When installing and using this electrical equipment, basic safety precautions should always be
followed, including the following:
READ AND FOLLOW ALL INSTRUCTIONS
1. WARNING: To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
2. WARNING: A wire connector is provided on this unit to connect a minimum 4.11 mm (No. 6 AWG) solid
copper conductor between this unit and any metal equipment, metal enclosures of electrical equipment, metal
water pipe, or conduit within 1.5m (5 feet) of the unit.
3. DANGER RISK OF INJURY: (For cord and plug connected units):
a. Replace damaged cord immediately
b. Do not bury cord
c. Connect to a grounded, grounding type receptacle only.
4. WARNING: (For units with a Ground Fault Circuit Interrupter (G.F.C.I.): This product is provided with a
Ground Fault Circuit Interrupter “G.F.C.I.” on the end of the spa’s power cord. This G.F.C.I. must be tested
before each use. With the product operating depress the “test” button on the G.F.C.I. The spa should not
operate. Depress the “Reset” button on the G.F.C.I. The product should now operate normally. If the spa fails
to operate in this manner, there is a ground current flowing indicating a possible electric shock. Disconnect the
power until the fault has been identified and corrected by a certified licensed electrician.
5. WARNING: (For permanently installed units):
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 442-20 of the National Electric Code. ANSI / NFPA 70-
1987. In addition, all 230 volt installations must be protected by a 230 volt Ground Fault Circuit Interrupter
"G.F.C.I.". Any G.F.C.I. circuit breaker used in the house panel must read current returning through the neutral
conductor. 230 volt 2 conductor G.F.C.I. circuit breakers will not operate correctly for your application.
6. 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. For additional protection, select a cover which is classified by the Underwriters Laboratories Meeting
ASTM F1346-91 requirements.
7. 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 suction fittings are broken or missing. Never replace a suction fitting with one less than
the flow rate marked on the original suction fitting.
8. DANGER RISK OF ELECTRIC SHOCK: Install at least 1.5m (5 feet) from all metal surfaces. As an
alternative, a spa may be installed within 1.5m (5 feet) of metal surfaces if each metal surface is permanently
connected by a minimum No. 4.11 mm (No. 6 AWG) solid copper conductor to the wire connector on the
terminal box that is provided for this purpose.
9. DANGER RISK OF ELECTRIC SHOCK: Do not permit any electric appliance, such as light, telephone, radio,
or television, within 1.5m (5 feet) of a spa.
10. WARNING TO REDUCE THE RISK OF INJURY:
a. The water in a spa should never exceed 40°C (104°F). Water temperatures between 38°C (100°F)
and 40°C (104°F) are considered safe for a healthy adult. Lower water temperatures are
recommended for your children and when spa use exceeds 10 minutes.
b. Since excessive water temperatures have high potential for fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 38°C
(100°F).
c. Before entering spa, the user should measure the water temperature with an accurate thermometer
since the tolerances of water temperature-regulating devices vary.
(Safety instructions continued on next page)

5
d. The use of alcohol, drugs, or medication before or during spa use may lead to unconsciousness with
the possibility of drowning.
e. 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 a spa.
f. Persons using medication should consult a physician before using a spa since some medication may
induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
11. WARNING:
a. People with infectious diseases should not use a spa or hot tub.
b. To avoid injury, exercise care when entering or exiting a spa or hot tub.
c. Do not use a spa or hot tub immediately following strenuous exercise.
d. Prolonged immersion in a spa or hot tub may be injurious to your health.
12. Caution: Maintain water chemistry in accordance to manufacturer’s instructions.

