16. Insert bladder neck into bottom of tank. (Figure 6).
17. Pull out flange neck of bladder and fit on blind flange.
Bladder neck becomes gasket for flange. (Figure 7).

19. Insert bolts by hand into flange and tighten in a cross pattern
to 40-50 foot-pounds. (Figure 8).
20. Install drain plug using a liberal amount of Tite-Seal compound
55 or equal. (This connection must be absolutely air-tight)
FAILURE TO PROPERLY SEAL WILL
RESULT IN LOSS OF PRECHARGE
CAUSING TANK TO FAIL.
21. Install air valve core. Charge tank to equal system pressure
using dry air or nitrogen. (Figure 9).
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 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 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.
22. Using soapy water, check the drain fitting threads, air valve
core and flange joint for leakage.
23. 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 INJURY OR
FATAL PERSONAL INJURY AND/OR PROPERTY DAMAGE
