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.

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.
