How to install the Vevor NMBP11-G750-30-12 bilge pump?

Remove the mounting base, attach the strainer to a flat surface, connect a 19 mm (3/4") hose to the outlet, connect the wires (black to negative, brown/white to positive) with a fuse. Make sure the pump is at the lowest point of the bilge.

What fuse to use for this pump?

Use a fuse of the amperage specified in the specifications table. For this model, the power is 43 W at 12 V, which gives about 3.6 A, so a 5 A fuse may be suitable, but follow the manual's recommendations.

How to clean the pump?

Disconnect the power, remove the pump housing by pressing the tabs, clean the impeller and strainer of debris. Reassemble making sure the tabs are properly engaged.

What to do if the pump does not start automatically?

Check that the foam block under the float has been removed, that the float moves freely, that the electrical connections are correct, and that the battery is charged.

Can I use the pump for liquids other than water?

No, this pump is designed only for water. Do not use for gasoline, oil, or other flammable liquids.

How to test the pump operation?

Turn the test knob clockwise to check manual operation. Supply the pump with water during the test.

Can the pump run dry?

No, never run dry as it may damage the pump.

How to connect the electrical wires?

Connect the black wire to the negative (-) terminal and the brown (or brown-white) wire to the positive (+) terminal of the battery. Use a fuse on the positive wire. Seal the connections with marine sealant.

What to do if the pump pumps little or no water?

Check that the strainer is not clogged, the hose is not kinked, the battery is charged, the connections are not corroded, and the fuse has not blown.

WARNING

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:

The automatic bilge pump can only be used for pumping water. It cannot be used for other liquids. During installation, connect the pump's black wire to the negative (-) terminal and the brown or brown-white wire to the positive (+) terminal.

Use the appropriate fuse.

All wire connections must be sealed with marine sealant.

All wires and connections must be positioned above the bilge water level. Unless necessary, do not arbitrarily remove the insulator. Use marine sealant on all wires. Do not run dry.

WARNING:

• To prevent injury, always disconnect the power source when installing or servicing any electrical product. Do not use the pump to remove gasoline, oil, or other flammable liquids. Always use the fuse amperage rating specified for your pump model. Failure to do so could result in serious personal injury or fire.

OPTIONAL MATERIALS

• 1/2-inch-thick marine plywood block (slightly larger than pump base). Waterproof adhesive (epoxy, silicone adhesive, or fiberglass resin) to mount block. 18-gauge wire (brown, brown-white, and black).

PUMP MOUNTING INSTRUCTIONS

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 present.

Step 1: Press the hasps on both sides of the automatic bilge pump, and the filter away from the bottom of the pump.

NOTE: Before connecting or operating the pump, install the filter correctly. 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 have one pump, it is usually installed in the deepest place of the water line when the boat stops. You must install complete tubes for draining water.

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 a wood block, use Φ 4.0 mm stainless steel self-tapping screws.

B: If you fix the strainer to a metal or fiberglass surface, firstly install a piece of wood on it, then fix the strainer to the piece of wood, then install the filter, and ensure that the two hasps are fastened.

Step 4: Connect a 3/4" ID pipe to the outlet nozzle, and clamp it with a stainless steel clamp. It is recommended to use standard tubes, because they will not tie off by suddenly bending. If using a pipe with a smaller diameter, it will not damage the pump, but will reduce the pump's flow.

Step 5: Wiring. In order to prevent ruin or corrosion of the wire, it is necessary to fasten the ends of the wire and the terminals with insulators or place them at the highest horizontal position as possible. When installing the pump, 18-gauge wire is suggested. If too small a wire is used, it will cause overheating inside, reducing the pressure and affecting the performance of the pump.

NOTE:

1. 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 part of the bilge. Be sure that the pump cover can be removed for cleaning in this position. Glue the plywood to the hull with a waterproof adhesive (epoxy, silicone adhesive, or fiberglass resin). See figure 1.

1. Position the pump in the lowest part of the bilge on a flat, level surface (on the plywood block if it has been

installed) with the outlet pointing toward the transom.

Be sure the outlet nozzle is level. If pointed upward or downward, an air lock may form in the pump. (See Figure 1)

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 the float is still high enough to activate the pump.
2. Mark the location of the three (3) mounting holes with a pencil or scribe.

WARNING: When drilling holes do not drill through the hull!

1. Carefully drill two 1/8" diameter pilot holes in marked area and drive a screw in each hole.
2. 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.
3. Route hose on an upward incline to the thru-hull connector. Avoid kinks in hose that can trap water and airlock the pump. Avoid putting excessive strain on hose, which can damage the pump outlet.
4. Force the hose over the thru-hull fitting 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.

1. When the water level rises above the bottom flat surface of the strainer - 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 bottom surface of the strainer, the float switch's contact point is disconnected, float switch stops working, and then the pump ceases to work.

When the brown wire of the auto bilge pump is connected to the battery positive (+) terminal, the black wire is connected to the battery's negative 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.

1. Using the full length of wire provided (and additional wire if necessary), connect wires to the pump as shown in the diagram. (See Figure 2.)

1. Route wires out of the way and secure them to the bulkhead to avoid pulling.
2. Using butt connectors sized for 18-gauge wire, splice fuse holder 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 Chart at top of sheet.)

Warning: FAILURE TO PROPERLY FUSE AND MAKE THE APPROPRIATE WATERPROOF CONNECTIONS WILL VOID THE PRODUCT WARRANTY.

1. Install a Three-way switch that allows for automatic or manual switching models. 5. Turn the pump on and twist the Test Knob clockwise to check operation. Feed water into the pump. If output appears to be too low, check the wire connections. Reversed connections result in opposite impeller rotation that drastically reduces capacity and can cause premature pump 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 around 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 and not cracked or broken.
• Replace the impeller guard, screw, and pump housing on the base. Be certain 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 pump materials.

Reduced Flow	Plugged strainer	Clean outside of strainer and clean debris from around impeller.
	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
