IMPORTANT INSTRUCTIONS BEFORE INSTALLATION

FAILURE TO FOLLOW THESE INSTRUCTIONS MAY CAUSE SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE.

1. All piping and electrical wiring must adhere to state and local codes. Check with appropriate community agencies, or contact your local electrical and pump professionals.

2. Install tank as close as possible to the pump pressure switch to reduce friction loss and elevation difference between the tank, water supply main, and switch.

3. After installation, be sure the pressure switch is set low enough to shut the pump off. If all valves are closed and the pressure switch setting is too high, the pump will run continuously without water ?RZ FDXVLQJ RYHUKHDWLQJ DQG GDPDJH WR WKH SXPS

4. A pressure relief valve must be installed in the piping adjacent to the Well Tank.

5. The following may cause severe damage to tank and/or piping and will void warranty. )DLOXUH WR SURWHFW WDQN DJDLQVW EHORZIUHH]LQJ WHPSHUDWXUHV 3XPSLQJ FKHPLFDOV RU FRUURVLYH OLTXLGV 3XPSLQJ JDVROLQH RU RWKHU ?DPPDEOH OLTXLGV 2SHUDWLRQ DW SUHVVXUHV JUHDWHU WKDQ UDWHG SUHVVXUH RQ GDWD SODWH with no relief valve. 3XPSLQJ OLTXLGV KRWWHU WKDQ )

Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manual for further assistance.

Failure to follow these instructions can cause the tank to explode and result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

Depending on your tank model, install a 125 P.S.I. or less pressure relief YDOYH GLUHFWO\ LQWR D ?WWLQJ RI WKH SOXPELQJ 3RVLWLRQ WKH YDOYH GRZQZDUG and provide piping so that any discharge will exit only within 6 inches DERYH RU DW DQ\ GLVWDQFH EHORZ WKH VWUXFWXUDO ?RRU %H FHUWDLQ WKDW QR contact is made with any live electrical part.

The complete pump, tank, pressure relief valve, pressure switch and piping system MUST be protected against below freezing temperature. Failure to do so could cause the tank to explode and result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

This Well Tank is designed and intended for cold (ambient temperature) water storage at a maximum pressure of 100 PSIG or 125 PSIG depending on your tank model, any use other than with cold water, or at a sustained or instantaneous pressure in excess of 36,* RU 36,* GHSHQGLQJ RQ \RXU WDQN PRGHO LV 816$)( $ SUHVVXUH UHOLHI YDOYH RI DGHTXDWH VL]H PXVW EH LQFRUSRUDWHG LQ WKH system. The relief valve must be selected to pass the full capacity of the pump when the pressure in this tank is 100 PSIG or more. Consult pump manufacturer for pump capacity at relief pressure. The manufacturer of this tank does not accept any liability or other responsibility for personal injury or property damage resulting from improper use, installation, or operation of this tank, or of the system of which it is a part.

The well tanks are designed for operation on water systems with working pressure not to exceed 100 PSIG or 125 PSIG depending on \RXU WDQN PRGHO 3UHVVXUH H[FHHGLQJ WKLV FRXOG EHFRPH KD]DUGRXV and will void any and all guarantees, either written, or implied.

IMPORTANT

It will be necessary to expel all air from piping after new installations, repriming and after pumps have been disassembled for repair. To SXUJH WKH DLU ?UVW RSHQ D IDXFHW WKH JUHDWHVW GLVWDQFH IURP WKH SXPS With the pump being allowed to run, wait until a steady stream of water is coming from the faucet. At this time, close the faucet for several short intervals.

If, after this, air in the lines still occurs, check on the suction side of the pump for piping leaks.

When standard type tanks are replaced with this tank, all air charging GHYLFHV EOHHGHU RUL?FHV DQG DLU YROXPH FRQWUROV PXVW EH UHPRYHG

The pump tank has been shipped with a factory precharge as indicated on Table 1. If your pump start-up pressure is different from the factory precharge, adjust the tank pressure with the tank empty to your pump start-up pressure. This can be accomplished by simply bleeding air from valve in the top of the tank with an accurate pressure gauge. Using the same standard air charging valve in the top tank, a tire pump can be used to raise the tank pressure. Raise the pressure slowly, checking it periodically with an accurate tire pressure gauge, until the desired pressure is reached.

FEATURES AND OPERATING CYCLES

SHELL constructed of light-weight GUDZQ VWHHO ZLWK HSR[\ ?QLVK SURYLGHV extra corrosion-resistance.

STRONG AND FLEXIBLE BUTYL DIAPHRAGM assures dependable tank service even with pressures up to 125 PSI.

DIAPHRAGM SEAL consists of locking retainer ring for positive separation of air and water.

LINING protects inner shell against rust in water reservoir.

START-UP CYCLE

The diaphragm is pressed against the bottom of the air chamber

FILL CYCLE

Water is pumped into the reservoir, which forces the diaphragm upward into the air chamber.

HOLD CYCLE

Pump attains cut-off pressure. Diaphragm reaches uppermost position. Reservoir LV ?OOHG WR FDSDFLW\

DELIVERY CYCLE

Pump remains off while pressure in air chamber forces diaphragm downward to deliver water.
