3. Level Volt Switch: Rotary knob to select the desired output voltage (12V, 24V, 36V, 48V, 60V, or 72V).
4. Output Terminals: Connect the battery clamps here. Red for positive (+), Black for negative (-).
5. Ampere Control Switch: Rotary knob to set the charging current to Low, Medium, or High.
6. Voltmeter: Displays the charging voltage in Volts.

5. Setup

Before connecting the charger, ensure the area is well-ventilated and you have read all safety precautions.

1. Prepare the Battery: Ensure the battery terminals are clean and free of corrosion. If charging a flooded lead-acid battery, check the electrolyte levels and top up with distilled water if necessary.
2. Connect Battery Clamps:
   • Connect the RED positive (+) clamp to the positive (+) terminal of the battery.
   • Connect the BLACK negative (-) clamp to the negative (-) terminal of the battery.

   Important: Ensure a secure connection. Incorrect polarity can damage the charger, battery, or vehicle.

3. Connect to Power: Plug the AC power cord into a standard 110V AC electrical outlet.

6. Operating Instructions

The BreeRainz IWR-40 offers adjustable voltage and current settings to suit various battery charging requirements.

6.1. Setting Voltage and Current

1. Turn On: Flip the Power On/Off switch to the "ON" position.
2. Select Voltage: Turn the Level Volt knob to select the appropriate voltage for your battery (12V, 24V, 36V, 48V, 60V, or 72V). Refer to your battery's specifications for the correct voltage.
3. Select Current: Turn the Ampere control knob to set the desired charging current (Low, Medium, or High).
   • Maximum Current Output:
     • 12V: 16A (max)
     • 24V: 14A (max)
     • 36V: 12A (max)
     • 48V: 10A (max)
     • 60V: 8A (max)
     • 72V: 6A (max)
4. Monitor Charging: Observe the Ammeter and Voltmeter to monitor the charging process.

6.2. Charging Modes

• Normal Mode: For daily charging of depleted batteries. Set the desired voltage and current using the respective knobs.
• "H" Mode (High Voltage Pulse Repair Mode): This mode is designed to desulfurize lead-acid batteries and restore their balance status and charging performance.
  • To activate, select "H" on the Level Volt knob.
  • It is recommended to use the "Low" rate for charging when in "H" mode for optimal desulfurization.
  • The slower and longer you charge a lead-acid battery in "H" mode, the more effectively sulfates will be removed.

6.3. Important Charging Notes

• This charger does NOT have an automatic power-off function. When the battery reaches full charge, the current will automatically slow down to 0.0 Amperes, but the unit must be manually shut down.
• Always monitor the charging process to prevent overcharging, especially with batteries that are sensitive to it.
• After charging is complete, turn off the charger, then disconnect the battery clamps (negative first, then positive).

7. Maintenance

Proper maintenance ensures the longevity and safe operation of your BreeRainz IWR-40 battery charger.

• Cleaning: Disconnect the charger from power before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the charger in a cool, dry place when not in use. Keep it away from moisture and direct sunlight.
• Ventilation: The charger is equipped with multiple ventilation slots and a cooling fan for effective heat dissipation. Ensure these vents are not blocked during operation to prevent overheating and extend service life.
• Cable Inspection: Regularly inspect the AC power cord and battery clamps for any signs of damage, fraying, or loose connections. Replace if damaged.

8. Troubleshooting

If you encounter issues with your BreeRainz IWR-40 charger, refer to the following common problems and solutions:

• Charger Not Turning On:
  • Ensure the AC power cord is securely plugged into a live outlet.
  • Check the Power On/Off switch is in the "ON" position.
  • Inspect the power cord for damage.
• No Charging Current (Ammeter reads 0):
  • Verify battery clamps are correctly and securely connected to the battery terminals (Red to +, Black to -).
  • Ensure the selected voltage matches the battery voltage.
  • Check if the battery is severely discharged or damaged. Some batteries may not accept a charge if their voltage is too low.
  • Confirm the Ampere control knob is set to Low, Medium, or High, not off.
• Charger Overheating:
  • Ensure the charger's ventilation slots are not blocked.
  • Operate the charger in a well-ventilated area.
  • Reduce the charging current setting if possible.
• Battery Not Fully Charging (or overcharging concern):
  • Remember, this charger requires manual shut-off. Monitor the voltmeter and ammeter. When the ammeter drops to 0.0A, the battery is fully charged, and the charger should be manually turned off.
  • Ensure the correct voltage setting is selected for your battery.
  • The battery itself might be faulty or have reduced capacity.
