A wire conductor is provided on this unit to connect a minimum 6 AWG (13.
Safety Instructions Important Safety Instructions (cont.) (For units with GFCI) WARNING – This product is provided with a ground-fault circuit interrupter located on the front panel of selected swim spas. The GFCI must be tested before each use. With the product operating, open the service door. When the product stops operating, this merely indicates that the door is equipped with an electrical interlock. Next, push the test button on the GFCI and close the service door. The product should not operate.
Safety Instructions Important Safety Instructions (cont.) b) 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 swim spa water temperatures to 38˚C (100˚F). c) B efore entering a swim spa, the user should measure the water temperature since the tolerance of water temperature- regulating devices varies.
Safety Instructions Important Safety Instructions (cont.) DANGER – To reduce the risk of injury to persons, do not remove the suction grate. Suction through drains and skimmers is powerful when the jets in the swim spa are in use. Damaged covers can be hazardous to small children and adults with long hair. Should any part of the body be drawn into these fittings, turn off the swim spa immediately. As a precaution, long hair should not be allowed to float in the swim spa.
Safety Instructions Important Safety Instructions (cont.) T he unit should be subjected to periodic routine maintenance once every quarter to make sure that the it is operating properly. DANGER – Risk of Electric Shock. A green colored terminal or a terminal marked G, GR, Ground, Grounding or the symbol shown in Figure 14.1 of UL 1563 is located inside the supply terminal box or compartment.
Safety Instructions Warning: Children should not use swim spas or hot tubs without adult supervision Avertissement: sans surveillance Ne pas laisser les enfants utiliser une cuve de relaxation Warning: Do not use swim spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
Safety Instructions Warning: Do not use a swim spa or hot tub immediately following strenuous exercise Avertissement: Ne pas utiliser une cuve de relaxation immédiatement aprés un exercise fatigant Warning: Prolonged immersion in a swim spa or hot tub may be injurous to your health Avertissement: L’utilisation prolongée d’une cuve de relaxation peut être dangereuse pour la santé Warning: Do not permit electric appliances (such as light, telephone, radio, or television) within 1.
Operation Instructions The only user controllable components are jet pumps 1, 2, e-stop/timer, and the Wave propulsion system. E-STOP The E-stop is installed to allow for quick power down should an emergency arise in or around the spa. Simply pressing the e-stop will cut power to the jet pumps, filter pump, and propulsion system until the e-stop is reset. The E-stop can be reset by twisting the button counter clockwise.

Typical Code Requirements If the authority having jurisdiction makes a regular inspection of the spa to determine compliance with applicable permit or requirements, the spa owner and/or operator shall correct all noted deficiencies before placing the spa in operation and accessible to users.
Water Chemistry Terms You Should Know Before jumping into the Spa Water Maintenance, here are some terms to help you. 1. Parts per million, or ppm: This is a form of measurement used in most spa chemical readings. Best described as any one million like items of equal size and make up, next to one unlike item, but of equal size. This would be one part per million. 2. Total Alkalinity: This is a measurement of the ability of the water to resist changes in pH.
Water Chemistry Terms You Should Know 7. Sanitizers: This is what kills the germs and bacteria that enter the water from the environment and the human body. A. Chlorine 1. Chlorine is an immediate sanitizer. B. Bromine 1. Two types of tablets. a. Hydrotech b. Lonza 2. B romine is a slow dissolve chemical and may take a few days to develop a reserve or reading in the water. 8. Total dissolved solids (TDS): Materials that have been dissolved by the water. i.e.
Basic Chemical Safety Guidelines Keep all chemical containers sealed and out of reach of occupants Read and follow all label directions NEVER mix products Accurately measure products Store products in a cool, dry place Never store products in direct sunlight Always handle products with great care Proper ventilation shall be provided for rooms where chemicals will be stored and used Never store basic and acidic chemicals near each other 31
WATER QUALITY MAINTENANCE START-UP Step 1: Your spa should be filled using a Pre-filter, which can be obtained from your local dealer. This Pre-filter will help remove many of the minerals existing in the water, which will make adjusting the water balance easier after a new fill. Step 2: During the initial filling of the spa, add a sequestering agent to combat suspended minerals in the water. The agents are sold under many different names such as Mineral Clear, Stain and Scale, and other brands.
SPA WATER MAINTENANCE – START-UP USE ONLY SPA CHEMICALS (some pool chemicals are not suitable for spa use). *M aintaining your sanitizer at the recommended levels at all times will decrease the occurrence of unsafe bacteria in your spa water. *W hen adding chemicals, broadcast chemical across a large amount of surface area to prevent a high concentration in a small area. 1. Clean the surface with a spa general purpose cleaner or wipe down with a clean wet towel. 2.
Spa Water Maintenance: Trouble-Shooting Guide Problem Possible Causes How To Fix It Sanitizer Odor • Excessive sanitizer level • Shock water with non-chlorine shock treatment • Low pH • Adjust pH if necessary Water Odor • Low levels of sanitizer • Shock water with non-chlorine shock treatment or adjust sanitizer levels • pH out of range • Adjust pH level if necessary • Bacteria or algae growth • Adjust sanitizer if necessary Cloudy Water • Dirty filters or inadequate filtratio
Why Water Maintenance is Important in a Spa 1. Evaporation: As water evaporates, only pure water evaporates, leaving the salts, minerals, metals, and any unused chemicals behind. Adding water adds more salts, minerals, and metals. In time, the water can become saturated with these dissolved solids and can cause stains or scale to form on the walls of the spa or a scale build up inside the equipment. Colored or cloudy water, and possible corrosion of plumbing and fittings may also occur. 2.
Spa Water Maintenance Recommendations The spa requires periodic draining and cleaning to ensure a safe, healthy environment. It is recommended that you clean your spa at least every 180 days. Heavy bather load will require cleaning it more often. CHEMICAL TEST FREQUENCY • S pa water should be tested at least every day. More frequent tests should be conducted during high bather load conditions.
Winterizing Your Spa 1. D ue to the physical size of the spa, we recommend draining your spa with a submersible sump pump. Draining your spa with a conventional spa drain is not a reasonable option in some cases. 2. Loosen all pump unions 3. Remove winterizing plug from face of the pump(s) where applicable. 4. Using your shop vac in a blowing mode, insert the hose into the nozzle of each jet and blow the trapped water from the lines into the interior of the spa. 5.
INSTRUCTIONS FOR MULTIPLE DAY PERIODS OF NO USE OF SPA 1. W ater chemistry shall be monitored and adjusted for various bather load conditions such as multiple day periods of no use of spa to prevent under and over chlorination. This is particularly important when a sanitization system that does not measure sanitization level is installed. 2.
SPA TROUBLE-SHOOTING GUIDE WARNING - Service and repair shall only be performed by a qualified technician. Customer shall not attempt to repair serviceable or non serviceable parts. Exceptions: • Clean/replace filter cartridge • Replenish chemical feed system as directed by service professional Propulsion System Breaker trips when turning the propulsion system on/off 1. V erify that the G.F.C.I. installed on the input power line to the propulsion system is protected by the factory supplied G.F.C.I. 2.
