Installation Basics

• The smaller ozonators made for spas are relatively simple and easy to install if you have experience working with spa pumping mechanisms. You will not be able to fully replace your spa purification system with an ozone generator: while effective at removing odors and some particles, the pumps cannot spread enough gas through the water for full purification, since this would also be dangerous to humans. Be prepared to use another method, such as adding bromine to the water, to help purify it. You should also be careful when handling and using the ozonator, since ozone is a dangerous gas to inhale and can be extremely corrosive.
  
  Check your spa to see if it is ozone-ready or not. Ozone-ready features are common in many modern spas and include a telltale ozone jet at the bottom of the spa, equipped with both a water port and an air port. This jet should have a capped air suction tube leading back to the pump. If not, you will need to install this jet along with your ozone generator.
  
  Before you begin, make sure that your spa receives the required voltage for an ozonator. Spas tend to operate at 110 or 220 volts, so it is important your ozonator matches the spa voltage. Electrical systems should also be connected to a GFCI protected power source (which shuts down automatically in case of emergency). When choosing a place to install the ozonator, the generator itself must be above the water level.
  
  

Installing the Ozonator

• You can connect your ozone generator in one of several methods, depending on your spa system. One of the most common methods is the jet water line connection, in which the ozone is injected into the water by installing a venturi tube into one of your jets. This requires a double-looped tubing system above the water level with an air check valve. You can also use the main line connection method, more common for in-ground spas, in which the generator is installed to feed directly into the main water line with a bypass valve to maintain pressure. You can also use an existing jet and simply re-route it by cutting the tubing and connecting it to the check valve of the ozonator, making sure to form the double-loop above the water level first.
