    No. 6 AWG. Proper Use and Installation ThermoSpas has made every effort to provide you with a safe and reliable product. The detailed instructions provided previous to, and with the receipt of, your spa will explain how to safely in- stall, operate and maintain your spa.
  • Page 8 DANGER: RISK OF SEVERE INJURY FROM ELECTRIC SHOCK OR DEATH FROM ELECTROCUTION! • Install the spa at least 5 feet (1.5m), from all metal surfaces. As an alternative, a spa may be installed within 5 feet of metal surfaces if each metal surface is permanently connected (bonded) by a minimum No.
  • Page 9 • 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. • Persons suffering from any condition requiring medical treatment, the elderly, or infants should consult with a physician before using a spa.
  • Page 10: Spa Safety Literature

    Spa Safety Literature To ensure you have a safe and enjoyable spa experience, learn all you can about spa safety and emergency procedures. Especially useful are the brochures listed below: • Children Aren’t Waterproof • Pool and Spa Emergency Procedures For Infants and Children •...
  • Page 11: Be Aware Of The Risk Of Fatal Hyperthermia

    DANGER: RISK OF SEVERE INJURY OR DROWNING! Limb entrapment: May occur when a limb becomes entrapped, inserted or sucked into a suction or outlet opening. • Always keep suction fittings, suction covers, filter, filter lid or skimmer assembly in place when operating to avoid limb entrapment.
  • Page 12: Choosing A Location

    Site preparation, alterations to home owner’s property and permits (if any) are the sole responsi- bility of the owner. ThermoSpas spas are not intended for commercial applications. WARNING: For spas that are to rest on balconies, roofs or other platforms not specif- ically tied into main structural support, consult a professional Structural Engineer with experience in this type of application.
  • Page 13: Indoor Location

    • In the unlikely event that you should ever need to access or gain entry to any portion of the spa for servicing, it is highly recommended that you plan your outdoor installation to provide full access to the entire spa. Please take this into consideration when placing the spa in a deck or enclosed by a surrounding.
  • Page 14 Water damage to the home owner’s property from splashing or leaks are at the home owner’s risk. This is not covered under any ThermoSpas warranty. • Adequate ventilation must be provided in order to allow for chemical fumes to escape. Take into consideration that these fumes could enter other indoor areas.
  • Page 15: Electrical Set Up

    Before beginning the wiring process turn off the circuit breaker so that no power is connected to the controller. ThermoSpas recommends all spa wiring to be done by a licensed electrician. Improper wiring may void your warranty.
  • Page 16 The electrical requirements for your spa are found on the Electrical Guide Sheet contained in the Welcome Kit for your specific model. It is very important to review your electrical requirements before starting installation. Electrical Service Considerations The Electrical Service determines how many pumps can run in conjunction with the heater. If the dedicated GFCI circuit was installed with a smaller breaker than the recommended size (typically 60 amps), your heater will automatically shut off to avoid tripping your circuit breaker if too many pumps are activated (including the blower).

    Spa Start Up Please read through all steps before beginning. This section explains the necessary procedures required to start up your spa. Familiarize yourself with this procedure prior to beginning the pro- cess. Use this procedure as a guideline. • Make sure you have any instructions along with the Welcome Kit and Chemical Starter Kit prior to filling your spa.

  • Page 20 Avoid using any biguanide or copper-based algaecide with your spa. Use of these products is not recommended by ThermoSpas and may void your warranty. CAUTION: RISK OF PERSONAL INJURY OR SPA DAMAGE! Never add chlorine tablets (trichlor) or acid to your hot tub for any reason! These chem- icals may damage components within your hot tub, burn or irritate your skin, create a rash, and void the manufacturer warranty for your spa.
  • Page 21 Improper water chemistry may cause skin irritation or facilitate the transmittal of disease. Proper water chemistry is the sole responsibility of the spa owner. The costs incurred from injury or damage resulting from improper water chemistry are not covered under the ThermoSpas, Inc. warranty.

