After a long day, there’s nothing more relaxing than sinking into warm, bubbling water right in your own backyard. The SaluSpa® Miami AirJet™ 4 provides a soothing massage experience for up to 4 people, while still being quick and easy to set up. This spa reaches up to 104ºF (40ºC) to provide ultimate relaxation as you are surrounded by 120 AirJet massage bubbles. Simply attach the pump and watch as it inflates. The patent-pending EnergySense® insulation is constructed with a multi-layered material that is designed to prevent heat loss. This innovative construction makes this hot tub up to 40% more energy-efficient than similar inflatable hot tubs, keeping your hot tub temperatures high and your energy usage low. The AirJet system features 120 jets which release bubbles from the bottom of the spa to create a warm, bubbling hot tub environment. These soothing bubbles will help you relax and unwind right from the comfort of your home. The external wall is constructed with 3-layer Tritech® material, proven to be both puncture and damage resistant. This material offers exceptional stretch resistance, allowing the spa to maintain its intended shape over time, no matter how many times you inflate and deflate it. The included Freeze Shield® automatic heating function prevents inner components from freezing during colder temperatures. Designed with innovative winterizing technology, the system will keep the internal temperatures between 42º and 50ºF (6º and 10ºC) to prevent damage. Our spas feature a Ground Detection System that ensures the spa is used with an outlet having a proper ground connection, providing additional electric current protection. Only use a grounded socket corresponding to the electrical rating of the attachment plug. NEVER use an extension cord or multi-plug adaptor. Be sure to regularly inspect both the plug and socket for signs of damage, and do not plug the product back into the socket if damage is found. Read the manual thoroughly before setting up your hot tub. Equipped with a pump that quickly inflates the hot tub, heats it up, runs filtration and controls the massage system, this spa is both easy and convenient. The pump can easily be reached from inside the hot tub and features cup holders for drinks and snacks. Also included is a ChemConnect® dispenser that maintains clean, healthy water by evenly dispersing the proper amount of chlorine. This hot tub comes with a reinforced cover designed to lock in heat when not in use and keep dust and debris from collecting on the water.
