RULES FOR SAFE

INSTALLATION AND

OPERATION

Read the Owner’s Manual and Rules for Safe Operation and Installation Instructions carefully. Failure to follow these Rules and Instructions could cause serious bodily injury and/or property damage.

Install system according to local codes. Always test water from well for purity before using.

Check your local health department for testing procedure.

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

BE SURE your pump electrical circuit is properly grounded.

Remove bleeder orifices, air volume controls or other air charging devices in existing system.

Hazardous pressure. To prevent possible serious or fatal injury and/or damage to equipment, system pressure must be less than 100 pounds per square inch (PSI) (Models PSP19, PSP32 and PSP35) or 125 PSI (Models PSP50, PSP62, PSP85 and PSP119) under any circumstances. Failure to follow this instruction can result in tank blowup. If system discharge pressure can exceed listed pressures, install a relief valve capable of passing the full pump volume at listed pressures.

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 system to freeze.

GENERAL INFORMATION

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

NOTICE: Transport and install tank in vertical position ONLY!

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

Pressure Switch Setting Tank Precharge (PSI) 20-40 PSI 18

30-50 PSI 28 40-60 PSI 38

Tank Precharge Settings for use with PENTEK INTELLIDRIVE Variable Frequency Drives

Set the pressure tank’s pre-charge to 70% of the system operating pressure. When using an external set point as well as an internal set point, precharge the tank to 70% of the lower set point of the two. Some applications may require a different percentage when figuring the set point. Refer to your PENTEK INTELLIDRIVE operator’s manual for additional information.

Tanks

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

above vinyl water cell (Fig. 2A).

2. Water begins to enter tank – air is compressed

above water cell as it fills with water (Fig. 2B).

3. Pump-up cycle completed – air now

compressed to cut off setting of pressure switch (Fig. 2C).

4. Water being drawn from tank – compressed

tank air forces water out of water cell (Fig. 2D).

5. Water cell completely empty – new cycle ready

to begin (Fig. 2A).

Installation 4

Connect system pipe to tank flange. Use plastic or steel pipe as required. To prevent leaks, use Teflon tape or Plasto-Joint Stik threaded connections to tank.

NOTICE: To be sure that joint is not crossthreaded 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. Tighten by hand first; finish with pipe wrench for tight seal.

NOTICE: When replacing a standard tank in a submersible pump system, raise pump and discharge pipe far enough to remove bleeder orifices in discharge pipe and plug 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 setting of the pressure switch.

It is necessary to flush all air out of the piping system and water reservoir portion of the precharged tank. This is required on new installations, pumps requiring repriming and pumps that have been disassembled for service. Do this 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 leaking into the system; check for leaks in the piping on the suction side of the pump.

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. At the air valve in top of tank, check air pressure with a standard tire gauge. Air pressure should be 2 PSI below pump pressure switch cut-in setting.

3. If the air pressure is more than 2 PSI 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 pressure switch connected to power supply wires).

2. Remove pressure switch cover.

3. Open a faucet near tank.

4. Bleed pressure down 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 PSI below pump cut-in setting (28 PSI for 30-50 switch, 18 PSI for 20-40 switch, etc.) If not:

A. Adjust switch according to switch manufac-

turer’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 PSI 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 set-

ting. Make sure that pump will stop running in a rea son able 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 hammer on startup.

7. Re-check tank air pre-charge to be sure it is 2 PSI below pump pressure switch cut-in setting (see Page 3).

TESTING FOR WATER CELL LEAKAGE

1. Disconnect power to pump.

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

3. Remove valve cap from valve and release all pressure possible by depressing valve core. When air stops coming from valve, remove valve core to release remaining pressure.

4. Disconnect piping from elbow on tank flange.

5. Carefully turn tank upside down or lay it on its side.

Retained water in tank may cause

sudden weight shift when lowering. Support tank so that it cannot fall when being lowered or inverted.

6. If water cell leaks, water will run out of valve. If so, replace water cell.

WATER CELL REPLACEMENT

To be sure cover flange cannot blow off of tank, release all air from system before re moving nuts from cover flange.

1. Disconnect power to pump.

2. Follow steps 2 through 5 under “Testing For

Water cell Leakage”, above.

3. Remove nuts from tank cover flange. Tap cover

flange to break seal and remove. Base will come off with flange.

4. Water cell will not come out in one piece.

Hold water cell with pliers and cut wherever convenient with single edge razor blade or sharp knife. Continue holding and cutting until water cell is removed.

5. Clean and dry inside of tank.

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

A. Place water cell on clean surface with open-

ing to one end and flatten to force air out. Pull ends out flat (see Figure 3).

7. To help insert water cell, sprinkle outside of it with talcum powder. With tank on its side, push tightly rolled water cell into tank, hooking water cell neck ring over edge of tank head.

8. Insert arm in water cell and push sidewalls outward. It is not necessary to remove all wrinkles from water cell.

NOTICE: Don’t push water cell into tank further

than its own length. In a large tank, water cell can slip out of reach if pushed too far.

9. Clean tank head sealing surface and lip ring groove of cover flange.

10. Pull lip ring of water cell through tank opening and seat it against tank head.
