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 Cascade Spa in good condition.
WARNING: Improper chemical usage and maintenance will
quickly lead to severe issues with your spa and can effect
the spa equipment, jets, pumps, and all other components
in contact with the spa water. All Cascade 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 spa. Low voltage
damage could result and this is not covered under warranty.
IMPORTANT: Cascade Spas with 110V means that the
jets and heater 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.
The electrical circuit must be installed by a certified
electrician and approved by a local building or electrical
inspector.
Surface
Transport
Your new 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 spa may have spend days or even weeks in transit before arriving at your
home. Please ensure that before filling or operating your Cascade 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 with a clean cloth or sponge using warm water.
Your new portable 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 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 avoid the spa warranty. Contact your dealer if you have any questions
regarding spa location and placement.

IMPORTANT SAFETY INSTRUCTIONS
READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
DANGER: Risk of Injury. The suction fittings in this Cascade
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 Cascade 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 spa without adult supervision. Keep the 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 Cascade
Spa occupant but installed at least 5 feet (1.5 m) from the Cascade
Spa water.
READ, FOLLOW AND SAVE THESE INSTRUCTIONS
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 in the area of the Cascade Spa to
these terminals with an insulated or bare copper conductor not
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
Cascade Spa shall be bonded to the equipment grounding
buss with copper conductors not smaller than No. 6 AWG.
WARNING: To Reduce the Risk of Injury: The water in a
Cascade 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 Cascade 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 Cascade Spa water temperatures to 100 °F (38 °C).
If pregnant, please consult your physician before using a
Cascade Spa. Before entering the Cascade 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 a
Cascade 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 Cascade Spa;
Physical inability to exit Cascade Spa;
Fetal damage in pregnant women; and
Unconsciousness and danger of drowning.
WARNING: Children should not use Cascade Spas without
adult supervision.
WARNING: Do not use Cascade Spas unless all suction
guards are installed to prevent body and hair entrapment.
WARNING: People with infectious diseases should not use
a Cascade Spa.
WARNING: To avoid injury, exercise care when entering or
exiting the Cascade Spa.
WARNING: Do not use drugs or alcohol before or during
the use of a Cascade Spa to avoid unconsciousness and
possible drowning. The use of alcohol or drugs can greatly
increase the risk of fatal hyperthermia in Cascade Spas.
WARNING: Pregnant or possibly pregnant women should
consult a physician before using a Cascade Spa.

GLOSSARY OF TERMS
AIR CONTROL: Mounted generally on the lip of
the 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 spa.
FILTER AIR RELIEF VALVE: Located on top of
dome filter lid. Used to release air from the filter.
SKIMMER BLEEDER VALVE: Located in the
skimmer area, 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.
TOPSIDE CONTROL: 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.
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.

OWNER’S MANUAL INFINITY COLLECTION 2021

to 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

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 spa owners enjoy
placing their spa in a decorative enclosure or a deck. Keep in
mind that you need to have access to the equipment for
maintenance and the 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.
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.

SPA CARE GUIDE
Your Authorized Dealer carries a wide variety of care and
maintenance products. For more information please contact
your Dealer.
REQUIRED FILTER MAINTENANCE
Your new Cascade Spa is equipped with a filter cartridge. To
ensure maximum water quality at all times, you should replace
the filter cartridge every six months, or earlier as necessary. The
filter cartridge is designed to be thrown away! Attempts to re-use
the filter cartridge may result in the re-release of unwanted
particles back into the Cascade Spa.
PLEATCO DUAL CORE FILTERS
Your Cascade Spa/spa comes with a premium filter. Most come
with 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 similar to 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 Cascade
Spa. Our Cascade Spas come with only the best filters
available in order to ensure your satisfaction.
REQUIRED WATER REPLACEMENT
You should replace the Cascade Spa’s water every 3-6 months.
The frequency will depend on a number of 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
Cascade 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 suggested
conditions.
•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 you 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 degrees Fahrenheit and 116
degrees Fahrenheit or 1 degree Celsius and 47 degrees
Celsius.
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.
CASCADE SPA INTERIOR
Your Cascade 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. 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.

OWNER’S MANUAL INFINITY COLLECTION 2021
13
DO NOT leave your Cascade 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”.
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 Cascade Spa. In
addition, off-gas your spa 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 Cascade Spa’s electrical equipment.
CEDAR CABINET
Our cedar cabinets are made from top quality Western Cedar
and manufactured and stained at our factory. With proper care
and maintenance, your cedar cabinet should maintain its beauty
for many years. Manufacturer recommends touch-up or re-
staining of the cabinet every three to four years depending on
your environment. Contact your Dealer for re-staining
procedures.
VINYL CABINET
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.
SLATE CABINETS
Optional Slate cabinets are custom-built and painted in
our factory. We recommend lightly brushing the cabinet
with a SOFT bristle brush to remove any dirt or stains.
For more information on the care of your Slate cabinet,
please contact your Local Dealer.
COVER CARE
A well cared for spa cover is a thing of beauty in its own right. 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 time 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 remain locked at all times 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.
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/
Cascade Spa and in line of sight from the equipment
compartment.

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
Cascade Spa’s equipment. It is a fairly 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 Cascade 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 Cascade Spa.
MAINTAIN HEALTHY SPA WATER
Important! When maintaining your Cascade 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 let chemicals deplete if you are uncertain if your
water is properly balanced. Always maintain your Cascade 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
Cascade 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 Cascade Spa equipment. A high pH will
cause minerals to deposit on the interior surface (scaling). In
addition, the ability of the sanitation agents to keep the Cascade Spa
clean is severely affected as the pH moves beyond the ideal range.
That is why almost all Cascade Spa water test kits contain a
measure for pH as well as sanitizer.
Sanitizer (Chlorine or Bromine): To destroy bacteria and
organic compounds in the Cascade 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: This refers to the ability of the Cascade Spa
water to resist changes in pH. 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.
WARNING: Never store chemicals inside the equipment
area of your spa.
IMPORTANT: Do not use Hydrogen Peroxide based
sanitizers in your 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 spa. Damage caused by use of these chemicals, or
improper use of any chemicals, is not covered under the
spa’s warranty.
OTHER ADDITIVES: Many other additives are available
for your 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.
Look for these specialized cleaning attachments at your
local dealership.
WATER DIVERTER MAINTENANCE
CAUTION: Turn off the spa from main GFCI breaker to
carry out any maintenance procedures.
Steps to clean water diverters
1. Pull the diverter cap off and rotate the diverter body
counter clock wise and pull out the assembly (Picture
1a to 1c).
2. Using clean piece of cloth, remove the dust particles or
depositions (Picture 2).

3. Assemble the diverter body by inserting the body back by
rotating the jet body clock-wise (Picture 3a and 3b). Attach
the diverter cap.
JET MAINTENANCE
CAUTION: Turn off the spa from main GFCI breaker to carry
out any maintenance procedures.
It is important to regularly clean the jets to prevent any
unwanted depositions and potential damage to the plumbing.
It is the responsibility of the customer to regularly perform the
maintenance procedures. To clean and maintain optimum jet
functions, follow the maintenance instructions below.
LAMINAR FLOW JET MAINTENANCE INSTRUCTIONS
1. Rotate counter clock wise and pull out the jet body (Picture 1a
and 1b).
2. Using clean piece of cloth, remove the dust particles or
depositions (Picture 2).
3. Remove the unreachable debris with the help of vacuum
cleaner (Picture 3).
4. Assemble the jet insert back by rotating the jet body clock-
wise (Picture 4a and 4b).
