Safety 3

To prevent possible serious or fatal injury and/or damage to equipment, system pressure must be less than 125 pounds per square inch gauge (psig) under any circumstances. Failure to follow this instruction can result in tank explosion. If system discharge pressure can exceed 125 psig, install a relief valve capable of pass-ing the full pump volume at 125 psig. Install relief valve in pump supply line to tank, as close to tank as possible.

Hazardous pressure. Read owner’s manual before attempting to install, operate, or service this tank.

To avoid possible equipment failure, severe injury, and property damage, do not allow pump, tank, or piping sys-tem to freeze.

GENERAL SAFETY

All tanks are factory pre-charged with air. When installing tank, adjust pre-charge to 2 psig below pump cut-in pressure setting. To do this, bleed air from or add air to the valve on top of the tank.

NOTICE: Always set pre-charge with NO WATER in tank.

Check pressure frequently with an accurate tire pressure gauge until correct pressure has been reached. For correct pre-charge pressure settings, see Chart 1, below.

CHART I

NOTICE: Replace and tighten air valve cap if it is removed for any reason. Failure to replace air cap may allow loss of air pressure and eventually lead to tank waterlogging and air cell failure.

Pre-charged storage tanks can be connected together to increase the supply of usable water (drawdown). Two tanks of the same size will double the supply and three tanks will triple the supply. See Figures No. 1A and 1B for typical installations of this kind.

OPERATING CYCLE:

1. Tank nearly empty – air expands filling area inside air cell (Figure 2A).

2. Water begins to enter tank – air is compressed in air cell as tank fills with water (Figure 2B).

3. Pump-up cycle completed – air pressure has reached the cut off setting of pressure switch (Figure 2C).

4. Water being drawn from tank – compressed air in air cell forces water out of tank (Figure 2D).

5. Tank now empty – new cycle ready to begin (Figure 2A).

INSTALLATION

Connect system pipe to elbow on tank flange. Use plas-tic or steel pipe as required. To prevent leaks, use Teflon tape or Plasto-Joint Stik1 on male threads of all threaded connections to tank.

NOTICE: To be sure that joint is not cross-threaded and that threads are clean, always make connections by hand (without sealer) first. After making sure that threads are clean, remove pipe, add Teflon tape or Plasto-Joint Stik, and remake connection. Do not over-tighten pipe connection at tank. Thread connection on hand tight plus 3 additional turns for steel pipe and 1-2 turns for schedule 40 PVC pipe.

NOTICE: When replacing a standard tank in a sub-mersible pump system, raise pump and discharge pipe far enough to remove bleeder orifices from the tees in the discharge pipe. Plug the tees. When replacing a standard tank in a jet pump system, remove Air Volume Control (AVC) and plug AVC port in pump.

In areas where the temperature is high for long periods of time, the tank pre-charge pressure may increase.

This may reduce the tank drawdown (amount of water available per cycle). If this occurs, reduce the pre-charge pressure to two PSI below the pump cut-in set-ting of the pressure switch.

It is necessary to flush all air out of the piping system and water reservoir portion of the pre-charged tank.

This is required on new installations, pumps requiring repriming and pumps that have been disassembled for service. Proceed as follows:

1. Open faucets furthest from tank and allow pump to operate.

2. Air in the system will cause a sputtering flow; allow faucets to run until you have a steady, air free stream.

3. Open and close faucets repeatedly until you are sure all air has been removed.

4. If stream does not become steady, air may be leak-ing into the system; check for leaks in the piping on the suction side of the pump.

NOTICE: To prevent waterlogging, check tank air charge every six months.

TO CHECK TANK AIR CHARGE

If drawdown (amount of water that comes out of tank per pump cycle) decreases significantly, check as follows:

1. To check air charge in tank, shut off electric power to pump, open faucet near tank, and drain completely.

2. Remove pole piece cap and check air pressure at the air valve in top of tank with a standard tire gauge. Air pressure should be 2 psig below pump pressure switch cut-in setting (that is, if switch closes at 30 psig, pressure in tank should be at 28 psig).

