How to Install the ProMariner 240 Battery Charger

Installing the ProMariner 240 battery charger is straightforward, even for DIYers:

1. Step 1: Disconnect batteries and select a well-ventilated, dry location near the battery banks.
2. Step 2: Secure the charger using corrosion-resistant screws and vibration pads.
3. Step 3: Connect each output lead to the corresponding positive/negative terminals of the batteries.
4. Step 4: Plug the input cable into a 120V AC outlet with proper GFCI protection.
5. Step 5: Monitor LED indicators to ensure the charging cycle initiates properly.

Always read the full manual for detailed diagrams and safety notices. Improper installation can void warranties or damage equipment.

Maintenance Tips

Maintaining the ProMariner 240 battery charger is easy but crucial for optimal performance. Here’s how you can maximize its lifespan:

• Monthly Inspection: Check for corrosion on connectors and make sure terminals are tight and clean.
• Ventilation Check: Ensure the mounting area remains free from obstructions for proper heat dissipation.
• Cable Integrity: Inspect wires for damage from vibration or salt intrusion.
• Salt Build-Up Removal: Wipe exterior with a soft cloth and non-corrosive cleaner to prevent salt accumulation.

Never open the sealed unit. It is factory-sealed for a reason—tampering voids warranty and risks shock.
