NOTICE: All Captive Air® Tanks except Model 390.291352 are designed to operate in the vertical position. When using a submersible pump, the manifold and switch assembly must be installed in the pipe line as close to the center of the tanks as possible. See Figures 8 and 9. The tank is shipped from the factory with a pre-charge of air. This system DOES NOT require the use of any outside air charging devices such as air volume controls on jet pumps, or bleeder orifices on submersible pumps.

To determine pressure switch setting, see pump owner's manual. If your pump pressure switch cut-in setting is less than forty (40) pounds, the tank air pressure MUST be reduced to this cut-in pressure switch setting (see table). To do this, bleed air from the valve located on top of the tank. Check pressure frequently with an accurate tire pressure gauge until correct pressure has been reached. , Conventional pump pressure pumps are as follows: switch settings CUT IN/CUT OFF PRECHARGE 20/40 PSI 20 PSI 30/50 PSI 30 PSI 40/60 40 PSI PSI on SEARS NOTICE: For years of trouble free service, check precharge annually. See service hints (Page 7) for procedure. NOTICE: Release and expel all air out of the piping system and the water reservoir portion of the Captive Air® Tank. This is required on new installations, pumps requiring repriming and pumps that have been apart for service. To accomplish this, open faucets farthest away from tank and start the pump. Observe the sputtering water flow from faucets. This is a mixture of air and water. Allow pump to run until there is a steady Open and close faucets repeatedly has been removed. If air continues ing on suction air free stream of water. until you are sure all air to remain in system, check for leaks in pipside of pump system (Jet Pumps Only). If you have a submersible pump, remove the bleeder 015rices in the pipe (just below the well seal) and replace bleeder orifice with pipe plugs.
