Always be sure to equip your well system with a proper Pressure Relief Valve. This should be capable of discharging the full output of the pump at or below the maximum working pressure of the lowest rated component in the system. See the owner’s manual for your pump for output information. This is vital for safe operation of the well system. THIS PRODUCT COMES WITH A 5 YEAR WARRANTY. SEE WATER WORKER LIMITED WARRANTY FOR DETAILS.
⚠ WARNING READ CAREFULLY THE PRODUCT INSTALLATION, OPERATING AND MAINTENANCE MANUAL. FAILURE TO FOLLOW THE INSTRUCTIONS AND WARNINGS IN THE MANUAL MAY RESULT IN SERIOUS OR FATAL INJURY AND/OR PROPERTY DAMAGE, AND WILL VOID THE PRODUCT WARRANTY. THIS PRODUCT MUST BE INSTALLED BY A QUALIFIED PROFESSIONAL. FOLLOW ALL APPLICABLE LOCAL AND STATE CODES AND REGULATIONS, IN THE ABSENCE OF SUCH CODES, FOLLOW THE CURRENT EDITIONS OF THE NATIONAL PLUMBING CODE AND NATIONAL ELECTRIC CODE, AS APPLICABLE.
⚠ THIS IS THE SAFETY ALERT SYMBOL. IT IS USED TO ALERT YOU TO POTENTIAL
PERSONAL INJURY AND OTHER HAZARDS.
OBEY ALL SAFETY MESSAGES THAT FOLLOW THIS SYMBOL TO REDUCE THE RISK OF
PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.
IMPORTANT GENERAL SAFETY INFORMATION – ADDITIONAL SPECIFIC SAFETY ALERTS APPEAR IN THE FOLLOWING INSTRUCTIONS.
⚠ Failure to utilize a properly sized well tank will result in excessive strain on the pump and may ultimately lead to product failure, leaking or flooding or property damage.
⚠ For your safety, the information in this manual must be followed to minimize the rise of electric shock, property damage or personal injury. Properly ground to conform with all governing codes and ordinances.
-
If you are installing an entirely new well system, follow Steps II, III, IV and V. Skip Step I, since you are not removing an existing tank. However, make sure that the power is turned off before you hook up the pressure switch to the household wiring. If you are in any doubt about working with electricity, call a licensed electrician.
-
If you are replacing a plain steel tank with this Water Worker diaphragm tank:
a. A diaphragm tank is pressurized with air at the factory (at a pressure close to that of a car tire). For this reason, it will be smaller than the plain steel tank, even though both tanks deliver the same amounts of pressurized water. Because of this, you may have to adjust the piping to reach the new connections.
b. Install a pressure relief valve at the tank connection to ensure the safety of the system.
c. If you have a deep well submersible pump, remove all the air charging devices from the well system (snifter valves, bleeder orifices, vacuum lines and connection). Then plug the holes where these devices were located (see your owner’s manual for location of these devices). These devices are not needed for pre-charged tanks, and if they are not removed and the holes plugged, air can get into the well system, cause surges, damage the system, and impair performance.
d. If you have a jet pump, remove the fittings and plug the openings where the vacuum or air lines and air volume controls connect to the pump or piping. If not removed and plugged, they can allow air into the pipes which can damage the well system and impair performance.
e. In addition to the above, follow Steps I through V. -
If you are replacing a diaphragm or bladder style tank with this Water Worker diaphragm tank:
a. If the two tanks are the same size, follow Steps I through V.
b. If they are different sizes, follow Steps I through V and also adjust the piping as necessary to accommodate the new size. -
It is good practice to replace the pressure gauge and the pressure switch whenever you replace an old tank. Of course, you can re-use the tank cross assembly if you are replacing a diaphragm tank with another diaphragm tank (including the tank
cross, pressure gauge, pressure switch, pressure relief valve, pipe nipple and drain).
a. If you do re-use a tank cross assembly, skip Step II. In this case, make sure that the tank is installed as closely as possible to the pressure switch. This will make the system operate as efficiently as possible.
b. If you replace the tank cross assembly with new parts when you install the new tank, complete all of the steps in these instructions, Steps I through V.
RELIEF VALVE REQUIRED. A relief valve should be installed which is set to open at excessive pressures (75 psig or more). This will protect the well tank and other system components should the pressure switch malfunction and fail to shut the pump off. The relief valve should be installed at the connection of the well tank to the system piping and have a discharge equal to the pump’s capacity at 75 psig. At least once every 3 years or if discharge is present, a licensed contractor should inspect the temperature and pressure relief valve and replace if corrosion is evident or the valve does not function. FAILURE TO INSPECT THIS VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE OR
PRESSURE BUILD-UP WHICH CAN RESULT IN PRODUCT FAILURE, SERIOUS INJURY OR DEATH AND/OR SEVERE PROPERTY DAMAGE AND VOID THE PRODUCT WARRANTY -
Always make sure that you equip your well system with an appropriate pressure relief valve. Whether you are re-using a
tank cross assembly or assembling a new one, check to make sure that the assembly includes a pressure relief valve that is
capable of discharging the full output of the pump at or below the maximum working pressure of the lowest rated component in the system. See the owner’s manual for your pump for output information. This is vital for safe operation of the system.
How to Install the Tank
Step I: Disconnect and remove the existing tank after turning the power off and draining the system.
Step II: Assemble the new tank cross unit.
NOTE: If you are re-using the tank cross assembly from the old tank skip to Step III.
Step III: Install the new tank cross assembly on the new tank.
- Remove the plastic plug from the elbow at the bottom of the tank. Discard the plug.
