• • • accessible for maintenance. Use a bathing cap for long hair. Refer to information on hyperthermia, next page. Use only authorized spa care products for the best performance and to keep the water properly balanced. Don’t: • Use the spa at 104°F (40°C) for long periods of time (more than 30 minutes). See Hyperthermia, below. • Use an extension cord to power your spa. • Allow anyone to stand on the spa cover. It is not designed to support weight.
SPA INSTALLATION Danger: Electrical shock risk. Install at least 1.5m from all metal surfaces. 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/NFPA702008. The disconnecting means must be readily accessible but installed at least 6 feet (1.8 meters) from the spa water. All electrical connections should comply with article 680-IV of the NEC.
7. Indoor sun rooms are capable of maintaining high ambient temperatures which may effect the spa water temperature. It is NOT recommended that you operate your filter cycles for longer than 4 hours per day under these conditions.

Heater Assembly: Thermostatically controlled and equipped with an overheat safety shut-off. Note: No consumer serviceable parts.
JETS, AIR CONTROLS & VALVES Jets All spa jets are individually engineered to provide a unique hydro-massage. Depending on the model, your spa will have a combination of the following jets: Directional Therapeutic (200, 300, and 400 Series Wave Style): Positioned to focus on large muscle groups, these jets deliver a concentrated, high volume stream of water for a deep massage. Each jet is fully adjustable, allowing users to set the water flow to the most comfortable setting.
To clean the jet insert and housing, use a pressurized hose and spray the inside of the jet housing. Soak the jet in a diluted spa cleaning solution, rinse. Wipe the inside of the housing to remove any debris. To reinstall the jet, line up the tab on the backside of the barrel with the groove in the body. Use the palm of your hand to gently tap the jet until it snaps into position.
ELECTRICAL INFORMATION Caution: Risk of electrical shock. Read and follow all instructions. Important Safety Instructions All electrical connections to this spa package MUST be accomplished by a qualified licensed electrician in accordance with National Electrical Code (NEC) and with state/ local electrical codes in effect at the time of installation. NOTE: Prior to performing any service to the spa equipment, turn OFF all primary electrical power at the main circuit breaker or disconnect panel.
ELECTRICAL INFORMATION Caution: Risk of electrical shock. Read and follow all instructions. REQUIREMENTS The spa must be connected to a dedicated 120 volt, 15 amp, grounded circuit. The term “dedicated” means the electrical circuit is not being used or shared for any other electrical items (patio lights, appliances, garage circuits, etc.). If the spa is connected to a non-dedicated circuit, overloading may result in “nuisance tripping” at the main panel.
START UP PROCEDURES Follow recommendations for site location and electrical connection. The water line on the weir door is the level at which the water should be maintained. 1. Fill the spa through the filter hole to 1/8” below the top of the Weir door. with tap water. Never use ‘softened’ water in your spa. Softened water can impact the chemical balance of the water and lead to degradation of metal plumbing fittings. 2. Turn power on to unit at circuit breaker or disconnect panel. 3.
POWERWORKS ® 300 CONTROL Duet Your Topside Control looks like this, your spa has the following features: • Internal Light • 1 Dual Speed Pump The 300 Series Powerworks™ Controls offer you the ultimate in spa control. The backlit, Liquid Crystal Display (LCD) displays current temperature, set water temperature, and operating mode settings. Each feature is actuated through the control panel pad. Touch the appropriate button to activate the desired function.
Temperature The maximum set temperature is 104°F (40°C) and the minimum set temperature is 80°F (26°C). The current water temperature or, if the pump has not been running, two dashes, will show on the display. If dashes are displayed, you must first start the pump by pressing the PUMP 1 pad. Wait until the water temperature is displayed (approximately 1 minute). The set temperature of your spa may easily be increased or decreased at any time using the ‘TEMP’ pad.
temperature drops below 45°F (7.2°C). The selected mode will be displayed in the LCD window of the control panel. When in Standard mode, the letters ‘ST’ are displayed beiefly, followed by the water temperature. When in Economy mode, the letters ‘EC’ are displayed alternately with the water temperature. When in Sleep mode, the letters ‘SL’ are displayed alternately with the water temperature.
Any adjustments to set temperature or filter cycle duration may need to be reprogrammed. THERMAL CREEP: see page 24 OZONE OPTION: see page 20 Light Touch the ‘LIGHT’ pad to turn all lights on and off. The lights will automatically turn off after 4 hours of operation. Automatic Time Outs Your Vita Spa is equipped with an automatic Time Out feature designed to protect both the equipment and the user.
MAINTENANCE Water Chemistry Water chemistry is critical in a spa system. Chemicals are used to sanitize the water and control the pH balance. The combination of high water temperature and small water volume means that the chemical balance must be watched carefully. It is recommended that you purchase a chemical start up kit, and the additional chemicals needed to maintain the proper/optimum chemical balance, from your dealer.
Sanitizing with Ozone Spas vary in size, as well as frequency and conditions of use. For this reason you will need to establish your sanitizing program based upon your own personal use. When using ozone, you should start by balancing your water chemistry as you normally would. The Duet model spa should run and be ozonated a minimum of 4 hours per day. If your spa is heavily used, this time should be increased. Your spa produces ozone during the filtration and heating cycles.
garden hose and replace the cap. Repeat for each internal drain hose. NOTE: Do NOT attempt to use the pump to drain the spa. NOTE: Close all drain valves and replace caps prior to refilling the spa. NOTE: When refilling the spa, you may need to bleed air from the system. Refer to Priming Your Spa, pg. 14 for instructions. Filter Maintenance NOTE: It is not necessary to drain the spa in order to clean the filter. The removable filter cartridges are located in the filter canister behind the weir door.
complicated procedure. When at all possible this should be done by a spa service center. A freeze damaged spa can be expensive to fix. With that in mind here are some basic winterizing tips that will help you remove enough of the water and add enough RV Antifreeze to keep your plumbing from freezing. What you will need; 1. A wet /dry (shop vac) vacuum. 2. 1 to 3 gallons or RV antifreeze (nontoxic, used in Recreational Vehicles water tanks) 3. Channel lock pliers (16” works best for most tubs) 4. A funnel 5.
Spa Cabinet Care: The cabinets are made of Excel-X™, a high quality alternative to wood that is virtually maintenance free, requiring no staining, sealing, or waxing. To clean the spa cabinet, rinse dirt and dust regularly with clear water. To remove stubborn dirt, grime, and mild discoloration, wash with a mild detergent and warm water. Protect spa finish - always keep cover on the spa when not in use. Spa Surface Care and Cleaning Your spa shell surface is made of acrylic.
encasement in the sun and foam cores in the shade to dry. (Do not put foam cores in the sun – they will melt!) Once everything is dry, spray the cores and inside the encasement with a mildew inhibitor like Pine Sol®. Allow all to dry completely, and then reassemble. The key here is to maintain proper water chemistry to avoid mildew. If you are using WD-40 to free the Sure-Locs, try using a Q-tip to keep the WD-40 away from your cabinet. (It can damage the finish.

SAFETY SIGN The safety sign enclosed with your Owner’s Manual should be permanently installed where visible to all users of the spa. This sign is adhesive backed and includes four screws for mounting the sign on rough surfaces. It is very important that you, as a spa owner, review the important safety instructions and warnings before you operate your spa. It is equally important that you instruct all users, even occasional ones, as to the warnings associated with spa use.
