Maintenance (Continued)
4. Replace pressure switch tubing and
motor wiring.
5. Prime pump according to
instructions; see Operation.
6. Check for leaks.
TANK OPERATION CYCLE (MODEL
3P715B)
1. Tank nearly empty–air expands
filling area above vinyl separator
(Figure 24A).
2. Water begins to enter tank–air is
compressed above separator as it
fills with water (Figure 24B).
3. Pump-up cycle completed–air now
compressed to cut off setting of
pressure switch (Figure 24C).
4. Water being drawn from
tank–compressed tank air forces
water out of separator (Figure 24D).
5. Separator completely empty–new
cycle ready to begin (Figure 24A).
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. If bladder leaks, water will run out
of valve. If so, replace bladder. See
instructions below.
BLADDER REPLACEMENT
To be sure cover
flange cannot blow
off of tank, release all air from system
before removing 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 convenient with single
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 25).
b. To get tightest possible wrap,
start on one side at top and
TIGHTLY roll bladder diagonally
to other side (See Figure 26). To
force out as much air as possible,
roll toward bladder neck
opening.
7. To help insert bladder, sprinkle
outside of it with talcum powder.
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.
9. Clean tank head sealing surface
and lid ring groove of flange.
