ports are determined by the direction of shaft rotation (refer
to dimensional drawing). Before installing, energize clutch
and turn pump shaft in direction of shaft rotation. Drive
pump with two "A" size belts. Avoid dry-running by using
Vacuum Switch Model 4732-0000 for automatic shut-off.

WIRING
Connect wires as shown for manual on-off operation.
Install proper size fuse (see Electrical Specification Chart)
in positive lead ahead of switch and as close to power

OPERATION
Pump will self-prime at low or high speeds. Make sure that all
connections are airtight. 12 Volt models are equipped with
mechanical clutch engagement screws in case of electrical failure.
To mechanically engage clutch, loosen locking nuts, tighten allen
head screws and retighten locking nuts. Reverse procedure to
disengage clutch. If the mechanical engagement feature is not
desired, the screws may be removed. DO NOT RUN PUMP DRY
FOR MORE THAN 30 SECONDS. LACK OF WATER FLOW MAY
DAMAGE IMPELLER. To drain pump, loosen end cover screws.
See Head Capacity Table for head pressures and flow. To avoid
costly shutdowns, keep a Jabsco Service Kit on hand.
