Installation
E. If cut-in setting is too low, system will rattle or
develop water hammer when pump starts.
F. Cut-out setting is not as critical as cut-in setting.
Make sure that pump will stop running in a rea son-
able time. If it does not, cut-out setting may need to
be adjusted down slightly. Be sure that after readjust-
ment, system does not rattle or hammer on startup.
7. Re-check tank air pre-charge to be sure it is 2 PSI
below pump pressure switch cut-in setting (see Page 3).
TESTING FOR BLADDER LEAKAGE
1. Disconnect power to pump.
2. Drain all water from tank bladder by opening faucet
closest to tank.
3. Remove valve cap from valve and release all pressure
possible by depressing valve core. When air stops
coming from valve, remove valve core to release
remaining pressure.
4. Disconnect piping from elbow on tank flange.
5. Carefully turn tank upside down or lay it on its side.
Retained water in tank may cause sud-
den weight shift when lowering. Support tank so that
it cannot fall when being lowered or inverted.
6. If bladder leaks, water will run out of valve. If so,
replace bladder.
BLADDER REPLACEmENT
To be sure cover flange cannot blow off of
tank, release all air from system before re moving nuts
from cover flange.
1. Disconnect power to pump.
2. Follow steps 2 through 5 under "Testing For Bladder
Leakage", above.
3. Remove nuts from tank cover flange. Tap cover
flange to break seal and remove.
4. Bladder will not come out in one piece. Hold blad-
der with pliers and cut wherever convenient with sin-
gle edge razor blade or sharp knife. Continue holding
and cutting until bladder is removed.
5. Clean and dry inside of tank.
6. Before bladder can be inserted into tank, it must be
tightly rolled up as follows:
A. Place bladder on clean surface with opening to
one end and flatten to force air out. Pull ends out
flat (see Figure 3).
B. To get tightest possible wrap, start on one side
at top and TIGHTLY roll bladder diagonally to
other side (see Figure 4). To force out as much air
as possible, be sure to roll toward bladder neck
opening.

7. To help insert bladder, sprinkle outside of it with
talcum powder. With tank on its side, push tightly
rolled bladder into tank, hooking bladder neck ring
over edge of tank head.
8. Insert arm in bladder and push sidewalls outward. It
is not necessary to remove all wrinkles from bladder.
NOTICE: Don't push bladder into tank further than
its own length. In a large tank, bladder can slip out of
reach if pushed too far.
9. Clean tank head sealing surface and lip ring groove
of cover flange.
10. Pull lip ring of bladder through tank opening and
seat it against tank head.
11. Clean sealing surface and groove of cover flange;
place on tank (see Figure 5).
