricant.
•Place clean Cartridge in filter canister.
•Replace filter lid and re-tighten retaining ring (finger tight
only).
NOTE: Make sure the O-ring is on the air relief valve and is
finger tight prior to starting the pump. This O-ring should
periodically be lubricated with a silicone lubricant.
•There is a 3/8” clear line coming from the filter area, and this
goes to the bottom corner of the spa. This drains all the water
from around the filter canister.
•This is a good time to check the skimmer basket. Bring
skimmer door (weir) forward and unscrew basket. Clean out
debris and reinstall.
WATER QUALITY MAINTENANCE
Maintaining the quality of the water within the specified limits will
serve to enhance your enjoyment and prolong the life of the Patio
Spa’s equipment. It is a simple task, but it requires regular attention
because the water chemistry involved is a balance of several
factors. There is no simple formula, and there is no avoiding it. An
indifferent approach to water maintenance will result in poor and
potentially harmful conditions for soaking and even damage to your
Patio Spa investment. The most important thing to keep in mind is
that preventing poor water chemistry is much easier than correcting
poor water chemistry. For specific guidance on maintaining water
quality, consult your Authorized Dealer who can recommend
appropriate chemical products for sanitizing and maintaining your
Patio Spa.
MAINTAIN HEALTHY SPA WATER
Important! When maintaining your Swim Spa’s water chemistry,
ensure that your cover is removed during any aggressive
treatments to allow for dissipation into the air. Take care to remove
the cover slowly and chemicals deplete if you are uncertain if your
water is properly balanced. Always maintain your swim spa’s water
chemistry within the following parameters:
pH: pH is a measure of relative acidity or alkalinity of water and is
measured on a scale of 0 to 14. The midpoint of 7 is said to be
neutral, above which is alkaline and below which is acidic. In Swim
Spa water, it is very important to maintain a slightly alkaline
condition of 7.2 to 7.8. Problems become proportionately severe the
further outside of this range the water gets. A low pH will be
corrosive to metals in the Swim Spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling), cloudy
water, and a prematurely dirty filter. In addition, the ability of the
sanitation agents to keep the Swim Spa clean is severely affected
as the pH moves beyond the ideal range. That is why almost all
Swim Spa water test kits contain a measure for pH as well as
sanitizer. DO NOT use strong acids like Hydrochloric acid or
Muriatic acid to balance the pH as it could severely damage the
spa shell.

Sanitizer (Chlorine or Bromine): To destroy bacteria and organic
compounds in the Swim Spa water by breaking them down into non-
harmful levels which get filtered out. A sanitizer must be used
regularly, either chlorine or bromine. Sanitizing your spa water is the
most important spa maintenance you can do for yourself.
Total Alkalinity (TA) is the measure of the dissolved alkaline agents
such as carbonates and bicarbonates. These alkaline agents help
prevent rapid changes in pH by acting as a pH buffer. Controlling
alkalinity can help keep your pH in the appropriate range thereby
lessening the need for pH balancing. If the TA is too low the pH level
will fluctuate rapidly from high to low. If the TA is too high the pH will
tend to be too high and will be very difficult to bring back down.
Calcium Hardness: This is a measurement of dissolved calcium in
the water. Calcium will help control the corrosive nature of the spa’s
water. Low calcium hardness causes spa and equipment corrosion
whereas high calcium hardness results in cloudy water and scale
build-up on the spa and the equipment.
Look for these specialized cleaning attachments at your
local dealership.
WARNING: Never store chemicals inside the equipment area of
your swim spa.
IMPORTANT: Do not use Hydrogen Peroxide based sanitizers in
your swim spa. When using Chlorine or Bromine tablets you must
use a floating dispenser. These chemicals can have an extremely
corrosive effect on certain materials in the swim spa. Damage
caused by use of these chemicals, or improper use of any
chemicals, is not covered under the spa limited warranty.
OTHER ADDITIVES: Many other additives are available for
your swim spa. Some are necessary to compensate for out-
of-balance water, some aid in cosmetic water treatment and
others simply alter the feel or smell of the water. Your
Authorized Dealer can advise you on the use of these
additives.
DIVERTER MAINTENANCE
CAUTION: Turn off the spa from main GFCI breaker
before carrying out any maintenance procedures.
