How to clean HRV System Core and Filters

How to Clean Your HRV System: Step-by-Step Guide

1. Identify the Filters: Locate the two filters on the side of your HRV system. These filters need to be cleaned every six months.

2. Remove the Filters: Take out the metal filter first, followed by the core. Note the orientation of the core with the sticker facing the front and an arrow pointing upwards.

3. Clean the Core: Use a little force to pull out the core. Take it to a suitable washing area such as your garden, driveway, kitchen sink, or tub. Avoid using harsh chemicals or washing it in the dishwasher. Rinse the core with water and a mild soap solution.

4. Vacuum the Filters: If the filters are not heavily soiled, you can vacuum them from both sides to remove dust and debris.

5. Wash the Filters: Rinse the filters with water or soak them in a dish soap solution for 15-20 minutes. Ensure the dirt drains out properly by positioning the filters at an angle while rinsing.

6. Dry the Filters: Squeeze excess water from the filters and allow them to air dry for 15-20 minutes.

7. Clean the HRV Core: Remove the filter holders and clean the core using a hand shower. Repeat the rinsing process until the water runs clear.

8. Dry the Core: Leave the core to dry for 30-40 minutes, turning it occasionally to ensure any standing water drains out.

9. Clean the Interior: Use a vacuum and cloth to clean any accumulated dirt or dust inside the HRV system while waiting for the filters and core to dry.

10. Prepare for Installation: Ensure the core is dry and gently wipe off any excess water with a paper towel. Reinstall any components that were removed before cleaning.

11. Install the Core: Place the core back into the HRV system, ensuring the sticker and arrow are in the correct position. Push it lightly into place, leaving a small gap on the sides for proper sealing.

12. Install the Filters: Insert the filters into their holders and close the access panel on the front of the HRV system.

13. Restart the System: Once the panel is closed, the HRV system will automatically start and go through a testing phase with increasing fan speeds.

14. Reset Maintenance Sign: If a maintenance sign appears on the control panel, turn off the system for five seconds and then restart it to clear the indication.

15. Maintenance Complete: Your HRV system is now clean and ready to operate efficiently. Regular cleaning ensures fresh indoor air quality.

By following these steps, you can effectively clean the core and filters of your HRV system, ensuring optimal performance and air quality in your home.
