4. Setup and Installation

Follow these steps for proper installation of your Lifegard Heater Module:

  1. Select Heater Element: Choose a fully submersible aquarium heater with a diameter of 1-inch or 3/4-inch, suitable for your aquarium size and temperature requirements.
  2. Insert Heater: Carefully insert the chosen heater element into the Lifegard Heater Module. Ensure it is seated correctly within the compression coupling.
  3. Secure Heater: Tighten the compression coupling to secure the heater element firmly in place. Do not overtighten.
  4. Connect Plumbing: The module features an Inlet Port (1 1/4-inch Slip / 3/4-inch FPT) and an Outlet Port (1-inch Slip / 3/4-inch FPT). Connect your aquarium's filtration system plumbing to these ports. Use appropriate PVC solvent for slip fittings or thread sealant for FPT connections. If using 3/4-inch threaded installation, utilize the included reducing bushings.
  5. Position Module: Install the heater module in a vertical position within your filtration system, ensuring proper water flow. The overflow pipe should be at the top to allow air to vent automatically.
  6. Leak Check: Before plugging in any electrical components, fill your aquarium and filtration system with water. Carefully check all connections for leaks. Address any leaks immediately.
  7. Power On: Once all connections are secure and leak-free, and the module is filled with water, plug in your aquarium heater and other filtration equipment.

Note: The port size dimensions listed are pipe sizes. "SLIP" refers to PVC solvent socket type fittings.

5. Operation

The Lifegard AF-92-19 Heater Module operates by directing aquarium water to flow continuously around the installed heater element. This constant circulation ensures efficient heat transfer and maintains a stable, uniform temperature throughout your aquarium.

  • Temperature Monitoring: Monitor your aquarium's temperature regularly with a reliable thermometer. Adjust the setting on your heater element as needed to achieve the desired temperature.
  • "On" Indicator: The clear cap on the module allows you to easily view the "On" indicator light of your heater element, confirming it is receiving power and operating.
  • Air Venting: The integrated overflow pipe automatically vents any trapped air from the heater chamber, preventing air pockets that could hinder performance or damage the heater.

6. Maintenance

Regular maintenance ensures optimal performance and longevity of your Lifegard Heater Module.

  • Monthly Inspection: Visually inspect the module and all plumbing connections for any signs of wear, damage, or leaks.
  • Cleaning: Periodically, disconnect the module (after unplugging the heater and pump) and clean any algae or debris that may have accumulated inside the chamber or on the heater element. Use a soft brush and aquarium-safe cleaning solutions if necessary. Rinse thoroughly with clean water.
  • Heater Element Check: Remove the heater element and inspect it for cracks or damage. Replace damaged heaters immediately.
  • Gasket/O-ring Check: Inspect the compression coupling gasket or O-rings for signs of deterioration. Replace if necessary to prevent leaks.