- Install the tank cross assembly on the tank. Either use the new tank cross assembly, put together according to Step II above, or reuse the tank cross assembly from the old tank.
- Apply Teflon® tape to the threads at the bottom of the “stem” of the tank cross. Insert the stem in the female threaded fitting on the bottom of the tank. Tighten hand tight then wrench tight. (Fig. 14-15)
Step IV: Install the new tank.
Step V: Turn the power back on. The pump will fill the tank. The system is now ready to use.
EXHIBIT A
IMPORTANT Safety Instructions • Be sure to read.
⚠ IMPORTANT This tank is designed for use with potable water, limited to a maximum pressure of 100 psi and a maximum working temperature of 130°F. Please note: a hot water heater or a boiler in a hydronic heating system will heat water hotter than 130°F routinely. Use a thermal expansion tank for hot water overflow from a hot water heater, or use an expansion tank for hot water overflow in a hydronic heating system. See the owner’s manual for your pump for output information.
⚠ WARNING EXPLOSION OR RUPTURE HAZARD A relief valve must be installed to prevent pressure in excess of local code requirement or maximum working pressure designated in the Product Manual, whichever is less. Do not expose Product to freezing temperatures or temperatures in excess of 200° F. Do not adjust the pre-charge or re-pressure this Product except for any adjustments required at the time of initial installation, especially if Product corroded, damaged or with diminished integrity. Adjustments to pre-charge must be done at ambient temperature only. Failure to properly size the Product or follow these instructions may result in excessive strain on the system lead to Product failure, serious or fatal personal injury, leakage and/or property damage.
⚠ WARNING This Product, like most Products under pressure, may over time corrode. Weaken and burst or explode, causing serious or fatal injury, leaking or flooding and/or property damage. To minimize risk, a licensed professional must install and periodically inspect and service the Product. A drip pan connected to an adequate drain must be installed if leaking or flooding could cause property damage. Do not locate in an area where leakage of the tank or connections could cause property damage to the area adjacent to the appliance or to lower floors of the structure.
⚠ WARNING Chlorine & Aggressive Water: The water quality can significantly influence the life of this Product. You should test for corrosive elements, acidity, total solids and other relevant contaminants, including chlorine and treat your water appropriately to insure satisfactory performance and prevent premature failure.
Note: Inspect for shipping damage and notify freight carrier or store where purchased immediately if damage is present. To avoid risk of personal injury and property damage, if the product appears to be malfunctioning or shows signs of corrosion, call a qualified professional immediately. Current copies of the Product manual can be viewed at www.waterworkerdiy.com. Use proper safety equipment when installing.
⚠ CAUTION As in all plumbing products and water storage vessels, bacteria can grow in this Product, especially during times of non-use. Consult your local plumbing professional regarding any steps you may wish to take to safely disinfect your home’s plumbing system.
⚠ WARNING DANGER! EXPLOSION HAZARD, WHEN THE WELL TANK HAS BEEN IN SERVICE AND A CHANGE TO A HIGHER PRE-CHARGE PRESSURE IS NECESSARY DUE TO A REQUIRED CHANGE IN THE PRESSURE SWITCH SETTING, FAILURE TO FOLLOW INSTRUCTION MANUAL CAN CAUSE A RUPTURE OR EXPLOSION, POSSIBLY CAUSING SERIOUS OR FATAL INJURY, AND/OR PROPERTY DAMAGE.
DO NOT ADJUST THE PRE-CHARGE PRESSURE IF THERE HAS BEEN A REDUCTION OF THE PUMP CYCLE TIME OR THE PRECHARGE PRESSURE COMPARED TO ITS INITIAL SETTING. THIS IS BECAUSE REDUCTION IN PUMP CYCLE TIME CAN RESULT FROM LOSS OF TANK AIR PRESSURE WHICH IN TURN CAN MEAN THERE MAY BE INTERNAL CORROSION AND ANY RE- PRESSURIZATION OR ADDITIONAL PRESSURE COULD RESULT IN RUPTURE OR EXPLOSION, AND/OR PROPERTY DAMAGE.
⚠ WARNING MAXIMUM WORKING PRESSURES. Every well tank is air tested to 125 psig, the maximum working pressure for the well tank line. Should pressures exceed 125 psig, proper selection and sizing of an ASME constructed well tank should be made.
⚠ WARNING RELIEF VALVE REQUIRED. A relief valve should be installed which
is set to open at excessive pressures (75 psig or more). This will protect the
well tank and other system components should the pressure switch malfunction
and fail to shut the pump off. The relief valve should be installed at the
connection of the well tank to the system piping and have a discharge equal to
the pump’s capacity at 75 psig. At least once every 3 years or if discharge is
present, a licensed contractor
should inspect the temperature and pressure relief valve and replace if
corrosion is evident or the valve does not function.
FAILURE TO INSPECT THIS VALVE AS DIRECTED COULD RESULT IN UNSAFE TEMPERATURE
OR PRESSURE BUILD-UP WHICH CAN RESULT IN PRODUCT FAILURE, SERIOUS INJURY OR
DEATH AND/OR SEVERE PROPERTY DAMAGE AND VOID THE PRODUCT WARRANTY.
⚠ WARNING For your safety, the information in this manual must be
followed to minimize the rise of electric shock, property damage or personal
injury. Properly ground to conform with all governing codes and ordinances Do
not use this tank for chemicals, solvents, petroleum products, acids, or any
fluids other than potable water. This can cause premature failure due to
corrosion.
Make sure that the pressure switch in your well system is set low enough to
shut off the pump. If all of the faucets and valves are closed in your
plumbing system and the pressure switch setting is too high, the pump can run
continuously without moving water through the system. This could damage or
burn out the pump.