  • Page 41: Drain And Refill

    Note: You can use a submersible pump. Completely dry the shell surface with a soft, clean cloth. Clean the shell surface of any debris or mildew using ThermoGloss and ThermoSpas’ All Purpose Cleaner. Once you have completed all task above, make sure the drain valve is in the “OFF” position and reinstall the drain cap.
  • Page 42: Cleaning The Cover

    Note: Some residual foaming may occur, if so, use ThermoSpas Foam Away to suppress foam. Remove filter(s) and clean. Before spa is drained, empty contents (16 fl. oz.) of ThermoSpas Jet Line Cleaner in to warm spa water. Turn pump(s) “on” and run jets for 15 minutes. (Ensure filter is not in spa and cover is closed.)
  • Page 43: Shell Surface Cleaning

    The perfect product for cleaning the shell surface above the water line (when the spa is filled) is ThermoSpas All Purpose Cleaner. This helps to prevent a scum line from forming. Because it is a natural enzyme, it will not affect the water’s chemistry, it’s safe to use, it won’t scratch the acrylic, and it helps to eliminate mold or mildew odors without bleaching the surface.
  • Page 44: Winterizing (Closing Your Spa)

    Winterizing (Closing Your Spa) If you do not plan to use your spa during freezing weather, you will have to winterize it. Failure to winterize your spa will cause irreversible damage (in freezing temperatures) to the pump and plumbing lines. Winterization of your spa is easy.

  • Page 53: Glossary

    Glossary Activator (Potassium Monopersulfate) - Also known as non-chlorine shock, it is a strong oxi- dizer capable of eliminating contaminants from your spa. It is a non-chlorine chemical compound often used for shock treatments in spas and pools. It is very popular for use in mineral purifica- tion systems.
  • Page 54 Copper - Copper in water is a common problem in many households. Copper is present due to the corrosion of plumbing materials from Acidic (low pH) or Aggressive water (low TDS). Common problems associated with copper due corrosion are leaks in the plumbing system or blue-green staining.
  • Page 55 Media - The selected materials in a filter that form the barrier to the passage of certain suspend- ed solids or dissolved molecules. Mineral Purification System (ThermoClear Cartridge) - Mineral cartridges are placed in your filter core and release silver and copper ions into the spa water. These ions kill bacteria and virus’s.
  • Page 56 Safety Cover - A spa cover which meets strict ASTM standards for strength, construction, and anchoring, which reduces the drowning risk to small children. (Our covers are built to the ASTM safety standard). Not all hot tub covers on the market meet this important rating. Sanitize - Means to kill all bacteria, algae, disease-causing organisms, and any other uninvited guests.
  • Page 57 ThermoGloss - This product is an acrylic gloss that provides a tough coating to protect your shell from scratches and scale build up. Designed for hot water environments, this product will not break down and cause problems in spa water. ThermOzone - The only automatic ozonator with an EPA approved, built-in de-gasser tank that eliminates all offensive and potentially dangerous gases.
  • Page 58 Q: Can I change sanitizers? The use of ThermoClear and Chlorine can be interchanged in the same spa water. All other sanitizers require the draining of the hot tub. We recommend the use of ThermoSpas’ Jet Line Cleaner for cleaning out the lines.
  • Page 59 Q: What can I do if th pH is my spa is high (over 8.0) and will not come down? Follow the steps below. Turn on all pumps and add 1 ounce of ThermoSpas pH Down. Wait 15 minutes and retest the pH.
  • Page 60 Q: How do I change my filters if my pump circulation pump runs for 24 hours? On some models of Thermospas it is almost impossible to change the filters while the pump is on so the spa must be put into standby mode or power turned off at the circuit breaker.

    Q: I have a brand new hot tub and it is leaking. I need a service man right away. Firstly, there are a few things we will ask you to do. Describe that area of the spa where the leak seems to be coming from. Remove one of the skirt panels in that area and check your pump(s) union connections.
