Windsor™95 Radon Removal System b. Pump Control For instructions regarding the electronic pump control, refer to Appendix A. c. Water Leak Protection (Water Alarm) (Figure 1) The water alarm control and water alarm valve are designed to identify leaking problems and stop the incoming water. It is designed to monitor radon vent obstruction, high water and fitting leaks. It does this by incorporating a water sensor in the control to signal the water alarm control to close the water alarm valve. Important Feature: Under normal conditions, the control will flash 3 lights every 10 seconds. Users Guide: • The control will beep if there is a vent pipe obstruction or leak detected, and at the same time a signal will be sent to the valve. This signal will cause the valve to close and cut off the water supply immediately. • To reset the valve to its original open position, press the open button on the control. • When the battery is low, the control will beep for 8 hours and then close the valve. If this occurs, replace the 2‐ AA batteries and press the open button. 3 LIGHTS POWER BUTTON CLOSE ...
Windsor™95 Radon Removal System 4. Installation 1. Be sure the fill float switch is not tangled around the pump by removing the pump and visually inspecting the float. Be sure the fill float switch is free to float up and down. 2. The Windsor™95 comes with a standard 2.1 gallon water expansion tank. Plumb this expansion tank near the water outlet of the Windsor™95. Note: This expansion tank can be used for a certain amount of water heater thermal expansion. If you have a tank type water heater, check manufacturer’s requirements for sizing a thermal expansion tank. Radon Testing Note: It is important to install a new sample valve or boiler drain in new piping so that the radon testing is not influenced by old piping. 3. Set the main tank of the Windsor™95 in the desired location that can hold the weight of the Windsor™95 shown in the Specification Section on page 3. Choose a flat, level surface with ample set‐up space. 4. In case of a malfunction, the unit could overflow. The Windsor™95 is fitted with an overflow pipe. (The overflow pipe is mounted near the rear of the unit. See Figure 2) Take this into account when positioning the unit. It is best if the unit can be positioned near a drain or sump pit with a sump pump. Important note about overflow: For added protection against overflow, use the overflow connection. Caution! Normally, the output from the pump is at a pressure of 70 PSI. This should not create a problem in an installation where the existing plumbing is in good condition. However, in an installation where the existing plumbing cannot withstand the operating pressure of the Windsor™95, the output from the pump may produce a stress on the ...

Windsor™95 Radon Removal System 5. The Windsor™95 requires a duplex outlet wired to a dedicated 20A circuit. This circuit should use #12 AWG wiring, follow electrical codes. 6. Install the 2.1 gallon water expansion tank on the outlet side of the unit (See Figure 5). This tank is included to prevent the pump from starting and stopping quickly (“short cycling”) when there are short‐term demands for small amounts of water. 7. Install a pre‐filter (sold separately) on the inlet side to protect the solenoid from sediment clogging (See Figure 5). The pre‐ filter should be a sediment‐type filter with a 5 micron rating. Do not use a carbon‐type filter! 8. Attach the red handled bypass valve. 9. The bypass valve is included so that the unit can be taken out of service easily without interrupting the water supply. Plumb the inlet line and outlet line so that the well can continue to supply water if the bypass valve is set to the bypass position. 10. Pour one ounce of bleach into the blower attachment nipple to disinfect the unit. See Figure 2 for location of the blower attachment nipple. 11. Firmly slip the blower onto the blower attachment nipple and tighten clamp to secure blower to nipple. Caution! Do not use PVC pipe cement on this connection. Note: If drawing air from an outdoor source is desired, make sure that no moisture can get into the blower motor. A dryer vent kit can be modified by removing the flap check and replacing it with a screen. Be sure to install the kit as directed and run the hose down to the floor in the area of the Windsor™95. 12. Connect the following cords. Refer to figure 4. •...

Windsor™95 Radon Removal System 13. To start to fill, plug the yellow float switch cord and water alarm valve power cord into the dedicated GFCI 20 amp duplex outlet. Important note: Do not plug in pump control cord until the Windsor™95 tank is filled to normal operating water depth. 14. Run the vent line outdoors using 2” PVC piping. Try to make this line as short and direct as possible*. Make all of the pipe connections air tight using proper PVC pipe cement. Important note about vent line piping: Use ¼” per foot pitched down towards the Windsor™95. *Caution! Do not install a vent outlet line which is longer than 50’, and includes more than five elbows. This can create excessive backpressure and interfere with the operation of the unit. On longer runs, use larger pipe. Call the factory for details on specific applications. If this is done, the blower unit of the Windsor™95 can create pressure within the main tank. This can cause water from the main tank to be forced up through the overflow pipe and spill onto the water sensor, thus activating the water alarm valve and shutting down the unit. This can also occur if the vent outlet line is plugged. *Caution! Do not install the vent opening at a location where the vent gasses could be blown back into an occupied space. Important information about venting: Since the Windsor™95 unit removes radon in the water, the unit must be vented carefully. Common practice is to run the vent up past the roof line of the building. An elevated vent opening provides the best way of dissipating the radon gas. Protocols recommend extending the vent opening 2’ above the highest opening in the building, and at least 10’ away from the nearest opening. It is recommended to protect the vent opening with a vent screen. A single free hard (printed) copy of the ASTM E‐2121 standard (Recommended Residential Radon Mitigation Standard of Practice) is available from EPA’s National Service Center for Environmental Publications (NSCEP). You can order a copy by phone at 1‐800‐490‐9198, ...

