Use the ProSport for charging lead acid batteries only voltage electrical systems other than in a marine application. Do not use the battery charger to charge dry cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and property.

Never charge a frozen battery. Safety Precautions Prior to Charging Batteries

If necessary to remove a battery from a boat to charge, always remove grounded terminal from battery first. Make sure all accessories in the boat are off, as to not cause an arc.

Be sure the area around the charger and batteries is well ventilated while the batteries are being charged. Gases can be forcefully blown away using a piece of cardboard or other nonmetallic material as a fan.

Clean battery terminals with full eye protection to prevent corrosion from coming in contact with eyes.

Add distilled water in each cell until electrolyte reaches levels specified by the battery manufacturer. This helps purge excessive gases from cells. Do not overfill. For batteries without caps, carefully follow manufacturer's recharging instructions.

Study all manufacturer’s specific precautions, such as removing or not removing cell caps while charging, in addition to rates of charge.

Extension cords should be industrial grade / heavy duty U.L. approved and grounded. Check extension cord before use for damage, bent prongs, and cuts. Replace if damaged. Always make your extension cord connection on the charger side first. After connecting the extension cord to the charger then proceed to plug the extension cord to a nearby 120 VAC GFCI protected (Ground Fault Circuit Interrupt) outlet. Always remove the extension cord from the 120 VAC outlet first when charging is completed followed by unplugging the charger.

General Overview

The ProSport charger is a fully Automatic/ Electronic Multi-Stage On-board Marine Battery Charger. ProSport is prewired for easy installation and is 100% waterproof for fresh and salt water applications.

The ProSport incorporates an extruded aluminum housing with plastic end caps. This design offers improved durability and heat transfer while comparing it to full plastic case competitive products. The ProSport offers multi-stage charging which includes a "Float " maintenance mode that is safe for long and short term storage. ProSport can be left on indefinitely without harming or over charging your batteries.

The ProSport's Distributed-On-Demand Multi-Stage Charging Technology will automatically sense and distribute 100% of the available charging amp output,

8,12,or 20 amps (model specific) to any one bank or combination of all banks. Each battery bank output is fully isolated.

Easy to view LED indicators will provide you with AC Power On and Charging Status. The LED Indicators can be seen from the front and side of the charger when installed.

The ProSport is available in 5 models and can be used in 12,24, and 36 volt (model specific) configurations without rewiring or switching. Just attach the DC output cable terminals as illustrated in the installation section of this manual.

Trouble Shooting Guide

|No Red or Green LED Indicator

Check for loss of AC power at the 120VAC Outlet. Confirm GFCI (Ground Fault Circuit Interrupter) has not tripped. Check with a meter or 120VAC test light that AC is present at the end or your extension cord.

Confirm all charger cables are installed with the correct polarity connections at each battery and that all connections are clean and tight.

With the AC Power removed and the engine off, check the charge level of each battery with a DC meter or Handheld DC Tester. If there is no charge level indication for a battery, check each battery with a hydrometer to determine if it has one or more bad cells. (batteries should always be replaced in sets, and always the same type.)

If everything above checks out ok, contact ProMariner for product service.| |---|

|Battery is Not Charging, Red and Green Indicator is “on”

Confirm all charger cables are installed with the correct polarity connections at each battery, and that all connections are clean and tight. connections will blow output fuse, resulting in no output voltage.

With the charger on, read DC voltage at each battery. If any of the readings are less than 13 VDC Proceed with the following:

A. Disconnect AC power at the 120VAC outlet.
B. Remove charger cables from each battery.
C. Reconnect AC power and read DC Voltage across each output cable, if output voltage is approximately 14.5VDC the charger is ok and each battery should be tested with a hydrometer with the charger and engine off to determine if one or more batteries have bad cells. (batteries should always be replaced in sets, and always the same type.)
D. If there is no output when trying to read DC voltage check each output fuse and replace as needed.

If the DC voltage at each charger output there is less than 14.0 volts contact ProMariner for product service.| |---|