Your spa can be a source of great pleasure. It offers healthful stimulating recreation and is a delightful fun center for
you, your family and friends. However, it contains large quantities of water and is deep enough to present inherent
dangers to life and health unless the following safety rules are strictly observed.
13. Never permit the spa to be used unless it is attended by at least one person other than the bather.
Someone should be present to lend assistance if the bather should be in trouble due to injuries, cramps,
drowning especially in case of children, etc.
14. Always use care in and around your spa.
The spa has many rigid, unyielding parts and many areas that become wet and slippery; these are all
potentially dangerous when rough play is permitted or if care is not used particularly when entering or leaving
the spa.
(Safety instructions continued on next page)
15. Keep the water sanitary and healthful at all times.
Your filter system will remove suspended particles from the water. Regular application of spa chemicals in
proper quantities will destroy harmful bacteria and prevent formation of algae. Your surface skimmer will
remove insects, leaves, and other debris from the water surface. Unsanitary water is a serious health hazard.
16. The water in your spa should NOT be warmer than 38°-40°C (100° - 104° F).
Always keep an accurate thermometer in the water because your spa’s thermostat may be in error. Use a high
quality, shatterproof thermometer with increments of one degree or less.
The National Spa and Pool Institute consider a temperature of 38°C (100°F) safe and comfortable for a
healthy adult. Most healthy adults can enjoy this water temperature for as long as desired, although it may
raise the body temperature to the water temperature and eventually become uncomfortable (like a fever). At
higher water temperatures the soaking time should be shorter; never soak for more than 20 minutes when the
water temperature is 39°C (102°F) or higher. If you are planning a long rest in the spa, lower the water
temperature closer to normal body temperature, about 37.2°C (99°F). Some people find even lower water
temperatures relaxing and pleasing. Try different water temperatures in the 36.6°-39°C (98°-102°F) range until
you find what temperatures suit you best.
17. Hot water can raise the body temperature high enough to cause heat stroke.
This can be fatal even to healthy adults. If you have any questions about your own fitness or whether you
should soak in the spa, check with your physician.
18. Prolonged immersion in hot water may induce hyperthermia.
Hyperthermia occurs when internal body temperature reaches a level several degrees above the normal body
temperature of 36.6°C (98.6°F). The symptoms of hyperthermia include: (1) dizziness, (2) fainting, (3)
drowsiness, (4) lethargy, (5) increases in the internal body temperature. The effects of hyperthermia include:
(1) unawareness of impending hazard, (2) failure to perceive heat, (3) failure to recognize the need to exit spa,
(4) physical inability to exit spa, (5) unconsciousness resulting in danger of drowning.

6
19. WARNING: The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia
in hot tubs or spas.
Despite the popular image of people in spas drinking wine or other alcoholic beverages, DO NOT use
alcoholic beverages before or during spa use. Alcohol is a depressant which causes slowed reflexes and
drowsiness, especially in conjunction with the relaxed soaking in hot water. This can lead to sleep or
unconsciousness and possibly result in drowning. Using your spa with other people who are also drinking is
not a preventative measure since they are likely to become similarly affected by the combinations of alcohol
and hot water soaking.
Soaking in hot water causes changes in the circulatory system, such as enlargement of blood vessels near the
skin. Therefore, people with a medical history of heart disease, circulatory problems, diabetes, high or low
blood pressure should check with their physician before using spas. Additionally, people taking medications
causing drowsiness, such as tranquilizers, narcotics, antihistamines, or anticoagulants should not use spas
without asking their physician.
20. Broken or missing drain covers should be replaced immediately.
Accidents can occur when long hair or a body part is trapped by suction from a drain or outlet whose cover is
broken or removed. Children are particularly vulnerable, and they should be warned against danger.
21. WARNING: Do not use electrical appliances in or around your spa. Do not use glass or other breakable items
in or around your spa. Do not remove spa cabinet panels and attempt to make repairs. Do not attempt
electrical repairs. Retain a certified licensed electrician.
22. This spa is for residential use only. It is not intended for commercial use.

