TO AVOID SERIOUS PERSONAL INJURY AND PROPERTY
HAZARDS AND TO ENSURE SAFE USE AND PROPER CARE
OF THIS PRODUCT.
EXPLOSION OR RUPTURE HAZARD. THE
EXPANSION TANK MUST BE OPERATED
SO THAT THE PRESSURE DOES NOT EXCEED THE MAXIMUM
WORKING PRESSURE.
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 leaking could cause property damage to the area adjacent to
the appliance or to lower floors of the structure.
This product can expose you to chemicals
including lead, which is known to the State of
California to cause cancer and birth defects or other reproductive
harm. For more information go to www.P65Warnings.ca.gov.

2. Drain water from bladder.
3. Remove air valve core (Figure 1) to bleed remaining air charge.
4. Remove drain plug (Figure 2).
5. Disconnect system connection.
6. Unbolt and remove system connection after marking flanges in
order to align during reassembly (Figure 3).
7. Unbolt blind flange from tank and attach suitable lifting
equipment to lifting eye. Turn top flange counter clockwise to
wrap bladder around itself.
8. Push bladder flange into tank at system connection.
9. Pull old bladder from tank.
10. Unbolt blind flange (Figure 4) from old bladder and remove
old gasket.
NOTE: Inspect for shipping damage and notify freight carrier or store where purchased immediately if damage is present. To avoid risk of personal

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.

11. Wash down inside walls of tank as necessary.
12. Mop up remaining water.
13. Dry out inside of tank (reversed vacuum cleaner or air line from
a compressor).
14. Clean out any remaining dirt.
15. Examine interior for any rust blisters and remove them.
16. Fold new bladder lengthwise and tape at necessary intervals
(Figure 5).
17. Fold in bladder neck and tape.
18. Rebolt blind flange to new bladder and use new gasket.
19. Working by hand, insert bladder into tank with flange pointing to
opening in system connection removing tape as it is inserted into
tank. Do not remove tape from bladder flange.
20. Find and pull bladder flange into position and remove tape. Check
through top flange opening to assure bladder is not twisted.
21. Rebolt blind flange to tank. Torque to 40 - 50 ft. lbs.
22. Rebolt system connection after aligning flange marks
(Figure 3). Torque to 40-50 ft. lbs.
23. Install drain plug (Figure 2) using a liberal amount of TITE-SEAL
COMPOUND 55 or equal. This connection must be absolutely
airtight.
FAILURE TO PROPERLY SEAL VALVE CAP
WILL RESULT IN LOSS OF PRE-CHARGE
CAUSING TANK TO FAIL.
24. Install air valve core. Charge tank to 2 psig below cut-in pressure
of switch using dry air or nitrogen.
DANGER! EXPLOSION HAZARD. IF YOU
ADJUST THE PRE-CHARGE PRESSURE
OR ADD PRESSURE TO A TANK IS CORRODED OR DAMAGED
OR WITH DIMINISHED INTEGRITY THE TANK CAN BURST OR
EXPLODE, POSSIBLY CAUSING SERIOUS OR FATAL
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
• ONLY ADJUST THE PRE-CHARGE AS DESCRIBED IN THIS
MANUAL WHEN THE TANK IS NEW OR WHEN THE INTEGRITY
OF THE TANK AND LACK OF INTERNAL OR EXTERNAL
CORROSION IS CONFIRMED.
• ONLY LICENSED PROFESSIONALS SHOULD CHECK,
ADJUST OR RE-CHARGE THE PRE-CHARGE OF TANKS.
IMPORTANT: If increasing pre-charge pressure above 55
psig the following steps must be followed:
a. Tank must be connected to the system with isolation
valve open.
b. System must be pressurized to 24-30 psig, matching the pre-
charge setting of the tank.
c. Isolation valve needs to be closed.
d. The pre-charge pressure of the tank can now be increased
to the recommended high pressure setting.
e. Bring system up to pressure and then open the isolation
valve to the tank.
Failure to follow these steps could result in damage to the
bladder and void all warranties.
25. Using soapy water, check the drain fitting threads, air valve core and
flange joints for leakage.
26. Connect tank to system. Open fill-valve and check operation.
Always pre-charge tank before completing this step.
FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT
IN DAMAGE TO THE BLADDER OR DIAPHRAGM AND VOID ALL
WARRANTIES.
