The ozonator should be firmly mounted by the spa or by the spa's equipment sometimes under the cabinet in portable spas. The ozonator is hooked up to a power source. The ozone tubing is connected to the ozonator at one end and into an air pipe of the spa's jet piping on the other end. When water runs through the spa's jet piping, a suction is created in the air piping attached to each jet.
This is called the "Venturi Effect". That suction is what actually pulls sucks the ozone gas from the ozonator. The gas is then mixed with the water and small ozone bubbles are injected into the spa through the jet that is closest to the ozone tubing. Step 1 - Mount ozonator.
Decide where you want to mount the ozonator itself. Normally this would be under the cabinet of a portable, self-contained spa - or near the spa pack of an in-the-ground component type spa system.
Sometimes it is necessary to mount the ozonator under a deck, or on the wall of a spa room. Wherever you decide, there should be adequate air flow around the unit. Step 2 - Hookup electric power to the ozonator. There are many ways to do this. Different ozonators come with different type plugs on the end of the cord.
Some brands do not come with any plug, just wires. Each installation is a little different.
An easy and effective way to hook up the ozone line is to use an ozone injector. Cut the water line leading to a jet (choose a jet near the bottom of your spa if. The ozonator itself is connected to your spa control system, which supplies power and A simple way to hook up the line is to use an ozone injector, which is a.
You can plug the unit into a standard volt outlet, if one is available nearby - but the unit will always be on. A more common installation is to hookup the ozonator directly to the timer of the spa pack.
This way it is GFCI protected as well as the unit only comes on and off when you have your timer set. Another way is to hook it up directly to the GFCI of the spa. This way it is GFCI protected, but it will always be on. There are 2 schools of thought when it comes to deciding whether or not to hook up the ozonator to a timed electric source or to hook it up to a constant powered source. We will not make a value judgment here, but we will simply tell you the two opposing viewpoints and you can make the best decision that you feel comfortable with.
Some manufacturers and Spa Guys feel strongly about 1 and some feel strongly about 2. You decide which is best for you. School 1 - Definitely hook it up to your timer circuit. This will save the life of the bulb.
Why keep the bulb burning 24 hours per day when you will only be using the ozonator 6 hours per day? School 2 - Definitely hook it up to a constant power source. These bulbs will last years when kept on continuously. Constantly turning them off and on will reduce the bulb life and cause undue strain on the ballast. Step 3 - Hookup venturi assembly. Decide where you want to cut into your jet air piping. Usually you will want to choose a location that is closest to the ozonator and easiest to work on.
The ozone tubing must be tapped into the air pipe line or air control tube see attached drawings. This will be your Venturi Assembly. A This can sometimes be accomplished with a saddle clamp that is often included with some ozonator brands. Drill into the air pipe and insert the saddle clamp fitting.
Attach the ozone tube to the fitting barb. B You can use an ozonator injector manifold that you can either build with commonly available plumbing fittings or commercially available prefabricated injector manifolds see attached drawing.
Cut the jet air piping and insert the manifold assembly. Attach the ozone tubing to the barbed fitting. C In some instances, you can simply drill a hole into the jet air piping, slip the ozone tubing into the hole and silicone around the tubing to keep it in place. Step 4 - Install check valve. The check valve is a safety device that will not allow any water to back up into the ozonator unit itself. When properly installed, water should never even be in the ozonator tubing, but there are instances when this could possibly happen - so it is best to use the check valve. You will notice that you can only blow into it in one direction.
Make sure that you install it the correct way or the gas will not be able to be sucked out of the ozonator unit. Once you have determined the proper direction of flow, cut the ozone tubing and insert the check valve at that point. Once more, blow into each end of the tubing to check that the flow direction is correct. Step 5 - Check all connections. One end of the ozonator tubing should be attached to the spa jet piping at your Venturi Assembly. Then it should run to the check valve.
Then it should be hooked up to the ozonator itself. Step 6 - Check for proper gas flow. Turn on the spa low speed. Make sure that any and all air control knobs valves on the spa are closed see attached drawing. They must always be closed or you will not get the proper seal for the Venturi Effect suction to take place. Good rule of thumb is to always have the air control knobs closed at all times except when you are actually using the spa.
When the air control knobs are closed, and the spa is running at high or low speed, you should see little air bubbles coming from the spa jet closest to the area where you installed your Venturi Assembly. Those bubbles will be ozone gas if the ozonator is on and will just be regular air bubbles when the ozonator is off.
Step 7 - Set up system timer. An ozonator should run for 3 hours per every 12 hours see Ozonator Facts information attached. It is best not to run it for 6 hours continuously. Whenever the pump is running, there is ozone being injected into the water. Then cut the same line off at the venturi air manifold and plug or cap this line at the manifold.
Cut the line right at the air manifold because you don't want to have excess line hanging. If water back-flows up the venturi system and settles in this dead end line, it may become a breeding ground for bacteria. If your spa has looped jetting, your jet will have air going in one side and out the other side to the next jet. Cut this jet out of the air loop and then reconnect the loop with 2 couplers and a length of flexible hose so you bypass the air on the jet you plan to use.
Connect the ozone tubing to one side of the jet and plug or cap the other side, as close as possible to the jet. Some jets have a barbed connector for the air as in picture and some have a slip connector. The air port is generally installed above the water port and will be smaller or the same size as the water port. Adapter fittings may be necessary to connect to the jet. The easiest way to connect to the air system is to find a convenient place to cut the plumbing and install a Tee connector on the line. Use a barbed connector on the third side of the T and slide the ozone line onto the barb.
