CSV1W Standard Installation Instructions NOTE: Submersible motor manufacturers recommend using a flow inducer sleeve to be sure the motor is sufficiently cooled at low flows. Pressure differential across the valve cannot be more than 125 PSI. Please read all instructions before installation. 1) Be sure that the well has been pumped clean before any valve installations. It is also important that all lines including the pump be flushed clean of debris. Turn off power to pump and drain system. 2) Although this valve can be installed above ground, (see above ground install instructions) it was designed to be installed in the well below the pitless adapter, well head, or in the well pressure tank. Flow direction is indicated by the arrow on the valve body. This model is adjustable from 45-70 PSI but is factory set at 50 PSI (Note: Your pressure at the surface may be 5 to 10 PSI lower than 50 PSI because of lift and friction loss) . Pressure switch should be set at 35/55 PSI or 40/60 PSI if preset valve is installed in the well. When installing in the well , be sure the white cap and oring are snapped to the top of the valve before installation. This creates a water tight seal for the valve. This cap is not necessary if the valve is installed above ground. 3) If installing valve in the well with an above ground tank, pressure switch and other controls must be installed on the small line as close to the diaphragm type pressure tank as possible. Pre-charge pressure in the tank should be 2 psi lower than pressure switch start point. California Proposition 65 Warning: This product contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. (Installer: California law requires that this warning be given to consumer.)
