Xylem JABSCO 18660 Series User manual

OPERATION
Flexible impeller pumps must NOT be run dry, as the
pumped liquid is the lubricant for the impeller. Observe
the outlet and shut off pump as soon as liquid stops
flowing. An automatic level switch is convenient to
control the pump.
The pump cannot run against a closed outlet such as
encountered when using a garden hose type shut-off
nozzle.
Pressure for normal operation should not exceed 20 feet
of head (8.7 psi).
Temperature of pumped liquid may be in the range of
45° - 180°F (7° - 82°C).

APPLICATION
Use for bilge pumping, livewell circulation, washdown
and general pumping requirements. If bilge water
contains significant amount of oil, the standard impeller
should be replaced with impeller No. 6303-0003, which is
an oil-resistant nitrile material.
Pump has a dry prime suction lift of about 4 feet (1.2m)
and a lift to 20 feet (6m) when primed. BE SURE
SUCTION LINES ARE AIRTIGHT.
WARNING
!
Explosion hazard. Do not pump 
gasoline, solvents, thinners or other 
flammable liquids. To do so can cause
an explosion resulting in injury or death.
Light housing gets hot during
operation. Do not touch during
or immediately after operation.
Burns can result.
WARNING
!
Motor runs hot—about 180° is a normal
temperature. Prolonged contact during
operation may cause a burn.

INSTALLATION
The pump must be mounted in a dry location – the motor
is not waterproof and must not be submerged.
SELECTION OF A COOL, VENTILATED location will
generally extend pump motor life. The unit can be
mounted in any desired position. It is best to mount so
that water dripping from a loose port connection will not
wet the motor. The pump head may be rotated 180° on
the motor to change direction of flow.
PLUMBING CONNECTIONS
Pump ports have external 1" hose barb and internal 1/2"
pipe threads. Also provided are two male port adapters
to allow the attachment of 3/4" female garden hose
fittings. Use hose that does not kink when bent and with
sufficient wall thickness to prevent collapse when used
on suction side of pump. Hoses should be routed so that
some water will be retained in pump body to wet the
impeller. Wetting the impeller aids in priming and extends
impeller life. Use a strainer on the intake hose to stop
trash and solids from going through the pump. All hoses
must have air tight connections to enable faster priming.
ELECTRICAL CONNECTIONS
Connect black wire to negative (-) terminal of battery.
The orange wire should run to a fused overload protected
switch or circuit breaker with a 15 amp rating, with a wire
from switch or breaker to positive (+) terminal of battery.
Electrical circuit must be independent of all other
accessories. Failure to connect black wire to negative
and orange wire to positive will result in backwards
motor rotation and possible motor and pump damage.
Correct motor rotation is clockwise looking at shaft end
of motor. Use proper wire size as determined by wire
table below. Should the fuse blow, replace with the same
size fuse after determining reason for blown fuse.

WIRING DIAGRAM
Explosion hazard. If pump is operated in an 
area containing flammable vapors, wire leads
must be joined by insulated mechanical 
locking connectors. Loose or inadequate wire
connections can spark resulting in an explosion.
Property damage, injury or death can occur.

† When replacing a pump body that uses a round end cover (3 hole
pattern) it is necessary to replace the end cover, screws and replace
the gasket with an O-Ring (order keys # 1, 2 & 3).
** For 24V and 32V replacement motors, consult the factory.
6303-0003 Oil resistant “Nitrile” Impeller available separately.
MAINTENANCE
Check wires and connections to be sure corrosion is
not adding additional resistance to the motor circuit
and causing a low voltage condition at the motor. Low
voltage can inhibit motor from starting and cause
fuse to blow. Full voltage should be available to prevent
motor damage.
NOTICE: If pump is idle for extended periods, the impeller
may stick to the pump body, preventing motor rotation
and causing blown fuses. To correct, remove end cover
and impeller, clean body and impeller, then lubricate with
water or small amounts of grease before assembly.
If pump is to be in freezing temperatures, drain by
loosening end cover screws.
A Service Kit, or at least spare impellers, should be
carried aboard to be assured of pumping capability.
DISASSEMBLY
1. Remove end cover screws, end cover and O-ring.
2. Withdraw impeller.
3. Loosen and remove two slotted hex screws, which
attach body to motor.
4. Tap body lightly between ports and remove body
from motor.
5. With a 1/2" diameter dowel, push against the shaft
seal from back (motor) side of the body to dislodge
it from the seal bore.
NOTE: Do not tamper with or disassemble motor.
ASSEMBLY
1. Lubricate seal with water and position it in seal bore
with lip, or hollowed-out side of seal, pointing
towards the impeller bore. With a 1/2" diameter
dowel, push against the shaft seal into its bore until
it contacts the bottom.
2. Lubricate motor shaft and install body on motor.
3. Lubricate impeller bore and, aligning flat in impeller
with flat on motor shaft, install impeller with clock-
wise rotary motion.
4. Install O-ring, end cover and screws.
