A pool ozonator helps keep your water clear and reduces the bacteria and other contaminants that can live in the pool. Most in-ground and above ground pools are built to accept an ozonator, and there are several different models available. The following steps are only a guideline of what to expect when installing your ozonator, though there may be some variation with your model.

Step 1: Size and Voltage

Every pool ozonator is going to be a little different. These devices are available in different sizes to accommodate the volume of the pool, and may be wired to accept either 110 or 220 voltage.

To calculate your pool's volume, multiple the length times the width, and then multiply that number by the depth of the pool. Divide that number by 12 to get the total number of cubic feet. If you need to calculate the gallons instead, multiply the cubic feet by 7.5 for a rough answer.

Small pools will generally use a 110 volt power supply, while larger ones need the extra power of a 220 volt system.  Having too much power won't harm your pool, but using an insufficient system will noy clean the pool properly and may not last as long.

Step 2: Install the Ozonator

Most pool ozone generators connect on the outflow side of the pool pump. Mount the ozonator as indicated in the instructions that came with it. Be sure that the ozonator hoses are long enough to reach your pool hoses, and attach the device so that it will not get knocked around or create a trip hazard. Small ozonators may not mount to a surface at all, but larger ones will need to be mounted in the pump cabinet

To install the ozonator, first cut the pool supply line. Connect the pump side to the ozonator intake and the pool side to the ozonator outflow. Use hose clamps to secure the hoses.

Step 3: Attach the Timer

For best results, pool ozonators should operate on a timer. If one did not come with your ozonator, check with a pool supply store. You can set timers to activate the ozonator at specific times, keeping the pool clean and clear without inconveniencing swimmers who use the pools. Most timers connect with 3 to 5 color-coded wires, using a Phillips screwdriver. Once everything has been installed and tested, set the timer to run the ozonator 2 to 4 hours a day to keep the water clean and healthy.

Step 4: Test the System

Test the system by turning on the pool motor and the ozonator. The larger your pool, the longer the system will take to operate. In most instances, you will begin to see a noticeable clearing in the water color within 2 to 3 hours. Operate the ozonator for around 12 to 24 hours before using the pool.
