EVO5 700 HRV HEPA - Maintenance

When the wrench icon () appears on wall control screen, perform the required maintenance, according to the table below.

NOTE: If your unit operates on a 24/7 basis, you will have to perform four maintenances per year, but if, for some reason, your unit is not operating on a 24/7 basis, it will take more time to complete the whole maintenance cycle.

As shown on the table above, the annual maintenance ends the maintenance cycle. After an annual maintenance, the next time the wrench icon will appear on wall control screen, a new maintenance cycle will start.

To perform regular maintenance, you have to:

1. Turn the unit OFF and unplug it.
2. Unlatch and tilt the door from the unit base, then lift it up and set aside.
3. Slide out the heat recovery core, the core bracket and all the filters.
4. Clean inside walls of the unit with a damp cloth, and then wipe a dry one.
5. Remove dust on core using a vacuum cleaner with a soft brush attachment. Wash both core filters under hot water with mild soap. Rinse thoroughly and let dry completely.
6. Reinstall the heat recovery core with its filters. The heat recovery core must be installed BEFORE the core bracket. Reinstall the HEPA filter but before reinstalling the prefilter, look at the installation date on HEPA filter frame. If there are more than 6 months passed, discard the prefilter and install a new one, but keep the HEPA filter.
7. Reinstall the door, plug back the unit and turn it on. NOTE: The unit will return to its previous setting after a 20-second delay for boot sequence.
8. Reset the wall control by pressing simultaneously on ECO and TURBO keys. 

To perform annual maintenance, carry out steps1 to 5 of regular maintenance, then continue with the followings:

1. Allow the heat recovery core to soak for 3 hours in a solution of warm water and mild soap (dishwashing liquid). Rinse carefully, drain off water and reinstall with its filters. The heat recovery core must be installed BEFORE the core bracket. Discard HEPA filter and its prefilter and replace with new ones. Do not forget to write the installation date on the new HEPA filter frame.
2. Check the exterior hood; make sure there are no leaves, twigs, ice or snow that could be drawn into the vent. Clean if necessary.
3. Reinstall the door, plug back the unit and turn it on. NOTE: The unit will return to its previous setting after a 20-second delay for boot sequence.
4. Reset the wall control by pressing simultaneously on ECO and TURBO keys.
