L1600 ProSeries Livewell/Baitwell Pump

12 or 24V Model

Installation Instructions

Important: Read before attempting Installation

The L1600 Livewell/Baitwell Pump has been designed for pumping water in a marine

environment. The pump is not to be used for pumping any other liquids other than

water/seawater. Pumping other liquids can result in personal damage/injury and/or

property damage.

Security

The Livewell/Baitwell pumps are designed to simply install into any valve fitting with 1”

NPT Male threads.

The pump may not be used for other liquids than water/sea water

Always install the pump according to the wiring instructions

Always use the fuse required per pump label.

The wire connections must be sealed with a marine sealant

Insulation or cable sheathings must be placed above the highest water level

Do not run dry for extended periods

Installation:

Please follow the installation instructions carefully to ensure maximum efficiency in your

Livewell/Baitwell pump operation.

1) Pump should be installed below the water line to ensure a flooded suction to the

pump.

2) Install a 1” seacock below the waterline in your boat. Warning: Failure to install a

seacock may subject your vessel to flooding.

3) Install a thru hull pickup with a filter grate to reduce or eliminate debris from

entering the seacock and ultimately your Livewell/Baitwell pump.

4) Install your seacock and Livewell/Baitwell pump using pipe tape sealant such as

Teflon tape on all threaded connections.

5) Attach Teflon tape or pipe tape sealant to a 1” NPT nipple that will screw on to

your Livewell/Baitwell pump on one side and the other side to your 1” seacock.

The Livewell/Baitwell pump is equipped with 1 1/8” or 1 ¼” Barbed ports. The port

threads into the discharge area of the pump. Make sure to apply thread sealant to the port

threads. Tighten port until port is bottomed out with pump body. If the

Livewell/Baitwell pump is to be mounted in a horizontal position, make sure the

discharge is pointing in an upward position to allow air to vent.

1) Fasten your reinforced hose from the pump port to the LiveWell/Baitwell tank.

Avoid sharp bends or loops. Support the hose if necessary. Note: In order to prevent

air locks it is important that the hose is not to be allowed to dip below the pump

outlet. The hose should be constantly rising.

Install seacock below waterline

Install a 1" seacock below the waterline. Failure to do so risks vessel flooding.

Install thru hull pickup with filter

Install a thru-hull pickup with a filter to prevent debris from entering the pump.

Use pipe tape sealant on threaded connections

Apply pipe tape sealant (e.g., Teflon tape) to all threaded connections for a secure seal.

Connect pump to seacock with NPT nipple

Connect pump to seacock using a 1" NPT nipple with thread sealant.

Install discharge ports and orient for venting

Install discharge ports with sealant. Orient horizontally mounted pumps upward for air venting.

Connect hose to tank, avoid air locks

Connect hose avoiding sharp bends. Ensure hose rises constantly from pump outlet to prevent air locks.

Security and Usage Guidelines

1 NPT Male thread compatibility

Pumps are designed for 1" NPT male threaded fittings for simple installation.

Use only for water;seawater

Crucial warning: Pump must only be used for water or seawater, not other liquids.

Follow wiring instructions

Always adhere to the provided wiring instructions for proper and safe installation.

Use correct fuse

Ensure the correct fuse, as specified on the pump label, is always used for protection.

Seal wire connections

Seal all wire connections with marine sealant to prevent oxidation and ensure longevity.

Place wiring above water level

Install insulation and cable sheathings above the highest water level to prevent electrical hazards.

Avoid running dry

Do not operate the pump dry for extended periods, as this can cause damage.

Pump Operation and Maintenance

Flood pump with water

Open the seacock to allow water entry and flood the pump before operation.

Check for leaks

Critically check for any leaks from the intake or discharge during installation and operation.

The tank will fill until water reaches the overflow pipe; the pump exchanges water continuously.

Turn off pump when done

Turn off the pump once fishing is completed and the tank is ready to be drained.

Close seacock when not in use

Close the seacock when the pump/system is not being used, especially for extended periods.

Optional Washdown Port

Connect washdown pump

Remove plug and attach washdown pump to the side port using sealant. Ensure seacock is open.

The L1600 ProSeries Livewell/Baitwell Pump is a specialized pump designed for marine environments, specifically for pumping water or seawater. It is available in 12V or 24V models.

Function Description:

The primary function of this device is to circulate water in livewells and baitwells on boats, ensuring a continuous supply of fresh water to keep fish and bait alive. It is designed to be installed below the waterline to ensure a flooded suction, which is crucial for its efficient operation. The pump facilitates the exchange of water in the tank, with old water overflowing and new water continuously entering as long as the pump is running.

Important Technical Specifications:

Voltage: Available in 12V or 24V models.
Thread Type: Designed for simple installation into any valve fitting with 1" NPT Male threads.
Port Sizes: Equipped with 1 1/8" or 1 ½" barbed ports for discharge.
Washdown Port: Includes a ½ NPT side port for attaching an optional washdown pump.
Material: The manual implies a robust construction suitable for marine environments, though specific materials are not detailed.
Safety Certifications: When carrying a CE mark, it conforms to ISO 8846: 1990/electrical Devices - Protection Against Ignition of Surrounding Flammable Gases.

Usage Features:
