73808 Needle Valve
Needle Valve - Ozone Air Adjusting Kit for Freshwater 3 Ozonators.
The ozone tube connects to the injector and provides air to the ozone purification system to "inject" ozone into the circulation system. The injector is placed in the circulation system after the heater, circulation pump and bleedline. As water passes through the injector, a vacuum is created via the ozone supply hose. The vacuum draws air through the ozonator producing the ozone gas. The ozone then travels through supply tubing to the injector and into the spa water. The tiny bubbles coming from the heater return are ozone. The air at some point may be come excessive and create a good deal of noise. The air restrictor ( Straight Needle Valve) will reduce the amount of air and inturn reduce the noise. It should be noted that anytime air in introduced to the circulation line ( Ozone) noise will be present. No ozone in the spa will result in silent operation.
