• 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.
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 •...
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.
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.
• 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.

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.
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.

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).

Topside Control Panel Main Control Panel Button Functions: Pump 1 Button: Press once to turn Pump 1 on low speed; a second time for high speed; a third time to turn off. Pump 2 Button (if equipped): Press once to turn Pump 2 on; press again to turn off.
Operating Instructions Setting the Temperature The LCD screen will constantly display the current water temperature, unless there is an error code or the spa needs attention. To set the desired water temperature: Figure 1 Press the Warm/Cool ( ) button, Figure 1. The current set temperature. Pressing the button a second time and any successive time will cause the set temperature to increase or decrease depending on what direction was last chosen.
Jets Therapy Jets Popular spa jets with powerful directional streams. These are easily controllable to give you just the right amount of massage. Turn the outer ring to open or close the jet to control the power. The nozzle can be adjusted by simply touching it and pointing it to the desired location on your body.
Programming Instructions Programming the Duration, Frequency and Temperature Setting Filter Cycles set the amount of time Pump 1 automatically operates in low speed to filter the spa water. The user can customize the duration and frequency of the filter cycles. At the beginning of the filter cycles, all pumps will activate to high speed for 1 minute to purge the plumbing lines of water, thus improving the overall cleanliness of the spa water.
Automatic Functions Over-Temperature Protection To prevent runaway heating of the spa, if the water exceeds 104°F the Filtration Cycles will be shortened to prevent excess heating of the water by pump 1 (minimum total filtration time per day will be 2 hours to maintain water cleanliness) until the water temperature decreases to the tem- perature set point.
Following the procedures below at the recommended intervals will insure that your spa provides years of service. If you have any questions concerning the maintenance of your spa please contact ThermoSpas’ Customer Care department.

Cartridge Clean filter cartridge by first filling a bucket with water, adding 8 oz. of ThermoSpas Filter Clean. Mix solution by moving filter cartridge up and down several times. For best results, allow filter to soak for 12 to 24 hours (never less than 3).
Spas with ThermOzone ThermOzone accomplishes water sanitation by using a powerful oxidant, Ozone. This 100% organic compound reacts with and destroys bacteria, mold, fungus, etc. Through a proprietary process, ozone effectiveness and air quality are maximized to provide optimal sanitation of your spa.
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.
You should perform this procedure just before you drain your spa. We recommend using ThermoSpas Jet Line Cleaner to dissolve the build up of body oils, dirt, hair, soap, scum, rust and mineral deposits which are the perfect breeding ground for bacteria and mold.
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.
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.

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. It is very popular for use in mineral purification systems. Algae - Algae may form on your spa surfaces or it may bloom in suspension.
Page 43
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). Com- mon problems associated with copper due corrosion are leaks in the plumbing system or blue- green staining.
Page 44
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 45
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 46
Total Alkalinity - The ability of the spa water to resist changes in pH. The “buffering” capacity of the water. Additions of Sodium Bicarbonate will increase the levels, expressed in ppm. Additions of Sodium Bisulfate decrease Alkalinity levels. Acceptable measurements range from 80 – 120. Total Dissolved Solids (TDS) - Is a measurement of the total amount of minerals, residue, and other particles that cannot be oxidized from the water and remain.
Page 47
Q: Can I change sanitizers? The use of ThermoClear and Chlorine can be used within 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.
