•Danger. A grounding wire connector is provided on this Aquatic Fitness System to connect a
minimum No. 8 AWG (8.4 mm2) solid copper conductor between this unit and any metal
equipment, metal enclosures of electrical equipment, metal water pipe, or conduit within 5 feet
(1.5 m) of the Aquatic Fitness System.
•Risk of Electric Shock. Do not attempt to remove the light housing cover without lowering the
water level below the light housing cover.
•To Reduce the Risk of Injury: The water in the Aquatic Fitness System 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 Aquatic Fitness System use exceeds 10 minutes.
•To Reduce the Risk of Injury: 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 Aquatic Fitness System water temperatures to 100° F (38° C).
•To Reduce the Risk of Injury: Before entering the Aquatic Fitness System, 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).
•To Reduce the Risk of Injury: The use of alcohol, drugs, or medication before or during Aquatic
Fitness System use may lead to unconsciousness with the possibility of drowning.
•To Reduce the Risk of Injury: Pregnant women, the elderly, infants, or persons suffering from
obesity or with a medical history of heart disease, low or high blood pressure, circulatory system
problems, or diabetes, should consult a physician before using the Aquatic Fitness System.
People with infectious diseases should not use an Aquatic Fitness System.
•To Reduce the Risk of Injury: Persons using medication should consult a physician before
using the Aquatic Fitness System since some medication may induce drowsiness, while other
medication may affect heart rate, blood pressure, and circulation.
•Observe a reasonable time limit when using the Aquatic Fitness System. Long exposures at high
temperatures can cause high body temperature (hyperthermia, see pg. 3). Enter and exit the
Aquatic Fitness System slowly. Wet surfaces can be very slippery.
•Proper chemical maintenance of Aquatic Fitness System water is necessary to maintain safe
water and prevent possible damage to Aquatic Fitness System components.
•Use the cover straps and clip tie downs to secure the cover when not in use. This will help
discourage unsupervised children from entering the spa and keep the spa cover secure in high
wind conditions. There is no guarantee that the cover, clip tie downs, or the actual locks will
prevent access to the Aquatic Fitness System.

Initial Startup
Go over the initial startup with your dealer before they begin the installation of your spa.
IMPORTANT: About your GFCI Circuit Breaker — The GFCI (Ground Fault Circuit Interrupter —
also called a "circuit breaker”) automatically shuts off power to the Aquatic Fitness System in case of
an electrical malfunction. You must have a GFCI installed according to your local building codes in
an electrical power box near your system. The GFCI must be OFF before you fill your Aquatic Fitness
System with water. You can manually turn off power to the system any time by moving the switch into
the OFF position. After turning off the GFCI check for a blank control panel screen which means the
power is off. To turn power back on move the switch to the ON position.
If you have questions about the location or operation of your GFCI, ask your dealer for clarification.
DO NOT use your system unless you understand the operation of the GFCI.
1. Locate the equipment
compartment, beneath the steps
of the AFS. Have your dealer
familiarize you with the equipment
components.
2. Use a Phillips screwdriver to
remove the equipment
compartment screws. Open the
compartment.
3. Check the pump unions (see
photo) for hand-tightness and to
prevent the possibility of
leakages.
4. Check near the pumps to make sure
the gate valve has the red safety clips
in place which means that the gate
valve is open (see photo above).
5. Remove the two front and two rear
shipping bolts on each pump mount.
(See photo, left).

