WARING
CAUTION:
Read all instructions carefully before installing and using this product. This pump is sealed and, therefore, submersible, However, the electric wire connections must not be submerged. For extra protection, coat the butt joints and adjacent wire ends liberally with liquid electrical tape.
SECURITY:
Auto bilge pump can only be used for pumping water. It can not be other liquids while installing, connect the pump's black wire to the next (-) terminal and brown or brown white wire to the positive pole(+).
Use the suitable fuse.
The wire connections must be sealed by marine sealant.
All wires and connections must be above the bilge water level. Unless necessary, please do not arbitrarily remove the insulator. Marine sealant oxidant should be used for all wires. Not dry running
WARNING:
- To prevent injury, always disconnect the power source when installing or servicing any electrical product
● DO NOT use pump to remove gasoline oil or other flammable liqu
● Always use the fuse amperage rating specified for your pump mode
● Failure to do so could result in serious personal injury or fire haze
OPTIONAL MATERIALS
- 1/2"-thick marine plywood block(slightly larger than pump base)
● Water proof adhesive(epoxy, silicone adhesive, or fiberglass resin) to mount block.
● 18-gauge wire (brown brown white and black).
PUMP MOUNTINGINSTRUCTIONS
WARNING: Remove the pump mounting base (See Figure 3)
Remove the foam block that supports the float during shipping.
Failure to do this prevents the pump from starting when water is pre
Step 1: Press the hasps on both sides of the auto bilge pump, and the filter away from the bottom of the pump.
NOTE: Before connecting or operating the pump, install the filter correct. It is strictly prohibited to disconnect
the filter when the pump is running. The pump must be installed above water level.
Step 2: Ensure the best place when installing the pump. If you only one pump, it is usually installed in the deepest place of the water le when the boat stops. You must install complete tubes for draining wa
Drain all sweepers by horizontal installation of water pipes, or placing pump in a higher position.
Step 3: Install the strainer
A: When fixing the strainer on wood block, use 4.0mm stainless steel self-tapping screws.
B: If you fix the strainer to a metal or glass fiber, firstly install a pin wood on it, then fix the strainer to the piece of wood, then install the in the filter, and ensure that the two hasps fastened.
Step 4: Connect a 3/4 "ID pipe to the outlet nozzle, and clamp their stainless steel clamp. Recommend using the standard tubes, because will not tie off by suddenly bending. If using a pipe with smaller dial will not damage the pump, but will reduce the pump's flow.
Step 5: Wire In order to prevent ruin or corrosion of the wire, it is in to fasten the ends of the wire and the terminals by insulators or pla at the highest horizontal position as possible. When installing the pump 18 wire is suggested, If too small wire is used, it will cause overhead inside, reducing the pressure and affecting the performance of the pump
NOTE:
- Make sure the hull thickness is at least 1/2" thick. If not, place a 1/2" marine plywood (slightly larger than the pump base) in the lowest of the bilge. Be sure that the pump cover can be removed for clear this position. Glue the plywood to the hull with a waterproof adhesive (epoxy, silicone adhesive, or fiberglass resin). See figure 1.

Pump Outlet Pointing To Transom Float End Of Pump Transom Level Parallel To Bottom Of Boat Toward Bow ½" Thick Mounting Block Figure 1- Position the pump in the lowest part of the bilge on a flat, level (on the plywood block if it has been
installed)with the outlet pointing toward the transom.
Be sure outlet nozzle is level. If pointed upward or downward, an air may form in the pump. (See Figure 1)
-
The float end of the pump must be level with or above the pump (See figure 1). This prevents the pump from running out of water while float is still high enough to activate the pump.
-
Mark location of the three (3) mounting holes with a pencil or scrib
WARNING: When drilling holes do not drill through the hull!
-
Carefully drill two 1/8" diameter pilot holes in marked area and dr screw in each hole.
-
Slide hose clamps (one to clamp hose to the pump, the other to thru-hull connector) over end of the hose. Force hose over the discharge nozzle of the pump. Install clamp.
-
Route hose on an upward incline to the thru-hull connector. Avoid in hose that can trap water and airlock the pump. Avoid putting excetension on hose, which can damage the pump outlet.
-
Force the hose over the thru-hull boards and clamp into place.
OPERATION:
When the brown white wire of the auto bilge pump is connected to battery's positive (+) terminal, the black wire is connected to the battery-negative (-)terminal, the pump has automatic function.
When the brown white wire of the auto bilge pump is connected to battery's positive (+) terminal, the black wire is connected to the battery negative (-) terminal, the pump has automatic function.
- When the water level rise above the bottom flat surface of the st - 50 mm, the float switch's contact point is connected then the pump works.2. When the water level drops to 20 -30 mm above the bottor
surface of the strainer, the float switch's contact point is disconnected, float switch stops working, and then the pump ceases to work mean when the brown wire of the auto bilge pump is connected to the ba positive (+) terminal, the black wire is connected to the battery's nega terminal, this pump is same as the ordinary bilge pump and has no automatic function.
WARNING INSTRUCTIONS
WARNING: Be certain that power source is 12-volt D.c. /24-volt D.c. voltage will damage the pump
- Using the full length of wire provided (and additional wire if neces connect wires to the pump as shown in the diagram.(See Figure 2.)

