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. Step 8 - Chemicals. You will still need to chemically treat the water to some degree. The ozonator will only help to sanitize the water.
Drain spa water every 2 - 3 months, depending on use. Refill spa with fresh water to recommended level. Test and adjust the pH of the water to 7. This will ensure that there is a small amount of bromine sanitizer in the water, even when the ozonator is off. Test water for Bromine, pH and Alkalinity. Adjust the Alkalinity to and the pH to 7. Rinse off the cartridge filter with fresh water.
They absorb surface oils and reduce "ring around the spa" at the water line. Call us anytime for water chemistry advice or to order any hot tub chemicals or accessories. Ozone is a gas like the ozone layer around the earth that is produced by ultraviolet light exposure to oxygen. When ozone gas is injected into spa water, it acts as a very powerful sanitizer and will kill off almost all of the bacteria present. Ozonated spa water will remain clearer longer than just using bromine or chlorine as the primary sanitizer.
Ozone water purification is times more powerful than ordinary water sanitizers bromine or chlorine. It does not give off that "chemical smell" normally found in pools and spas and tends to produce less skin and nasal irritation. An ozonated spa can usually go longer between water drainings than a spa using other sanitizer chemicals. How does it work? The ozone generator in a spa contains an ultraviolet light bulb.
The unit sucks in oxygen from the surrounding air and exposes it to this light source. The oxygen is transformed into ozone which is "O-3" gas. This gas is then sucked into the jet piping of the spa by the "venturi effect" which creates a suction that shoots the gas into the spa water through either a water jet or a special ozone fitting located near the bottom of your spa.
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. Ozone will be pulled into your spa when your venturi air controls are closed. Only use this method if your venturi air system works well and the valves close properly.
If your spa is filled with foam insulation and you can't access an individual jet or jet line, use an ozone injector on your main plumbing line. When you place an ozone injector on the main plumbing line, you need to plumb in a bypass so you don't add strain to your pump and drastically reduce the jet pressure when your pump is on high speed. You can purchase an injector with a by-pass already plumbed together or you can buy the separate pieces and assemble it yourself.
The ozone injector should be placed after your pump, heater and filter when possible. If you do not place it after your equipment, you may not have sufficient venturi pressure and the concentrated ozone may damage your equipment over time. A check valve is provided with most ozonators to prevent water from back-flowing up the ozone line and getting into the ozonator. After you connect the ozone line to your spa, cut the tubing at about 6". Then reconnect the ozone line with a barbed check valve. If the check valve is not labeled with the direction of the airflow, blow into the check valve.
Connect the end of the check valve that you can blow into, to the line that leads to the ozonator. Connect the end that you can't blow into, to the line that leads to the spa. Air must be able to travel from the ozonator to the spa, but water should be prevented from flowing from the spa to the ozonator. A second line of defense to prevent water from getting into an ozonator is to create a Hartford Loop.
Creating a Hartford Loop simply means to loop the ozone tubing up as high as you can before you connect to the ozonator. The loop needs to go above the water line for optimal effect. Many spa manufacturers make connecting the electrical very easy by pre-wiring a plug for your ozonator on the equipment panel. Look for a female plug-in that is labeled for an ozonator. Our ozonators are available many different cord options that are pictured on our individual ozonator pages. If your spa has a plug-in to accept an ozonator, you need to determine the voltage that the plug is wired for.
Most ozone plugs are wired for Volts even if the main power going to the hot tub is Volts. Check your spa owners manual if you are unsure or consult the spa manufacturer. If you do not have an ozone plug, cut the plug off and hard wire to your spa system. Have an electrician or local spa professional do the wiring for you if you do not understand electrical wiring.
Water and electricity do not mix and a mistake could be fatal! We will not be held liable for any injuries that may result from the installation or troubleshooting of any electrical components. If your spa has an electronic circuit board with terminals ready to connect to, please check with your owners manual or spa manufacturer for the required voltage. Ideally, the ozonator should be wired so it comes on when your low speed pump is on. If you wire to the low speed pump circuit or your spa timer, the ozonator will only be on when it needs to be, instead of 24 hours a day. If your spa has a timed filtration cycle, set the timer so your pump filters a minimum of 3 hours in every 12 hour period.
Ozone will only be getting into your spa when the pump is filtering and the longer you filter every day, the more effective the ozone purification process will be! Congratulations, your install is complete! Welcome to healthier hot tubbing and a much more enjoyable spa!