Site Selection
Your new spa will provide you and yours with hour upon hour of healthy, relaxing enjoyment. The following suggestions
and recommendations will help you select a safe and compatible site for your spa, maximizing your enjoyment.
Before proceeding, please read the “Important Safety Instruction” at the beginning of this manual.
1. Certified Licensed Electrician Required. Electrical installation, (approval of and connection to power source)
must be completed by a qualified certified licensed electrician in compliance with all codes.
2. No Overhead Power Lines. Do not locate your spa under overhead power lines or in near proximity to existing
buried or exposed electrical circuits. See your electrician.
3. Childproof Your Spa. Plan for limiting access of children. Precautions such as self closing and locking gates or
access doors, fencing and other child barriers, as dictated by the site.
4. UL Safety Cover Required. In addition to its insulating factors, a good cover also provides a measure of
additional protection from unwanted access. Select a cover which is classified by the Underwriters Laboratories
meeting ASTM F1346-91 requirements.
CAUTION: Your spa must be installed on a level, flat, solid load-bearing surface. Do not locate the spa on a surface that
can be damaged or altered by water.
Provide a solid load-bearing site:
The site must provide a solid foundation with a minimum load bearing capacity of 34 kg per 929 sq. cm (75 pounds per
square foot). Concrete slabs and decks must be designed to support this weight. Do not select a site composed of
individual unsupported bricks, blocks, or other materials which will shift unevenly and cause damage to your spas internal
frame.
Provide a level, flat site:
A level site is critical to both the performance and enjoyment of your spa. Water
is unforgiving and will always settle level. A flat and level site provides the surface necessary to properly dispense weight
between the foot well (which bears most of the spa’s weight) and the structural frame which primarily provides stabilization
and secondary support. The importance of proper support for the foot well in conjunction with the spa cabinet can not be
over stressed.
F
Fi il ll li in ng g Y Yo ou ur r S Sp pa a
Make sure that the electrical cord has been routed properly. (See page 8). Do not supply electrical power at this
point.
Check to be sure that the drain valve is closed and that the drain safety cap is securely in place. (See page 8)
Remove filter cartridge and place garden hose end through opening (inside filter area), fill the spa with cold (never warm or
hot) water 150 to 200 mm (6” to 8”) below the top edge of the spa. Do not overfill, as the spa’s water level will rise as each
person enters the spa.
Always keep the spa water level above the jet openings.

The spa equipment requires a 15 amp outlet, dedicated to the spa. The use of any extension cord will void your warranty.
Carefully read all of the safety requirements before plugging in the spa.
Figure 1 Figure 2 Figure 3
The spa drain valve assembly consists of a garden hose connector with a twist on/off valve and a safety drain
cap. It is located outside at the bottom of the spa.
EACH TIME BEFORE FILLING THE SPA
1. Make sure the drain valve is closed. Turn handle clockwise until it stops.
2. Make sure the safety cap is secure. Turn handle clockwise until it stops.
3. If the drain valve is facing a wall, leave enough space between the drain valve and wall 15.4 cm (6"
minimum) to allow enough room to connect a garden hose.
TO DRAIN THE SPA
Drain every three months. Draining your spa on a regular basis rids the spa of dissolved solids and protects your
spa equipment from the effects of residual calcium hardness and total alkalinity problems
1. Turn Power Off. Turn power off at the spa consoles and deactivate any disconnect switches at the
G.F.C.I. plug or load center.
2. Locate Spa Drain Valve. The drain valve is located outside, at the bottom of the spa. See figures 1, 2 and
3 for reference.
3. Remove Drain Valve Safety Cap. Remove the safety drain cap (see figure 1) and store for use when
refilling your spa. Attach a standard garden hose to the drain valve.

4. Select Safe Suitable Drain. Route the hose to a sewer drain capable of safely assimilating 300 plus
gallons of water which may contain both unsanitary contaminants and chemical residue. To open the
drain valve twist counter clockwise, then pull outward (see figure 2).

Spa heating modes
The Heating Mode offers the ability to control your heater in special circumstances. Your spa is preset at the factory to
Standard Mode. However, the Standard Heating Mode can be changed to Economy or Sleep by pressing the or
then button. With each press of the buttons, the display will cycle through the three different modes described
below.
Standard Mode (ST): Your spa is preset to this mode. This mode operates the heater whenever needed to maintain the
programmed spa water temperature. (See Temperature Adjustment page 10).
Economy Mode (EC): This mode operates the heater only during programmed Filtering Cycles (See Spa Water
Maintenance page 10). This mode is ideal for areas that charge a premium for electricity during peak hours. This mode will
maintain the thermostat setting. If it does not reach the thermostat setting, you may have to allow for more heating time by
increasing the Filtration Cycles.
Sleep Mode (SL): This mode works in the same manner as the Economy Mode except the thermostat setting is
automatically lowered by 20 degrees. This mode is best suited for extended leaves from home when it is not important to
maintain constant water temperature, such as vacations or business trips.
Summer Set Temperature
In hot weather, it is possible for water temperature to exceed the temperature setting. This is especially common when
your temperature setting is lower than air temperature. If the water temperature exceeds the temperature setting more
than 3°, an automatic safety circuit will turn off all of the electrical systems. The systems will remain off until either the
water temperature cools to below the setting, or the setting is increased above the water temperature.