6. Remove the
filter baskets
and the foam
blocks securing
the filters.
7. Remove one of
the two filters
from the pool side of the system. (If
you have the Dual-Temp model with
separate built-in spa, also remove the
filter from the spa side). (If you need
more details on how to remove the
filters, see the Filter Cleaning section,
pg. 23)
8. Ensure that the hose
bibs are closed before
filling the spa. The
hose bibs are
connected to hoses in the equipment
compartment. Turn the handles on
the side of the valve perpendicular to
the pipe to close the hose bibs. The
picture at right shows an open hose
bib.
9. Place a garden hose in
the empty filter canister
to fill the system. Fill
the system until the
water level reaches the
center of the tile line.
10. After filling the system, return the filter to its basket. After the filter is in place, turn on the
GFCI circuit breaker. The Display Window of the Pool will show the current water
temperature.
NEVER run your spa’s pumps without the filters in place. This can cause damage to
the pumps.
11. Prime the pumps by pushing the JETS 1 button once and letting it
run for 30 to 45 seconds. To turn off, push it again. Repeat for the
JETS 2 and JETS 3 buttons.
If the jets do not turn on, air is trapped in the plumbing lines. To
eliminate the trapped air, turn the pumps on and off several times to
force the trapped air through the pumps. If the jets still do not turn on,
turn off the pumps and loosen the pump unions slightly to let any
trapped air escape. Re-tighten the pump unions and turn the pumps on
again. Turn the pumps on and off several times until jets function
properly.

12. Press the Warmer (UP) Button and Cooler (DOWN) Buttons until
your desired water temperature appears. The Display Window
shows your Set Temperature for five seconds before reverting back
to the current water temperature.
If you have the Dual-Temp model with built-in spa, likewise set the spa
temperature using the + and – buttons. See the spa programming
section later in this manual for more details. (pg. 15)
The Display Window does not allow you to set the temperature above 104°F
(≅40°C). However, if the water temperature exceeds 104°F (≅40°C), the display will
show the actual temperature. Never get in water if the temperature exceeds 104°
F (≅40°C).
13. While heating the spa, inspect the pump unions and plumbing fittings for leaks. When you
have finished the inspection, you can reinstall the equipment compartment panel.
14. After completing the above steps, see the Water Care Guide (provided separately) to
ensure proper water chemistry.
15. Place the thermal cover on your Aquatic Fitness System to conserve energy and keep it
ready for use.

Using Your Aquatic Fitness System
Using the “Pool-Side” Control Panel
Your Aquatic Fitness System has a Control Panel on the top side to control the Pool Functions. (If
you have the “Dual Temp” model the spa-side functions are controlled by a separate panel, pg. 12).
The Display Window
The Display Window shows the current water temperature, except when you
adjust the temperature. Five seconds after you finish setting the desired
temperature, the Display Window reverts back to the current temperature.
Jets 1 Button
Pressing the Jets 1 button once turns Pump 1 on low speed. A second press
turns it to High Speed. A third press turns the pump off, unless the pump has
been automatically activated during a heating cycle – in which case a third
press returns the pump to Low Speed for heating. A built-in timer automatically
shuts the pump off after 20 minutes of operation. The Jets 1 Indicator light
(beside the button) will glow while the pump is running.
Pump 1 powers the Swim Jets and/or HydroTherapy Jets.The diverter valve
(see left) controls which set of jets gets the water, and how much flows to
each set. (Note: If you have the Dual Temp model with built-in spa, the spa
side has a diverter valve but the swim side does not.)
Pump 1 also runs on low speed during all filtering and heating cycles. During the
filter cycle the indicator light for Jets 1 glows. If you manually press JETS 1 during a
filter cycle, that particular filter cycle disables to give you control of the jet pump.

Dimension One Spas - Aquatic Fitness System - Owner’s Manual
9
Jets 2 and Jets 3 Buttons
Pumps 2 and 3 provide high-volume water flow to the Swim Jets.
Press the appropriate button once to turn on Pump 2 or 3. The pumps work
independently, giving you flexible control over the amount of water flowing
from the Swim Jets. Pressing either button a second time turns that pump off.
A built-in timer will shut the pump(s) off after 20 minutes of operation unless
you manually shut them off earlier. The Jets 2 or Jets 3 Indicator light beside
the button will glow when that pump is running.
If your system was installed with less than the maximum recommended electrical
service for heat and pumps, the heater will turn off when the pumps run at high
speed. If you have the maximum electrical service, then you can continue to heat
your water while running the pumps at high speed. Ask your dealer if you have
questions about your electrical service.
Light Button
Push the LIGHT Button once to turn on the spa light in Color Change mode.
In Color Change mode, the light will continuously cycle through Red, Green,
Blue, White and Magenta. To switch to Color Select mode, which holds the
current color, turn the light off by pushing the LIGHT Button, then push the
LIGHT Button again to turn the light back on in Color Select mode.
Alternately, you can hold the LIGHT Button until you see the light flash off
and on to turn on the light and start in Color Select mode.
If you have more than one light in your spa and the lights are no longer
synchronized, power off the lights for 3 to 9 seconds. When powered on, all
lights will be resynchronized and reset to Color Change mode.

