RULES FOR SAFE INSTALLATION AND OPERATION

NOTE: Installation must comply with all applicable state, provincial, and local statutes, codes and ordinances.Noncompliant installation may result in product failure, property damage, and/or personal injury.

1. 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.

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

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

4. Release all pressure before working on tank or system. Make sure all air pressure has been released before removing tank flanges.

5. BE SURE your pump electrical circuit is properly grounded.

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

Safety 2

Install in compliance with all applicable laws, codes and ordinances. Non-compliance may cause product failure, property damage, and/or personal injury. Install this tank in vertical position only. If your installation requires a horizontal tank, contact your dealer for available steel tanks.

LIMITED WARRANTY

PENTAIR WATER warrants to the original consumer purchaser (“Purchaser” or “You”) of the products listed below, that they will be free from defects in material and workmanship for the Warranty Period shown below.

Product Warranty Period

Water Systems Products –

whichever occurs first:

jet pumps, small centrifugal pumps, 12 months from date of original installation, or submersible pumps and 18 months from date of manufacture related accessories

PENTEK INTELLIDRIVE 12 months from date of original installation, or

18 months from date of manufacture Pro-Source™ Composite Tanks 5 years from date of original installation Pro-Source™ Steel Pressure Tanks 5 years from date of original installation Pro-Source™ Epoxy-Line Tanks 3 years from date of or iginal installation Sump/Sewage/Effluent Products 12 months from date of original installation, or

18 months from date of manufacture

Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence, misapplication, improper installation, or improper maintenance.Without limiting the foregoing, operating a three phase motor with single phase power through a phase converter will void the warranty.Note also that three phase motors must be protected by three-leg, ambient compensated, extraquick trip overload relays of the recommended size or the warranty is void.

Your only remedy, and PENTAIR WATER’s only duty, is that PENTAIR WATER repair or replace defective products (at PENTAIR WATER’s choice).You must pay all labor and shipping charges associated with this warranty and must request warranty service through the installing dealer as soon as a problem is discovered.No request for service will be accepted if received after the Warranty Period has expired.This warranty is not transferable.

PENTAIR WATER SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT DAMAGES WHATSOEVER. THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND IMPLIED WARRANTIES,

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 passing 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 system 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).
