The sensor will function with either side placed toward the floor. 2. If the sensor will be used to detect another potential leak source, such as basement flooding, the sensor must be placed on a flat section of floor in an area where water will first collect. If the level cannot reach 1/32”, the alarm feature may not function. Do not place in a high-traffic area where the sensor could be stepped on or moved. The sensor will function with either side placed toward the floor. 3. After placing the

As in all plumbing products and water storage vessels, bacteria can grow in this Product, especially during times of non-use. Consult your local plumbing professional regarding any steps you may wish to take to safely disinfect your home’s plumbing system. DANGER! EXPLOSION HAZARD, WHEN THE WELL-X1™ HAS BEEN IN SERVICE AND A CHANGE TO A HIGHER PRE-CHARGE PRESSURE IS NECESSARY DUE TO A REQUIRED CHANGE IN THE PRESSURE SWITCH SETTING, FAILURE TO FOLLOW INSTRUCTION MANUAL CAN CAUSE A RUPTURE OR EXPL

This allows you to use the Well- X-Trol® “principle of separation of air and water” on larger jobs that are beyond the typical residential range. The Well-X-Trol® models we’ll be working with in this handbook are listed in Table 1. The design features of these larger models allow us to apply them more creatively than the smaller residential models found in the Well-X-Trol® 100, 200, and 250 series. The Larger Well-X-Trol®s are Designed and Built for Maximum Acceptance on Each Operating Cycle In

We now must select a pressure range (min. to max.) to establish pressurized delivery of water to the system and that we overcome elevation (static height) and friction loss of the piping. We must select a minimum pressure at the Well- X-Trol® location that will insure enough pressure to keep water flow under pressure at the top of the system…overcoming both the static height and the resistance to flow through the piping. We’ll do this by pre-charging the Well-X-Trol® to a pressure (P1) equal to

6. Slowly open the service valve to allow the system to pressurize. The pressure may drop slightly during this process. After the valve is fully open, open the fixture closest to the Well-X1™ to begin drawing water from the tank. 7. When the system reaches the factory cut-in (pump on) setting of 40 psig, the pump will start. Like a traditional mechanical switch, the pressure will begin to rise, repeating the cycle. If desired, the Well-X1™ settings can now be adjusted as shown below. OPEN CLOSES
