INSTALLATION
MOUNTING
Mount upright in a dry location (above highest bilge water
level) on a solid surface. Selection of a dry cool ventilated
location will generally extend pump life. Adjust belt tension
for 1/4 inch play between pulleys.
PLUMBING
For intake and discharge use 3/4” ID non-collapsible hose.
Keep intake and discharge lines free of kinks and restric-
tions. Use a 3/4” bilge strainer (Model 35890-0000) or a 3/4”
in-line strainer (Model 36200-0000) in the intake line from the
bilge to protect pump from debris. Use a 3/4” thru-hull fitting
located above the waterline at all angles of heel or pitch.
WIRING
Wiring pump in a circuit independent of all other electrical
fixtures. Use stranded copper wire. Install fuse/breaker in
positive lead. See table for recommended wire and fuse size.
Model 36680-2 Series
MAINTENANCE
WINTER STORAGE: When possible, it is preferred that the
complete pump be removed and stored in a warm dry place.
If this is not possible, the pump must be completely drained,
hoses removed and pump run until all water is expelled.

WIRING DIAGRAM FOR AUTOMATIC OPERATION
See diagram for wiring connections. Use a 10 amp-rated
switch (44960-Series). After installation, it is recommended
that voltage be checked at the motor terminals with motor
operating under full load. Voltage should not be less than
90% of rated motor voltage.

TROUBLESHOOTING
Problems Causes
Loss of suction to pump — Air leak in suction line.
— Bilge pickup not submerged.
— Intake hose kinked or plugged.
— Fouled intake or discharge value.
— Ruptured diaphragm.
Rough or noisy operation — Intake or discharge hose kinked
or plugged.
— Pump not mounted firmly.
— Loosened eccentric screw.
— Ruptured or collapsed pulsation
dampener.
VALVE REPLACEMENT
1. Remove four bolts securing jack shaft assembly.
2. Expose valves by lifting jack shaft and the attached
diaphragm assembly from pump base. Remove and clean
or replace valves.
3. Install valves, making sure rubber flapper is UP on intake
and DOWN on discharge.
4. Replace motor-mount-diaphragm assembly and fasten evenly
to base with the four tie down bolts and washers.
DIAPHRAGM AND CONNECTING ROD REPLACEMENT
1. Remove four bolts securing jack shaft assembly.
2. Lift jack shaft and the attached diaphragm assembly from
pump base.
3. Remove two diaphragm retainer screws and the bottom
diaphragm retainer.
4. Remove lock nut. Remove connecting rod and diaphragm
from the top of diaphragm retainer, then unscrew bolt to
separate diaphragm plates.
5. Check diaphragm for cuts and cracks. Check rod assembly
bearing for excessive wear. Replace if badly worn.
6. Loosely reassemble diaphragm, diaphragm plates, connecting
rod spacer and diaphragm bolt onto connecting rod. Using lock
nut, firmly secure connecting rod to jack shaft. Secure
diaphragm to upper diaphragm retainer with the bottom
diaphragm retainer and two screws.
7. Tighten connecting rod bolt.
8. Replace motor-mount-diaphragm assembly and fasten evenly
to base with the four tie down bolts and washers.
PULSATION DAMPENER REPLACEMENT
1. Disconnect power leads from pump and remove from mount.
2. Remove nine bottom plate screws and the bottom plate.
Pull out and replace pulsation dampener.
3. Replace bottom plate and screws. Tighten evenly to ensure
an air and water seal.
4. Reinstall pump and reconnect power leads.