The spa is equipped with massage jets, two anti-vortex
main drains and an automatic skim filter.
Adjusting Massage Jets
The massage jets may be adjusted for both volume
and direction.
To adjust the jet for direction simply rotate the jet’s
eyeball fitting in the direction desired. To adjust the
jet’s flow rate, rotate the jet’s outer faceplate about 1/4
turn counter-clockwise to increase the flow or
clockwise to decrease the flow. (DO NOT FORCE)
Suction Fittings
Keeping the suction fitting covers clean and clear of all
obstructions is critical in order to have a safe operation
of the spa. See the safety instructions on page 4 for
additional for details.
Surface Skim Filter
The spa’s automatic surface skim filter is designed to
remove floating debris and contaminants such as body
lotions by drawing water through a specially
formulated filter cartridge element. It is critical that this
element be routinely cleaned.
To Clean the Cartridge:
1 Place system on Lockout Mode or disconnect
power.
2 Remove the filter cover.
3 Turn cartridge counterclockwise and pull up.
4 Remove the cartridge element and thoroughly
rinse with a garden hose until element is free from dirt
and debris.
5 Return the cartridge to the filter well by
following steps 1 - 4 in reverse order.
Air Injection Venturi Adjustment
Air injection into the massage jet water flow may be
controlled by manipulation of the venturi dials located
on either side of the spa. Each dial is independent and
controls up to 5 jets respectively.

Spa water chemistry (or water balance) affects the safety of your equipment as well as the
appearance of your spa water. Water balance has five factors: pH, total alkalinity, calcium
hardness, temperature and total dissolved solids. pH is the most critical but total alkalinity and
calcium hardness must also be watched closely. Low calcium hardness can lead to corrosion of
equipment, while high calcium hardness can lead to scaling, cloudy water and staining. Water
temperature should never exceed 40°C (104°F), and total dissolved solids should be kept below
1500 PPM.
Algicidal and sanitizing chemicals are either alkaline or acid. Sodium and calcium hyprochlorites
are alkaline. Chlorine gas and practically all other dry chlorine spa products are acid. On the
market are a number of bromine sanitizers. Bromines are usually preferred since they don’t emit a
strong chlorine odor.
SEE YOUR SPA WATER EXPERT FOR ADDITIONAL INFORMATION
USE OF CALCIUM HYPOCHLORITES OR TRICHLORS WILL VOID WARRANTY
1. Check and adjust water conditions. You must maintain proper chemical balance to insure safe
sanitary conditions and to prevent your spa from becoming a breeding place for bacteria. This is
done by:
A. Test daily and maintain pH between 7.2 and 7.8. Adjust if necessary, above 7.8 use pH
decrease, if below 7.2 use pH Increase. Improper pH can damage spa finish, equipment,
cause eye irritation and chemical loss. Use dosage according to manufacturer’s label.
B. Test alkalinity and maintain at 80 ppm to 140 ppm. Adjust if necessary, above 140 ppm use
pH Decrease, if below 80 ppm use Total Alkalinity Control. Use dosage according to
manufacturer’s label.
C. Test daily and maintain proper sanitizer level. It’s recommended to use bromine sanitizer
and maintain bromine at 3.0
5.0 ppm. Typically two or three bathers relaxing in an average spa with 103°F (39.4°C)
temperature will consume all the bromine sanitizer in about twenty minutes. Therefore,
prolonged or heavy use may require additional bromine to maintain safe sanitary conditions.
D. “Shock” (with a non-chlorine shock) once a week and after each water change. Do not use
spa until the bromine residual has dropped to less than 5.0 ppm. NOTE: Improper pH will
cause early corrosion to your pump. Corrosion is not handled under any warranty.
SPA MAINTENANCE SCHEDULE
