• Quick-disconnect baseplate for easy installation.

• Quick-change motor assembly for easy cleaning and wire routing.

• Strong nylon construction.

• Submersible, w/ 6 ft. tinned power leads to insure operation in the

wettest conditions.

• Waterproof heat-shrink wire connectors [Aftermarket]

• 2 second on delay, 10 second off delay for maximum removal

INSTALLATION
LOCATION: Locate pump at deepest position in the bilge. Keep away from

high heat source; engine, etc. MOUNTING: Mount quick-disconnect
bracket to hull or pad with stainless steel screws. Mount switch if equipped.
Do not drive screws through hull! TUBING: Route smooth I.D.
discharge tubing to a thru-hull fitting well above the water line. AVOID
AIRLOCK & MAXIMIZE PERFORMANCE: Avoid any sagging or loops
in the tubing. Tubing must go up from pump to thru-hull.

ELECTRICAL WIRE:

Use 16GA wire for all circuits. If installation is over 20 feet, use 14GA
wire. Brown pump wire must be hooked to positive power for maximum
flow. Wire is designed to prevent corrosion. Do not cut wires more than 1
inch. Reversed polarity will damage switch. PANEL SWITCH: Attach all
wires to UL Marine approved duty switch with auto-off-manual, rated at or
above 10 amps. FUSE: Install a fuse per pump label specifications .
CONNECTIONS: Wire connections should be made above highest possible
water level. Seal wire connections to prevent corrosion and electrolysis.

OPERATION
DO NOT RUN DRY MORE THAN 5 SECONDS. ALWAYS TEST PUMP

AND SWITCH BEFORE LEAVING DOCK.

MANUAL MODE When brown wire from switch is not hooked up, the pump
float switch is bypassed. To turn pump on, turn switch on. If pump does
not turn on, turn switch off, check power, fuses, connections, wires. Retry. If
pump does not turn on, check pump motor.

AUTOMATIC MODE When the water level is above the float switch, the
pump will automatically start after 2 seconds. It will stop 10 seconds after
the water level falls below the float. If the float becomes jammed with de­bris, the pump will NOT STOP running. Turn the pump switch to the OFF
position. Remove the debris. Reset switch to the automatic or manual
ON position. Test. SWITCH TEST: Turn power ON to pump switch. Use
a quarter or flat head screwdriver wait 2 seconds, and pump turns on.
Lower float and pump turns off after 10 seconds.

TROUBLESHOOTING

Symptoms Check For

No water pumped
Pump not running

Reduced water flow

Runs continuously Check boat for leaks; Clean accumulated debris from float mechanism.

Low flow Polarity reversed [ on pump only ]; check wiring. Use smooth bore (I.D.) discharge tubing only.

WARNING

Reset pump switch. Blown fuse. Reversed polarity damaged switch board.
Wire connections. Impeller or float switch plugged with debris.

Impeller/screen plugged with debris. Pinched/clogged discharge tubing. Discharge tubing sagging below
pump causing air lock (trap). Tubing MUST go "UP" from pump to through hull fitting. Low voltage to pump;
check. Battery/wire connections.

Is through hull fitting I.D. smaller than pump discharge port?

Do not pump oil, diesel fuel, gasoline or other flammable liquids with this pump.
This pump does not prevent the discharge of oil or other chemicals into the water. Please take appropriate
measures to prevent discharging oil or other chemicals and safeguard the environment. Always disconnect
power before servicing pump. Always use fuse size specified in specifications. These bilge pumps are designed
to evacuate standing bilge water only. These pumps may not prevent boat sinkage due to storms, rough
weather, unsafe boating, improper installation procedures or hull damage.
