OPERATING INSTRUCTIONS
Pump will self-prime at low or high speeds. Make sure
scoop and inlet line are clear and all connections airtight.
Do not run pump dry for more than 30 seconds. Lack of
water flow may damage impeller. To drain pump, loosen
end cover screws.
SERVICE INSTRUCTIONS
IMPELLER REPLACEMENT: Remove end cover and
gasket. Pull impeller out by grasping hub or blades with
pliers. Replace impeller, gasket and end cover. A light
coating of grease in impeller bore will aid priming on dry
start up. (Use correct Jabsco gasket, a thicker or thinner
gasket may cause impeller damage.) Standard gasket is
0.010" thick.
INSTALLATION INSTRUCTIONS
Engage shaft with drive tang, make sure flange seats
squarely on mounting surface and bolt to engine.
Connect inlet and outlet fittings using pipe compound to
seal threads.
