Maintenance Tips

• • Make sure the system has proper drainage to prevent water from accumulating in the pipes, especially during winter. This will help avoid freezing and potential damage to the components.

• Winterize the System:

  • If storing the RV in cold climates, properly winterize the system by draining any water and checking freeze protection fluid levels to ensure the system remains protected from freezing.

• Inspect External Heat Exchanger:

  • Regularly check the external heat exchanger for any signs of damage, wear, or clogging. Clean the heat exchanger if necessary to ensure it is transferring heat effectively.

• Routine Performance Checks:

  • Periodically check the performance of the system, ensuring the water flow and heat exchange are functioning properly. If there are any issues with heating or water flow, inspect the heat exchanger for blockages or damage.