EPA reprints E‐2121 under agreement with ASTM International. 15. Plumb the electronic pump control and plug the pump cord into the female pump control cord (See figure 4). 16. Check all plumbing fittings to be sure all fittings are water tight. 17. Be sure the water alarm valve control is wired to the power supply, motorized ball valve, and floor water sensor. 18. Install 9V battery backup into water alarm control. 5. Start Up Procedure 1. Set the red handles on the bypass valve to the Service position. 2. Plug the water alarm valve control power cord into the non‐GFCI outlet. 3. Plug the yellow cord into the GFCI outlet. The blower should start, and the solenoid valve should open to begin filling the tank. 4. As the water level in the tank rises, the fill float switch will tilt up. This will stop the blower and close the solenoid valve. The tank is now full. 5. Once the tank is full, plug the black pump control cord into the outlet to start the pump. 6. If the pump does not start delivering water to the house, it may be necessary to prime the pump. (Normally you will only have to do this once, when the unit is first installed.) The pump is suspended by a pipe underneath the pump control. Unscrew the ...
Windsor™95 Radon Removal System the treated water to ensure that the unit is reducing radon levels in the water. Radon Testing Note: It is important to install a new sample valve or boiler drain in new piping so that the radon testing is not influenced by old piping. 9. Perform the six‐month maintenance procedure, and fill out the Start‐Up Data page at the end of this manual. 6. Operating Instructions Once the Windsor™95 has been installed, it should operate with very little attention. Normal Operation Main Unit The unit should not need any operator attention. When water is used in the house, the 2.1 gallon water expansion tank delivers water demand. When the pressure drops to the set pressure, the electronic pump control starts the Windsor™95 pump to deliver water to the home and refill the 2.1 gallon water expansion tank. When the electronic pump control senses normal household pressure, the pump control shuts the Windsor™95 pump off. As the water level falls in the Windsor™ main tank, the float switch powers the blower and solenoid to fill the Windsor™95 tank with treated water. Low Water Cut‐Out Protection The electronic pump control will automatically stop the pump when there is low water in the Windsor™95 tank. The pump will automatically try to restart for 30 minutes. If water is not replenished during this time, manually pressing reset is required to ...
Windsor™95 Radon Removal System Water Alarm The water alarm control and valve is in place for protection against low battery, leaking or overflowing and will not operate unless one of these things happens. Once the water alarm control senses a problem in the system, the water alarm control activates the water alarm valve and shuts off the incoming water. The water alarm control will also sound an alarm to identify that there is a problem. Bypassing the Unit If a problem develops, the Windsor™95 unit can be taken out of the water supply system with the bypass valve. The rest of the water system will operate normally, but the Windsor™95 will not be able to provide any protection against radon in the water. Caution! Do not continue to operate the water supply system this way for a long time. Correct the problem and return the Windsor™95 to service as quickly as possible. 7. Maintenance Every six months: • Check the operation of the fill 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 2.1 gallon water expansion 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. The tank in the Windsor™95 unit should fill in less than two minutes. • Check the outlet of the vent line to ensure that it is not blocked. • Check that the water alarm valve is operating correctly by ...

If the mineral layer includes a rusty material, you may have to use a reducing chemical to dissolve and neutralize the rust. 13. As a final step, sanitize the inside of the tank using a dilute solution of chlorine bleach. Rinse, then vacuum out any remaining water. 14. Re‐install pump and cover. Check the gasket to make sure it is properly sealed. Replace the gasket if necessary. Screw in the 3 thumb bolts. 15. Reconnect the water piping to the bypass valve. 16. Disinfect the unit. (Pour one ounce of bleach into the blower attachment nipple.) 17. Install the blower. Firmly slip the blower onto the blower attachment nipple and tighten the clamp. 18. Set the bypass valve to the Service position. 19. Restart the unit. Follow the instructions in the “Startup Procedure”. 20. Check all seals to ensure they are air or water tight. 8. Troubleshooting Low‐Water Pump Cut‐out If the Windsor™95 main tank has no water, the pump controller will turn off the pump to protect it from running dry. The pump will automatically try to restart if the water level returns to normal. If the water alarm valve or solenoid is stuck closed, incoming water will not be allowed to enter the Windsor™95 main tank. This will cause the tank to empty and the controller will turn off the pump to protect it from running dry. If the well pump fails there will be no water entering the main tank of the Windsor™95. This will also cause the controller to turn ...

Windsor™95 Radon Removal System This situation can be caused by using more water out of the Windsor™95 than what is coming in. A few inlet flow problems are: low yield well, well pump failure, clogged plumbing or water filtration restricting water flow filling the Windsor™95. No water from the Windsor™95 (alarm is sounding) Cause: The Water Alarm Valve shut water off to the Windsor™95. The Windsor™95 includes a water alarm valve which sounds an alarm and stops water filling the Windsor™95 when a leak or overflow condition is detected. Once water stops filling the Windsor™95, continued water use will cause the pump controller to stop the Windsor™95 pump from delivering water flow to the house. Examples: The alarm conditions to cause the water alarm valve to close and stop water from entering the Windsor™95 are: water sensor detects water on top of the Windsor™95. These conditions are caused by water detection due to high water levels, water leaks, condensation, etc. Also, if the air vent piping is restricted the Windsor™95 blower cannot freely blow the air out of the Windsor™95. This will cause blower back pressure which will force water up the overflow pipe to be released through the breather vent, causing the water alarm control to detect an overflow of water. Vent piping back pressure can be caused by an obstruction, ice build‐up, water trapped in a reverse pitch, excess pipe fittings or pipe length. Water Alarm A few things can cause the water alarm to activate: • The water alarm control sensor is wet, repair leak and dry off the top of the Windsor™95. • Vent line is obstructed, forcing the water up the overflow and triggering the water alarm sensor. Clear the obstruction. • High water is sensed by the water alarm control due to ...
