Installation
B. Reconnect power supply to pump and pump
up pressure in system.
C. Disconnect power supply to pump again and
re-check switch setting.
D. Repeat until pressure switch starts pump
within ±1 PSI of proper setting.
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 set-
ting. Make sure that pump will stop running
in a reasonable time. If it does not, cut-out
setting may need to be adjusted down slight-
ly. Be sure that after readjustment, 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 sudden 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
bladder with pliers and cut wherever conve-
nient with single edge razor blade or sharp
knife. Continue holding and cutting until blad-
der 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 diago-
nally to other side (see Figure 4). To force out
as much air as possible, be sure to roll
toward bladder neck opening.
Roll Diagonally

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 out-
ward. 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).
