Model 355 Installation Instructions

BILGE PUMP FEATURES

• Quick-disconnect base plate for easy installation.

• Nylon Impeller.

• Submersible.

• 3 ft. tinned power leads to insure operation in the wettest conditions.

• Water cooled motor to insure long life.

• Easy transom mount base plate.

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

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. 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 PUMP DRY. 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. When the water level is above the float switch,
the pump will automatically start. 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.

TROUBLESHOOTING

Symptoms Check For

No water pumped
Pump not running

Reduced water flow

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 (Tubing MUST go "UP" from pump to through hull fitting). Low voltage to pump;

check. Battery/wire connections.

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

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

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

Do not pump oil, diesel fuel, gasoline or other flammable liquids with this pump.
