Windsor™ Radon Removal System The Windsor™ unit from R.E. Prescott Co., Inc. is designed to remove radon gas from water. Radon is a radioactive gas which can cause serious health problems. Inside the unit, air is blown into the incoming water and allowed to bubble upward. This bubbling action releases the radon from the water. Air containing the radon is then collected and vented out.
Windsor™ Radon Removal System Inlet Flow and Pressure Specifications 7 gallons per minute and 50 psi required inlet flow and pressure. Outlet Flow and Pressure Specifications 7 GPM Pump Control w/ 1/2” Pex Figure 1 ‐ Windsor Outlet Flow vs. Pressure Controls and Indicators Bypass valve This stainless steel valve can be used to divert the water flow if a problem develops with the Windsor unit. This valve has a black handle, and is located near the back of the unit. See Fig. 4.
Windsor™ Radon Removal System Operating Instructions Once the Windsor has been installed, it should operate with very little attention. Normal Operation ‐ The unit should not need any operator attention. When water is used in the house, the one gallon draw‐down tank delivers water demand. When the pressure drops to the set pressure, the mechanical pump control starts the Windsor pump to deliver water to the home and refill the one gallon draw‐down tank.
Windsor™ Radon Removal System Note: If blower inlet is connected to draw air from an outdoor source, make sure that no moisture can get into the blower motor. If an outdoor source is desired, a dryer vent kit can be modified by removing the flap check and replacing it with screen. Be sure to install the kit as directed and run the hose down to the floor in the area of the Bubble‐Up® Interactive. Figure 2 – Circuit Box Wiring Connections 10.

Windsor™ Radon Removal System Maintenance Every six months: • Check the operation of the float, pump control, solenoid valve, and the blower by turning on a water tap and allowing it to run. At first, the water will be supplied by the 1 gallon drawdown tank, and then the pump should turn on. A few minutes later, you should hear the blower start and the solenoid valve should open. (The unit cannot remove radon unless the blower is working.) • Shut off the water tap.
Windsor™ Radon Removal System 5. 6. 7. 8. Loosen the 4 nuts on the pump access seal. See Fig. 3. Do not remove the top nuts so that the bolts do not fall into the Windsor main water tank. Note that the direction of the float switch cord is towards the air‐water coupling so that it can be re‐installed in the same position. Lift the pump access seal off of the main water tank. This may require prying with a flat screwdriver or two. Lift and pull out float switch and then pump from the main water tank.