Use the WARMER and COOLER buttons
to scroll up or down through the filtering
modes. The filter cycles look as follows:
•Standard Mode: F1,F2,F3
•Economy Mode: F4, F5,F6
•Lockout Mode: L1,L2
Selecting a Filter Cycle
Standard and Economy Mode
In the standard modes your system heats whenever the water temperature drops to 2°F (≅1°C) below
your set temperature, and continues heating until the water is 2°F (≅1°C) above your set temperature.
In Standard Mode, heating the water remains independent of the filter cycles.
In economy mode, the water only heats when the filter runs during a normal filtration cycle.
After entering the filter programming mode press the WARMER (up) button or the COOLER (down)
button until you see F1, F2, F3, F4, F5 or F6.
F1: 2 hours of filtration 2 times a day. (Standard)
F2: 2 hours of filtration 3 times a day. (Standard)
F3: 2 hours of filtration 4 times a day. (Standard)
F4: 2 hours of filtration and heat 2 times a day. (Economy)
F5: 2 hours of filtration and heat 3 times a day. (Economy)
F6: 2 hours of filtration and heat 4 times a day. (Economy)
If you make no further changes for three (3) seconds, the system automatically stores your choice
and exits the programming sequence.
If the display window displays COL or ICE, cool or ice conditions have
been detected. These conditions override economy mode. The system
heats as needed to prevent freezing damage, regardless of the filter
cycle. For more information, see the Troubleshooting Guide (pg. 26).

HydroSport™Swim System
Important Safety Instructions
Never let children play with the Swim Tether Cord. They could get the cord wrapped
around their neck and suffocate.
Swimming in your Aquatic Fitness System (AFS) requires that you follow swimming safety
precautions. Your AFS offers a variety of exercises that require awareness of many safety and health
precautions.
Using the Swim Tether
The HydroSport™Swim Tether system that comes with the AFS provides
multiple stationary exercises.
The Swim Tether system includes a 7-foot
Swim Tether Pole, an adjustable Swim
Tether Belt, and 7 feet of Swim Cord.
The belt snaps easily around your waist
using a quick-release buckle and adjusts
from the back.
Swim Tether Mounts are located at either end of the AFS (see picture at
left). Place the pole in the mount, strap on the adjustable belt and adjust
the cord length.
If speed is your goal, the Swim Tether allows you to swim as fast as you want and
remain stationary.
Do not allow your Tensor Cords to remain in direct sunlight for extended periods of
time. Exposure to direct sunlight for extended periods of time can cause the Tensor
Cords to deteriorate. Deteriorated, or damaged, Tensor Cords could break and
cause injury if the break should occur during use.
Be sure to examine your Tensor Cords for damage or deterioration prior to each use.
Do not use damaged or deteriorated Tensor Cords.
Do NOT adjust any piece of HydroSport equipment too tightly! If a piece is too tight it
might not release in the event of an emergency.

Using the Swim Kick Bar
A swim kick bar at the end opposite the steps comes standard on
all the AFS models.
Use this bar as you would the edge of a pool to do kicking or
standing exercises.
Using the Swim Jets
The swim jets in your Aquatic Fitness System are adjustable, allowing you to get the most out of your
exercise.
When swimming, use the tile markers on the side, front and bottom of the spa to properly position
yourself in the swim lane. You can also use the swim jets for resistance to while walking or jogging in
place.
Using the Diverter Valve
The diverter valve at the filter end of the AFS controls water movement from Pump 1. Turn the valve
to direct water flow either in the direction of the hydrotherapy or swim jets.
Adjusting Air Flow
The air valves located at the front of the AFS
control the amount of air added to the water. The
window in the air valve informs you of the amount
of air being mixed with the water at the swim jets.