3. If the air pressure is more than 2 psig 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.

TO CHECK PUMP PRESSURE

SWITCH SETTING

1. To check pressure switch setting, disconnect power to pump at supply panel (but be sure to leave pres-sure switch connected to power supply wires).

2. Remove pressure switch cover.

3. Open a faucet near tank.

4. Allow water to drain until pressure switch contacts close; immediately close faucet.

5. Check pressure at valve with standard tire gauge or with pump pressure gauge (if supplied).

6. Pressure gauge should read 2 psig below pump cut-in setting (28 psig for 30-50 switch, 18 psig for 20-40 switch, etc.) If not:

A. Adjust switch according to switch manufacturer’s instructions.

B. Reconnect power supply to pump and pump up pressure in system.

C. Disconnect power supply to pump again and re-check switch setting.

D. Repeat until pressure switch starts pump within ±1 psig of proper setting.

E. If cut-in setting is too low, system will rattle or develop water hammer when pump starts.

F. Cut-out setting is not as critical as cut-in setting.

Make sure that pump will stop running in a rea-sonable time. If it does not, cut-out setting may need to be adjusted down slightly. Be sure that after readjustment, system does not rattle or ham-mer on startup.

7. Re-check tank air pre-charge to be sure it is 2 psig below pump pressure switch cut-in setting.

TESTING FOR AIR CELL LEAKAGE

1. Disconnect power to pump.

2. Drain all water from tank by opening faucet closest to tank.

3. Remove pole piece cap and valve cap from valve and charge air cell.

4. Check air pressure after 24 hours. If air cell leaks, pressure will drop. If so, replace air cell.

AIR CELL REPLACEMENT

To be sure polar boss cap cannot blow off of tank, release all air from system before re-moving capscrews from flange assembly.

1. Disconnect power to pump.

2. Follow steps 1 through 3 under “Testing For Air Cell Leakage”.

3. Remove valve core (see Page 6).

4. Remove valve cap, hex nut and washer from valve.

5. With a screwdriver, pry the clips out and remove them. Remove polar boss cap.

Figure 4: Remove Pole Piece Cap,Valve Cap and Retaining Nut, Clips, and Polar Boss Cap.

Installation 6

6. Air cell may not come out in one piece. Pull air cell up with pliers and cut wherever convenient with sin-gle edge razor blade or sharp knife. Continue pulling and cutting until air cell is removed.

7. Before air cell can be inserted into tank, it must be tightly rolled up as follows:

A. Remove valve core.

B. Place air cell on clean surface with opening to one end; flatten bag to force air out. Pull ends out flat (see Figure 5).

C. To get tightest possible wrap, start on one side and TIGHTLY roll air cell to other side (see Figure 5). Force out as much air as possible.

8. Push and turn tightly rolled air cell into tank (see Figure 6).

9. Shake air cell a few times inside tank to work wrin-kles out. It is not necessary to remove all wrinkles from cell.

NOTICE: Don’t push air cell into tank further than its own length. In a large tank, air cell can slip out of reach if pushed too far.

10. Clean tank sealing surface before installing top flange assembly.

11. Clean sealing surface and groove of polar boss cap;

install O-ring and polar boss cap on tank.

12. Pull valve up through polar boss cap.

13. Install metal washer and nut on valve.

14. Reinstall polar boss cap into top opening. Fasten it with two (2) red clips.

15. Recharge tank to proper air pressure and install valve cap and install pole piece cap (see Page 5).

16. Prime pump (see pump owner’s manual).

VALVE CORE REPLACEMENT

To be sure air valve and core cannot blow out of tank, release all air pressure from tank before removing valve core.

1. Disconnect power to pump.

2. Drain ALL water in system by opening faucet clos-est to tank.

3. Depress valve core to release ALL air pressure in tank. When air stops coming out of valve, remove core from inside of valve to release remaining pres-sure. Thread new valve core into tank valve and tighten.

NOTICE: Do not overtighten.

4. Recharge tank with air pressure (see Figure 3, page 5) according to Chart I, Page 3; install valve cap and pole piece cap; reconnect power to pump.

Tank is ready for service.
