1. Read these Rules and the Instructions carefully.

Failure to follow them could cause serious bodily injury and/or property damage.

AWARNING] These water storage tanks arc designed for

Hazardous operation on cold well water systems limpressure ited to a maximum working pressnre of 100 pounds per square inch (PSI). If your water system can exceed 100 P.S.I., install a Sears No. 2729 relief valve on the system.

Failure to follow these instructions can canse tank blow-up and result in serious injury.

AND OPERATION

NOTICE: Ahhongh No. 2729 Relief Valve is set to open at

75 PSI, lot your safety Captive Air _Tanks are designed and rated to operate at up to 100 PSI.

2. Be sure installation meets all local plumbing, pnmp, electrical and well codes.

3. Always test water from well for purity before using. Call your local health department for testing procedure.

4. Before installing or servicing your pump, BE SURE pump power source is disconnected.

other than ff rigid piping is installed to elbow on inlet flange, BE SURE to support the piping.

For proper installation of your pump to tank, follow one of the typical installations on Page 4 and 5. Use Teflon tape on all threaded connections to tank.

Standard pipe fittings, such as nipples, tees and elbows must be purchased locally. If you are using a horizontal jet pump mounted on top of tank, Figures 5 and 6, Kit No.

2788 is required.

See Page 10 for contents of kit.

If your present system has an air volume control (AVC), remove it and plug AVC port on pump.

Complete pump, tank, and piping system MUST be protected against below freezing temperature.

Failure to do so could cause severe damage and voids the warranty.

OPERATION

BEFORE YOU START YOUR PUMP

Your tank is facto W charged with forty (40) pounds of air pressure.

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 rate tire pressure gauge until correct pressure reached.

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 air free stream of water.

If air continues to remain in system, check for leaks in piping on suction side of pump system (Jet Pumps Only).

If yuu have a submersible pump, remove the bleeder orifices in the pipe (just below the well seal) and replace bleeder orifice with pipe plugs.

OPERATION

C D

Tank is nearly empty:

Water storage bag is at bottom. Air expands to fill space above bag. The pump starts

FIGURE 10

Water starts to fill the bag:

As bag fills, air above the bag is compressed,

Bag is full to capacity:

Air is compressed to the utmost for maximum drawdown. The pump stops

Water is being drawn from the bag:

Compressed air in the

tank forces water out.

NOTICE: To prevent waterlogging, check tank air charge annually.

TO CHECK TANK AIR CHARGE

If dmwdown (amount of water that comes out of tank per pump cycle) decreases significantl}; check as follows:

1. Check air charge in tank.

Shut off electric power to pump, open faucet near tank, and drain completely.

2. At the air valve in top of tank, check air pressure with standard tire pressure gauge. Air pressure should bc the same as pump pressure switch cut-in setting.

3. If the air pressure is below the cut-in setting, add air to the tank. Use an air compressor or a portable air storage tank.

4. Use soap or liquid detergent to check for air leaks around air valve. Continuous bubbling indicates a leak.

If necessary, install new core in air valve. This is the same as those used for automobile tubeless tires.

SERVICE HINTS

TO CHECK PUMP PRESSURE SWITCH

1. Start the pump and allow the pressure switch to shut it off.

2. Check the tank air pressure with the tire gauge. It should be the same as the cut-off pressure tbr your system. (See

"OPERATION" section on Page 6 for correct pressures).

3. If the pressure reading is different from your system recommended pressure, the switch should be replaced.

REPLACEMENT OF AIR VALVE

If air valve hecomes broken, or leaks beyond repair, it may be necessary to replace it.

10. Wipe a thin film of soapy solution on top half of replacement stem and insert in stem hole in top of tank.

It is necessary to use a valve stem pulling tool to pull stem thru opening.

This toni is the same as used by your local filling station and Sears Automotive Center when servicing tubeless tires.

11. Pull neck of bag out of tank opening and seat in groove.

BE SURE ring groove is clean.

12. Clean sealing surface of cover assembly and place on studs.

13. Hand tighten all nuts on studs.

[_ CAUTION ] It is important that nuts be tightened as follows: First, hand tighten all nuts. Then tighten one nut to a snug fit. Next, tighten the one opposite to a snug fit. Proceed, tightening the others in opposite pairs to a snug fit. Recheck all nuts in same opposite patterns to be sure they are evenly tightened and you have a good seal. DO NOT overtighten, as you may twist the studs off the tank.

With a torque wrench, tighten to 85 inch pounds.

14. Tip tank upright and assemble for operation.

15. Recharge tank with proper amount of air.
