REPLACEMENT BLADDER INSTRUCTIONS
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.

dry air or nitrogen.
DANGER! EXPLOSION HAZARD. IF YOU
ADJUST THE PRE-CHARGE PRESSURE OR
ADD PRESSURE TO A TANK THAT 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 QUALIFIED 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 13-14 psig or slightly above
factory setting.
c. Isolation valve needs to be shut.
d. Pre-charge pressure of tank can now be increased to match
system fill pressure.
e. Open isolation valve and start up system.
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 joint for leakage.
26. Connect tank to system. Open fill-valve and check operation. Always
pre-charge tank before completing this step.
FAILURE TO FOLLOW ALL WARNINGS MAY RESULT IN SERIOUS
