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.