12-Volt Battery /24-Volt Battery Suitable Fuse (see chart) Black Brown Automatic line Test Knob Figure 2- Route wires out of the way and secure them to the bulkhead avoid pulling.
- Using butt connectors sized for 18-gauge wire, splice fuse hold into positive lead (brown) between the battery and switch.
Position fuse holder in a location that is easily accessible for changing fuses.
IMPORTANT: Use fuses of the proper amperage (See Specification CI at top of sheet.)
Warning: FAILURE TO PROPERLY FUSE AND MAKE THE APPROPRIATE WATERPROOF CONNECTIONS WILL VOID THE PRODUCT WARRANTY.
- Install a Three-way switch that allows for automatic or manual swit models.5. Turn the pump on and twist the Test Knob clockwise to cl operation. Feed water into the pump. If output appears to be too low the wire connections, Reversed connections result in opposite impeller rotation that drastically reduces capacity and can cause premature pun failure.
CARE AND MAINTENANCE
Occasionally check your pump to be certain debris is not jamming the impeller and/or float within the housing. Use the test knob by rotating clockwise direction, Careful attention will guarantee outstanding pump performance.
- To clean the water chamber remove pump housing from the mount base by pressing in tabs on sides. Lift the pump housing away. Figure 3)
- To clean the impeller, remove the impeller guard screw and lift the impeller guard.
- Remove all debris that has accumulated in pump chamber and aro the impeller. Ensure that all debris is removed from strainer slots around the pump base.
-
Inspect the impeller to ensure that it is firmly attached to shaft an not cracked or broken.
-
Replace impeller guard, screw, and pump housing on base. Be cer that all tabs are fully engaged.
- Periodically check the electrical connections to ensure they are water-resistant and mounted high and dry. Do not use household cleaners on the pump because many of them may damage the p materials. A

| Discharge line plugged | Clean out hose by back flushing | |
| Low battery voltage | Check battery condition and charge if necessary. | |
| Kinked discharge hose | If hose is kinked because of sharp bend,convert to hose which will not kink bends. | |
| No water pumped | Wire connections | Make sure wire Connections are not corroded.Visual check is not enough -a s pull on each wire will tell if the wires are still joined. Check to be sure joins are hanging down into the water. |
| Fuse melted | Check fuse to see that it is the correct fuse still blows,check impeller through inlet opening to be sure it is no jammed or stuck with debris. | |
| Float switch failure | Lift end of float switch up-if pump runs, is OK.If pump does not run, turn Manual SWITCH TO on position-if pu runs automatic switch has failed. | |
| Pump won't shut off | Something under float | Clean under the float to make sure debris not holding the float up |
| Stuck float | Check to see that the float is loose and gummy bilge oil. If float action appears sluggish and/or the float does not move intermittent or sporadic operation of the p may occur.This condition is usually the result of oil and/or Dirt accumulating in a around the movable parts of the switch.To correct try soaking the entire switch In Marine cleaner for ten minutes, agitati several times and checking for smooth air free operation of the float. Repeat if necessary | |
| Switch mounted too Low IMPORTANT | If the pump is sucking air and the autorswitch has not reached the OFF position, the switch may be mounted too low for and should be pump reinstalled at least higher than the pump base. | |
| Wires over-heated. Melted insulation | Combination of jammed impeller and wrong size fuse. | Be sure impeller is clean of debris and to rotate Reduce fuse to proper size Replace damaged wiring and/or switch. |
| Repeated melted fuse | Fuse size or jammed impeller | Be sure fuse has amp rating Check imp to see that it is not bound up by fish I |
